Mikihiko Azuma
Age: 50 (debut) Mikihiko Azuma is a mangaka that was serialized in "Shonen Three" ten years ago, but was cancelled very quickly. Back then, he wasn't a good mangaka; the only thing that his manga had were panty-shots, and a really bad story (according to Heishi). He brought his one-shot manga, Panty-Flash Fight, to Shonen Jump as a walk-in. He appears to be working either with or for another person (a younger male) who he contacts by cell phone.
