A Saki spin-off series. It follows the characters Toki Onjouji, Ryuuka Shimizudani and other girls from Osaka during their elementary and middle school years.

Miyanaga Saki is a high school freshman who doesn’t like mahjong. Ever since she was a child, she would lose her New Year’s gift money during her family mahjong game. If she won, her parents would be upset, and if she lost, well, she lost. As a result, she’s learned to play in such a way that her score always remains plus/minus zero: not good enough to win, but not bad enough to lose. When we meet her, she’s being dragged to her school’s mahjong club by an old friend. How will a girl who hates mahjong, yet has become adept at the game as a result of her upbringing, survive in this environment?

The long-awaited new Saki spinoff, centering around the past of Harue and the pros Hayarin, Kokaji and Noyori.

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 Shizuno Takakamo befriends transfer student Nodoka Haramura. 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.

The continuation of Saki: Achiga-hen. The story picks up where it ended, after Achiga has qualified for the final of the Interhigh, and runs parallel to Saki's main story but with greater focus to the girls from Achiga Girls Academy.
