I just don't get it, what the problem in living in room full of blood? Nobody ever mentioned any gross smell, so where's the problem? It even was going to be cleaned soon.
WTF, I have been watching Higurashi no Naku Koroni past few hours and needed something light and funny to change the mood, so I thought I'd watch some Gintama, and this is the episode I start with... just WTH really...
