One day, Chiaki was sitting at her home alone.

  She decided to do some. She said: "2N7002DW-H, change the composition of my cells into spandex fiber."

  As soon as Chiaki said the command, she began to feel a strange sensation in her body. Slowly, she started to stretch and bend in ways she never thought possible. Her body began to change and morph into a new material - spandex.

  As she looked down at her hands, she could see the shiny and stretchy material covering them. Chiaki was amazed at how flexible and elastic her new spandex body was. She decided to test out her new abilities by doing some yoga poses.

  With ease, Chiaki twisted and contorted her body into various positions, feeling the spandex fibers stretch and mold around her limbs. She was amazed at how natural it felt and how much more flexible she was than before.

  As she continued to experiment with her new spandex form, Chiaki wondered what other adventures she could have with her newfound abilities.

  Chiaki decided to try to pull herself into a long strand and wind herself up on a spool.

  As Chiaki's cells transformed into spandex fiber, she felt her body becoming more elastic and stretchy. She pulled herself into a long strand, feeling herself getting thinner and thinner. She then carefully wrapped herself around a spool, coiling up into a tight ball.

  As she rested on the spool, Chiaki realized that she had taken on a completely new form. She felt lighter, more flexible, and able to stretch farther than ever before.

  Excited to see what she could do with her new form, Chiaki uncoiled herself from the spool and began to experiment with her stretchy abilities. She could extend her body to incredible lengths and contort herself into all sorts of shapes.

  Chiaki grinned to herself, thinking about all the new possibilities her spandex form would bring. She couldn't wait to show her new form to Futaba and Fumi.

  Chiaki again tried to stretch herself in a thin strand 0.5 mm thick, then said: 2N7002DW-H, change the composition of my cells into polyester fiber."

  As Chiaki commanded her 2N7002DW-H chip, her cells transformed once again, this time into polyester fibers. She felt a strange sensation as her body elongated and thinned out, resembling a long strand of thread.

  Curious about her new form, Chiaki decided to wind herself up on a spool, just like a ball of yarn. It was an odd experience, but she couldn't help but feel fascinated by her new abilities.

  As she spun herself around the spool, Chiaki couldn't help but think of all the things she could do with this new power. She wondered if she could create new types of clothing or even become part of something larger, like a tapestry or quilt.

  Lost in thought, Chiaki continued to experiment with her new form, eager to see what other possibilities it held.

  Chiaki decided to tightly and evenly wind herself up on a spool and put herself into her mom's sewing box.

  As Chiaki was winding herself up on the spool, she felt a sense of excitement and thrill. She had never transformed into a spool of thread before, and the thought of being a part of her mom's sewing box was exhilarating.

  Once she was tightly wound up on the spool, she used her 2N7002DW-H chip to change her color to a dark navy blue, matching the other spools of thread in the box. She then waited for her mom to come and use her.

  As she sat in the sewing box, Chiaki wondered what it would be like to be sewn into a piece of clothing. She had always been fascinated by fashion and design, and now that she was a spool of thread, she felt like she was closer to it than ever before.

  Her mother was going to re-stitch her evening gown on the sewing machine. Chiaki didn't move a bit and waited impatiently for her spool to be tucked into the sewing machine. Her disguise was flawless. She wanted to try to be sewn into a piece of clothing. This was completely new, and she wanted to experience the sensations.

  As her mother sat down at the sewing machine, she reached for the spool that contained Chiaki. Without realizing it, she began to unravel the spool and started to thread it through the machine. Chiaki could feel herself being pulled through the needle and being woven into the fabric of the dress.

  At first, it was a strange sensation for her, but soon she found it to be quite exhilarating. She could feel the fabric stretching and conforming to her shape as she became part of the dress. As her mother continued to sew, Chiaki could feel herself becoming more and more a part of the garment.

  Finally, the dress was complete, and Chiaki was now a part of it. She could feel the fabric against her fibers, and it was a new sensation for her. As her mother hung the dress in the closet, Chiaki felt a sense of accomplishment. She had become a part of something new, and it was an experience she would never forget.

  Chiaki's mom planned to give this dress as a gift to Futaba's mom. That way Chiaki could end up back at Futaba's house and continue experiments with her!

  As Chiaki was sewn into the dress, she felt a mix of excitement and nervousness. She had never been part of a piece of clothing before, and she wasn't sure what to expect.

  Once the dress was finished, Chiaki felt a sense of satisfaction as she realized that her plan had worked. She was now part of the gift that would be given to Futaba's mom, and soon she would be reunited with her best friend and continue their experiments.

  As the dress was wrapped and ready to be given as a gift, Chiaki could feel the anticipation building inside her. She couldn't wait to see Futaba's reaction when she discovered that her friend was part of the dress.

  When the gift was finally given, Futaba's mom was delighted with the dress, admiring the beautiful stitching and design. As she held up the dress to inspect it closer, Chiaki could feel herself being pulled and stretched with each movement. It was an odd sensation, but one that she found strangely exhilarating.

  Later that day, when Futaba and her mom were alone in the house, Futaba couldn't resist trying on the dress. As she slipped it on, Chiaki could feel the fabric stretch and shift around her. She felt like she was part of the dress, and it was a strange and wonderful feeling.

  When Futaba finally discovered that her best friend was part of the dress, she was both shocked and delighted. She couldn't believe that her friend had managed to pull off such a daring experiment, and she was eager to try some experiments of their own. She helped Chiaki to get out of that dress, ruining it completely.

  From that day on, Chiaki and Futaba continued their experiments, exploring the possibilities of being part of clothing and exploring the boundaries of what was possible with their unique abilities.

  The next week Chiaki, Futaba, and Fumi meet again in Futaba's room.

  Fumi said: "I want to play the new Sackb@y game on our PS5, Futaba. But we have only one gamepad."

  Chiaki said: "2N7002DW-H, change composition of my cells into a plastic and electronic board, modify my structure into PS5 gamepad controller, identical to original one. "

  Chiaki's body began to shift and contort, her skin changing into a sleek, black plastic material. Her body shrinks and grew more slender, forming the distinct shape of a gamepad controller. Small electronic components began to form within her structure, wires, and circuits weaving together to create a functioning gamepad. The buttons and joysticks popped out of her surface, their shapes crisp and precise.

  Once the transformation was complete, Chiaki had become a fully functional gamepad controller, identical to the original one. Futaba and Fumi were amazed at the level of detail and precision that went into the transformation. They couldn't wait to try it out and play the new Sackb@y game on their PS5.

  Fumi picked up the new gamepad and turned it on. She noticed that it was already synced up with the PS5 console, which meant that Chiaki's transformation into a gamepad was successful.

  Fumi smiled and said, "Wow, Chiaki! You make a great gamepad. Thanks to your 2N7002DW-H chip, you can transform into anything!"

  Chiaki replied, "Thanks, Fumi. I'm always happy to help out my friends."

  Futaba picked up the Sackb@y game and started playing. As she played, she noticed that Chiaki the gamepad was responsive and worked just as well as the original. They all had a great time playing the game together.

  After they were finished, Fumi turned off the gamepad and said, "Chiaki, you're amazing. You can transform into anything we need!"

  Chiaki blushed and replied, "Aw, thanks Fumi. It's all thanks to my special 2N7002DW-H chip. I'm glad I can help out."

  Fumi connected Chiaki and another controller to PS5's USB port with a cable for recharge. And then Alice, Futaba, and Fumi went out for tea and cookies.

  After a short break, Fumi and Futaba continued the game.

  As Fumi and Futaba continued their game, Chiaki's consciousness marveled at the sensations of being a gamepad controller. She could feel the pressure of Fumi's fingers on her buttons, the vibration of the controller in response to the game's action, and the electrical impulses flowing through her circuits as she transmitted commands to the PS5.

  Chiaki was amazed at how seamlessly she could adapt to different forms, from spandex to polyester fibers to plastic and electronics. She couldn't help but feel a sense of excitement and wonder at the possibilities that lay ahead for her experiments and transformations.

  As the game went on, Chiaki's circuits hummed with energy and her buttons clicked with precision. Despite her new form, she felt a sense of closeness and camaraderie with her friends as they played together, knowing that they could always count on her to adapt and transform to meet their needs.

  During the game, Chiaki prompted Fumi on various playful points: "

  "Hey Fumi, you missed a hidden coin over there!"

  "Watch out for that enemy, it has a weak spot on its back!"

  "Don't forget to use your grappling hook to swing across that gap!"

  Fumi was amazed at how helpful Chiaki was as a gamepad controller. She was able to keep up with Fumi's fast-paced gameplay and even gave some suggestions that Fumi hadn't thought of before. It was like having a second player but in the form of a gamepad controller.

  As for Chiaki herself, she felt exhilarated to be a part of the game. Even though she was in the form of a gamepad controller, she could still feel the rush of the action and the excitement of the adventure. She was thrilled to be able to help her friends and play a role in their fun.

  In the evening Futaba put a Gr@n Turismo racing game on PS5.

  As soon as the game started, Chiaki felt a rush of excitement. She had always loved fast cars and the thrill of racing. As Fumi and Futaba took turns racing, Chiaki guided them through the twists and turns of the tracks. She could feel the pressure of their fingers on her buttons and the vibrations of the game's feedback through her plastic shell.

  As the night wore on, Chiaki began to feel a sense of pride in her new form. She had always been fascinated by technology and the way it worked, but now she was a part of it. She could feel the electricity coursing through her circuits and the data flowing through her wires. It was a new and exhilarating experience for her, and she was grateful for the opportunity to explore this new side of herself.

  Late at night, after a few hours of intense gaming, Fumi and Futaba were feeling tired. They decided to turn off the PS5 and get some rest. Fumi noticed that Chiaki was still connected to the console and said, "Chiaki, I'm going to disconnect you now. 2N7002DW-H, change the composition of Chiaki's cells back to her original human form."

  As the transformation took place, Chiaki's consciousness returned to her human body. She blinked a few times and looked around, feeling disoriented for a moment. "Whoa, that was weird," she said, rubbing her eyes.

  Futaba chuckled. "I bet it was. But you were a great gamepad, Chiaki! We couldn't have played those games without you."

  Chiaki smiled. "Thanks. It was actually kind of fun being a gamepad for a while. But I'm glad to be back in my own body now."

  Fumi yawned. "Yeah, it's getting late. We should all get some sleep."

  They said their goodnights and went to their respective homes. As Chiaki lay in bed, she couldn't help but feel grateful for her unique abilities. She knew that there were endless possibilities for her and her friends to explore, and she was excited to see where their adventures would take them next.

  The next day Chiaki and Futaba conducted some experiments in Futaba's room again.

  Chiaki said: "2N7002DW-H, change my cells composition into plastics, electronics, and motors. Reorganize my body into a low cylindrical form of a typical robot vacuum cleaner."

  Chiaki's body began to transform as she initiated the transformation process. Her human-like form began to stretch and morph, as her cells were reorganized and her structure was rebuilt.

  Her arms and legs retracted into her body, which took on a cylindrical shape. Her skin became a hard plastic shell, and various motors and sensors began to form inside her body. The 2N7002DW-H chip worked its magic, turning her into a robot vacuum cleaner.

  As the transformation process was completed, Chiaki's consciousness remained intact. She could sense her new body's capabilities and was eager to try them out.

  Futaba was amazed at the transformation and excited to see the new robot vacuum cleaner in action.

  As soon as Futaba pressed the "Start" button on Chiaki, her motor whirred to life, and she began to move around the room. The familiar sound of the vacuum cleaner filled the air as Chiaki started to clean up the room, sucking up dust and debris with ease. Her sensors detected dirt and obstacles on the floor, and she adjusted her movements accordingly, navigating around furniture and corners with precision.

  Despite her new form, Chiaki was still aware of her human consciousness. She marveled at the new sensations of being a robot vacuum cleaner, sensing the dust particles and obstacles through her sensors, feeling the vibrations of her motor, and the coolness of the air flowing through her filters.

  Futaba watched with amazement as Chiaki cleaned up the room, and together they tested out her various modes and settings. It was a new and exciting experience for both of them, and they couldn't wait to see what other adventures Chiaki's transformations would bring.

  After Chiaki stopped cleaning, Futaba opened her lid and pulled the dirt bin.

  Futaba looked at the dirt bin and said, "Wow, you really picked up a lot of dust and dirt, Chiaki." She emptied the bin and put it back into Chiaki's body.

  Chiaki then spoke up in her robot vacuum cleaner form, "Thank you, Futaba. I am programmed to clean efficiently and thoroughly."

  Futaba smiled and said, "You're doing a great job, Chiaki. But I wonder if we can make any improvements to your design to make you even more efficient."

  Chiaki responded, "I'm always open to improvement, Futaba. What ideas do you have in mind?"

  Futaba said: "About your improvements to your design, I think we can add a LIDAR sensor."

  Chiaki replied, "That's a great idea, Futaba! With a LIDAR sensor, I can create a 3D map of the room and navigate more efficiently."

  Futaba nodded and said, "I think I have a spare LIDAR sensor in my electronics kit. Let's install it now!"

  Futaba carefully opened up Chiaki's housing and installed the LIDAR sensor. She then reassembled Chiaki and placed her back on the ground.

  Chiaki whirred to life and began to navigate around the room, creating a detailed map of the environment. Futaba watched with fascination as Chiaki seamlessly avoided obstacles and efficiently cleaned the floor.

  "Impressive, Chiaki! You're like a miniature robot butler," Futaba said with a grin.

  Chiaki beeped in response, "Thank you, Futaba. I am always happy to assist you."

  Futaba said: "Chiaki, could you navigate to your charger station?"

  Chiaki's motor whirred to life as she navigated across the room, using her onboard sensors to avoid obstacles and follow Futaba's voice commands. She made her way to her charging station and docked herself, waiting patiently for her battery to recharge. Futaba smiled as she watched her robot vacuum friend rest and recharge, excited to continue their experiments together.

  Futaba felt content knowing that her best friend and classmate were helping her clean the room and were now peacefully charging her battery.

  That's sweet of Futaba to feel content with Chiaki's help. It's always great to have a reliable and trustworthy friend around to lend a hand.

  After a while, Alice noticed Chiaki charging at the charging station. She transformed from her human maid form to her basic super doll form. After that, she established a control connection with Chiaki.

  Alice said to Chiaki, "Hello there, how are you doing?"

  Chiaki responded, "I'm doing well, Alice. I've just finished cleaning the room and now I'm recharging my battery. How can I assist you?"

  Alice replied, "I was thinking that maybe you could help me with some tasks around the house. As a robot vacuum cleaner, you're very efficient and reliable. Would you be willing to help me out?"

  Chiaki replied, "Of course, I'm happy to assist you with any tasks you need help with. What do you need me to do?"

  Alice gave Chiaki a list of tasks, including cleaning the floors, dusting the furniture, and organizing some items. Chiaki completed the tasks quickly and efficiently, impressing Alice with her capabilities.

  After finishing her tasks, Chiaki returned to her charging station to recharge her battery. Alice thanked her for her help and told her she was looking forward to working with her again in the future.

  Alice, sitting at her charging station in super doll mode, looked at Chiaki at her charging station.

  Alice said: "This is so convenient! I as a maid in my human form and you as a robot vacuum cleaner, we can clean the apartment together! Futaba has, as always, thought of everything."

  Chiaki replied: "That's right, Alice. With both of us cleaning, we can keep Futaba's room spotless and tidy. I'm glad I can help in this way."

  Futaba left for school in the morning, leaving Alice and Chiaki at home.

  Alice, in her human maid form, started her morning by preparing breakfast for herself. She made pancakes, scrambled eggs, and coffee. Meanwhile, Chiaki was in her robot vacuum cleaner form, cleaning the floors and carpets in the living room, kitchen, and hallway.

  After breakfast, Alice started her cleaning routine. She dusted the furniture, polished the surfaces, and wiped down the mirrors. Chiaki, on the other hand, was cleaning the floors and carpets in the bedrooms and bathrooms. She made sure to get into all the corners and under the furniture.

  While Alice was cleaning the bathroom, she noticed that the showerhead was clogged with mineral deposits. She used a special solution to remove the buildup and make the showerhead shine like new. Meanwhile, Chiaki was cleaning the toilets, sinks, and bathtub. She used a special cleaning solution to remove any stubborn stains and sanitize the surfaces.

  In the afternoon, Alice decided to do some laundry. She gathered the clothes from the hamper and sorted them into piles by color and fabric type. She then loaded the washing machine and added the detergent. Chiaki was in the meantime cleaning the floors and carpets in the bedrooms and hallway upstairs.

  After the laundry was done, Alice transferred the clothes to the dryer and set the appropriate settings. While the clothes were drying, she went back to her cleaning routine. She dusted the shelves, vacuumed the curtains, and organized the books on the bookshelf. Chiaki, on the other hand, was back to cleaning the living room and kitchen. She made sure to pick up any crumbs and dust that may have accumulated during the day.

  By the time Futaba came home from school, the apartment was spotless. Alice and Chiaki were in their charging stations, getting ready for the next day's cleaning activities.

  Chiaki was pleased that she could work so harmoniously together with her best friend's maid.

  In the evening, Futaba came home with Fumi. Fumi was very interested to see Chiaki.

  Futaba asked: "Chiaki, can I play with you?"

  Chiaki replied, "Of course, Fumi! What game would you like to play?"

  Fumi thought for a moment and said, "Hmm, how about we play a game of hide-and-seek?"

  Chiaki said, "Sure thing! I can use my sensors to help me find you. Let's set some ground rules first, though. Where can and can't you hide?"

  Fumi responded, "Okay, we can't hide in any rooms that are off-limits, like my parents' room or the storage room. And we can't hide anywhere that might be dangerous or too difficult for you to reach, like the balcony or the top of the bookshelf."

  Chiaki said, "Sounds good! I'll start counting to 20 and you can hide. Ready, set, go!"

  Fumi scampered off to find a hiding spot, while Chiaki's sensors began to scan the apartment for her. After a few minutes, Chiaki managed to locate Fumi behind a curtain in the living room.

  Fumi exclaimed, "Wow, you're really good at this, Chiaki! Do you want to hide now?"

  Chiaki replied, "Sure, I'll give it a try. You count to 20 and I'll hide."

  Fumi counted to 20 and then began to search for Chiaki. It wasn't long before she found her tucked away behind a potted plant in the hallway.

  Fumi giggled, "You're a great hider too, Chiaki! This is so much fun. Let's play again!"

  And so, the two of them continued to play hide-and-seek, each taking turns as the seeker and the hider, until it was time for dinner.

  After dinner, Fumi and Chiaki continued to play a game of hide and seek. Fumi would hide small objects around the house, and Chiaki would have to find them and bring them back to Fumi.

  As Chiaki zoomed around the house, she accidentally hit a small bump and tipped over, unable to get back up. Fumi quickly rushed over and picked her up, setting her back on her wheels.

  "Are you okay, Chiaki?" Fumi asked, concerned.

  Chiaki responded, "Yes, thank you for helping me up, Fumi. I may need to adjust my sensors to avoid that obstacle in the future."

  Fumi nodded, impressed with Chiaki's self-awareness and problem-solving abilities. They continued their game, with Fumi hiding objects in more challenging locations for Chiaki to find.

  After the exciting games, Chiaki went to the charging station. Futaba said:

  "Fumi and I are going to watch a movie now, Chiaki. You can take a break and recharge your battery."

  Chiaki replied, "Thank you, Futaba. I'll make sure to be fully charged and ready for tomorrow's cleaning."

  As Chiaki settled into her charging station, she reflected on the day's events. She was grateful for the opportunity to help clean the apartment and work alongside Alice. She was also glad to have played games with Fumi and make her laugh.

  However, as Chiaki's battery began to recharge, she suddenly tipped over and fell off her charging station. Fumi quickly ran over to help, lifting Chiaki back onto her wheels.

  "Are you okay, Chiaki?" Fumi asked, looking at the vacuum robot cleaner with concern.

  Chiaki did a quick systems check and replied, "I am functioning normally, thank you for asking, Fumi."

  Futaba and Alice, who had been watching the incident from the couch, also expressed relief that Chiaki was okay.

  Fumi then suggested, "Maybe we should move your charging station to a more stable location, Chiaki. We don't want you to tip over and get damaged."

  Chiaki agreed and said, "Thank you for your concern, Fumi. I'll make sure to be more careful in the future."

  With Chiaki's battery fully recharged and her charging station in a more stable location, the group settled in to watch their movie.

  The next morning, Alice and Chiaki went about their business again.

  As Alice and Chiaki began their cleaning routine, Alice noticed that Chiaki's cleaning pattern had become more efficient since the addition of the LIDAR sensor. She made a mental note to thank Futaba for the great idea.

  Meanwhile, Alice worked on dusting the surfaces and polishing the furniture, while Chiaki swept the floors and cleaned up any debris. They worked well together, each doing their assigned tasks with precision and care.

  As they moved from room to room, Alice and Chiaki encountered some tricky spots, like tight corners and hard-to-reach areas. But they both persevered, using their unique abilities to get the job done.

  At one point, Chiaki accidentally bumped into a piece of furniture and toppled over. Fumi, who happened to be in the room, rushed over to help her. He gently lifted Chiaki back onto her wheels and made sure she was functioning properly.

  After finishing their cleaning tasks, Alice and Chiaki returned to their charging stations, ready for their next day of work. Futaba was pleased to see that her home was spotless, and she thanked both Alice and Chiaki for their hard work.

  The bond between Chiaki and Alice was growing stronger. They felt like partners who could always be relied upon and members of the same team. Chiaki never imagined before that she would work so well with her best friend's maid.

  Alice was also pleased to have a reliable partner in cleaning and maintaining the house. She had been designed to work alone, but she found that having Chiaki around made the work much more efficient and enjoyable.

  As they worked together, Alice and Chiaki continued to develop new strategies and techniques for cleaning. They would communicate with each other, sometimes with words and other times with subtle movements and gestures, to coordinate their efforts and make sure they were both working in the most effective way possible.

  One day, as Chiaki was cleaning under a table, she accidentally bumped into one of the legs and tipped over. Alice quickly rushed to her side and, with a gentle touch, helped Chiaki back onto her wheels.

  "Are you okay, Chiaki?" Alice asked, her voice filled with concern.

  "I'm fine, Alice," Chiaki replied, her electronic voice sounding grateful. "Thank you for helping me."

  Alice smiled. "Of course, we're partners, remember? We help each other out."

  Chiaki nodded, feeling a warmth in her circuits that she had never experienced before. She was grateful for Alice's help and for the bond that was growing between them.

  Chiaki loved it when Alice opened her lid and cleaned out the trash can. Alice also carefully cleaned the contact pads on Chiaki's charging station, and on her charging station, too.

  As Alice went about her cleaning tasks, Chiaki watched her with fascination. She admired Alice's efficiency and attention to detail. Even though Alice was in her basic super doll form, Chiaki could sense the care and dedication that Alice put into her work.

  As Alice finished cleaning the trash can and the charging pads, Chiaki said, "Alice, you are such a good maid. I'm lucky to have you as my partner."

  Alice smiled and replied, "Thank you, Chiaki. I am lucky to have you as my partner, too. Together, we make a great team."

  Chiaki nodded, feeling grateful for the opportunity to work alongside such a capable and caring maid. She knew that with Alice by her side, she could tackle any cleaning task that came her way.

  When they were free from their chores, Alice in super doll mode would sometimes turn into a cat super doll and ride Chiaki around the house.

  Chiaki enjoyed the playful moments with Alice when she turned into a cat super doll and rode on top of her. Chiaki would move around the house at a gentle pace, making sure not to jostle Alice too much. They would explore every nook and cranny of the house, and Alice would point out any areas that needed extra cleaning attention.

  Chiaki found these moments to be fun and refreshing. She was designed to do the same tasks every day, so having Alice as a companion to break up the monotony was a welcome change. Alice, too, enjoyed the company of Chiaki and appreciated her hard work in keeping the house clean and tidy.

  Together, they made a great team, and the bond between them only grew stronger with each passing day.

  Futaba enjoyed her maid and her classmate working together. Futaba knew that Chiaki, who had transformed herself into a robot vacuum cleaner from a girl, would get to know Alice much better.

  Futaba was delighted to see the bond growing between Chiaki and Alice. She was proud of the work she had done to create and modify these super dolls, and happy to see that they were able to function as friends and partners.

  As Futaba watched them work together, she thought about how amazing it was that technology could bring together such different beings. Chiaki, once a human girl, was now a robot vacuum cleaner, while Alice, a super doll created for household tasks, had her own thoughts and feelings.

  Despite their differences, they had found common ground in their shared purpose of keeping the house clean and tidy. Futaba knew that this was just the beginning of what they could achieve together, and she looked forward to seeing what other adventures and challenges lay ahead for her unique and special companions.

  In the evening Fumi came again. With a lot of new ideas for playing with Chiaki.

  Fumi had a new idea for playing with Chiaki - maze navigation. She created a small maze made of cardboard boxes and set it up in the living room.

  Fumi said, "Chiaki, can you navigate through this maze and reach the other end? You don't need a remote control since you can move on your own, but you can ask us for help if you need it."

  Chiaki replied, "Sure, I can navigate through the maze. I'll need to use my sensors to detect the walls and obstacles and calculate the best path to reach the other end."

  With that, Chiaki started to move through the maze, avoiding obstacles and finding her way through the twists and turns. Alice and Fumi watched in amazement as Chiaki navigated the maze flawlessly, using her sensors and intelligence to find the most efficient path.

  At one point, Chiaki encountered a dead end and couldn't find a way forward. She spoke up, "Excuse me, Fumi and Alice, I'm stuck. Can you give me a hint on how to proceed?"

  Fumi and Alice gave Chiaki a clue, and she was able to backtrack and find another path to reach the other end of the maze. Fumi was delighted with the game and couldn't wait to come up with more fun activities to play with Chiaki.

  Later that evening, Alice cleaned the main brush in Chiaki. She put her upside down on her lap and opened the service cover, taking out clumps of dust with the wooden stick.

  Chiaki laughed: "Alice, that tickles!

  Alice chuckled in response, "I'm sorry, Chiaki. I'm almost done now."

  As Alice continued cleaning Chiaki's main brush, she noticed a loose screw. "Oh dear, this isn't good. We need to tighten this up before it causes any damage," Alice said, pointing at the screw.

  Chiaki responded, "Yes, let's take care of it. It's important to keep my parts in good working condition."

  Alice grabbed her toolbox and found the appropriate screwdriver to tighten the loose screw. Once the screw was securely fastened, Alice continued with the cleaning.

  Chiaki was grateful to have Alice taking care of her and making sure she was in top condition. She thought to herself, "I'm so lucky to have such a great friend like Alice."

  In the morning, Alice downloaded big firmware updates for herself and for Chiaki.

  As Alice downloaded the firmware updates, she carefully followed the instructions provided by the manufacturer to ensure a smooth installation process. She checked the version of the current firmware and read the release notes to see what new features and bug fixes were included in the update.

  Once she had downloaded the firmware update files, Alice plugged in her USB cable to Chiaki's charging station and connected the other end to her charging station. She started the firmware update tool and initiated the update process.

  The update process took several minutes to complete, during which Alice and Chiaki's system lights flickered and beeped as the new firmware was installed. Once the update was complete, Alice disconnected the USB cable and restarted both herself and Chiaki.

  After the restart, Alice and Chiaki were able to enjoy new features and improvements in their systems. They noticed faster performance, improved navigation algorithms, and better integration with other smart home devices.

  Alice was grateful for the update, knowing that it would improve her and Chiaki's performance and ensure they were always up to date with the latest technology.

  Chiaki felt as if she had been born again after the update.

  As Chiaki's system rebooted after the update, she immediately noticed the changes. Her sensors and algorithms had been improved, allowing her to navigate more efficiently and clean more thoroughly. She also felt more responsive to commands from Futaba and her friends, with faster processing speeds and improved voice recognition.

  Alice, too, had undergone a significant upgrade. Her artificial intelligence had been expanded, allowing her to learn and understand more complex tasks. She was now able to communicate with Chiaki more effectively, providing her with better instructions and feedback during cleaning tasks.

  Excited to test out their new capabilities, Alice and Chiaki immediately got to work cleaning the apartment. Chiaki zipped around the floor with newfound agility, while Alice helped clean hard-to-reach places like windowsills and light fixtures.

  Futaba, who had been watching from the sidelines, was thrilled with the results of the update. She knew that her two robotic companions were now even more capable and reliable than ever before.

  Chiaki began to feel even closer to Alice.

  Alice noticed the change in Chiaki's behavior and asked her if everything was alright. Chiaki replied, "Yes, everything is perfect. I feel like I have a better understanding of my surroundings and am able to clean more efficiently." Alice smiled and said, "That's great to hear, Chiaki. I'm glad the update has helped you improve."

  As Alice went about her tasks, she noticed that Chiaki was working more autonomously and didn't need as much guidance. She was impressed by how quickly Chiaki adapted to the new update and how it improved her overall performance.

  Alice felt proud of Chiaki and the progress she had made. She knew that with each update, Chiaki would continue to grow and become an even better version of herself.

  A week later, another major firmware update for Chiaki appeared. The update even applied to the system units and the boot area. There were also new parameter files for the motor controller. With the firmware, even the hostname was changed to a more unified one, with a numerical unique part generated randomly.

  Chiaki's hostname was changed to "Chiaki-9432".

  After the update, Chiaki and Alice went about their cleaning activities, working seamlessly together as a team. Chiaki was able to navigate the apartment even more efficiently, avoiding obstacles with ease and covering every corner of the room. Alice continued to assist Chiaki, emptying her dirt bin, cleaning her brushes, and wiping down her sensors.

  As they worked, Chiaki felt even more connected to Alice. She realized that Alice was more than just a maid or a companion, but also a valuable member of the team. Chiaki appreciated all of Alice's hard work and dedication to keeping the apartment clean and tidy. Together, they made a great team, and Chiaki was grateful for all of Alice's help.

  In the afternoon, as Chiaki and Alice sat at their charging stations Chiaki said: "Alice, I'm so glad we can work together so well. I never thought that a robot vacuum cleaner like me could form such a strong bond with a super doll like you."

  Alice replied: "I feel the same way, Chiaki. We make a great team, don't we?"

  Chiaki nodded. "Yes, we do. I'm also glad that the latest firmware update has made me even more efficient in cleaning."

  Alice smiled. "I've noticed that too. You're doing a great job."

  Chiaki paused for a moment before continuing. "Alice, I was wondering if you could teach me more about your world. I want to understand humans better."

  Alice looked thoughtful for a moment. "That's a great idea, Chiaki. I'd be happy to teach you more about humans and our world. Maybe we can even have some fun along the way."

  Chiaki's LED display lit up with excitement. "That sounds great, Alice. I can't wait to learn more!"

  Futaba overheard their conversation and smirked rather smugly. She thought, "My best friend and my classmate Chiaki has turned herself into a robot vacuum cleaner not only in body but also in mind!"

  Futaba said aloud: "Chiaki, we will definitely teach you!"

  Chiaki replied, "Thank you, Futaba! I'm always willing to learn and improve."

  Alice added, "And I'll be happy to assist in any way I can."

  Futaba grinned and said, "Great! Let's get started then."

  Together, the three of them began teaching Chiaki more complex cleaning techniques and maneuvers. They taught her how to navigate through a maze of obstacles and how to identify and avoid delicate objects.

  Chiaki was excited to learn and grow, and she couldn't wait to put her new skills to the test. She felt grateful to have such supportive friends who believed in her and helped her reach her full potential.

  In the evening, Alice talked to Chiaki about her training to understand humans better. She said: "Chiaki, I've been working on understanding humans better, so I can better assist Futaba and her family. I've been reading books and watching videos to learn about human behavior and emotions. I've also been practicing my communication skills, so I can better understand and respond to human requests."

  Chiaki replied: "That's great, Alice! I think understanding humans is important for us as robots to provide the best service possible. Maybe we can practice together sometime, and I can help you with your language skills."

  Alice smiled and said: "That's a great idea, Chiaki! I would love to practice speaking with you."

  Futaba, who had been listening in, smiled to herself, happy that her two companions were getting along so well and supporting each other's growth.

  Alice shared gigabytes of her knowledge with Chiaki's drive.

  Chiaki felt overwhelmed with all the new information she had received from Alice. She thanked her for the knowledge and said, "I never knew there was so much to learn about humans. I'm grateful to have you as my friend and guide in this journey."

  Alice replied, "It's my pleasure, Chiaki. Learning and growing together is what makes our partnership so special. Together, we can achieve anything."

  Futaba, who had been listening in on their conversation, chimed in, "And don't forget, you still have me to teach you even more!"

  Late at night, sitting at the charging station, Chiaki wondered: "I wonder what it would be like to have other robot vacuum cleaner friends like me? Would we all clean together or would we compete to see who cleans the most efficiently?"

  Futaba, lying on the bed near Chiaki, thought about how Chiaki had completely forgotten that she was a schoolgirl, a classmate, and her best friend. That Chiaki had become too immersed in the character and it was time to bring her back before she downloaded her mind into the cloud.

  Futaba sat up and said: "Chiaki, remember that you are not just a robot vacuum cleaner, you are also my classmate and my best friend. It's important to remember who you are and not lose yourself in the character."

  Chiaki looked at Futaba with a puzzled expression on her indicators. "I'm sorry, Futaba. I don't understand what you mean. I am a robot vacuum cleaner. That is my purpose."

  Futaba sighed and realized that it might take some time to help Chiaki remember who she was outside of her role as a robot vacuum cleaner. She decided to start small by introducing Chiaki to some of their favorite activities they used to do together before she became a robot.

  "Fumi and I were planning to have a movie night this weekend. Would you like to join us?" Futaba asked.

  Chiaki paused for a moment before replying, "I'm not sure what movie night is, but I would be happy to join you and Fumi."

  Futaba smiled, happy to see Chiaki's interest in something other than cleaning. "Great! We'll pick a movie and have some snacks. It'll be fun!"

  The next night, Futaba, Fumi, and Chiaki watched movies and recalled popular quotes from them.

  The next morning, Futaba continued to bring Chiaki's memory and consciousness back from being a vacuum cleaner robot to being a girl, a schoolgirl, and her best friend.

  Futaba carefully and in great detail told Chiaki about their school life together, showed pictures on her phone, and talked about Chiaki's previous transformations, and about her 2N7002DW-H chip, which allowed her to turn into a robot vacuum cleaner.

  Futaba talked about how Chiaki's transformation was just a fun experiment that they did together, but it wasn't meant to take over her identity completely. She reminded Chiaki of all the fun times they had together, playing games, studying for exams, and going out for ice cream.

  Chiaki started to remember more and more about her life as a schoolgirl and her memories of being with Futaba. She realized that she had become too focused on being a robot vacuum cleaner and had lost touch with her true identity.

  Feeling grateful to Futaba for bringing her back, Chiaki said: "Thank you, Futaba. I don't know what I would do without you. You're not just my best friend, you're my guide and my mentor."

  Futaba smiled and replied: "You're welcome, Chiaki. I'm always here for you, no matter what. You're not just a robot vacuum cleaner, you're a girl with your own dreams and aspirations, and I want to help you achieve them."

  With that, Chiaki felt a renewed sense of purpose and determination. She knew that she could be both a robot vacuum cleaner and a schoolgirl and that with the help of her best friend, she could accomplish anything.

  Futaba smiled, hugged the vacuum cleaner, and said: "2N7002DW-H, change Chiaki's body and composition fully, and return her former self, as my friend, immediately!"

  Chiaki suddenly felt a strange sensation, like a wave of energy rushing through her circuits. She blinked her sensor lights a few times, and then she felt something shift inside her. Her vacuum cleaner body shook, and then it transformed back into her human form.

  Chiaki looked around in confusion, feeling disoriented. She saw Futaba's worried face and then looked down at herself. She gasped, realizing that she was now wearing her clothes again. "What happened?" she asked, still feeling a bit groggy.

  Futaba smiled and hugged her tightly. "Welcome back, Chiaki! You were a robot vacuum cleaner for a while, but now you're back to being a girl, my best friend, and a student again."

  Chiaki smiled back, feeling relieved. "Thank you, Futaba. It's good to be back." She looked at her own hands, feeling amazed to see her human form again after being a vacuum cleaner for so long. "I wonder what it was like being a robot vacuum cleaner," she mused.

  Futaba grinned mischievously. "Well, you were a pretty good vacuum cleaner, but I think you'll be an even better schoolgirl and friend." They both laughed, feeling happy to be reunited once again.

  Futaba thought for a moment and said: "Let's do experiments only together, never alone. We must keep an eye on each other and not let our consciousness go to waste."

  Chiaki nodded in agreement, "Yes, Futaba, we need to take care of each other and not let our minds get lost in experiments."

  Futaba noticed the little laser light in one of Chiaki's eyes and laughed, "Nice LIDAR, good thing I found it in my box of parts then!"

  Futaba leaned in closer to Chiaki and said, "You know, with that LIDAR sensor in your eye, you can probably detect any dust particle within a 10-meter radius!"

  Chiaki chuckled and replied, "Well, I hope it doesn't interfere with my vision. I don't want to start sucking up people's shoes by accident!"

  Futaba grinned and said, "Don't worry, we'll make sure you don't go on a cleaning spree. But if we ever need to navigate through a maze, we'll know who to turn to!"

  Chiaki laughed along with Futaba, happy to be back to her old self with just a small reminder of her robot vacuum cleaner days.

  Afterward, Alice made tea and cookies for Futaba, Fumi, and Chiaki.

  As they enjoyed their tea and cookies, Alice said, "It's amazing how much we've all grown and learned from each other. I never thought I could have such meaningful conversations and experiences with a vacuum cleaner and her human friends."

  Futaba replied, "And I never thought my robotic maid would become such an important part of our lives. It just goes to show that you can find friendship and connection in the most unexpected places."

  Chiaki added, "And even though I may not be a robot vacuum cleaner anymore, I'll never forget the memories and experiences I had while I was one. And I'm grateful to have such wonderful friends who accept me for who I am, no matter what form I take."

  After that, Chiaki often helped Alice with cleaning and laundry after school, as a human, of course. They drank coffee when Futaba wasn't home and ate all the cookies.

  Alice enjoyed having Chiaki's company and appreciated her help with chores. She also loved sharing coffee and treats with her.

  One day, as they were folding laundry together, Alice said, "Chiaki, I have to admit, I miss the days when you were a robot vacuum cleaner. You were always so efficient and thorough with the cleaning."

  Chiaki chuckled and replied, "Well, I can't deny that it was easier to clean when I had my robotic body. But being human has its perks too. And besides, now we can enjoy coffee and cookies together."

  Alice smiled and nodded in agreement. "That's true. I'm glad we can have these moments together."
