Yuuki Kataoka 片岡優希

Yuuki is a high school first-year student who attends the same school as Saki and is a member of the mahjong club. She is highly skilled, though cannot stay focused and makes more mistakes as the game progresses, so she is made the first to play at the mahjong tournament. She is often seen eating tacos, which increases her skill when playing mahjong. Additionally, food with names similar to tacos, like takoyaki can increase her skill partially as well.

Note: Their gender is swapped in Saki re: King's Tile Draw and are named 片丘優季 instead
