Kill Joe has a ghost ability that he can create certain inlusions and change people shape whenever he like.
He is using this ability to transform his present self Haru in a woman when they both were in a public poll.
This is a funny situation for sure. (Also, like KJ is a ghost, few people can see him).

This is a little escuse because is been a time that I don't draw females so here somethin different. I hope you guys like!!
Also Kill Joe can transform anyone in anything, is a kind special of possesion. ;)

PS: Haru is the only that Kill Joe consider as a friend (canon)
