Anime adaptation of the spin-off manga that stars the black-silhouetted "criminal" that appears in representing the mystery culprits.

In the previous series "Kite," a killer—Sawa—suddenly disappears after she avenges her parents' death, and no one knows where she is. Several years later, a figure dances airily on the dark side of a big city. She is an angel of death, killing her victim gracefully and disappearing. Monaka is a normal high school student, though this quiet and modest life has a darker side. An angel of death is Monaka's other persona.

A collection of short stories, all of which are perverted to various degrees.

As a result of a traffic accident, Limit-chan is reborn as a cyborg and is given three types of supernatural powers. However, there is a catch: if she uses too much of them, her life will come to an end.
