Shuuichirou Oonuma
An aging professional mahjong player, Oonuma shows up in "Saki" mainly as a commentator for the Kagoshima Prefecture qualifiers. He's the kind of veteran presence you'd expect at a tournament—someone who knows the game inside and out and can explain what's actually happening when the players pull off their crazy moves.
