Awai resumes her double riichi play whilst Hiroko deduces that Awai's play style stems from the corners of the 'wall' that the tiles form, though cannot determine how Shizuno overcame it. After Ryuuka once again uses Toki's power to put a stop to Awai's dealership, Shizuno soon starts winning hands against Awai as, having trained in the mountains like it was her backyard, she has strengths pertaining to the 'mountain' that the walls go deep into, affecting Awai's play style and moving Achiga into first place. As Awai finds herself unable to perform double riichis again, Shizuno's power also affects Himeko's combo, delaying her win on her hand. With the last hand, Awai becomes determined to at least knock Shizuno off the top position. However, her final hand doesn't score as much as she had hoped for due to Shizuno's ability, and the match ends with Achiga in first place and Shiraitodai in second. After celebrating their victory, Achiga go to visit the new stage being built for the finals, where Harue encounters the announcer who defeated her many years ago, Sukoya Kokaji. Feeling confidence from her team, Harue pledges that she'll become a pro player once she has seen Achiga to victory in the finals. As Achiga get pumped up for the finals, Nodoka and the Kiyosumi team head off to their semi-final match.
