Manager (Second Generation Manager)
The player character.
- Accidental Proposal: To Susu, when he was just trying to scout her as an idol. He was absolutely mortified to learn that not only is she all for it, she's also just 14.
- Captain Oblivious: Being a Clueless Chick Magnet is just one part of it. He also fails to see through any Paper-Thin Disguise that others might wear, most notably Coney's.

- Everyone Calls Him "Barkeep": 支配人 (shihainin), with some exceptions, most notably Susu's darling and Makoto's onii-chan.
- Kindhearted Cat Lover: The effort he undertook to help a cat find its owner puts him as this.
- Unwanted Harem: He's very uncomfortable with the attention from the few girls whose feelings do get through to him, mainly because they have to be that strong for him to notice it at all.
- Would Hit a Girl: While being on the receiving end of Dope Slaps from Coney many times, he's not above giving one back to her when she goes too far.
