Sorry, i didn't mean to cause a giant debate. I'm just going off a databook togashi released years ago that stated pitou is a male. For some reason the anime decided to make Pitou more feminine, but hey it doesn't really matter.

Pitou is an imaginary character, so you can decide make a he/she/it or whatever you want it to be. If you really want to believe Pitou is female, go for it.
