The mahjong club goes to a mountain retreat training camp to improve their skills. The first day is spent mainly having fun, and playing some normal games of mahjong. The next day, Hisa gives the first years (excluding Kyōtarō) special tasks. Saki plays mahjong online, but is dejected how easily she loses to others. Nodoka has to gain experience playing others in real life when she is more skilled playing online like she is used to when playing at home. Yūki does math drills in order to improve her ability to keep track of the score when playing mahjong. Afterwards, Yūki becomes depressed how she loses so much against Nodoka, Saki and Hisa, and the club president recounts how when she was a first-year, she was the only member of the club, but she kept with it and now she is grateful there are many new members. Yūki continues to play, and manages a win. The next day, Yūki, Nodoka and Saki go to see the nearby waterfall.
