In a realm divided into the human, angel, and devil worlds, the malevolent Raindevilla plots the annihilation of the angel realm with her demonic minions. To counter this threat, the benevolent goddess Aphrodite dispatches Limone, an angel, to enlist three schoolgirls—Momoko Hanasaki, Yuri Tanima, and Hinagiku Tamano—as the trio of love angels: Angel Lilly, Angel Daisy, and Wedding Peach. Tasked with vanquishing the devilish forces and navigating personal challenges, the girls must gather the Sacred Four Somethings to bring harmony back to the angel world and vanquish Raindevilla's tyranny once and for all.
