- Kou's room is strikingly traditional. The features of his living space emphasise balance, harmony, economy and beauty and seem to lack any kind of warmth. There are sliding doors made from wood and paper, which are portable and easily removed. Shelves of books and other things are hidden behind these partitions. The paper is thin enough that an outside light illuminates the room in the daytime. The colours are understated, with a splash of dark blues and greens. On the outside balcony there are wooden floored passages that serve as a hallway, with a distant view of the City.
- His few personal possessions to have arrived are a traditional Japanese teaset and various hanging scrolls. Also his poetry diary that keeps vanishing from his room.
- He's most often in his room, and occasionally in the kitchen.
- Kou still finds it difficult to talk under pressure, under which he'll clam up and just go back to his room. He is the sort of flatmate who keeps to himself and prefers peace and quiet, so he might politely ask people to about any loud noise. He tries not to get involved in arguments and will tell those involved they must solve their own problems and act like adults. He prefers not to bring people back to his room, viewing it as a private sanctuary. He prefers non-televised entertainment and can be found near the kotatsu reading, though he will occasionally glance at the television.
