Wolfor

It isn't the world you know. There wanders a girl with jet-black hair, ebony clothes, and a strikingly blue, glowing eye.

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 devil, and from that day forward, he serves as an underling of Riasu, a high-level devil who is also the prettiest girl on Issei's campus.

Issei Hyodo is your average perverted high school student whose one wish in life is to have his own harem, but he's got to be one of the unluckiest guys around. He goes on his first date with a girl only to get brutally attacked and killed when it turns out the girl is really a vicious fallen angel.

Isei finds new troubles about to enter into his life and two even sleeping in his bed. While looking at an old photo album of Isei's, Kiba sees a familiar sword being held by an old friend of Isei's, which reopen's old wounds.
