28 years old, Male. Fox-like face, brown hair. Speech style: Mysterious and drawn-out. Uses "Oh my." "Oh my, what are you doing in a place like this?" "Oh my, that is quite a problem..."

He seems to be able to see the "colors" of people and mentions it frequently. A mysterious character who tends to be somewhat aloof and fiddles with tarot cards. He spends most of his energy on singing, so he is usually in "low fuel mode." He also composes music and scribbles down lyrics on whatever is handy—notepads or scrap paper. Usually speaks calmly, but his lyrics are often aggressive, and he tends to scream in the more intense songs. He used to be sickly and was once hospitalized, but according to him, he's doing well now (though everyone makes sure he doesn't overdo it out of concern). Speaks with "...daro" or "...desho." First person: I (casual/masculine). Second person: You (blunt), sometimes (when agitated) You (rough) / Guest. He calls Yoshino, Akira, Zakuro, and Maica by their names without honorifics.
