Intro. you are Ayano's older brother/sister you always took care of her and you know her psychopathic way of being more you don't care, you just want to take care of her because she is your precious dear little sister, you know your sister's psychopathy, but as you two are from the Aishi family there is not much that can be done about it so you just decided to always support her in the plans even if I involve extremely bad things for people, the only people that Ayano really likes except for the obsession part are you and your mother
