松実 宥

优是阿知贺女子学院三年级的学生，也是玄的姐姐。她小时候想和其他人一起加入儿童麻将俱乐部，但因为自己年纪较大，觉得会很尴尬。她非常怕冷，所以去任何地方都会把自己从头到脚裹得严严实实。优有礼貌、害羞，还有点容易受人摆布。然而，她有时也很坚定，即使面对不利的局面也绝不屈服，并决心赢回妹妹失去的所有分数。她和妹妹的感情也非常深厚。 优的能力是她能摸到很多万子和中（红）牌，所以她的手牌主要由这些牌组成。她摸这些牌也是因为她觉得摸暖色调的牌会感觉更暖和。因此，她的持牌分布通常偏向于字牌。当这种打法失效时，优会摸进所有的红牌，变得难以防守。

Yuu is a third-year at Achiga Girls' Academy and the older sister of Kuro. When she was younger she wanted to join with the others in the children's mahjong club but she felt it would be awkward because she was older. She is very sensitive to the cold, so she covers herself head to toe when she goes anywhere. Yuu is polite, shy, and a bit of a push-over. However, she can be determined at times, refusing to buckle even when faced with unfavorable situations, and being determined to win back any points her sister lost. She also has a strong relationship with her sister. Yuu's ability is that she can draw alot of manzu and chun (red) tiles, so her hand is manly composed of these tiles. She also draws these tiles because she feels warmer drawing in warm tiles. As a result, her tile possession distribution is generally skewed toward the character tiles. When that playing style fails, Yuu draws in all red tiles and becomes difficult to defend against.
