Issei didn't know what he was getting into when he made a deal with The Red Dragon Emperor, all he knew, was his friend was in danger and he needed to save her, no matter the cost. Eventually, Issei finds himself mixed up in the world of Angels, Devils and Fallen Angels, however, at least he has a way to fight for those he cares about. Less perverted, powerful, Dragon Issei. Harem.
