To Harry, the worst part of his life started when he was four, on October thirty-first, nineteen eighty-one when Voldemort attacked.

He found that both adult Potters were out of the house, and their children were being looked after by a babysitter.

He moved into the house, quickly dispatched the babysitter, and started to find the one that would stop him.

And he found them.

Both children of the Potters.

A girl who was bearly and her older brother.

Voldemort pulled out his wand and pointed at the older of the two children.

As the wand tip glowed green, a voice filled the air.

{I would not do that if I was you,} The voice said as a red glow filled the room.

{If you send that curse, I will not let it land, and you will die,} The voice told him.

But he did not care as he was Lord Voldemort.

Nothing stood in his way.

"Avada Kedavra," Voldemort called out as the streak of like shot out the red shot back at it, cutting through the curse.

{Chaos Obliteration} The voice called out as the curse rebounded and wiped the dark lord to praises, and then the red energy shielded both children as a wraith fled the house.

But as it was said, this was the start of the worst part of his life.

When both parents returned to find their home, they ran upstairs and saw their children unharmed with a robe and wand on the floor.

The man was a tall, thin man with hazel eyes and untidy black hair that stuck up at the back.

He wore black trousers, a dark red belt, a tucked-in white button-up shirt, and a dark brown robe over his shoulders.

"Lily, we have to get Albus to have a look before going after Peter," The man said to his wife.

His wife was beautiful, with thick, dark red hair that fell to her shoulders and almond-shaped, bright green eyes.

She was dressed in a red blouse with an ankle-length brown skirt; like her husband, she had a dark brown cloak on her shoulders.

"I know, James," Lily told him as they picked up their children and apparated away.

They both appeared outside a large castle before rushing in, holding their children.

The two of them moved from floor to floor until they reached the entrance to where they needed to go, guarded by a gargoyle, "Skittles," James told the gargoyle, who moved aside, and they made their way in.

They walked up to a man behind a desk.

He had a long white beard and was dressed in a flashy purple robe with silver stars over the robe.

"James, Lily, what are you doing here," The man asked them.

"Albus, Voldemort attacked," James said to the man, whose eyes shot wide before looking at them.

"Then Sirius...," Albus said before James shook his head.

"It was Peter that we had as a secret keeper, and Sirius made sure to keep that as a lie so that they would go after him instead," Lily said as she held her son close.

Albus nodded as he looked at the children, "Are they alright," Albus asked the two of them as he looked at them.

"Rose and Harry are fine from what we saw, but we came straight here," James said as Albus nodded, pulled out his wand and incantated his breath before both children glowed.

But the glow around the boy was slightly lighter than the one about the girl, "It seems that Harry here is weak on magic while Rose is fine, and they seemingly both have scars on their heads," Albus said before someone burst into the office.

It was a thin man with sallow skin, a large, hooked nose and yellow, uneven teeth who was dressed in flowing black robes which made him resemble 'an overgrown bat' with shoulder-length, greasy black hair which framed his face in curtains, curling lips and dark, penetrating eyes that resembled tunnels.

"Dumbledore, he's dead," The man said as he went as he rolled up his left sleeve showing a tattoo of a skull with a snake.

The symbol of a Death Eater.

The Dark Mark.

But it was slightly faded but not gone.

Dumbledore walked over to him and looked at the mark for a while before shaking his head, "No, Severus, he is not," He said as the people bar the children, were both shocked and confused, "It seems that he is still out there, but has been weakened greatly by Rose Potter," Dumbledore said as James looked down at his daughter.

"How did Rose do that," James asked as Albus shrugged.

"I do not know, but what we know is that Rose Potter is the Girl-Who-Lived," Albus said as he looked at the little girl.

Then word spread as the supporters of Voldemort fell and hid while lying to keep themselves from being caught.

But back to the Potters, where nothing really changed.

But that did not stay.

And it was Harry that was getting the wrong end of it all.

After his fifth birthday, things changed as the months went by, with small things changing.

Like after the first January of the following year, James forgot to call Harry down for food.

A house elf called him down instead.

Two months later, he was left at preschool before the school had to call his mother to pick him up.

In May of that year, he was left at home alone with just the house elves as the Potters were envied out to a party.

The first significant change was when he turned six and forgot his birthday.

That same year, in October, his godfather visited Rose was all Sirius wanted to see.

It was that same year, and he did not even get a letter, gift, or anything for that Christmas.

For the year that he turned eight, he was just forgotten about completely by everyone.

The following year, in April, was when everything changed for Harry.

He sat on a log near a lake by his house, where he could hear his parents celebrating something with his sister that he grew to hate.

He even hated his parents.

He looked at the lake longingly and nodded his head after thinking.

He started to walk towards the lake.

He knew that his parents would not care.

His godfather would not care.

No one would.

"Going for a swim," A male voice said behind Harry as the boy stopped and turned to see a tall, handsome man with blue eyes, a youthful face, and slicked-back white hair.

He wore a purple Victorian outfit with a white cravat, a large red jewel around his neck, and a monocle over his left eye.

"Something like that," Harry said as he returned to the lake.

"May I ask your name, young man," The man asked Harry, who looked over.

"Harry," He replied.

"Just, Harry or," The man asked him.

"Harry Potter," Harry said quietly.

The man looked at Harry with a sparkle in his eye before smiling gently at Harry, "So you, my eldest grandchild," The man said as Harry looked shocked.

"You, my grandfather," Harry asked with a raised brow as the man furled his brow.

"Did your mother not say anything," The man asked as Harry shook his head, "I shall have a word with her about that, but allow me to introduce myself; I am Sparda," The newly introduced himself before he frowned at Harry.

"Now, would you be so kind as to tell your grandfather why you intend to end your life," Sparda asked Harry, who looked back at the lake.

"I practically forgotten in my own home," Harry said before shaking his head, "No, that's not my home," Harry told him.

Harry looked away for a moment, and for that moment, he missed Sparda's eyes glowing slightly yellow.

When Sparda looked into the mind of his grandson,

And he did not like what he saw.

"And how are you forgotten," Sparda asked him.

"I have not had a birthday since I was five; I have not been celebrating Christmas for the last two years," Harry said as Sparda's eyes widened before looking at the house.

"I see," Sparda said before he nodded at himself, "If I could take you away from this place, to somewhere that you would find happiness, would you go for it," Sparda asked his grandson, who nodded.

"I would," Harry said as Sparda smiled.

"I see, Sebastion," Sparda called out as a man appeared out of a magic circle.

He was a tall, handsome man with black hair, reddish brown eyes, pale skin, and black fingernails dressed in a butler's outfit, which consisted of black trousers, a six-buttoned double-breasted tailcoat, and a grey vest; he also sported white gloves, a pocket watch, and a chained silver lapel pin bearing the crest of some kind.

"Yes, my lord," Sebastion said as he looked at Sparda and then at Harry, "How may I be of assistance," He asked.

"I'm going to have a word with my daughter; can you tell Harry what and who we are and who he is as well," Sparda said as he looked at the house that was not that far away.

"I can do that, my lord, but I may need some help, so may I have some assistance from your Queen, lady Albedo," Sebastion said as Sparda nodded.

"You may call her," Sparda said.

As he walked into the house, he felt the magic in the air and heard a female voice.

"So this is Sparda's grandson," He heard before he reached the house and knocked on the door.

"I'll get it," Sparda heard his daughter's voice through the door before it opened, and she stood before him.

"Dad," she whispered as she looked at him before hugging him, and he hugged her back. "Come on in," she said as she led her father into the house.

"What a lovely house, Lilith," Sparda said as he took in the house around him.

Lily smiled at that, "So what brings you here," She asked him as he turned to her.

"I have finally finished dealing with that clan that killed your mother, and so I have come to visit, and on my way, I was told you had children," Sparda said as Lily nodded, "A son and a daughter," Sparda asked her as he knew from both the information and Harry, but he did not need Lily knowing that.

Lilly nodded again at him, "Yes, Harry and Rose," Lily said as Sparda nodded with James walking in carrying Rose, "And here Rose is now," Lily said as she smiled at her daughter.

"And where is Harry," Sparda asked him.

Lily looked at James, "I think he's upstairs, but he must be busy," James said, not seeing Sparda's eyes glow yellow for a second.

But Lily saw it, "Da-," she said before two large dragon-like wings formed behind him as black as night.

"So what Harry had told me was not a lie after all," Sparda said as James looked shocked at his father-in-law, "And to think you would be worse than your sister," Sparda said as he looked at Lily.

"Da-Silence Lilith, your son was about to go over to the lake and drown himself," Sparda interrupted Lily, who looked shocked, "And to think that I had raised you better than that," Sparda said as his blue eyes turned a deep crimson and he held his hand out as a sickly green and purple smoke formed around his hand with Lily looking shocked.

"Now, Dad, there's no need for this; Harry wouldn't have-" Lily tried telling him, but Sparda scoffed at her.

"Oh, he would as I looked into his mind and saw the truth, Lilith," Sparda said as the smoke shot out his hand and into the chests of Lily and Rose before the smoke pulled two orbs out of their chests.

Lily fell to her knees while Rose fell to unconsciousness.

They were glass orbs with a rainbow of coloured energy within them, "Harry is under my care now, so I will be signing him up for another school away from here, am I understood," He said as he put the orbs into his coat pocket.

James said nothing as he was still in shock but held his daughter tight.

Lily looked up to her father with tears in her eyes and saw that she could see the ghostly face of her mother looking disappointed in her.

"Yes, Father, but can I make a request," Lily said as he looked down at her and nodded, "I get yearly, if not monthly, letters to see how Harry is doing," She asked him.

Sparda looked down at her before he nodded, "Yearly letters, each one will arrive on this day moving forward, and they will be delivered by Sebastion, and if you want, he will be here to receive a letter for Harry in return," Sparda said as Lily nodded.

"I'm alright with this arrangement, Father," Lily said as Sparda nodded.

"I shall see myself out," Sparda told them as he went for the door but stopped, "Lilith, know that while I am disappointed in you, I do still love you, and if you ever need of me, just summon Sebastion and he can send the message on to me," Sparda told her before he walked out.

When he walked out, he saw that his Queen was there.

She was a tall, beautiful woman bordered on sexy and had lustrous jet-black hair with pale skin and golden eyes, wearing a pure white dress with silky gloves covering her slender hands and a golden spiderweb necklace covering her shoulders and chest.

"So I'm a quarter Devil," Harry asked the woman, who nodded.

"That's right, but you are also royalty of the underworld," She told him before she saw Sparda walk over.

"Hello, Albedo, how is teaching my grandson," He asked her as she looked at him.

"Doing good so far, but we need to awaken the Devil part of him before he can go any further," Albedo said as Sparda nodded and pulled out one of the glass orbs.

"Harry, I must ask you this: do you want to join me in the underworld as the prince of it all; you would meet new people, go to another magical school and many more things," Sparda said as Harry looked at him before he smiled.

"I'll accept," Harry said as Sparda handed him the glass orb.

"Push that into your chest, and you will awaken the Devil half of yourself," Sparda told him, and Harry did as he was told and pushed the orb into his chest.

Black and crimson energy gathered around him before it burst out of him into a pillar of energy as Albedo and Sebastion covered their eyes and steadied themselves from the shock waves that the energy pillar was sending out.

Sparda stood there looking deep into the pillar of energy, "I can feel the power of his magic, chi, ki, and reiryoku," Sparda thought as a smile graced his face, "And I can tell that he has a Sacred Gear that is Longinus in power as well," He added as within the energy he started to make out a shape from within.

It was Harry's shape as the energy was soon pulled into him.

He had six dragon-like wings sprouting from his back.

"Well done, Harry," Sparda told him as Harry smiled up at his grandfather.

A magic circle formed underneath them before it teleported them away and into the underworld in a large fancy room where Sparda turned to Sebastion, "In form, the other maids and butlers about Harry and so have someone go retrieve his things from his old home," He told the man.

"Right away, sir," Sebastion said with a bow before leaving the room with Albedo in tow.

Sparda then looked down at Harry, "Shall we have a look around," He asked his grandson, who nodded, and the two of them walked around the home that they were in.

Years soon flew by as Harry was enrolled in the Mahoutokoro School of Magic and was trained in all types of arts.

He was gifted a sword from his grandfather that was once his and taught how to use it by his grandfather's knight, Meliodas.

And with each year passing, Harry started to gather his Peerage and grew a friendship between himself and the heiress of the Gremory family.

Before Harry's final year at Mahoutokoro, he was called to his grandfather's office in the underworld, where he knocked on the door, "Come in," He heard his grandfather say.

"Yes, grandfather, you summoned me," Harry said as he looked at his grandfather.

"I need you to look into something for me," Sparda asked him as Harry raised a brow.

"Sure, what do you need," Harry said as Sparda handed him a letter and once he read it, Harry's eyes became blood red, "I thought that you told them to call it off," Harry asked as he looked up.

"I did, but it seems that Phenex did not get the message," Sparda said as a red jewel formed on Harry's shoulder.

{Ddraig is here} A female voice said as Harry and Sparda closed their eyes and felt the power of a dragon entering the underworld.

"It seems that the red dragon wants to fight for Rias," Harry said as Sparda nodded, "I'll go there, and even if the red dragon is to lose, which I don't believe for a second, I'll deal with Phenex," Harry said as Sparda nodded and Harry walked out of the office.
