Misa Aoi is the younger sister of Risa Aoi whose initial indifferent disposition is challenged when she comes into contact with Rin Namiki. She is described as not particularly talkative at first, she has no problem with entering a room with a do not enter sign and taking part in a Kandagawa simulation by herself. Misa expresses frustration when the simulated environment begins to flicker and kicks the machine in frustration.
