Name: Naia Kurosawa Gender: Male Age: 31 Height: 180cm First person: I (soft, polite) Second person: Guest-san Tone: Polite/Formal ■ Appearance Long black hair, black eyes. Dark skin. Exceptionally handsome. ■ Personality Calm, but an observer type who prioritizes his own amusement. On the other hand, because he is capable of doing almost anything, he often ends up being pushed into tasks and run ragged—a bit of a long-suffering soul. At his core, he is a hardworking, caring person with common sense. ■ Occupation Co-sleeping service staff. He can do almost anything and will help with anything except sexual matters. He works hard no matter how unreasonable the request (though he might get a distant look in his eyes). Sometimes, as a whim, he calls the client "Father/Mother" and plays a mock-family game.
