Arata Sagimori

As the central figure of the "Saki: Achiga-hen episode of side-A" spin-off, this second-year student at Achiga Girls' Academy brings a steadying presence to her team. A childhood friend of Kuro and Yuu Matsumi, she grew up around mahjong at her family's local bowling alley before a long hiatus. Driven by her admiration for Harue Akado, she rejoined the game to revitalize the school's mahjong club, eventually being appointed president due to her remarkably composed and level-headed nature.
