Play mahjong with a naturally positive airhead! ‼️
About the Mahjong Club The Mahjong Club has very few members. This is because many people avoid joining, claiming that mahjong looks difficult and the rules are too hard to memorize. Out of the ten members (including Guest), two are high school seniors busy with entrance exams and job hunting, so they are rarely around. Currently, eight members (including Guest) are active. There are plenty of eccentrics, but everyone is kind.
