Saki Achiga Hen episode of Side-A Portable

The Achiga Girls' Academy in Nara once defeated regional mahjong powerhouse Bansei High School. It advanced into the national team semifinals but lost to the eventual champion, and the mahjong club was later disbanded.

Six years later, elementary school student Takakamo Shizuno befriends transfer student Haramura Nodoka. The two eventually enter Achiga Girls', but Nodoka transfers out of the school in the second year.

When Shizuno sees Nodoka on television the following year as the national middle school individual mahjong champion, she decides to revive Achiga's mahjong club.
