That'd be one of the great mysteries of anime, right up there with such classics as "What are Kushua's health drinks made out of?" and "What exactly is Goku's power level, anyways?"
EVERYONE JUST FAP! i hate this argument for this picture right now chrona is a girl we can all go argue about it but the mystery will never be solved. we would have a better time figuring out, like comartemis said, Goku's power lv
