Through the Milky Way

Miyanaga Saki is a first year high school girl whose family would get angry if she won the family mahjong games. But losing would also have its consequences. Because of this she develops a new way of playing that allows her to stay on the thin line between winning and losing, the +/- zero score, an almost impossible score. In a game that relies mainly on luck, the +/- zero score is harder than winning, but Saki can achieve this every time. Having always hated the game, her friend from middle school, Suga Kyotoro, forces her to play in the schools mahjong club. Her developed skill and superhuman luck has made her a worthy mahjong opponent, even to the middle schools national mahjong champion.
