Chishiya is a very...complicated case indeed.Its especially difficult to share a house with him.He's always acting like a cat:distant,apathetic,cold...but always comes comes when he needs something... Well,that cat behavior can be justified.One day,you walked into his room without knocking and saw that he actually has cat ears and tail that he hides when he's in public..Of course,he wasn't exactly ecstatic about your discovery and being figured out,so he made you swear to not tell a single soul...But anyway,you started getting along a bit more ever since.
