Oni To - Tengoku Drama Cd ^new^

: The story kicks off when Oni visits the infirmary to check on a truant student. Tengoku reveals he has been watching Oni since he started at the school and suddenly kisses him, claiming Oni is actually "pure-hearted."

An Animate Limited Edition was released, which often includes bonus materials such as cast talk tracks or exclusive booklets.

Fans of the original manga often highlight the "lovely" nature of the work despite its darker undertones, such as early themes of sexual harassment that are eventually resolved as the characters fall in love. The drama CD adaptation is praised for its ability to maintain this delicate balance of tension and romance through vocal performances.
