Summary: Harry Potter was banished from his home dimension after committing a crime against the universe. Making the best out of his situation, he found what he has sought after all of his life, a family. Godlike!Harry x Yasaka.

Disclaimer: I do not own Harry Potter or High School DxD

A/N: After seeing many crossovers in this section and finding the same overdone plot over and over, I thought I'd try my hand at writing something somewhat at least semi-original. As Harry will seriously be too overpowered, I plan not to focus so much on battles as those will be seriously boring and one-sided, but rather at the character interactions between the many characters in the DxD world. To me, it is not the epic battles that make the story interesting (though they do certainly add quite a delicious flavor if written correctly), but rather the plot and character developments of the characters as they go through their adventures.

It's my first time I am trying to write such a story so please take care of me.

There might be lemons, though at this point, I am not confident in my ability to write one. Harem for Harry is not feasible at this point.

If my writing improves enough then maybe I will in the future…

Chapter 1

1.

Harry woke to the pleasant weight on his stomach. Blinking away the spots in his vision, he saw his daughter's adorable form on his stomach. Harry sighed. It looked like she sneaked on his bed again. He lifted her off him and gently set her down next to him. The movement caused his wife to wake and blearily stare at their daughter.

"Mmmwahhh. Hmm? Kunou? You sneaked into our bed again."

Kunou mumbled incoherently and wrapped her tails around her, falling right back into sleep.

Harry smiled fondly at his family. They might not be human but he wouldn't trade them for the world.

He had finally found what he has always wanted, a loving family of his own.

His daughter looked exactly like her mother, except for her eyes. She had inherited his bright green eyes, which he had inherited from his mother. Come to think of it, his daughter was the exact opposite of him, who only got his eyes from his mother and everything else from his father.

Yasaka sighed. "As much as I love our daughter, and I know how much you'd like to spoil her, this has to stop. She is getting older and needs to learn some independence."

Harry grimaced. He knew she was right but he couldn't deny his daughter anything. As someone who never had anything growing up, Harry felt it was his duty to give his daughter everything he had been denied as a child. If he had his way, he'd spoil his daughter rotten. Fortunately, Yasaka ensured that didn't happen. She knew that that would only be bad in the long run.

"I'm sure it'll all work out." Harry said as he gave Yasaka a deep kiss which she eagerly returned. Letting out a sigh of content, Harry got off the bed but Yasaka pulled him back to her with her tails. Harry raised an eyebrow at her.

"What is it? I have to go to work."

Yasaka chuckled. "Come stay longer. I still find it hard to believe a god like you bothers with something as mundane as 'work'."

Harry sighed in exasperation. "I'm not a god, Yasaka-chan."

"Only you would be so humble… Harry, we both know that you're a god in every way that matters."

"Being a Magic God is different from having divinity." Harry argued weakly.

"Of course, husband. You are superior to those so-called gods."

Harry knew he will never win this argument. What she said was true and he knew it but he is not proud of that fact. Sure, in raw power alone, the gods in this dimension as well as other monstrous beings have him overpowered by a large margin. However, he had attained something that allows him to utterly annihilate anything in existence, even the most powerful of beings. He had obtained what was the ultimate goal of all wizards who actually wanted to learn the truth about magic. As far as Harry knew, he was the first and only one who had attained its power, making him the ultimate hacker in existence. In fact it would not be wrong to say that his ability was a cheat.

Still, a distinction has to be made. Harry knew he was different from real gods. In fact, he didn't like the comparison his title had to those beings. He was human and proud of it.

Even if being human lumps him with all the bad qualities that comes with the species.

He doesn't like his title but he had lived long enough to know that titles could make people take you seriously as they usually have a lot weight behind them.

There were downsides to his power though. Unfortunately, a mortal obtaining such power was a crime against the universe as it could very well unravel the fabric of reality. As such, the powers-that-be banished Harry from his home dimension and dumped him into this one. He had raged at the loss of his friends and had been homesick for a while but chancing upon Yasaka was definitely worth his 'punishment'.

"Papa… goin' to work?"

Harry looked down to see his daughter clutching his shirt while rubbing her eyes. With a large yawn, she gave him a hug. Harry returned the hug and kissed the top of her head.

"Yes, princess. There shall be no satisfaction to be found in things not earned. To truly appreciate the value of what we have, we must work for them."

Kunou nodded and opened her mouth to say something but quickly closed it. Harry caught the act and urged her to speak her mind.

"Papa… you said I can't sleep with you anymore…"

"Ah, yes. You're getting too big for all of us to fit in one bed."

Kunou looked at him as only a child could and pouted.

"But it feels so lonely sleeping alone." Kunou crossed her arms in thought.

"How about a pet?" Yasaka suggested as she took Kunou from Harry and ruffled her hair.

The idea had merit. If Kunou could have something to cuddle with at night, then maybe she wouldn't come to their bed in the middle of the night anymore. It has been a while since they've had sex without interruptions after all.

Harry thought about what would make good pets. If he was going to get her a pet, it would have to be something small and fluffy, like rabbits maybe. Judging by the excited look on his daughter's face, Harry resolved to get the best pet for his cute little daughter.

2.

Harry appeared in a secluded alley with an inaudible pop. Trying to look as casual as possible for someone who had just walked out of an alley, Harry began his trek to his workplace.

He waved to some students who greeted him as he entered the gates of the prestigious school. A few minutes later, he entered the class and greeted his students.

"Good morning class! Ah, what a wonderful day to start another round of physics!" Harry said excitedly, making his students groan.

One might wonder why a wizard like Harry would know so much about physics while he continued to trash its rules of a daily basis. The answer to this is quite simple. Many creatures were immune to direct effects of magic spells. However, a nice three ton rock thrown at terminal velocity could kill the same creature with no problem at all.

It is also easier and more effective to cast magic that works with the laws of physics. For example, a wizard would need an astronomical amount of magic power to use a spell powerful enough to blow up a city. On the other hand, it would be so much easier to conjure a device that facilitates fission and fusion reactions of atoms to create an atomic bomb which could achieve the same results.

A master wizard who knew physics, in theory, was a living Weapons of Mass Destruction generator.

Not that Harry would ever create such things of course, and besides, his cheat ability was more efficient in erasing threats anyway.

"So, last time, we talked about electric fields and electric field lines, today…"

3.

The day ended on a happy note and Harry couldn't help but think he was blessed with such smart students. But then again, Kuoh was a prestigious academy for a reason, with the average GPA was 3.2 and many reaching 4.0. Even so, it was amazing for high school students to grasp concepts that college students would be hard pressed to understand.

Now normally, Harry would just teleport back home and spend time with his family but this time, he had to stop at the pet shop to find a rabbit for his little girl. It was as he teleported to an empty park to walk to the pet store that a familiar voice called out to him, making him pause in his tracks.

"Harry! Fancy meeting you here." A man with brown hair and yellow bangs called out from where he was sitting on a park bench.

"What are you doing here, Azazel?" Harry asked his friend.

"Maa, maa, no need to be so cold. I was just watching the young mothers come here with their kids to play. And let me tell you, those were some damn fine women."

Harry turned on his heel and began to walk away. Nope, he doesn't know this man. As he turned to leave however, Azazel got up and walked next to him.

Harry didn't mind the man's perverted demeanor but the Fallen Governor really need to learn where to draw the line. Harry believed that married women should be off limits. In fact, if Harry knew Azazel wouldn't really try to go after his wife, he would have punished Azazel more severely than he would have when he attempted to flirt with Yasaka.

It was still the worst punishment Azazel had ever had. He had been cursed with erectile dysfunction and stripped of his powers for a month. It was one of the most humbling experiences in the Fallen Governor's life. His angelic powers had been completely gone, not just inaccessible. For a month, Azazel was just a normal, middle-aged human with a bad case of erectile dysfunction.

To a fallen angel known for his lust and perversion, it was pure torture.

"So I just thought you'd like to know. I heard that devils are going to try to establish a territory in this area soon. They probably didn't get the memo that this city was already yours." Azazel began conversationally.

Harry's expression was unconcerned. If any devils try to make moves in his domain, he knew he could take care of them no problem. He had specifically made it clear to all factions that this city was his. Normally, he wouldn't bother with such a thing. However, he wanted his daughter to experience interacting with the mundane world and as such wanted her to go through human schooling when she was old enough. As a city built on the nexus of four leylines, Kuoh was the perfect place for youkai to feel a connection to their home in Kyoto even in a city as developed as this one.

"Why don't you just tell them then?" Harry asked.

"Well, about that…If someone as important as me suddenly contacts people from the other factions, then that will surely set off alarm bells in their head no?"

For all Azazel's faults, he at least takes his job as leader of the Fallen somewhat seriously. The rest of the time, he was usually experimenting or going after women. Most of the time though, Azazel was a cool guy and easy to talk to. Hmm…was it his friend deprivation from his childhood that allows him to tolerate even the worst sides of people? He had put up with Ron's jealous streak for years after all.

With a sigh, Harry chose to resolve the situation before it started. If he waits until later to have this confrontation, misunderstandings and problems will surely arose between the involved parties.

"So who are these devils then?" Harry asked Azazel as he stopped walking. Noting the tone of Harry's voice, Azazel quickly answered. He knew Harry long enough that he meant to take action immediately.

"The Sitri and the Gremory."

Harry raised an eyebrow.

"And they think they can just walk in here and ignore my warnings without consequences?" Harry asked incredulously.

Azazel scratched his head. "Well, there are many in this world that believe themselves so far above humans that they could do whatever they want. You might have the title of Magic God, but you are still a human in the end. I bet they think the title is just for show. Hell, even I thought you weren't that strong until after you turned me into a human and cursed me with a month of no sex." It really says something about Azazel's character that he was more upset about not having sex rather than turning into a human.

Harry frowned. It was true that the title of Magic God was subject to relativity. In the end, all the title refers to was that a magician has mastered magic and can bend all things in the world without any exception through magic, transcending normal magic and stepping into the domain of gods. There were of course many ways to achieve this and their power levels were subject to how they obtained their ability.

Looking at it this way, it would make sense that people would be skeptical of Harry's claim to the title of Magic God. After all, mastering magic would normally take centuries and Harry looked to be in his mid-twenties. He also did not exude a large magical presence that would be typical of the reserves of a Magic God, reserves thought to be on par with gods themselves. If anything, his reserves were of normal wizards.

"I see…I guess a talk with them is in order then." Harry's eyes flashed as Azazel stared at him curiously.

"And do you expect them to drop whatever they're doing just to meet with you?" Azazel asked incredulously.

"Well, that just means I have to give them no choice, correct? I'm sure I can pluck them from wherever they are and force them to talk." Harry replied with a smirk.

Azazel stared at him for a second before barking out a laugh. Harry really was very interesting to be around. Only he would so casually make a comment to kidnap half of the leaders of the Underworld and have the power to actually back it up.

This, Azazel has to see.

4.

Harry and Azazel entered the pet shop and looked around the various animals in their cages.

Looking through various aisles, they found fishes, snakes, and turtles. There were even many different species of birds.

There was one thing that the pet shop was lacking.

They were lacking in rabbits.

Or any other cute, furry, animal for that matter.

Feeling a bit of trepidation, Harry asked an attendant where he could find rabbits.

The young woman smiled nervously at Harry's intense stare.

"Uhm… sorry sir. We are all sold out. It's been a very busy week. Just the other day, someone purchased all our rabbits in one go, our hamsters too."

Harry fell to his knees at this revelation.

"No…rabbits?" He muttered weakly.

Azazel rubbed his stubble in thought.

"Hmm, that's strange. I'm pretty sure there was still one left after I bought twenty of them yesterday."

Harry's head slowly swiveled towards Azazel, his eyes shadowed by his hair. An ominous aura wafted off him, making Azazel step back nervously.

"You…"

Azazel chucked awkwardly and discretely began to run away.

"IT WAS YOU, YOU BASTARD!"

Azazel's swift retreat was cut short as Harry slammed into him from behind, tackling him to the ground. His face was immediately pummeled into paste by the irate father.

"APOLOGIZE TO MY DAUGHTER!"

"ACK!"

5.

Thirty minutes later, Harry and Azazel were sitting on the curb. The fallen angel's face was black and blue, sporting bumps in places. His eyes were swollen and a tooth hung precariously from his gums. The store clerk had immediately called for security once the violence began. As a result, they were thrown out and forever banned from the store.

"I blame you for this." Harry grit out, depressed that he couldn't fulfill his daughter's wishes when he got home.

"Eeash 'ot mfff olt."

"What the hell were you doing with all those rabbits in the first place?" Harry demanded.

Azazel snapped his nose back into place and blew out the blood in his sinuses. Feeling somewhat better, he adopted a smug look and puffed his chest out proudly.

"I'll have you know, I've finally made a breakthrough with my research!"

At Harry's raised eyebrow, Azazel elaborated.

"Huhu. Feast your gaze upon this!" And with that, the fallen angel whipped out a white rabbit from inside his jacket. Harry looked at it curiously. Although it was moving its eyes and head, Harry could detect no life in it.

"What is it?"

"This, my ignorant friend, is a fusion of magic, cyborg technology, and the Sacred Gear Vorpal Blade! I, the super genius Azazel-sama, have recreated the Killer Rabbit of Caerbannog!"

Harry took the cyborg rabbit from Azazel's hand, a legendary rabbit said to have almost singlehandedly cut short King Arthur's quest for the Holy Grail. It was said to be able to kill fully trained knights wielding holy swords with the utmost ease. It truly was a potent weapon, especially against agents of the church. Harry raised it to eye level…

… and promptly smashed it into the ground.

The look of horror on Azazel's face was priceless.

"NOOOOO! MY LIFE'S WORK! GONE! DO YOU KNOW WHAT YOU'VE DONE?!"

Harry merely smirked back unrepentantly.

"I will not give my daughter such a manly pet."

Azazel grabbed Harry by the shirt and shook him furiously.

"Can't you just create a rabbit, yourself, you bastard?! You have god-like powers remember?!"

"Oh, I forgot about that."

Azazel sweatdropped and gathered the broken pieces of his invention into his arms, cradling it as if it was his child.

"Don't worry, Mr. Monty. Papa will put you back together…"

Harry tuned out the creepy mutterings and closed his eyes.

Harry's perception slowed to a halt as he found himself in a space that is void of time and meaning. For all intents and purposes, time had stopped outside of this space and the world was frozen in time. With a thought, Harry summoned a terminal.

Logging in.

Administrative privileges granted.

Accessing the Akashic Records.

Database ready for editing.

A multitude of information flashed through Harry's eyes and he quickly isolated the information he wanted.

In this place, he was God, free to control everything within the realm of existence.

In his home universe, the first time he accessed this place, the guardians banished him from the universe with brutal efficiency. Apparently, it was a crime for a human to have access to this kind of power.

Fortunately, this world's Root of All Existence had no such protectors.

After creating a new entry, Harry had successfully introduced a rabbit into existence.

It was a pure white rabbit, with red eyes and soft fur. All in all, it was no different from a normal rabbit. Unlike transfigured or conjured animals, those that are registered as a valid entity into the Records are legitimate beings and will not disappear after the magic holding their forms run out.

The universe acknowledges the presence of the rabbit in Harry's grasp and thus welcomes its existence.

A frown made its way into his face.

"What's wrong? It looks fine to me…" Azazel had finally stopped sobbing over his destroyed creation and looked at the rabbit in Harry's hand.

"Nothing's wrong… it's just…doing this kinda diminishes the meaning of the gift you know?"

Azazel nodded his head in understanding. It really would be pointless. It would be like plucking out your armpit hair and giving it as a gift. It takes that same amount of effort for Harry to do what he did.

With a sigh, Harry let the rabbit run off into the wild and looked up towards the sky, trying to think of a solution to his dilemma.

His gaze fell on a black cat lazing on a tree branch above him.

A smile lit Harry's face as a plan formed in his head.

6.

A black cat lazed on a tree branch.

This was not a normal cat. It was of the race Nekomata, subspecies Nekoshou. It was one of the most powerful races of youkai in the world, with the potential to reach Ultimate Class.

It was currently in cat form to suppress its magical signature and hide from its pursuers after killing its former master.

This was the Stray Cat Kuroka.

She saw two men enter a pet shop across the street and after creating a commotion, exited with despondent expressions. Kuroka watched their antics with amusement. Then the black haired one created a rabbit out of nothing. There was no surge of magic, nothing that would indicate that magic was used at all. Kuroka's eyes widened at the phenomenon. He then caught her eye and she stared back. A grin suddenly formed on his face that sent chills down the Nekoshou's back.

"Hmm… it might not be a rabbit but…"

All of a sudden, Kuroka found herself in the arms of the green eyed man. His grip on her ensured that she didn't escape his grasp.

"A cat is fine too."

"NYAA?!"

Chapter End

A/N: And so it ended with a meme.

Thank you for reading.

While Harry is OP, he will not just mercilessly kill everyone that upsets him. He's not heartless. He doesn't have a god complex.

The point of this fic is not to curb stomp everyone, although Harry will retaliate with enough force to those who attack him or his family. This makes my job as a writer harder since I have to write a story that is interesting even though there literally is no one who can pose a challenge to the main character. This is hard but not impossible (see "The (questionable) Burdens of Leadership of a Troll Emperor" by noodlehammer). I only hope I can make a story even half as interesting.

Good? Bad? Not worth continuing? Please leave a response on your way out.

And one again, thank you for reading.
