AN: This is set in a slight AU following the manga's Thousand Year Blood War arc.

I do not own Bleach or Harry Potter the both belong respectively to Tite Kubo and J.K. Rowling

Soul Reapers: spiritual guardians of the World of the Living. Their job is to maintain the balance between the myriad of good and evil souls that fill this world.

In his battle against the newly revived Voldemort; Harry lost his connection with Nakatsukasa along with the destruction of his combat pass and subsequently his mother's protection.

While Dumbledore began making plans to combat the Dark Lord, Harry decided set out on his own mission. Traveling to the Urahara Shop in Karakura Town, he sought out Kisuke Urahara for the means to restore his Soul Reaper powers. Upon his arrival Harry was surprised to meet the legendary Substitute Soul Reaper: Ichigo Kurosaki and his twin children Sora and Masaki.

Agreeing to help Urahara brought them to his secret subterranean training ground, where he had a question for Harry.

"There's something we have to talk about before that" said Urahara. "Tell me, Harry, have you ever heard the term, Horcrux?"

"Horcrux?" Harry repeated. "No. what is it?"

Suddenly there was a change in Urahara, gone was the playful and mischievous candy shop owner, replaced by a hardened and knowledgeable captain class Soul Reaper. Noticing the change in his friend, Ichigo directed his children away not wanting to expose them too much to the darker side of the spirit world.

"A Horcrux, Harry is an abomination" said the former Squad 12 captain. "It's a wizarding attempt to achieve immortality. They describe it as fragmenting the user's soul and sealing it away in an object for protection – believing that if the fragment is safe then they can't truly die."

"Can you actually split your soul like that?" Harry asked, finding the idea disgusting.

"It is possible" said Urahara. "The ritual to create a Horcrux breaks down the soul's cohesion allowing it to be split apart. But what the wizards don't know is that these soul fragments also maintain small links of their chain of fate. These chain links bind the soul fragment to the object creating a Horcrux."

"Sounds a lot like a normal Bound Spirit" Ichigo commented, returning after leaving his children in Yoruichi's care back in the shop.

"You're not wrong, Ichigo" said Kisuke. "Like a Bound Spirit the soul fragments' chain links will eventually erode. However, the Horcrux's spiritual pressure is far more unstable and more often than not will lead to a Soul Suicide. In order to try and avoid this the soul fragment will attempt to Hollowfy in order to strengthen itself."

"Voldemort must've made a Horcrux" Harry realized. It made sense considering the Dark Lord's recently acquired ability to summon Hollows and even fire a Cero.

"I'd say several based on how unstable his soul is." Urahara confirmed.

"The diary" the younger Substitute Soul Reaper muttered, remembering that day in the Chamber of Secrets that set him on this path. It had to have been a Horcrux.

"What diary?" asked Ichigo, confused as to what a harmless book had to do with anything.

"I'm sure Harry can explain the details later" said Urahara. "As this information is obscure even in the Soul Society, I don't blame Rukia for not recognizing it."

"Ok but what does all this have to do with restoring Harry's powers?" asked the orange haired Substitute Soul Reaper. "We could've gone over this later."

Harry was starting to suspect what Urahara was getting at. Why would he bring up the subject of Horcruxes if it wasn't relevant? Then he remembered what Dumbledore had told him about his ability to speak parseltongue: "Unless I'm mistaken the night Voldemort attacked your family, he transferred some of his power to you" It could only mean one thing.

"I'm a Horcrux, aren't I?" it made sense. It also explained his ability to speak to snakes and the random moments when he'd start to Hollowfy.

"Yes" Kisuke said grimly. "I've identified you as a Horcrux. The fact that your zanpakutō hasn't repaired itself was a major clue." Noticing Harry's confusion, he decided to explain. "As you know a zanpakutō is a part of their owner's soul, as such they cannot be replaced. Under normal circumstances any damage done to a zanpakutō's shikai would be repaired over time with exposure to the Soul Reaper's spirit energy.

However, in a living vessel the Horcrux acts like a parasite – slowly infecting and feeding on its host from within. We can assume this soul fragment had attached itself to you when Voldemort attacked your family thirteen years ago. Since then it would've slowly been infecting your soul, not even Nakatsukasa would've noticed given how long it'd been hidden inside you."

"Ok, so is it like an inner Hollow?" asked Ichigo. Having already guessed Harry has had a rough time of things, he didn't want to add to that list.

"Similar but not quite" said Urahara. "The difference being that unlike with an inner Hollow, the Horcrux can still be removed from the host soul. If not for the protection left by Harry's mother the Horcrux would've corrupted his soul long ago. But with Voldemort growing in power and with Lily's protection gone; the Horcrux has grown powerful enough to damage Harry's connection with his zanpakutō."

At least the seal on my chest makes sense now Harry thought to himself. The Horcrux couldn't feed on him if his spirit energy was under lock and key. "So how do I get rid of it?" he asked Kisuke.

"There's only one option" he replied. "You'll have to purge it from your soul. The Horcrux isn't going to be hiding now and it's going to put up a fight."

"I don't care" Harry hadn't come all this way to give up now.

Ichigo gave the younger Substitute Soul Reaper an approving look. Urahara simply smirked as he remembered the countless times the orange haired man had – had that very same look of determination in his eyes.

"Let's get started" said Kisuke. Before Harry even knew what was happening the shop owner jabbed him with the end of his cane, pushing the boy's soul out of his human body.

While annoyed by the sudden act, Harry was equally relieved that his spirit form was still that of a Soul Reaper. The sight of the still broken hilt of his zanpakutō filled him with resolve to restore his link with Nakatsukasa.

Harry was about to ask what came next when in a burst of speed Urahara was directly in front of him, holding his palm over Harry's face, a white light emanating from his hand. Next thing he knew the world went dark as Harry fell to the ground unconscious.

With that out of the way, Kisuke called Tessai over to join them. The employee then picked up the unconscious Harry and carried him out into the center of the open field.

"I thought this wasn't going to be like with the Vizords" said Ichigo, watching as Tessai started to put up barriers around Harry.

"I said it's going to put up a fight" said Kisuke.

Understanding where this was going, Ichigo took his own combat pass and pressed it against his chest, releasing his Soul Reaper form. Like Harry and most other Soul Reapers, Ichigo wore the standard black shihakushō, but with some personal changes: two white shoulder plates extended over his chest in an X shape, with his left shoulder plate adorned with three sections of red scales, and a white cloak with black marking tied around his waist.

His zanpakutō: Zangetsu, two pure black blades were strapped to his back and right hip. The blade on his back took the shape of large khyber knife, with a thin hollowed-out portion running along the back edge of the blade from base to the middle of the blade. While the smaller blade on his, resembled a trench knife with an enclosed handle, with a portion acting like a hand guard.

"So it's my job to keep him under control" said Ichigo, walking up to the barrier.

"Exactly right" Urahara said a little too cheerfully, earning himself an elbow to the face. "Ugh, you know I take back what I said about you and parenthood" he cried, as he kneeled over, holding his hands over his injured nose.

"Whatever you shouldn't sound so damn cheerful about this stuff" the orange haired Soul Reaper scowled. "And enough with the fake crying!"

Dropping the act Urahara stood up – no sign of tears in sight – and snapped his fingers. At once the intricate seal over Harry's chest dissolved off his body.

"Tessai open the barrier" he instructed.

"Not that I'm doubting Tessai" said Ichigo. "But wouldn't Hachi be better for the job?"

"I admit Hachigen is very skilled in kidō especially barriers" said Urahara. "But who do you think he learned it from?"

It was easy to forget that Tessai himself was also a master of kidō and even served as captain of the Kido Corp before his exile from the Soul Society. Ichigo didn't say anymore and entered the barrier with Tessai closing it up behind him.

"You two can come out now" Kisuke called out, prompting Sora and Masaki to poke their heads out from where they were hiding behind a boulder.

"We felt Daddy's spiritual pressure" Masaki explained.

"We almost never get to see Dad fight" said Sora.

Kisuke shook his head in amusement at the fact that even after all this time Ichigo still wasn't that good at sensing spiritual pressures. Seemed that was one area where Harry surpassed his predecessor.

Trusting that Tessai's skills would be enough for the task, Kisuke allowed the Kurosaki twins to stay and watch.

Alright Harry, let's see what you can do.

Entering his inner world, Harry was relieved to see that the damage to his sword was limited to the outside world. That was quickly brushed aside once he took stock of just how much damage the Horcrux had done to his inner world. The once tranquil lake had completely frozen over and the night sky decorated with stars that represented his hopes and dreams, had been replaced by a blood red sky.

And waiting for him standing with its back to him, on the lake's frozen surface – in a set of white wizard robes – was what Harry could only assume was the Horcrux.

"So you've come for me" the Horcrux spoke, it's voice sounding like a distorted echo.

"Where is Nakatsukasa?" Harry demanded, unable find any sign of his zanpakutō spirit or her spiritual pressure.

Harry's eyes widened as the Horcrux turned to face him, wearing a face very similar to his own. Like Harry, the Horcrux had messy black hair and green eyes, and while their faces were similar there were some differences. The Horcrux was incredibly pale skinned with teal lines running down from below its eyes. The very same eyes though green were much darker then Harry's own and had the typical Hollow black sclera. On the top-left side of its head, was what looked like part of Hollow mask forming a broken horned helmet.

If the Horcrux's appearance of a Hollow version of himself wasn't bad enough, sickening chills ran down Harry's spine as the soul fragments mannerisms were very much the same as the Tom Riddle he had faced in the Chamber of Secrets.

"I'm afraid, I've devoured your little bird" the Horcrux taunted.

"Then, I'll just have to cut her out of you" Harry said determinedly, his anger rising.

With a sadistic smirk on its face the Horcrux opened its right hand, letting a rusted twisted version of Nakatsukasa's blade appear in its hand. Then in a burst of speed the Horcrux leapt into the air, bringing the twisted version of his zanpakutō down on Harry.

Relying on his quick reflexes, Harry brought up his own sword just in time to block the majority of the Horcrux's attack as the weight of its power started to crack the ice beneath him.

"It's funny how you think you stand even the slightest chance of that."
