Systematic Shinobi: Multiverse Mayhem - Chapter 1.1 (Patreon)

"…You are one ugly ass monkey."

Tilting his head to the side, Daiki casually avoided a rather massive, yet slow purple skinned fist aimed at his face, staring up bemused at his attacker. It was a massive monkey, or gorilla creature covered in deep green fur, except on the hands, feet and face that showed off light purple skin.

"Dumb hooman stop move!" it hollered at him in agitation, its ugly face, topped with a literal pencil thin topped head contorting angrily and lashing out with a thrust kick from one of its disproportionately thin and tiny legs.

Only to goggle at him in shock as he caught the kick in the flat of his palm easily.

"You're not a summon at all for sure, I can't see or feel any chakra in you," Daiki mused, "The fact you're alive at all without chakra is pretty much a given as far as explanations go for where I am I suppose."

Or at least where he wasn't.

Old man Sarutobi was seriously going to kill him when he got back home. He was due to be heading out for his mission to wave in literally like three hours. After he'd gotten his newly thought of Yang Conversion Seal down and added it to his Heavenly Star Seal, he'd been struck by inspiration.

And decided to try his hand at reverse engineering the Flying Thunder God technique. And he had succeeded.
For sure.

…And then just when he was testing the seal out, after jumping the gun and not waiting for the ink to dry…a fly had landed on the seal.

And he ended up here after swerving through a massive tunnel made up of kaleidoscopic lights.

In the middle of a forest. With a giant ugly monkey attacking him for whatever reason. A giant ugly monkey that was vaguely familiar, and could talk.

"Me kill you hoo-"

With a roaring snarl, it shook of its surprise at him casually stopping its kick and smashed both of its huge fur covered arms down towards him.

Only it never even got halfway through the motion.

In a blur of motion, Daiki transitioned into a one handed hand stan atopi the giant ugly monkeys leg that he had stopped with his palm.

And launched a heel kick into its chin and launched it flying, its head twisting at one hundred and eighty degrees.

Flipping, Daiki landed on his feet easily and stared as he massive monkeys body flew over a hundred feet through the air, before ploughing into and through a tree, forcing it to explode into thousands of wood chips and fall limp, dead.

"…Wow, it's so fragile despite its size." he goggled, actually taken aback, he'd held back quite a bit with that strike….and accidentally killed it regardless.

Oops?

'Is that not a vulcan?' Isobu piped up after he stared at the giant monkey corpse for a few moments.
"Vulcan?" Daiki blinked, before his eyes widened in realisation.

'Yes, from Fairy Tail.' Isobu supplied helpfully.

…Oh shit.

Well he definitely wasn't in Konoha anymore, that was for sure. Fuck. And another entirely different universe…again!?

'This is what happens when you play with high level space time techniques like an autistic child.' Isobu snorted, amusement colouring his voice.

Why did he…

"Why do you not sound bothered by this at all?" Daiki stopped still, a weird look appearing on his face, "We're literally in a completely different universe right now and I have no idea how to get back."

'Why wouldn't I be?' Isobu snorted, 'Think, you just said it. We're in a completely different universe, cut off from our world and everyone in it.'

"Yeah….we're so far from home it's not even funny Isobro, and the longer we're away the more danger our world is i-"

'Wrong actually,' Isobu chortled lightly, 'Remember, you're big deal was stopping the Juubi and by proxy Kaguya from being reborn. Without me, it will be impossible for Madara's plans to come to fruition. You've literally by accident saved our entire world due to your messed up seal, that's hilarious. The grind always provides you say? It sure did!'

But…but…but-

That, but that just wasn-t

Daiki's thoughts trailed off as he stared at the corpse of the giant green monkey monster blankly.

"I…was preparing for a giant cataclysmic battle, jutsu that could tear apart countries, meteors that could desolate the planet…a guy that could literally make time his bitch…." he mumbled to himself, "And yet, I win, years in advance before the fights I was preparing for, because I accidentally removed us both from the equation?"

'Yep,' Isobu's chortle turned into full blown laughter, 'The grind truly works in mysterious ways, huh Daiki?'

Yes, yes it did.

He should be happy, he really should. With this, his world was safe and he would never have to worry about facing off against insurmountable godlike monsters like Madara Uchiha or Kaguya Otsotsuki….

Yet why did he feel so strangely disappointed by that fact?

'Because you're an absolute maniac,' Isobu deadpanned, 'And despite that massive terror you've felt for Madara since the very beginning, deep down persisting even amongst that fear was the excitement to reach his level and fight him in some edgy climactic showdown. Honestly, I didn't want to say anything, but it was kind of pitifully cliche.'

Ah…

Daiki honestly didn't know how to respond to that. Like he wouldn't lie, he loved fighting. He'd actually been super disappointed at the fact Ino had been his opponent in the prelims.

Fighting against old man Sarutobi for an entire week while training with him? Despite how exhausting it was, despite how many times he got beaten bloody and had his bones broken, he'd relished it. He'd felt even more alive in those moments, than when he was pounding the ever loving shit out of Anko and making her squeal his name to the high heavens.

…So he couldn't deny Isobu's words, even if he didn't quite feel that he did in the same way. There was simply too much riding on defeating Madara if he ever popped back up out of the grave, to even conceive the notion that he would be excited about it.

'Yes well feeling like you had the literal weight of the world atop your shoulders will do that to you. On top of the fact that freak of nature only lost because of betrayal, and otherwise would have been unstoppable,' Isobu snorted, 'I like to think I know you even better than you know yourself at times, you're just not consciously aware of it right now, but subconsciously? I could literally feel the weight falling from your shoulders and the relief spread through you completely the second you realised what my words meant.'

Maybe…but he could feel a small pit of guilt in his stomach. Even if them having left the world rendered Obito and Madara's plans moot, it didn't change the fact that suddenly he'd left the village that he'd promised the old man to protect, and the friends.

His cute little apprentice would be lost without his guidance! she was already stronger than her alternate timeline self. What if she got promoted at a younger age and thrust into a situation against evil bastards like those filthy rock humpers that jumped him? Without him around to save her!?

Daiki might not have relished the idea of becoming Hokage, but when he made a promise, he intended to see it through!

'Well, you can always go back I suppose, it puts the entire world at risk, but you're not Naruto. You don't actually care about the world itself all that much, there's a reason Danzo actually likes you,' Isobu snorted, 'Of course, I've no idea how you would even go back, but it's still something you can aim for.'

Well…he wasn't wrong there.

Daiki looked down at his right. hand, where a sheet of sealing paper was clasped in his palm. It was the flubbed flying thunder god seal. Looking it over, he could recreate it easily enough, it was a simple change that had been made through something as minute as a flies body after all smudging the ink.

…And it could be possible for him to create beacons using it to return to the seal itself if he left it behind somewhere. The problem was, he hadn't left a variation of this seal behind in their own world.

So he'd be forced to basically use the seal itself over and over again and hope he got lucky and landed back home.

…And considering he was in Earthland, the world of Fairy Tail right now, that could be take a while. There was no telling where he'd end up next.

'Well, beyond that, this does present an opportunity,' Isobu mused, 'After all, you're currently in a world where it would be rather easy for you to gain the power to become all but immune to certain elements.'

Oh right, that was a thing wasn't it? Dragon Slayers and it was possible to become one through a dragon lacrima, like the ones Laxus and that Cobra dude had.

…Being immune to poison would be incredibly helpful. Actually, being immune to lightning would be amazing, he'd be able to use his Lightning Chakra Mode without any repercussions!

'Yes, but you're jumping the gun a bit and forgetting something,' Isobu spoke up, 'Pull up your status screen, I think it should clue you in to what I'm thinking.'

Daiki blinked, before shrugging and doing just that, and his eyes widened at what he say being reflected back at him.

"….Eh?" Daiki trailed off, just staring for a moment at the status reflecting back at him. Over the course of the night, he'd risen to the expert point with his Fuinjutsu skill, which was likely one step off of master. Usually he would have been incredibly excited about that.

But something else took up his attention.

Ethernano Capacity(E?).

A new stat? Had inscribed itself upon his status screen. The name of the energy source used for magic in the world of Fairy Tail at that. But, any numbers or anything for it like his chakra capacity was suspiciously absent. Though that E in the brackets followed by a question mark seemed suspiciously like a ranking system, just like how his chakra capacity was at the level of a lower tier kage level shinobi.

'Ethernano is the natural energy of this world remember? Your heavenly star seal passively draws on natural energy and filters it into your body, among other things,' Isobu helpfully explained, 'While it is melding with your chakra, all it's doing is amplifying the power of your chakra like normally. You don't possess an ethernano container like the residents of this world to properly utilize the energy source in the form of magic….yet.'

Oh that made sense.

But, how was he supposed to actually get an ethernano container? A lacrima was one thing, but he didn't remember anything specific in the series itself showing exactly what an ethernano container was or where it was located? For all he knew it could have been a metaphysical thing and part of the soul.

'It did actually, or at the very least I'm fairly certain I know where the ethernano container is in a mages body,' Isobu hummed, 'It's a good thing for you I'm simply much smarter and more observant than you."

"Yeah, and how do you figure that?" Daiki retorted with a smirk, crossing his arms.

'Because you were too busy leering at the likes of Erza Scarlet on the screen to truly pay attention and catch the little details,' Isobu snorted, 'But we can easily test my hypothesis with that stupid monkey you just killed, they have magic of their own no? Take Over is it not?'

….Yes, yes they did.

Daiki turned his gaze towards the giant dead monkey and gazed at it, "So where would it be then oh all knowing turtle boy?" he asked.

'You should be able to tell yourself, look through its outer body with your Shinkugan, get a look at its eyes heart and lungs,' Isobu instructed, 'If I'm correct, the heart should be the first ethernano container and the lungs the secondary one that allows for the usage of second origin.'

Shrugging, Daiki did just that and flowed chakra into his eyes, his vision rippling slightly as he looked straight inside the corpse of the beast, and blinked.

It was faint, but there was a shimmering green aura of energy within the heart of the beast. And it looked to be flow towards the lungs? But failed? As if there was some form of invisible wall blocking it.

…Huh.

'As expected, I notice things while you're too busy drooling over tits,' Isobu laughed in amusement, 'Where would you be without me brat?'

…Probably not in Fairy Tail at least.

'That was rhetorical you buffoon,' Isobu huffed, 'Now just be a good boy and go rip out the dead monkeys heart and lungs.'

Heh, he totally won that one.

'You keep telling yourself that, one day it might even come true…doubtful though.' he could practically see Isobu rolling his eyes

Daiki just laughed and did as he was asked, strolling over to the giant monkey corpse and lifting his hand up, two fingers pointing out. wind swirled into existence around his finger and with a flick of them, he carved the beasts chest open with a blade of wind, exposing its chest cavity.

It was a simple, if messy matter to reach inside and cut out its rather large heart and lungs, "I obviously can't transplant these…." he mused to himself eyeing the bloody organs in his hands, before sealing them within his Dimension Force Seal upon his palm, "Guess I gotta make a new seal."

'Not really,' Isobu input, 'Your bloodline usurping seal has already laid a big enough ground work for it. You don't need to integrate it into your blood like the bloodlines you plan, you simply just need its effects as a container for ethernano by overlaying them with your heart and lungs.'

Hmm…true. That would work well enough yes, it would mean he couldn't pass an ethernano container down through his blood until he completed the Bloodline Usurpation Seal but, he had already got roughly a quarter of that done and dealt with, by his estimates, now that he was using three hundred clones instead of two hundred clones to train daily, then he could probably finish it up within a few weeks.

…It was highly unlikely he was going to impregnate anyone within that time frame.

'You never know with you,' Isobu snorted, 'Beyond that, use those silly eyes of yours and locate another one of these ugly vulcans will you?'

"Why?" Daiki questioned, confused. The set he had already would be well enough for him to make a set of ethernano containers of his own.

'Because, I have an idea for the future if we ever return to our world,' Isobu replied, 'As such, I want you to go kill another of these stupid monkeys so I can devour its corpse. Unlike you, I won't need to worry about organ rejection or something like that, I'll just add its body parts to my own. And then once I get a feel for the energy I should be able to make it a natural part of my body.'

Huh.

"Wait, what kind of idea?" Daiki asked, eyebrow raising in interest.

'How does Bijuu Slaying Magic sound to you?' Isobu replied simply.

Daiki's eyes bulged.

________________

Since we're back on Systematic Shinobi, I suppose I may as well upload this as well. It begins specifically at the very end of chapter 52.2 more or less where Daiki got a little bit overzealous after finishing early. Also a bit of an AU with him getting the Flying Thunder God schematics from old man third.

It's a multicross that will go through a bunch of other series, just a fun little romp and as you can see starts with Daiki landing in Fairy Tail. From there, there's a ton of different places he could end up like Black clover, Danmachi, Avatar, Jujutsu Kaisen, Bleach, Seven Deadly Sins, Boruto the Burito. I even made a bit of a crappy cover art for it from fan art, or tried and failed the the resizing and fucking up the pixels and will need to make a better version later. But, here have a look anyway.

If you want the artists of them, well three of them are Ai art I think and don't matter, one is from the Black Clover anime and the Neo pic was down by K1mmy who I think also has a patreon if you wanna check that out.
