The last team left in the tournament is Hokuto Gakuin, Kyoritsu's long-time rival. Saki tells the guys that they can compete in the co-ed tournament with Honoka the following day if they win. Meiritsukan has already made it to the co-ed tournament, allowing Honoka to go up against Mayu once again. As she has never been allowed to compete in the national tournament as a female, Honoka strongly desires to compete in the co-ed tournament. Banding together for Honoka's sake, the match begins. However, Ren is injured, and Daiki loses in the next matchup. The pressure is on the remaining three to win all their matches.
