Summary
Yuu Matsumi serves as a central protagonist in the spin-off manga Saki Achiga-hen episode of side-A. She attends Achiga Girls' Academy in Nara Prefecture as a third-year high school student and is the older sister of Kuro Matsumi. During her youth, Yuu harbored a desire to join the mahjong club alongside her peers but hesitated due to concerns that her seniority would make the situation awkward.
