Hoshi is still depressed after seeing Nino kiss Kou, and ends up getting dragged around by Stella who wants to cook something for Sister. Kou becomes concerned over how Stella would react if she learned of Sister's attraction to Maria, which soon becomes apparent when Hoshi blabs about it. Stella becomes furious and vows revenge on Maria. The two eventually face off, but Stella is overwhelmed by Maria's speed and skill, though the two end up becoming friends. The next day, Hoshi tells Kou about his past life as a famous musician, how he met Nino and how he came to wear a star mask, though Kou doubts the legitimacy of his story.
