He's one of the Ten Patch Priests—basically the elite council overseeing Shaman King stuff. His specific gig is managing three teams: Hana-Gumi, Hoshi-Gumi, and the Magical Princesses, which means he's the Patch Officiant calling the shots for their matches.
What really defines him, though, is that he's openly Team Hao. While most of the Patch Priests play it neutral, he doesn't hide his support for Asakura Hao's bid to become the next Shaman King. It's a pretty bold stance to take, especially when you're supposed to be impartial.
