A second later, Tsubaki bursts into the office and proceeds to beat up Tsukasa. She then asks the principal to "ignore him," but Tsukasa yells at him to "expel them." Tsukushi interjects, saying "I'll leave this academy!" Rui enters and and says he will leave instead. Akira Mimasaka then promises to "quit" too, leading to an argument with Tsukasa. Tsubaki yells at everyone to stop, before suggesting they settle this through "sports." Perplexed at first, they then agree to play a three-on-three basketball game.
Tsukushi, Rui, and Kazuya Aoike begin practicing, despite their obvious disadvantage. Rui then shows off some of basketball skills. He promises them that they will not lose the game, saying "I have something I want to protect, too." That night, Tsukushi meets Tsukasa on her way home. Initially suspicious, shes tells him "You're not going to have an easy win tomorrow." As such, he surprises her by hugging her and saying "If you'd only say that you loved me, I'd cancel the showdown tomorrow."
A one-page illustration of Rui holding a basketball was originally published with this chapter in Margaret. In the art book, the image accompanies a character profile on Rui. It was also included in volume four of the series' complete edition.
