Asunaro Kohinata picks up a mysterious object that falls from the sky and takes it home. In doing so, he accidentally releases the demon Zepafur from captivity. As repayment for releasing her, Zepafur uses her powers to make Asunaro's fantasies come true in the form of the "Lovey-Dovey Harem Royale". Furthermore, Zepafur isolates Asunaro from his parents by sending them to a country called the Purupurupicopyo Republic on a business trip. Zepafur appears before one of Asunaro's crushes, a classmate named Serika Furuwada. Serika is initially resilient but is forced into the Harem Royale game when Zepafur repeatedly tortures her. While carrying out her first "daily mission" for Asunaro, Serika learns of the other three participants: Saya Tatewaki, Heather Shinonome, and Liru Yumezuka. Serika organizes a meeting between the four and proposes a boycott of the second mission. This boycott leads to each of the four losing the second round of the game and reveals the existence of a fifth participant. The four girls work together and eventually determine the identity of the fifth participant: Ren Suigyokuin.
