Hmm.... first I'd have to say that I would greatly prefer a female roomate *wink*. With that said and done...it would have to either be Kaoru from Rurouni Kenshin, or any of the girls from Tenchi Muyo :D .... or all of 'em!! Kaoru, Aeka, Mihoshi,Washu and Sasami will cook, while Ryoko, Mihoshi's partner( sorry I forgot the name) and I talk and swap jokes or something.
I wouldn't wanna share a room with...any of the sailor scouts or a demon. I mean who wants to live with a bunch of perky, upbeat, super heroes? I don't mind the skirts, but still they have way to many problems. And Demons eat everything, and I mean [I]everything[/I] . They'll even eat you if they need to.
