The Tamano household is in chaos when Hinagiku's mother assumes that her husband has forgotten their fifteenth wedding anniversary. However, Hinagiku's father only pretended to forget because he misplaced his anniversary gift, a necklace, and was embarrassed. No sooner than things are ironed out, a stranger possessed by the devils snatches the necklace. When Momoko and Hinagiku apprehend the thief, Limone descends to ask Hinagiku to join the battle as a Love Angel. With the Saint Pendule, a special watch that appears on her wrist, Hinagiku transforms into Angel Daisy and saves the day as well as her parents’ marriage.

There seem to be more questions than answers. Pluie reports to Raindevila that a powerful wave came from a human and teams up with the devil Nocturne in order to investigate. Momoko is still overset by the mysteries surrounding her mother and the lost ring, and Yousuke suspects that Momoko and her friends are involved in something serious. Pluie kidnaps Yousuke and holds him captive in the devils' forest. The Love Angels, with Jama-P's help, embark on a dangerous rescue attempt.

Coerced into a devil's contract, Takuro continues his relentless pursuit of Momoko and flaunting the extraordinary new skills that Igneous is magically granting him. Hinagiku, who has known Takuro since childhood, becomes suspicious of the sudden changes, but the most pressing question is, who is Yanagiba taking to the school dance? Igneous makes another ineffective strike on the Love Angels by sending the devil Blackie.

Momoko, Yuri, and Hinagiku decide to knit mufflers for Yanagiba. When a group of girls gathers together to knit after school, Potamos becomes envious and calls upon the devil Fusuma, who creates a portal in the classroom that traps the other students in an endless labyrinth of linked dimensions. In order to rescue their classmates, Momoko and Yuri sacrifice their knitting projects. The devils interfere with the rescue, and the Love Angels have a close call.
