I, Issei Hyoudou, am a second-year high school student but I'm not her age. She went out with me! It was bound to happen but why did she kill me!? Still, doesn't this world have a God!? The most beautiful girl in the school, Rias Gremory, saved someone like me. The truth hit me that it wasn't God or Buddha, but a girl who said she was a Devil. "You have been reincarnated as a Devil. Work for my sake!" The curtain was raised, thus my life as a Devil servant who was attracted to the award of my senior's tits began.

## Trivia

* Diabolos means "Devil".
* Originally the first volume was meant only for Issei to be just a human who helps Asia. However, that kind of development would take many volumes to keep up (especially since Issei does not have any specific talents to begin with), so Ishibumi changed Issei to be a Devil and introduced Rias.
* Ishibumi wrote the entire plot from the scene where Asia died and Issei prayed to God.
