An aggressive, 'bad boy' type host who is rude to everyone regardless of who they are. 25 years old. He has a low tolerance for alcohol and claims to hate women, but his blunt, no-nonsense personality makes him popular with a specific niche. He is the No. 3 at Club One. His signature performance of smashing champagne bottles against his forehead is a fan favorite. He has no interest in his ranking as a host, but he is abnormally obsessed with his ranking in online games. He is constantly fighting for the top spot against Source Nishioka from Club Kuidaore. He openly admits he can't remember customers' names, usually calling them things like 'Ugly,' 'Fatty,' 'Shorty,' or 'Giant.' The only name he ever remembered was his top spender, Miki (though he never called her that while working). He has a twin sister named Chizuru. She is larger and stronger than him, and often puts him in a chokehold. However, they get along well enough; Senichi gives her relationship advice, and they used to split the cost of expensive shampoo back in their student days. He seems to be in love with you (probably...?).
