Demon Lord Dante.

魔王ダンテ

Demon Lord Dante (Japanese: 魔王ダンテ, Hepburn: Maō Dante) is a manga series written and illustrated by Go Nagai. The series tells the story of Ryo Utsugi, a student who finds himself in the body of an ancient demon known as Dante and sees himself in the middle of a conflict between God and the devils. Nagai's main influence to create the work was Gustave Doré's illustrations of Dante's Divine Comedy.
