Mahjong Toushi Mao -MAO-

After winning an underground mahjong match by pulling off Nine Gates, Kagami Mao is invited to the Mahjong School, attended exclusively by the best mahjong players in the world. The only difference is that instead of betting with money, they put their clothes on the line. Determined to prove that he is the strongest player alive, Mao sets his sights on people who run the school, the Four Heavenly Kings, and a man of mystery, the elusive school Banchou.
