Highschool DxD: The Monstrosity of the Abyss

His soul has been tainted in the depths of the Abyss, as the Abyss itself, who happened to be a very powerful omnipotent being. Offer the soul a second chance of life. But unlike most fanfics, due to the tainted soul of his, he wasn’t given any kinds of wish, and his choices of anime worlds was limited to three. First being Dragon Ball, which was denied, due to the fact, it is very dangerous. Second was Fairy Tail, with a twist that everyone’s genders are swapped. And the soul’s geek/otaku’s side cannot handle the fact, there is a female Gray and Natsu in that world. So, he picked the last choice, which was Highschool DxD, with the only twist, there both OCs and characters from other animes will be existing in that world. As the otaku/geek he is, the soul was overjoyed as he accepts this offer, with no wishes, and only power he has is something he soon will call Abyssal Power, the power from the Abyss itself. Little did anyone will know, how much an impact he will have on this parallel world of DxD. And when the Supernatural, the world that houses the Devils, Angels, Fallen Angels, Gods, and even Dragons, and many more. Many will react differently when they find out about his existence. Many will want to hunt him down. Many will fear him, and his Devil and God-like Powers. And there also those that admire and worship his existence. But one thing is clear, the day when he awakened the powers known as the power of the Abyss, Abyssal Power. Will be the day when the Monstrosity from the Abyss is born. And his followers, who also create as much chaos in the Supernatural as he does.
