AN: Curse whoever thought of crossovers between Harry Potter and Katekyo Hitman Reborn! They seem to have taken control of my brain! Why must there be so many ideas floating around in my mind? Sometimes I really hate my muse... Anyway, I hope you enjoy this new story!

Chapter One

Lily Potter felt disgusted.

There were too many people to direct that feeling to: Dumbledore for delaying the war so long with his pacifist tendencies, James for believing a stupid prophecy that probably hadn't been real in the first place, Peter for betraying them after being James's friend for so many years, Voldemort for starting this ridiculous, pointless war at all, or herself for what she was about to do.

She wasn't known as the smartest witch of her generation for nothing; like Dumbledore with Transfiguration, Nicholas Flamel with Alchemy, and Voldemort with Dark/Necromancy magic, Lily pushed herself to be the best in her field(s) of expertise, which was Charms and Rituals.

Ever since they'd gotten the news that Voldemort was targeting Harry, Lily had been researching any Charms or Rituals that could help their son should the Dark Lord find them. Lily had nearly given James a panic attack or nervous breakdown with how hard she pushed herself, but Lily had found not just one, but two Ancient Rituals that might be their salvation.

The first was simple; put Runes, drawn in her blood, in a specific order around the child in need of protection (Harry, in this case), and the sacrifice of both the mother and father out of love would cast a life-long protection against the attacker. Voldemort wouldn't be able to touch her baby!

At first that was going to be the ritual she'd use, but then after researching a little bit more, Lily had found a second option. This ritual was similar to the first one up to a point: it used runes and the sacrifice of both parents out of love, but it did more. It eradicated the enemy, completely and utterly, but to add a steeper price to such a powerful feat of magic, the child would lose their magic. It would be as if they had never had a magical core at all. The child would then be taken, by the spirit/consciousness of Magic itself, to a family that needed him/her, and become that family's child, in blood and soul.

Lily had been horrified at first, when she had first discovered the ritual, but after thinking it over and trying to dissect it, the new mother thought she knew why such a ritual had been created in the first place.

If a madman like Voldemort wiped out an entire Wizarding Family, like James's, the Prewitts, and the McKinneys (meaning that there were no male heirs left), this ritual would ensure the eradication of the threat and the survival of the family line, if not the name. The child might be rendered magicless and released into the non-magical world, but one of their descendants would likely regain the gift of Magic and rebuild their House from its ashes, like the mythical Phoenix. Add the fact that most Witches and Wizards didn't know how to navigate the mundane world now and that child could vanish quite completely, destroying any chance of assassination.

Ultimately, the second ritual was what Lily decided to use should Voldemort find them.

"Harry, be safe. Be strong. I love you so much, my son," Lily choked out. Tears pricked at the corners of her shining emerald eyes, but the fiery mother refused to let them fall. The so-called Dark Lord would not see her weep. Harry looked at her with eyes the same shape and color as her own.

But the tender moment between mother and son was cut short when the door to the nursery was blasted open. Lily at once got to her feet and spun to face Voldemort, spreading her arms wide.

"Step aside," the Dark Lord hissed coldly. The Yew Wand that had helped cause such destruction, despair, and death was brandished threateningly, but Lily held firm. For Harry, always for Harry, my life willingly given for my precious son-

"Not Harry, please not Harry, take me-"

"Step aside! Stand aside, you foolish girl!"

"No, not my son; please, have mercy, take me instead-!"

Voldemort's crimson eyes flashed bright in rage, and without a moment's hesitation the Killing Curse was fired at the defiant young woman. Lily stood her ground, and even though instantly killed, she died without a sound, without tears, with a small smile on her lips. For she knew that in her death and sacrifice, she had won. This would truly be the night Voldemort was defeated.

With a disdainful sneer on his snake-thin lips, Voldemort then turned to the small child prophesied to destroy him. Raven locks were as messy as his father's had been, but with the mudblood's emerald eyes and pale skin.

"With your death, my victory is assured. You should be honored," the Dark Lord almost whispered. And then he spoke his most beloved spell, satisfaction gleaming in his inhuman eyes as the green spell flew towards his enemy.

But the runes, drawn by Lily earlier that week and activated by Lily and James's sacrifice not ten minutes earlier, flashed as the Killing curse neared the babe. The spell shuddered to a halt in midair, hovering as the ritual went underway. The child's magic was extracted, every last bit of it, until Harry Potter was nothing more than a Muggle; his magic, as well as the ritual's and his parents', was added to the Killing Curse until it became the perfect agent of annihilation.

All this had taken less than a second, and as Voldemort gaped, his own transformed spell flew towards him. The spell struck, shredding the Dark Lord's body, mind, and magic into nothing. His soul (maimed as it was) remained, though not for long. Across the country, various objects rattled and wailed as the soul fragments they housed were extracted, leaving the objects undamaged. The soul rejoined until it was whole once more, and then it was sent to eternal punishment where it belonged.

Silence fell in the little nursery, only broken by little Harry's soft cries. And then Magic itself appeared in the room. Magic had no set form, but now it appeared as a young woman with soft brown hair cut Egyptian style and gentle golden eyes. She picked up the small child and cradled him in her eyes. Her skin glowed softly, giving away the fact that she was not human.

"Oh, my Child," she murmured sadly. "I weep for the destruction and heartache Tom Riddle spread; but thanks to your mother and father, his reign of terror is now ended." She soothingly stroked his hair. "Your Magic is gone, little one, but you will gain an equal gift." With that, Magic disappeared from England entirely.

"Namimori, Japan," Magic said, looking at the baby in her arms. "You will become part of the Hibari family, little one; their son is meant for great things." The little child was placed gently on the doorstep, features already changing to match those of the family that would now be his own. His hair was still as black as ebony but his eyes changed their color and shape: emerald green turned to silvery-gray and they were narrow. The rest of his features changed until he looked more Asian. Where his magic once resided was now home to vivid purple Flames that curled around and in his soul before settling. Magic gave a small smile and placed some strong charms on the baby: no one of ill-intent would be able to harm Harry, and he would be protected from the elements.

And then Magic placed two letters beside the child, settling them among the blankets. One was from Lily Potter, written soon after she had prepared the ritual, explaining everything. She explained that her son would no longer have magic, and would be placed by the personification of that magic to a new family. 'Please... take care of my son,' she'd written. 'Whether you tell him or no is up to you, but if you eventually tell him... tell him that James and I loved him.' The other letter was from Magic, explaining her reasoning for choosing the Hibari family. She also cleared up any confusion that the new parents might have about Lily's letter.

"Your former family's fortune and properties will be held in stasis until claimed by a legitimate heir with my gift," Magic said softly. "Neither thief nor fan nor manipulator will be able to lay a hand on anything. This I swear, Lily and James Potter." Magic faded away, knowing that its duty was done. One of its favored children would be safe and he would also have a very...interesting future.

Hibari Kohaku sat in her house with a baby nestled in her lap, cooing to him softly as her husband examined the two letters she'd already read. There was a small, thoughtful frown on his usually-impassive face. The little boy blinked up at her with the Hibari clan's eyes, even though no new children had been born recently, which helped prove the claims in the two letters, Kohaku thought.

Finally, Noritaka set the papers down. "So... we are to raise him."

"Yes," Kohaku said. "I doubt that this was written with deceit or treachery; call it a mother's intuition, but Lily Potter sounded too desperate and scared to lie. And what do you think?"

Noritaka was silent for a few moments, eyes narrowed slightly more than usual as he thought. Then he gently lifted the little one from his wife's lap, settling the baby on his own. The Hibari clan head and the one-year old stared at each other, until Noritaka sighed. "This little one's been through so much already in such a short time," he rumbled. "It would be cruel to leave a young one alone now." Not to mention the fact that Kohaku was already attached to the small animal, he thought wryly. Short of death, nothing would change her mind.

Kohaku beamed, taking their son up in her arms. She already had the perfect name for their new son. "Welcome to our family, Hibari Kyoya."

How'd you guys like? Oh, little note: Kohaku apparently means 'Amber', which I thought was kind of funny. In other Harry Potter/Katekyo Hitman Reborn! crossovers, the Sky Flame is sometimes called the Amber Aspect, so that's a little nod to some trivia. Does that mean that Hibari's mother was a Sky? Don't know. And Noritaka, Hibari's father's name, apparently means 'commandment and devoted virtue' (according to the site I used), so that helps give some traits of Kyoya's father.

I hope I explained the ritual Lily used well; if you have any questions, give me a review or PM me. I wanted Harry to truly BE Hibari Kyoya, but I didn't want reincarnation or one of the Potters to be unfaithful to be the reason. I already have the pairing for Kyoya decided, but romance is not going to be the focus of this story.

See you next chapter!
