Hidan and Kakuzu raise harry potter idea

Here's the summary of the idea,

Kakuzu slips off one of his hearts during the edo tensei attaches himself to another body.
The body is small so he goes back to where Hidan's buried and digs him up.
Hidan is more crazy then usual but is really grateful to Kakuzu for rescuing him though he'll never ever admit it. They start traveling together with the though they'd split after Kakuzu find another body. Only once Kakuzu finds said body they'd become to dependent on each others ability to stop their nightmares to separate. Though they insist that its only because its more beneficial to stay together then to split. So they stick together. Eventually they fall beck into their original rhythm of bounty hunting with the occasional off course religious fiasco.

Mean while 5 or 6 year old harry is locked in a cupboard and wishing. He wishes for 3 things.
-To be away from the Dursleys
-To find someone who will protect him forever and not die on him like his parents.
-To become strong enough to defend himself and deal with his pain
His magic grants his wishes

Hidan and Kakuzu are camping out after a successful bounty-hunt. Hidan is complaining about Kakuzu being a boring, stingy atheist and begins preying to Jashin-sama for something to do. A sign of what task Jashin will set for him so he can do something other then "Fucking shit ass annoying repetitive bounty hunts."

Thus just as Kakuzu is about to decapitate Hidan one very bruised but rapidly healing Harry potter falls into Hidan's lap. Literally. Hidan of course ,after getting over his shock, takes this as a sign from Jashin. This obviously powerful child, it just teleported if loudly and has apparent healing powers, must be a potential follower of Jashin. What's more entertaining then an apprentice?
Kakuzu of course doesn't see it this way and starts musing on ways to sell Harry. Hidan chucks a massive fit and swears that if Kakuzu tries to remove Jashin's newest follower from Hidan then Hidan will annoy Kakuzu for the rest of his immortal existence. Kakuzu reluctantly agrees to let Hidan keep the 'spawn' as long as he takes care of it himself, finds a place for it on bounty hunts and keeps it far far away from Kakuzu.

Hidan of course performs the immortality justsu on harry. Which works. Which Hidan takes of confirmation of Jashin's desires. Thus Hidan begins to teach harry the religion of Jashin. Only one problem...Hidan and Harry speak different languages. Also Kakuzu is now stuck with two immortal children and is basically thinking FML.

Harry begins to quickly pick up the language and the shinobi arts that are taught to him. Harry as per his time at the Dursleys tries to make himself useful and thus cooks and cleans whenever he can. He also tries as hard as he can to learn from both Hidan and Kakuzu. Though only Hidan pays consistent attention to him Kakuzu tends to ignores him. Hidan tries his best to fulfill Jashin-sama's wishes and turn the malleable harry into a devout follower of Jashin. Kakuzu however sabotages his efforts whenever possible "I'm already stuck with one loud, stupid, reckless arrogant immortal child I'm not dealing with another." Also it pisses Hidan off.

Kakuzu only begin to take interest in harry when harry has his first bout of accidental magic stopping a storm of kunai and launching them back at his opponent. A talent which looks remarkably similar to the deva path of the Rinnegan . But as they come to discover the power that harry used is not in fact chakra. Making Kakuzu interested and Hidan thrilled. So Kakuzu begins trying to find out what it is and find ways to make that power useful for money making. Also has the side effect of Kakuzu trying to sway harry to the lure and dependability of money. After all the more harry cares about money the less things that Kakuzu has to pay for.

So harry grows up being dragged around the elemental nations by two high class criminals after bounties and religious quests. He never stays in one place long and most of his time is spent camping outside or in really cheap hotels. He is taught that violence is completely fine and expected. That pain in all of its forms are beautiful and are to be shared. He learns that might controls everything and without strength he cannot protect anything let alone himself.

At first this is distressing to harry after his time with the Dursleys. He is scared of the violence and the completely opposing expectations. He is no longer a 'freak' among 'normal' people. But then the ones who picked him up are freaks too so maybe this is just how things are around his 'own kind'. He kind of understands why his 'family' were so scared of the freaks after all Hidan-shisho and Kakuzu-sama are scary people. But that's ok because their teaching him how to be scary too. The better he gets at fighting and killing the more useful he is to them. Harry also gets used as bait occasionally during their various bounty hunts. Thus leading to more accidental magic.

Under Hidan's teachings harry grows to accept and even enjoy the pain he once hated and feared. Though Kakuzu makes sure to curb his more reckless tendencies. Its hard enough making sure Hidan doesn't do anything too stupid. This of course leads to many fights between Kakuzu and Hidan.
Eventually harry comes to perceive certain forms of violence as a kind of affectionate communication.
Hidan attacks Kakuzu to get his attention and Kakuzu 'kills' Hidan to try to curb his recklessness and keep him out of trouble. Basically violence whether physical or verbal is how they show they care.
"Pain is Jashin-sama's great gift to the world. It connects all people, affects all classes and all ages. It warns of death and it is though pain that we become stronger. This is the nature of Jashin-sama's gift."

Thus leading harry to begin to question his time at the Dursleys. Was Vernon an abusive ass that deserved a slow death or was he just trying to connect to harry though pain in the way of Jashin-sama and harry had just been too young to realize it? So Harry 'savior' of the wizarding world grows up in a world of blood, pain,corpses, swearing, religion, money and copious amounts of violence. Hogwarts won't know what hit it.

Bonus points for manipulative!Dumbledore. Not evil!Dumbledore and especially not stupid!Dumbledore. Fics where Dumbledore reveals himself too early by stealing Harry's money or sealing his magic while fun often leave Dumbledore with a relationship resembling Snapes one with harry. The brilliance of Dumbledore in the books is that his manipulation was subtle. I'd prefer a Dumbledore that while not evil, certainly disprove of Harry's current guardians and living conditions and is not adverse to using his admittedly vast political power in order to pull a few strings.

Chakra and magic. Chakra is made by mixing physical and spiritual energy inside ones body and then releasing it in the form of jutsu. To use it require both mental power and physical strength. Magic is purely spiritual energy which while not requiring it, is enhanced by having a focus especially one of already magical nature, such as a wand. As such to use magic only requires mental strength.
To compare the two is like to compare water (magic) to ink (chakra). Charkra is denser and thicker then magic and is as such more powerful. If an equal amount of raw chakra and raw magic collided the chakra would win if barely. However magic is more flexible and thus capable of a greater variety of effects.
For example: Chakra will never be as strong as pure physical energy like whats seen in say DBZ. (physical energy being the hypothetical ink powder). However the physical energy in DBZ while destructive is not elemental nor could it summon animals, craft illusions or make seals. In a similar way chakra while powerful cannot be used to transfigure a rat into a goblet, turn a cup into a portkey or make a broom fly.

Anyway that's the base of my idea. I look forward to seeing what you can come up with. If you feel like doing this idea just PM me the link and have at. Good luck.
