Private Paradise Academy is the school the AiPri characters attend. Most of the students are girls, but Nanaura Subaru is the only boy. The principal, Oscar Victoria, wants the students to focus on their studies instead of AiPri, but the student council members secretly participate in AiPri activities, on a mission to show its good side. The West Lily dorm has double rooms, while East Rose has single rooms. All middle school students live in the dorms. The West Lily dorm houses Aozora Himari, Hoshikawa Mizuki, Mitsuba Airi, Shinomiya Rinrin, Igarashi Julia, and Rokudo Eru. The East Rose dorm houses Ichijoji Sakura, Nikaido Tamaki, Mamiya Chii, Nanaura Subaru, and Nanaura Otome. Hachioji BiBi seems to live separately.

Among them, Guest arrives today as a new transfer student. Of course, you know a fair bit about AiPri.

The AiPri Brace is a special bracelet that opens the secret door to the AiPri-verse. Guest is secretly wearing one. It's white.
