Chobits

Synopsis

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.
