Golden Sakura

Golden Sakura follows Takuya Saotome, a skilled but low-earning and nearly unknown mahjong player, whose girlfriend tricks him into taking on five million yen in debt. He does not know how he will be able to repay the money, but Nabe, a friend running a gay bar, suggests a plan to earn money by becoming a female professional mahjong player. Desperate, Takuya agrees to it and retakes the professional mahjong player examination while cross-dressing as his new female persona Sakura Shindou, and has to continue playing both as himself and as Sakura.
