Kohana Aigasaki transfers to Hoshinomori Magical Arts High School. On her first day, she walks around the school and observes different students with their specialties. She comes across Teika Ichijoji, who shows her to the dorm rooms. Kohana then meets her roommate, Juri Chikamatsu. Later, she encounters Teika again. To thank him for earlier, she gives him a small bouquet of flowers she arranged, before telling him that she has yet to make any sparkles. After giving the flowers to Teika, Kohana witnesses the production of her first sparkles. The next day in class, Kohana is placed in a committee to prepare for the Hoshinomori Summer Festival, Hoshi Fest for short. Upon learning her full name, Teika declares her to be his rival.
