Young demons Rara Yamabuki and Bibi Kurosawa come to the human world in order to do evil deeds and become full-fledged demons. Rivals in love, they search for the legendary demon, Hiroshi Akusawa, in order to win his heart though they don't even know what he looks like. While Rara is standing on the roof, classmate Retsu Aku mistakenly believes she's going to kill herself and grabs her, "flying" down with her to safety. With that, and hearing him called "Aku," Rara believes him to be Akusawa, but later learns he is just a normal human and that Akusawa isn't nearly as desirable in person. When she uses her power of flight to aid Retsu, which causes her to lose the power forever, Rara realizes she has fallen in love with him.
As the series progresses, Rara learns that Retsu has had the power to see ghosts since last summer. One ghost begins stalking Retsu to take over his body. Rara tries to protect Retsu, using her power of invisibility, but in doing so accidentally kisses him. After Retsu learns about the ghost, he is able to identify the ghost and remind him of his past, allowing the ghost to move on to the afterlife. Rara, however, has lost so many of her powers helping Retsu that her mother and other demons warn her that if she does not kill Retsu, she will soon disappear "into the darkness." Rara is unable to do it after Retsu confesses his own love for her. They skip school to spend the day together, and Rara decides she will enjoy whatever time she has left with him. Bibi, unwilling to let her "rival" disappear, traps Rara, then disguised as Rara tries to kill Retsu herself. Retsu sees through her and Rara is able to catch up to them in time to warn him that Bibi wants to kill him. Before leaving them alone again, Bibi explains to Retsu about their being demons and that Rara is going to disappear because of her love for him.
Retsu tells Rara to kill him so she can live, but she refuses. She kisses him, using the last of her powers to take away his ability to see ghosts, then disappears. Instead of going into darkness, she begins going to the light. Retsu promises to find her wherever she ends up, and tells her not to forget him. Later, Retsu is shown having forgotten what happened, though left with a feeling he is missing someone. Bibi uses her own powers to walk by him disguised as Rara and whispers "don't forget me" unlocking his memories.
In a hospital, a girl named Sara wakes up from a six month long coma, having been stabbed in a street fight with a guy. Beside her is Retsu, who tells her that he is her boyfriend. A delinquent, she threatens to kill him, but he hugs her and says she can't, and that he knows the real her.
