ちぃ 弱る Chii Yowaru Chi Weakens

Hideki begins to worry because Chi seems to be tired constantly. He talks to Shinbo about this, and learns that Persocoms need to be charged. Normally, prolonged exposure to sunlight is fine, but in this case, Chi needs to be plugged in. When Hideki returns, he finds that Chi is very close to losing all of her battery power, but he cannot recharge her because he hasn’t paid his electricity bill. In a desperate attempt, he tries to take Chi to Yorokonde but gets horribly lost along the way.

Hideki is facing his first practice exam and goes to the book store to buy an English dictionary since he forgot his own at his parents’ place. At the store, Chi finds a picture book called “A City with No People,” which sparks Chi’s curiosity. Hideki buys it for her rather than his dictionary, and Shinbo lends his to Hideki. While Shinbo is teaching Hideki how to use the dictionary, Chi finishes the picture book and something unusual happens.

After several mishaps and mistakes, Hideki finally plucks up the courage to run into the store and buy them himself and run back out.

Chi begins learning words from Hideki, who is running very low on money. He decides to get a job to pay for his living expenses.

Hideki wants to find out more about Chi, so he takes her to Shinbo’s friend Minoru Kokubunji, who is a rich but very young expert on Persocoms. There, they find out she has some sort of learning program even though she has no OS (Operating System). Minoru concludes that Hideki is able to teach her and that she will be able to grasp information that she is given. While leaving the house, Minoru tells Hideki not to fall in love with her if he do not want to cry later. Later, at his room Hideki gives name to her “chi”.

Hideki Motosuwa is an 18-year-old student living with the short end of the stick. He’s short of money, has to go to prep school, and is still a virgin. Hideki dreams of getting into college and having a cute Persocom to surf the internet for pornography. While he’s out one night, he finds a Persocom in the garbage, activates her, and names her Chi, after her first word, which appears to be the only thing she can say. After trying to hide her from Hiromu Shinbo, his neighbor (and his mini-Persocom Sumomo), and trying and failing to hide her from his landlady, Ms. Hibiya, he decides to keep her, much to her joy.
