That aside, the way that thing that keeps defenestrating him looks has been bugging me--I now know what it reminds me of: it looks like a monstrous teru teru bouzu. And it makes sense: he himself said that he's called "The Sun" by others, and his name is in fact close to "taiyou" (lit., "sun") backwards. That TTB is actually a prayer for the "sun", Youta, to come out. Whose prayer that TTB is, though, is something I don't know.
