After being killed on his first date, idiotic and perverted Issei Hyodo is resurrected as a demon by Rias Gremory only to be recruited into her club of high-class devils.

The story follows Issei Hyodo, a dim-witted, lecherous second-year high school student who is killed by a girl on his first date ever. Issei is reincarnated as a demon, and from that day forward, he serves as an underling of Rias Gremory, a high-level demon who is also the prettiest girl on Issei's campus.
