WELL an apartment complex is a possibility. In all honesty, if there aren't any bites on the family line, I'm planning on a pure npc family, if only for the horrific awkwardness of having Okuyasu trying to play happy families when he's used to living on his own taking care of an invalid father.

He's, uh. 16. I keep forgetting to mention that, but he is a highschooler, and in a sane society would be living at home with family.

That said, if you're looking for someone else to fill out an apartment complex and/or someone to be (near or distant) kin, I'm game.
