Reincarnated Demon King! a Bad Start and Killing a God by the Way

At the beginning, the god accidentally killed him with lightning! In order to compensate me, let me be reincarnated as the Lord of the Demon Realm! Unexpectedly, he turned into a little shota demon! There is also a slightly perverted deacon. As the Demon King who rules the Demon World, I just want to be in trouble, but why does trouble always come uninvited? Outwit the gods, devour all things, and eventually grow into the supreme demon!
