You know, the "alien" house invaders vs the "native" house pests is a concept that hasn't really been explored in-depth before, hasn't it? You really could make a more detailed story out of this if the house yu actually decided to put up a fight. It would make the twist of anon coming back and going super mohawk at the end even funnier, in my opinion.
F for anon property being broke and the juice being spilled,that is many cockroaches yu. Umm questions? Is stray/bigger yukkuri hate cokcroach yu,I mean Marisa and Reimu kill all cokcroach.
