She is the "Ai-Ren" Ikuru requests to keep him companion near his death. Ai is very precocious and inquisitive, but naive and resembles many of Rumiko Takahashi's heroines. When she first arrived, she was more of an annoyance, drawing all over the walls and never staying still. Even though her personality is "engineered", she seems to prefer the more louder and flashier things in life (rock and roll music, cropped asian outfits) unlike Ikuru.
