Yuu is the older sister of Kuro Matsumi and the fourth member to join the new mahjong club. 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 has blonde hair and green eyes. She wears the standard Achiga Girls uniform with black pantyhose, a pink scarf, and pink mittens. Kuro says she also wears glasses and a face mask whenever she goes out. She also wears glasses when she's reading or trying to look closely at something.
She is polite, shy, and has a strong relationship with her sister. Yuu's biggest quirk is that she is very sensitive to the cold so much so that she freezes even during the summer.
Playing Style / Abilities
Yuu's ability is that she can draw alot of manzu and chun tiles, so her hand is manly composed of these tiles. She also draws these tiles because she feels warmer drawing in warm tiles. When that playing style fails, she draws in all red tiles and becomes difficult to defend against. According to Kuro, Yuu is just as good as she is at mahjong. According to Toki Onjouji, Yuu has similar playing style to her.
Introduction ArcYuu is first seen under the kotatsu when Kuro and the others come to her house looking for another member for the mahjong club. After an explaination of who she is Kuro nominates her and Shizuno Takakamo and Ako Atarashi ask her to join. She then explains how she always wanted to join with the others when they where young but thought it was awkard before excepting their invitation. A while later the club gathers to look for another member and Yuu suggests that they go for Arata Sagimori and says that she was a big fan of Harue Akado. The next day everyone gathers to announce the completion of the mahjong club and to greet each other. A few months later Harue Akado joins the mahjong team as well and after another timeskip its spring.
With the start of the semester, Yuu and the others gather to offically start the mahjong club. In order to up their skill level the team was trained by Harue for the next two months. At the start of the Prefectural tournament, she and the rest were a bit nervous thanks to there being so many people and in their first match having to face Bansei High. However thanks to their training Bansei was no match for them and Achiga girls went on to win the whole tournament.
A few days later before the club gathered Ako asked where Yuu was and Kuro informed her that she was getting hugged to death by her classmates because they saw her on television. When everyone finally gathered, the club decided that in order to prepare for the nationals they would face some of the clubs that finished second in their prefectural tournament and Ryuumonbuchi was selected to be their first opponent. After the matches, Yuu was confused when Koromo Amae tried to exlain who had defeated her in the prefectural tournament. After a few weeks Achiga had beaten all their opponents except for Ryuumonbuchi. Later on the team held a training camp to further their skills and at the end of that they headed for the nationals. Stoping at a rest stop before Tokyo, Yuu was revealed to still be asleep in the car.
