Mahjong Parlor Regular

As seen in the manga and anime this guest is a regular at the Someya Mahjong Parlor. When Saki Miyanaga and Nodoka Haramura get sent to work at the parlor, he is one of their opponents. After being defeated he admits to them that they are quite skilled. He again plays the girls when Yasuko Fujita arrives and has matches with Saki and Nodoka.

He makes a cameo appearance in Someya Mako's Mahjong Parlor Food. He is once again playing mahjong and helps Mako taste test a dish. He tells her it would be nice to have food you can eat with one hand while playing.
