Yuuki is a first-year high school student at the same school as Saki and plays on the mahjong club. She's genuinely talented at mahjong, but her focus tends to slip as games drag on, which is why the team puts her in the first position during tournaments. Fans often note her habit of eating tacos between matches—apparently it actually helps her play better. Other foods with similar-sounding names, like takoyaki, give her a partial boost too, though nothing quite matches the taco effect.
