Yumachi Middle School

Yumachi Middle School is located in the city of Matsue in Shimane Prefecture.

Kyouka Inamura, Kanna Ishitobi, Himari Kanazawa, Rena Mototsune, and Shino Shiratsuki started studying here after graduating from Yumachi Elementary. Hayari Mizuhara also went here since the middle school from her district didn't have a mahjong club.

Alumni of Yumachi Middle School include Kousuke Shiratsuki and probably Nana Shiratsuki.

History
The year before Shino entered the school, the team of Yumachi Middle School was defeated during the prefectural qualification tournament of the All Japan Middle School Mahjong Tournament. The strong third year players graduated.

Club
The remaining club members are two second year students, the club president Shizuku Nozu and Rio Takuwa, as well as two third year students, Mirin Katsube and Ayuko Yamamoto. The previous year, all four were defeated in the first round of the city individual tournament. Kyouka Inamura, Kanna Ishitobi, Hayari Mizuhara, Rena Mototsune, and Shino Shiratsuki joined the club. The club advisers are Chisa Sakane and the elderly Nakamura.

The mahjong club room has two automatic tables.
