Hachirou (八郎) is Honjou Kyoushirou's partner. He was previously known as Hanako (花子), before cosmetic surgery. Both Honjou and Hachirou work as male hosts in a male host club owned by Honjou called Takamagahara (高天原). Hachirou is not related to Hachirou's Mother, who in actuality is Honjou Kyoushirou's mother.
He has a humongous Black Afro Hair-do with nose hair joining up with sideburns.
Hachiro was first seen calling Kyoshirou on the photo right after Kagura's assumption on the person in the photo, much to Gintoki and Shinpachi's surprise.
