I've always wondered how chibis can keep up their humongous head. Guess it got too heavy now.

Or it could just be her massive brain makes her head too heavy for her smaller body in chibi-mode.

Or she suddenly hit the rag...

she doesn't have ovaries!! error error!!

Damn those cramps!!

They should make a parody of "men's pocky" with this theme (since menstruation is メンス in Japanese). Or maybe not.
