Summary
After the club has been revived, they realize they are still short on 2 more members to go for the Nara Prefecture tournament. Kuro takes Shizuno and Ako to meet her older sister, Yuu Matsumi, who later agree and becomes their fourth mahjong club member. The next day, Kuro asks her classmate, Arata Sagimori, a fan of Harue during her prime, though at first she refuse but later agree to and joins as the fifth member. During the winter, Harue's company manga team had become defunct, leaving Harue downhearted. As she visits Achiga for some nostalgia, she is surprised to find Shizuno and the others playing.

Wanting to experience the inter-high nationals once more, Harue decides to become the club's advisor and coach. With the mahjong club officially reformed, the girls begin training for the prefectural preliminaries. Later in the evening, Ako encounters some of her former classmates who went on to attend prefectural rival Bansei High.
