High School DxD

Issei Hyoudou is a high school student who spends most of his time objectifying women and dreaming of having a harem. His life takes an unexpected turn when he's killed by a beautiful girl on a date, who turns out to be a fallen angel. Revived by Rias Gremory, a top-class devil and senior student, Issei becomes her servant and joins the Occult Research club. As he navigates this new world of angels and devils, Issei must balance his secret life with his relationships and schoolwork.
