Can someone explain the fixation the japanese artists have with weirding Muska out? I thought this was a masao-only thing, but Matataku has done it before, too.
Maybe it's sort of like that thing of having serious characters doing ridiculous stuff because it's funny. Like having a prim-and-proper gentleman with a monocle shoot lasers out of his eyes while drinking tea.
I'm pretty sure it has a trope name but I can't think of it.
