Four years before Nodoka Haramura joined Kiyosumi High School she lived in a small town near Achiga Girls Academy. There she became friends with Shizuno Takakamo, Ako Atarashi, and Kuro Matsumi all members of a Mahjong club for beginners ran by Harue Akado. The club however was disbanded when Harue was scouted by a professional Mahjong team, this lead to the group spliting off and going their own ways.
Three years later, Shizuno saw Nodoka win the individual middle school mahjong championship and decided to start the Achiga Girls Academy Mahjong club back up again.
