Devil Harry and his peerage (HP & Highschool DxD crossover)

[Guest Draynuy]

The concept of this challenge is simple, Lily found an old ritual to summon a Devil, who will fulfill a wish from the contractor. The night of Voldemort's attack, Lily activates the ritual and she wishes the survival and happiness of her baby, Harry.

Sirzechs Lucifer is the one who responds to the call, he uses the sacrifice of Lily to create a protection to Harry, the fragment of Voldemort's soul to transform Harry in Devil and a special mutated and fairy king of a special set of Evil Pieces to ascend him into a High-class Devil. Then he use the mutated queen of, now, Harry's set to reincarne Lily. After a bit of explanation on the situation from each other, Sirzechs departs before Sirius and Hagrid come but he promise that he will send someone to explain the new world, of which Lily and Harry are part now, and teach all what a Devil must know.

Eleven Years laters, Harry is ready to go to Hogwart, complete his Peerage (of which a good part will become his Harem) and take his righfull place into his two World. How will Dumbledore, Voldemort and Wizarding Britain will handel this new Harry Potter.

Other Detail:

Sirius is found innocent but Peter manage to hide (he reappears much later (When Percy is eleven) at the weasley as Scabber) and Remus disappears until Harry's third years (because a bit of manipulation from Dumbledore).

In Third year this is Bellatrix who escapes and seems to want revenge but it is discovered later that she was brainwashed by spells and potions to become a pureblood fanatic, she must be proved innocent and she joins Harry's Peerage (and his Harem)
