About Shadow Dragon: The Fallen Angel Is My Teacher
The deadliest assassin inherits the blood of dragons. ... The Exorcist Clans failed and Earth fell. A few escaped to another world — including him — but the one he served betrayed and killed him. He should have died. Instead, he wakes on the day he was born. “I've returned to the past.” Earth is still standing and the Exorcist Clans have no idea of what's coming in the future.
