Systematic Shinobi: Multiverse Mayhem - Chapter 16.1 (Patreon)

It wasn't just Shisui's body he combined with his own. And it wasn't even simply a combination either.

He'd made Shisui's body his own when melding them both together. His full bloodline, became Daiki's bloodline.

For all intents and purposes, Daiki was an Uchiha by bloodline. An Uchiha with an all new, natural version of the Sharingan. That would be passed down through his blood to his children.

But again, it wasn't even just that.

The heart of Atlas Flame turned into a Lacrima, moulded with his own, fusing. His very heart was a combination of Daiki Yurei's, Shisui Uchiha's and Atlas Flames.

His ethernano containers was a natural part of his body, and would be passed down to through his bloodline.

And it didn't end there either.

Isobu's chakra that was running through his network, became naturally a part of his own. The Coral Style would be passed down through his bloodline as well.

As would the quirk factors he'd taken for himself.

Each and every single part of all of that, was now a natural working part of his genome.

And that, was why Daiki laughed.

Because he was now, everything Orochimaru could ever have wished to be. He had accomplished Orochimaru's life long dream.

All by random happenstance and accident.

He laughed and he laughed, basking in the feeling running through him in this moment. It was not just strength.

It was victory.

And superiority over someone he detested.

"That's right Orochimaru," Daiki boasted, even though he was in a completely different dimension, eyes to the sky, peering straight through the tunnel ceiling up through it into the blue sky above, "You can search heaven and earth you loser, but you'll never accomplish your dream. I alone am the honoured one."

"Sounding kind of maniacal there partner," Derflinger spoke up, "Can we go now though? Like I know you just accomplished some big goal of yours and all, but I'm kind of bored."

'Yes are you done?' Isobu piped up, 'Because…we kind of have another problem.'

Daiki stopped laughing and blinked.

'Is it really a problem though? I think he might like it,' Atlas Flame mused, 'It adds a little bit of decour to the place, and now that the place has pretty much doubled in size, I don't see the issue.'

'…I think it's the two other things that's the problem.' Nana murmured.

…What other two things?

'ME KILL YOU FOR BOSS OVERHAUL GIANT TURTLE THING!' a voice he had no knowledge of suddenly roared.

And then he heard Isobu snort, and a yelp of pain from the same voice that roared.

'What the hell was that?!' Daiki was completely taken aback.

'Yes, apparently Nana and those other souls within Izuku Midoriya's quirk aren't unique,' Isobu drily replied, 'Apparently shades of souls are in all quirks, and with the high abundance of spiritual energy within you due to both your and my chakra, you've given those shards of souls you took when you took those two quirks, form.'

Daiki blinked slowly, processing those words.

"Man partner, it's getting loud in there." Derflinger laughed.

It really was.

Daiki closed his eyes, and with a thought he left the physical realm behind and entered the realm of his mind.

He opened his eyes and they bulged at what he saw. His mind scape, was...while not massively different.

Quite a bit different.

The usual place was still there, the overall area and the depths of his chakra that covered it. But now the deep inky darkness overreaching from above, was filled with dim twinkling lights like stars within the vast expanse of space.

…And there was a big rock floating up there too. Carved into the shape of a room, almost like what he saw within Deku's mind, soul or whatever. But, vastly bigger. It was more or less empty, except for a trio of high backed green chairs the same shade as his chakra.

And then there were…those.

A familiar behemoth of a man in a beak shaped plague doctor mask that covered the entirety of his head, pinned casually beneath Isobu's massive hand and flailing about like a wild animal trying to get free beneath it.

…And another smaller, much more normal looking slim built man dressed in a green jacket, and a plague doctor mask the covered only half his face.

Rikiya…and Overhaul.

Overhaul swallowed heavily as they met eyes, the man just sitting almost listlessly on top of his chakra, "I-it's you…" he leaned back, fear and horror shining in his eyes, "…You…you killed me a-"

He never got to speak as suddenly Daiki's foot was on his face and burying his head into the chakra floor below, "Well hello there Chisaki," Daiki grinned, malevolently, "Welcome, to hell." he greeted, rubbing his foot all over the mans face.

"I don't know Daiki, I've been to hell once or twice," Isobu mused, amusement dancing in his eye, completely ignoring Rikiya beneath his hand, "You're much scarier than the demons down there."

"I've met some gods that would run in the other direction from you." Atlas Flame snorted, adding his own two cents.

"…Please tell me you're joking," Nana pleaded with them, she looked like she wished she could be anywhere but here. But she soldiered on and shook her head, turning to Daiki himself, "You should be careful. Their souls are manifestations of the quirks. If you kill them in here you'll lose the quirks as well. And you might damage the quirks themselves if you injure them too much."

….Motherfucker.

Daiki turned to her, though he didn't stop grinding his foot on Chisaki's face, "I'm almost surprised you aren't trying to stop me," he raised an eyebrow at her, "Aren't you some moral hero? If it weren't for what you just told me, I'd happily torture this fool."

Nana grimaced, "You really do look down on us heroes huh?" she sighed almost sadly, "I've already seen enough of you and been filled in enough by Isobu and Atlas Flame to know I won't be able to stop you no matter what."

…Huh. He didn't expect that.

Well whatever.

He took his foot off of Chisaki's face and watched the man grasp at his face, gasping now that he could breathe.

For all of a moment before Daiki wrapped his hand around the mans throat and lifted him into the air, "So I can't hurt you physically without screwing myself over?" he moved, ignoring as the man tried to choke and splutter something out, his eyes bulging. Daiki gave him a smile that was all teeth, "I don't need to torture you physically though, don't think for a second you'll get to have a nice peaceful after life after what you did to Eri." he said, the tomoe in his eyes swirling and dance with the desire to inflict pain.

With the facet of the Shinkugan he projected into the mans mind. With the facet of the Sharingan, he warped the inside of the mans mind, hypnotising him with ease.

And suddenly he was another completely different place, in a warped red and black world. And held afloat above him on a black wooden cross was Overhaul.

"Welcome to an eternity of pain and suffering." Daiki greeted him, a sword of pure darkness appearing in his grasp.

"W-wait I-i p-please! I-i'm so sorry foe what I-" Chisaki tried to plead, but was uninterrupted by the sword being jabbed through his throat. His eyes bulged almost out of his sockets as he was stabbed through the throat, gurgles of weeping pain splashing from his throat.

"Have fun." Daiki bid him goodbye, as dozens upon dozens of monstrous shadowy figures appeared from the darkness, forming all around Chisaki, all approaching him, violence and suffering radiating from them.

And then he left Chisaki's mind and returned to his own, holding the now comatose man left in genjutsu coma of pure torture.

"Enjoy your afterlife." Daiki told the comatose man, before thrusting him down into the depths of chakra below them and letting him go, allowing the comatose spirit to float down to the bottom.

Where he would be tortured for all eternity within his own mind. Well, at least as long as Daiki was alive.

"…What did you do to him?" Nana asked, grimacing again.

"Just a little illusion," Daiki smirked, "I trapped him in an illusion where he'll be constantly tortured within his own mind, nothing major to be honest. Any kid back home was exposed to stuff like this pretty early on to get us used to it." he added.

Nana gaped at him in horror, "…That's….that's horrible." was all she could say.

"But well deserved for this guy," Daiki shrugged, then looked to Isobu, "You want to hand your new toy over? I'll genjutsu him unconscious and toss him down there with his boss."

Isobu shrugged and tossed the behemoth of a man over towards, "HAHA RIKIYA FREE! ME SAVE MASTER OVERHAUL!" the man laughed gleefully as he flew towards Daiki, fists outstretched like Superman.

Daiki looked through his mask, into his eyes.

And he fell splat at Daiki's side a second later, completely unconscious. Before sinking below into the depths of his chakra and disappearing from sight.

"I'll need to keep in mind peoples souls come with their quirks I guess." Daiki mused, before shrugging and leaving his mind behind once again.

So many distractions!

Honestly, it was like the world was bending over backwards to protect that buffoon All For One from his fate.

And Daiki's fist tearing out his throat.

___________________

Sir Nighteye held a tissue tightly to his nose, pinching the bridge of it at the same time as he approached the remains of the Shie Hassaikai's base of operations.

It was horrible. The stench of death was obscene. Not only from the massive amount of blood and feces that stained the streets all around from Rikiya's remains-

But the sheer amount of corpses that littered the base remains. The vast majority of them were scorched black. Most likely from that massive lightning dragon that struck the area.

He inched around, taking in the sheer death around him, and paused as he came across two specific bodies that stood out more than the rest.

A girl, with a man in full costume curled over her protectively as if to shield her. Though of course he failed.

'Toga Himiko and Twice!' Nighteye's eyes widened in shock. Two members of the League of Villains?

His intel was correct then? The League of Villains had been reaching out to team up with the yakuza group?

And through this attack they had lost at least two of their members. Such a horrible waste of life…but regrettably to their benefit, especially with Toga dead. She was a mass murderer and known serial killer after all.

Whistling and steps suddenly echoed loudly and Nighteye whipped around just in time to see a young broadly built boy casually stroll up out of a hole in the ground.

Very young going by the face, no older than Midoriya. Tan skin as if he spent a large amount of time in the sun. Short spiky black hair. Tall of height for his age, approaching six feet tall, and with a very broad build and incredibly defined musculature that was plain to see with the way the boy was dressed. In just a tank top, shorts and a pair of sandals of all thing.

He looked like a boy on his way to have fun at the beach, not someone who had just casually massacred a yakuza group.

Sir Nighteye tensed as the boy looked at him, his eyes immediately going to the gleaming silver blade hilts hanging over his back, just as Mirio reported-

And then the boy took his eyes off of him and…walked right passed him, completely uncaringly?

The boy began whistling again, completely uncaring of his presence, hands in his shorts pockets even as he walked away!

Nighteye tried to open his mouth. Tried to call after him, stop him-

But his voice was caught in his throat.

Something was pressing down on him, rooting him to the spot, forcing him there and keeping him from acting.

It was not fear.

No, nothing like that was effecting him.

It was something he recognised though. It was sheer presence. Sir Nighteye was well aware of the feeling. He had been in such presence before, every day even for a time.

When he was the sidekick of All Might.

But yet…even that presence, the presence of All Might. The greatest hero to ever exist. The symbol of peace and justice-

Was like a candle compared to a roaring bonfire in comparison to the presence just radiating from this young boy!

And so he could do nothing but stare as the boy walked away.
