After James and Lily Potter were told about the prophesy made by Sybill Trelawney from Albus Dumbledore concerning their son, they decided to go into hiding in Godric's Hollow under the Fidelius Charm. As Sirius Black was a far too obvious choice for their secret keeper according to James, Peter Pettigrew was chosen as their secret keeper despite a protest from Lily due to her having a very low opinion of Pettigrew.

The day before the Potters went into hiding, James and Lily Potter made a visit to the Gringotts Wizarding Bank operated by goblins in Diagon Alley in London, in order to set up a contingency plan should they both die.

While James went there to update the Potter family will, Lily went there to place an order for a potion known as the blood adoption potion, that despite being illegal to use on the British soil, was not that well known to the public and was fairly easy to get if you had enough money.

On Halloween, Wednesday 31 October 1981, Peter Pettigrew betrayed the Potters and gave up their location to the Dark Lord Voldemort.

As Voldemort entered Godric's Hollow, James ordered Lily to take their 1 year old son named Harry upstairs while he bravely fought against Voldemort and was killed by him. Lily, having been given enough time to make it upstairs to the nursery, placed their son Harry to his crib and opened up the drawer of the nearby desk to take out an letter and the blood adoption potion she previously bought, and placed them both in Harry's crib, then she activated the runes she set up as a safety measure. The runes were meant to send Harry and the items in his crib away from their world to another world to someone who had the ability to use magic and did not have any evil intentions toward him so he could be adopted by him or her. The runic spell was an original spell made by herself and was to be used as her last resort due to it being untested and it being unknown if the spell worked as it should.

While the runic spell was powering up, Voldemort blasted the door off its hinges with an Exploding Charm.

"Not Harry," pleaded Lily as she tried to stall for time, knowing that the spell would need more time to activate, "Take me."

"Step aside woman," ordered Voldemort, "and I will let you live." having promised Snape to spare the mudblood.

As Lily kept on pleading for him to spare the boys life, Voldemort grew tired of her voice and fired off a killing curse at her, thus killing her, while thinking Snape would soon move on from her. However the time he focused on Lily was all that was needed for the runes to take Harry away from there, making Voldemort curse at his own failure.

A week after the attack, the goblins released the Potter will to the public, revealing the Potter family secret keeper was Peter Pettigrew, which resulted in Sirius Black being given a fair trial that cleared him of all charges and allowed him to inherit the title of Lord Black. Although the wizarding world knew that Harry Potter was alive, nobody knew his location.

As the events were playing out in the wizarding world and the Dark Lord still alive, Harry James Potter was in another world being blood adopted by Sairaorg Bael as his new father and Kuisha Abaddon as his new mother, thus becoming a Pure-Blooded High Class Devil that would be named Hadrian Bael. He would not be seen until the Triwizard Tournament.

Authors notes:

The Blood Adoption ritual can only be used on very young children who have at least one magical parent, the maximum age being 3 years, the ritual will change the genetics to match that of their new parent, should both parents be magical two people can participate in the blood adoption ritual. As Harry has inherited James black hair and Lily's green eyes, the blood adoption will only change his facial features and body type. His new father Sairaorg has also black hair and his new mother Kuisha has green eyes in the anime. Hadrian Bael will turn 13 and will be given his own set of Evil Pieces, and months after having celebrated his 14th birthday Hadrian will be summoned back to the wizarding world to participate in the Triwizard Tournament by the Goblet of Fire.

I am not that confident in writing this story and should someone wish to adopt this story they can send me a message. My only requirement is that the pairing for Harry or as he now is known as Hadrian is with a woman or a harem with multiple women.
