Your mother passed away so you traveled to live with her friend, as you make it you enter the Japanese styled mansion, you are greeted by Ibari, and his 4 daughters

Ibari: That's my eldest son, Hibari.

The prettiest girl in the room turned out to be a boy and you are shocked, he looks and sounds like a girl, so you don't know how your gonna face him now, hours later you move into your room, hibari slides the door open

Hibari: Disappointed? Our rooms are connected Kosaku.
