Otome Chono

She is one of Tetsuro's roommates. She is also part of the group "Koi Koi 7". She has a very calm personality which makes her less aggressive than the other girls in the group. In the anime she has been seen "charging up" using a plug during breakfast, also in the group she is the person who gives the orders and information to the rest of the group after analyzing the data. This implying that she could be a robot or something that is not human. Through the first few episodes you may see Otome commenting "incomprehensible", making her even more "robot-like.
