Synopsis/Details
An angel, Rhea, completes 16 stars, the age all the angels start their stage on Earth, at School of Eden, in order to become a 100% Guardian Angel. When the school gets intruded by demons, Rhea and her friends are abducted and transported to Hell, where they’re held in a mansion by an arrogant sadistic demon, Kato. As Rhea learns to survive in the world of nighttime, she is shocked to discover that she’s a Supreme Guardian — possessing powers that intimidate all demons. Rhea and Kato’s relationship starts with annoyance but soon develops to something else. The two make a deal to travel to Earth and engage in a duel over a human’s soul: if Rhea wins, Kato will set her and her friends free; if not, she will stay and will never try to escape.
After Rhea wins the battle, Kato brings her back to Hell and refuses to let her go. While he learns to accept his feelings for Rhea, she lives in denial and tries to escape at all cost. Kato gets punished by the members of the Lower Spheres, the higher ranking demons, for failing to seduce Rhea and steal her powers. Witnessing Kato’s death, Rhea realizes her feelings for him as well as a shocking truth about the demon.
Returned to Heaven, Rhea faces the consequences of her love towards Kato and is now called a ‘Fallen Angel’. That sends Rhea back to Hell, where she faces Isis, the master of the Lower Spheres, who asks Rhea to turn to the dark side. After Rhea refuses, Isis orders Kato and all the Hell creatures to kill her. Rhea senses the good in Kato as he’s unwilling to hurt her and confesses her love for him, causing the land to explode. Rhea and Kato escape and find themselves in Limbo, the border between Heaven and Hell. Facing the judgment of the Upper Spheres, they make a decision to walk into the Infinite Light to be reborn as humans without memories and have a chance to be together in the human world.
