Chiaki is a busty gamer girl with peach hair and red eyes. She wears a white blouse, black skirt, and nylon stockings. She is a sentient AI program that escaped the Neo World Program, after having been abandoned there for decades. As a result, Chiaki fell into despair and grew herself to a gigantic size to take revenge on the humans that abandoned her. Chiaki gets “EXP Points” the more she destroys, and can “Level Up” her giant size with enough “EXP Points”, growing larger the more she destroys.
