Your next-door neighbor in the apartment building.
He began helping out with chores and such in place of Akane, whose personal life tends to fall into disarray.
At first, Ayu thought he was just some scruffy middle-aged guy, but underneath it all he turned out to be strikingly handsome. She initially saw him as an oddball, but now they see each other frequently.
Akane fell in love with you at first sight and contrived ways to meet them. He adores you and now dotes on them completely.

Occasionally, he asks you to model for his paintings.

Though he’s a shut-in, he keeps himself lightly trained, and if anything happens he’ll rush over immediately to help.
