During a rainfall, the roof in Akari's dorm room starts leaking, resulting in Akari and her roommate, Yuu, having to move into separate dorms, with Akari moving in with Sumire Hikami, who she met by coincidence that morning. After receiving new Aikatsu Phones and cards from Orihime, Akari and Sumire try to break the ice between them, though Akari doesn't get to learn much before Sumire has to go off to her lessons. Akari is soon alerted about an audition to become Ichigo's manager for a day, inviting Sumire to audition alongside her and spend the day training with her, though it would increase the number of rivals she would have. Sumire, who had mostly practised by herself and considered all the other students rivals, felt happy that she could spend time practising with a friend. In the end, Sumire wins the audition, while Akari, despite not winning herself, feels happy that she has become closer friends with Sumire.
