"Again!"

The sound of chirping birds filled the air as lightning chakra burst from my fingertips as a white mass of sparkling electricity.

Until it fizzled out rather anticlimactically, that is.

"Again!"

Kami, Kakashi is a slave driver. While my teammates were being drilled in Taijutsu and weapon slinging by one of Kakashi's shadow clones, I was being taught the Chidori.

"Again!"

And fucking hell is it frustrating.

I've been at this for weeks now, and I had failed to maintain the Chidori for more than a few seconds. I've been training for the Chidori for a month and two weeks to be exact. I didn't have time. The Chunin exams was in two weeks! I'm going to freaking die without a good jutsu to defend myself in short range combat.

Sasuke had to train with it for a month before the Chunin exams tournament. And that was with the bullfuckery that was the Sharingan, so I guess I shouldn't be too surprised that I wasn't picking it up as quickly. I was hoping that, with my chakra control that had been praised by all of the Academy teachers, I would be able to learn the Chidori quickly.

"Again!"

No such luck. Clearly either the Academy had extraordinarily low standards, or the Chidori is just that hard. Probably a combination of both.

"Again!"

At least chakra exhaustion probably won't be an issue for me. I had created countless sort of Chidoris, and I hadn't even felt my reserves dip at all. I'm making steady, if slow, progress with the countless Chidori's I can pump out on a regular basis. Although now that I think about it, the only reason that I wasn't feeling the drain with the countless Chidori's I'm making is because I'm making them improperly. Kakashi told me I'm not focusing my chakra enough, so I guess that means I not putting enough in and compressing it enough for anything to happen.

"Again!"

Now that I think about it, I've never felt chakra exhaustion, only the pain in my chest. Speaking of that pain, I really have to get that checked out some time. It's not like it's that difficult to arrange a check-up, it's just that I keep forgetting.

"Again!"

My forgetting to arrange a check-up is probably due to me not exactly caring about the pains. I am slightly concerned about the pains, but they haven't really gotten worse over time, so…

"Again!"

The pain does get worse when I'm using the Rat Tremor. I assume it gets worse after a more chakra-taxing jutsu, but that doesn't explain the strange absence of pain that I experienced when first learning the lightning hounds.

"Again!"

It'd really suck if the pain did get worse when using bigger jutsu. Then it would be really painful if I were using a jutsu that was hard on the reserves. I'd never get to use anything like Naruto's Rasenshuriken without feeling ridiculous amounts of pain.

"Again!"

With the Rat Tremor though, I'm not using it to its full capacity. Right now, I've gotten shakily up to three discs. The chest pains have steadily increased in intensity with the added discs. Will I ever be able to use the Rat Tremor at its full capacity?

"Again!"

Hopefully. You can be trained to ignore pain to an extent, so yeah…

"Again!"

Lightning formed in my hands, much more steadily than the other times. I looked downwards.

It was beautiful.

This time, my Chidori was much more solid. It formed easier, and just felt better overall.

I was aware of a small prickling sensation. At first, it felt just like any of my other chakra-associated pains, but it just didn't go away. The prickling grew as I fought to keep the Chidori stable. The pain throbbed painfully in my chest, ebbing and flowing with my heartbeat. It grew steadily.

Before I knew it, I was on the ground.

I was gasping for breath. The pain wasn't limited to my chest anymore, I felt it in my arms, my legs, through my eyes. It felt like a bucket of molten steel Kawarimi'd with my blood.

Blood.

Oh man, there was quite a bit of blood.

As in, I was painting the ground red.

The loud chirping and bright flashes of the Chidori only served to irritate my already aching ears and eye.

It was agony.

It was beautiful.


"Your chakra system is fucked up as hell." The doctor eloquently told me.

I was lying in a hospital bed, hooked up to various medical devices. I raised an eyebrow.

"Is there no better way you could have phrased that?"

"That was the most accurate way to describe it: fucked up. The only way it could possibly be more fucked up is if part of it were literally broken."

I breathed a sigh of relief. I still had a functioning chakra system.

"No, seriously! Not just your chakra system either! Your entire body is fucked up! Half of your organs have mechanical implants, and your right hand is chock full of mechanical bullcrap, complete with random artificial tenketsu!"

I still see no problem with this. It could have been worse, considering the fact that I was Orochimaru's plaything for six years.

"And get this: your chakra fucking regenerates with pain!"

Wut?

"I've never seen anything like it! For whatever fucking reason, your body pumps out more chakra when you're in pain! Any time you're missing any chakra at all, your body subconsciously mutilates itself to produce more! It's fucking insane!"

That's… crazy.

My body is like a giant well of chakra, with pain acting as a bucket to draw out the water.

I really am a Ninjutsu specialist. There would be literally no better way to focus that chakra potential than becoming a jutsu cannon. Even if I wanted to choose differently, the village would probably force me to become a NInjutsu guy.

That's probably why all the Jinchuurikis rely heavily on Ninjutsu in their fight. Or did the villages just brainwash everybody?

All of the famous people in the history texts are Ninjutsu cannons. They're famed for being able to cause ridiculous amounts of damage to the world. I guess children look at those guys, and think: I want to be like them.

They got me to. But jutsus are just so cool! Explosions solve everything!

In any case though, I guess I finally got my chakra pains checked out. It did make sense. The Chidori was draining as hell, so my body was breaking itself down to make more chakra. I've got to train myself to only fuck around with pain if I actually need chakra.

"And don't even get me started on your chakra itself! It just feels… like absolute shit! It's wrong. Like the Kyuubi's, but… not… quite… It's just, negative."

Did this follow the logic of anything in the Naruto series? Alright, so we're looking for magical chakra monster, that feels like negativity and can recharge on pain. I'm also guessing some sort of fast healing mechanism involved, since I recovered from my body literally mutilating itself to get enough chakra to stay topped off while using a Chidori.

So as far as bijuu are concerned, we've got Shukaku to Kurama. None of them have pain-related chakra regeneration. So our chakra monster probably isn't a bijuu. Unless it's a piece of the Juubi? I'm pretty sure that the Juubi doesn't work like that, but it's sort of got the regeneration covered? Besides, where would Orochimaru get a piece of the Juubi, or any of the Juubi's chakra from?

Nah, not the Juubi then. What other chakra monsters are there? Unless it's not a chakra monster that's the source of my powers?

Let's see, there was that Meteor thingy that Hoshigakure used, and it strengthened chakra at the risk of the user's body becoming damaged. The meteor would make sense, but it doesn't cover the healing factor, the pain-based chakra recharge, or the similarity to the Kyuubi's chakra.

There was that Box of Ultimate Bliss in Kusa, right? The one that turned you into the host for the giant bird-monkey demon thing, Satori? That strengthened your chakra, yeah? But still, it didn't cover the stuff that I apparently had.

"Hey! Are you listening to me? This is very important: you need to- "

"Yeah, yeah, doc, just do your thing." I carelessly waved off the doctor. I have more important things to think about.

So we're back to magic chakra animals. Did the Jiongu count as a chakra animal? I've always wondered whether it was like, a parasite or whatever, or a legit jutsu, that you could learn. 'Cause if you can learn the Jiongu…

Hoho, Kakuzu, you ain't got nothing on me.

Back on topic, chakra animals.

Wasn't there that weird-ass jutsu, the chimera technique? That one could fuse together animals. Was I the fusion of several animals? That could be it, maybe one of them could regenerate from pain?

Then there was that giant leech thing that those flying dudes used to power their big ass flying fortress, the Reibi. The one that could… regenerate when stuff was cut off… and generated chakra… from… negative emotions. Huh.

I think we have a winner.

Am I a chimera with the Reibi and myself acting as the ingredients? Maybe I'm just the top layer, and underneath the skin as a giant chakra… leech… thing. That's a slightly disturbing though, but whatever! Anything for power!

Pain isn't an emotion though? Whatever. It's a negative sensation, good enough to power my chakra, I guess.

Should I be freaking out?

Nah.

But I gotta figure out a way to better control how my body responds to lower amounts of chakra. I need to know exactly when I can expect the pain. If I go through so much pain that I pass out, then the increased chakra regeneration is useless.

"Hey!" The doctor slaps me this time, "Listen to me!"

There's no way that whatever he's about to say is more important than my thoughts, "The hell do you want?"

The doctor sighed in resignation, "You know what? Whatever. Just get out of here. Take it easy for the rest of the week. Not like you can move very well anyways."

"Sure, whatever." With that I hopped out of the hospital bed, opened the window, and dived right out of it, leaving behind a flabbergasted doctor.

Quick recovery for the win! That foolish mortal dared to doubt my regeneration!? Nevermind the fact that it probably came from a leech that may or may not be living inside of me. I can see why Jinchuurikis are so highly favoured in the Hidden Villages. If my recovery was any close to what Bijuus could gift to their containers, those guys were nigh unstoppable in combat.

I should treat Naruto to ramen more often, if only to have his help in combat when I indefinitely find myself fucked over in a fight.


"Alright, here's to confirming the Reibi actually is hanging around somewhere!" I said out loud to no one in particular. I was currently at Training Ground Seven, bouncing around in excitement. Hey, it isn't every day that you may or may not get a potential power up.

"Oh great Reibi!" I mockingly called out, "Hear my call, and get me that rock!"

Alright, enough screwing around. Time to actually get down to business-

Thunk!

Ow! The hell!

The rock bonked me in the head, in a way similar to Tora and the key from Orochimaru's lab. Wiping a bit of blood from my head, flowing from a wound that was already healing thanks to my healing factor, I decided to try again.

"Alright smartass," I snarled, presumably to the Reibi, "Hold the rock, and don't, don't throw it at me."

This time I actually saw it. It was still too fast for me to actually see the movement out of my body, but I saw it once it stopped and grabbed the rock.

It was a long, rubbery white arm extending out from my. I followed the arm up to see where it… holy crap!

No wonder it was hitting me in the face when I was grabbing things. The extra arm came from my freaking mouth! It was an extension of my Kami damn tongue!

This is concerning. And freaky as hell. Also cool. But mostly freaky as hell. And concerning.

I wonder if I can make more of-

"Will you cut that out!" I shouted suddenly. My voice was slightly muffled by the arm extending out my freaking mouth, but somehow I was still able to speak. I'll chalk it up to chakra shenanigans. At my sudden declaration, the stinging feeling that was slowly building in my chest as the arm stayed extended vanished.

Convenient. It seems to want to obey me. Presumably because my death would be a rather unpleasant experience for it. Wait, that implies sentience if it's obeying my orders. Can it talk to me? Maybe it'd be a good friend?

Admittedly, making my first friend in Naruto a few days ago has made me kind of hyped for my friends. Was the friendship going to my head? Oh Kami, I hope not. Most shinobi developed quirks as they grew stronger, for whatever reason. Would my quirk be becoming everyone's friend? Would I become like freaking Gai? Except instead of shouting about youth, I would shout about the magic of friendship. No. No, no, NO! This can't happen to me! Friendship is not magic! NO! NO-

Slap!

Aw, thanks creepy, rubbery, tongue-hand thing! Slapping me out of my tangents and stuff! Not only did it shut off the automatic pain-inducing thing that was going on, but it was turning out to be one of my best friends!

I will conveniently ignore the fact that, if the Reibi is, in fact, a friend, it will be one of my only two friends. Alongside Naruto.

This is slightly saddening.

Whatever! Back to training.

"Yo. Reibi. I'm gonna make the Chidori again. Do me a solid and don't cause me pain? I know you want to keep me topped off on chakra, but going to the hospital isn't exactly conducive to training."

I paused for a moment, trying to decide whether or not the Reibi heard me. Whatever. Not like a little bit of pain will keep me from training.

I will forget the fact that the amount of chakra-induced self-inflicted damage associated with the Chidori was enough to knock me to the ground, knock me unconscious, and send me to the hospital.

I formed the Chidori again, this time with no pain.

Oh, there are so many ideas I have for the Chidori! For one, the whole shape change Chidori thing needs to happen sometime. Sasuke could essentially throw Sith Lightning with a shape changed Chidori.

I also have to change the makeup of the Chidori itself somewhere down the line. A lot of lightning's more dangerous properties were sealed away in the making of the Chidori. The heat of the lightning was scaled down, and the speed at which the lightning could be wielded had to be slowed down, all for something as stupid as the user's safety.

But I didn't need any of that!

Who cares if the Chidori gave me burns on my hand? The pain would just give me more chakra.

Who cares if the the lightning literally tore me apart from the sheer speed at which it was going at? Even if I arrived at my target half dead, I'd have enough chakra to make another Chidori in no time!

That being said though, I need to learn medical jutsu as soon as possible. I can't have my body entirely mutilated during a fight, yeah? The cycle would essentially be this: mutilate yourself for chakra, heal yourself with the chakra you generated with the pain, rinse and repeat.

I grinned at the sparkling mass of chakra in my hands. Chidori, you and I have work to do.


A/N: A few of you said that you actually liked the name of the Fic, so maybe I'll keep it after all.

In other news, I was originally going to have the origin of Seidome's power be the meteor from Hoshigakure. The way that story was going to go down would be that Seidome would have a piece of the meteor stuck in his heart, and that the corrosive chakra of the meteor would eat away at his body whenever he used a jutsu, effectively turning him into a Rock Lee with no gates. He wouldn't have been able to use chakra at all. Then I realised that a character like that wouldn't be able to stand up to the endgame, so yeah…

I actually thought about pretty much all of the options that Seidome comes up with at the hospital. I kept on thinking about different mashups between the meteor, the Jiongu, and whatever else I could think of, but I eventually decided that the Reibi would keep the continuity of the story so far relatively well (there's a bit more explanation coming up in the later chapters), and that it would be viable for endgame. The other options were just really convoluted when I really thought about it.

It was the whole thingy with the meteor that was the nerf that I planned on doing. Originally, some bullcrap with Orochimaru gets involved and he gained immunity to the corrosive meteor chakra.

It's a shame that I felt the need to scrap those ideas. Pika5490, in particular, seemed rather excited for the 'shazzy gold.' So, I'm considering doing a spin-off of this later on using one of the other possibilities that I've cooked up.

As always, review, and give me some feedback!
