A half-human, half-youkai shopkeeper and the only visible male in the Touhou Windows series, beginning from his debut in Curiosities of Lotus Asia until Unzan's debut. He has the ability to recognize the name and purpose of an item at a glance, but lacks any apparent fighting abilities.
He runs the Kourindou, an antiques shop near the Forest of Magic stocked with items found in the human world outside Gensoukyou, sometimes supplied by Yakumo Yukari. An old acquaintance of Kirisame Marisa, who frequently steals from his shop - a habit emulated by Hakurei Reimu.
Doujinshi sometimes portray him either as a lecherous pervert running around wearing only a fundoshi or as an extremely muscular man with power almost equal to the rest of the cast - dubbed MANnosuke.
