It couldn't be helped, Hakuba has been spending a lot of time around Maraich lately (although Maraich usually goes for much older men, so this doesn't necessarily mean he's looking).

Maraich is 18-19-ish. He's 18 during the entire manga, and it feels weird making him older than that.
He was born in 1965, though, and I'm making DDD!canon 1984.
