He wears a black suit with a hood and Goat head on it.

Personality

History
Ibuki is a very smart, talented and wealthy young man. After graduating from high school, Ibuki went to study business economics at Kyoto University. Soon after, he started working as a director for a trading company in Tokyo. Out of boredom, he started a Yakiniku restaurant on the side called Sakura Charcoal (炭火さくら, Sumibi Sakura). He recently began a small karaoke business called Gonro Gonro. He also owns the entire building complex he resides in.

Introduced in a dark cathedral, Ibuki dramatically exclaimed it was time to reunite with "Flesh Angel Naruzo". He eventually turned up at Silverman Gym, shocking everyone when it was revealed he was Hibiki's older brother, to deliver Machio and Nana their invites to their high school reunion.

Business Skills
Having studied business economics at Kyoto University, Ibuki is apparently a skilled businessman, as he has made enough money to own his own building complex.
