For Whose Sake?.Taiga and Ami must compete in a fifty-meter swimming race. Ryūji tries to encourage Taiga to practice in the swimming pool, but she prefers to practice virtually. Taiga later refuses to participate in the race after Ryūji assumes how she really feels about the competition. However, Taiga decides to show up last minute on the day of the competition. Taiga has a leg cramp during the race, and Ryūji jumps into the swimming pool to stop her from continuing. He lets her go to push for the lead after she declares that she wants to win this for him. When a few boys are pushed into the swimming pool, Ryūji is knocked out, prompting Taiga to turn around and save him, thereby losing the race. Ryūji wakes up surrounded by all the students, and a shaken Taiga yells out that Ryūji is hers. Although Ami planned on taking Ryūji to her beach house alone as a result of winning the race, Taiga, Minori and Yūsaku insist on tagging along.
