"I've been reincarnated as Issei?" (high school dxd harem x male Issei oc)

After he was accidentally killed, Toad Skywalker went to heaven and was sent to the world of high school dxd, as Issei Hyodo! But the only difference is he's not a pervert. He has the power of the red dragon emperor. He even won the hearts of numerous girls so now he's become the true harem king.
