Empowered by the sinister Eternal Worms, Misty May returns to terrorize the school and hunt for Jibril's amore. As Rika and Nao struggle to stop her scandalous crimes, they are joined by Nagi, a new angel from heaven who requires a physical "amore charge" from Nao to unlock her powers. While Hikari falls victim to the worms' cruelty, the battle reaches a turning point with the sudden arrival of the mysterious Heavenly Angel Jibril Zero.
The conflict escalates with the appearance of Jibril Zero, an artificial heavenly being who is eventually captured by the demon Feitus and his amore-absorbing creation, Super 32-x. Simultaneously, a corrupted, devil-form Hikari orchestrates a sadistic "health lesson" at school, forcing Rika into a series of humiliating encounters with her classmates. Naoto and Nagi rush to intervene, only to realize that Hikari has fully fallen to the side of the demons.
