"I'm…a good lil….bunny slut…"

Daiki paused in the process of stretching out after pulling his clothing back on and looked over his shoulder at the sound of Mirko mumbling, beholding the sight of her face down in the pillows, ass up. Her womanhood and and anus were stuffed so full of his semen it was trickling out of her like a steady river and, not only running down her thighs but dripping straight down into a great deluge of a puddle that had forever ruined those bed sheets.

'Oh well.' Daiki smirked and shrugged, it was just a random bed he'd pilfered to use on the fly whenever he needed. He could just get a new one. He looked away from the gorgeous chocolate skinned bunny hero and looked at his arms as he stretched them out.

Easily.

Despite the fact he was wearing a hundred tons per limb. It was to be expected he supposed. Shisui Uchiha, was if not a kage level ninja, then approaching that level, and definitely S-class.

He'd combined his body with Shisui's through Overhaul, merging their physical capabilities together and then brought the limit of his new body to its current physical peak.

Numerically his strength had simply jumped from around two hundred and fifty to three hundred and eighty or so, on paper and number that seemed to be around a fifty percent increase.

But no, the numerical indicator of his strength stat, was no linear. Right now, he was actually easily five times physically stronger than he was before, if not a bit more than that.

While that was all well and good, incredible even.

It was important for a simple other matter.

He needed to increase his weights again because one hundred tons per limb was simply too light for him now.

"Maybe a jump to five hundred per limb this time?" Daiki mused.

He was sure he could lift that amount now, but would it be enough to strain him to grind with? That was the question.

"Let's check and try one out." Daiki hummed, bringing his hands together in a ram seal and focusing on his right wrist weight. A flare of chakra caused it to glow blue, and the weight increased five times over.

Almost immediately he felt the strain to hold his arm up multiply, "Hmm…" Daiki continued humming thoughtfully as he lifted his arm up and down, testing the resistance, and while he did need to actively put effort into it, it wasn't as much as he was expecting, "…Half again should do it by my estimates."

So that would be seven hundred and fifty tons.

He brought his hands back into the ram seal, and with a flare of chakra, the weights on each of his limbs increased to seven hundred and fifty tons each, for a total of three thousand tons in total across his body.

"Oh yeah…!" Daiki grinned as he threw a few experimental punches, a few kicks, and then bounced on his feet a bit, "I can definitely feel it now!"

With this much weight on him, he was probably reduced back to a bit below his top speed before he arrived in this world and assimilated Shisui.

"Now then." Daiki turned back to look at the fucked silly Mirko and took in her nude form proudly for a moment, "I suppose I'll need to get you dressed huh?"

It really was too bad she wasn't interested in coming back with him.

"Oh well, I can always come back later to see you," he chuckled, before remembering something, "Oh that reminds me."

He walked over to Mirko, before winding his hand back and delivering a firm spank to her bodacious brown cheeks that sent them rippling erotically.

"Mmm…" Mirko moaned into the pillow submissively.

And when he pulled his hand back, there was a familiar seal engraved on her ass cheek.

He admired his handiwork, like a symbol of ownership. Before her realised something else, "Oh wait, I tore your outfit to shreds." he remembered.

Oh well, he'd just have to put some of his clothes on her and-

Suddenly Daiki's eyes lit up as an idea came to mind. Both for something that he wanted to see, and something that would get a hell of a reaction.

Holding his hand out, he summoned a pair of black t-shirts and a few golden jewelry trinkets he'd yoinked from Everlue's safe before taking his place for himself.

He sat them atop Mirko's body, before activating Overhaul. The trinkets warped into a liquid state, before reassembling into a necklace around her neck and a few bracelets around her arms and thighs.

And then he did the same with the black t shirts, the fabric warping completely in shape, before sliding around Mirko's body and forming into a very specific outfit.

'I wanted to see what Emerald would look like in one, but seeing Mirko in one first is just as good.' Daiki's lips formed into a shit eating grin as he grabbed Mirko and sat her up, the bunny hero swaying dazedly atop the bed, clad in a skimp black harem girl outfit embroiled with gold, and gold jewellry that stood out amongst her dark skin.

Her huge tits were barely held in the thin straps of cloth bra. While the slinky black skirt flounced more akin to a loin cloth that draped slightly over her crotch and barely covered her voluptuous round ass cheeks.

Spoiler

"Now that's a good look." Daiki licked his lips.

Very sexy. So sexy in fact it made him want to mount her all over again despite the fact he'd already spent for hours destroying her.

Which reminded him-

He touched her again and used Overhaul to get rid of the sperm leaking from her holes and covering her body, and clean her up a little bit.

Such a handy quirk.

'Too bad I really need to get a move on.' Daiki sighed, giving Mirko's gorgeous form dressed up like a proper harem girl for him a forlorn look. He'd already spent over five hours in this world now, he probably wouldn't have any time to find Derflinger a good fight before he had to go back to Louise's world.

'Actually, about that,' Isobu who had been silent for the last few hours of bunny breeding spoke up, 'I've found something interesting. How it works I do not know, but it definitely works to our benefit.'

"What do you mean?" Daiki raised an eyebrow, crossing his arms over his chest.

'It's thank to the fragment I left back in our original world in my pond, and the clones you left behind in the last world,' Isobu continued, 'As you know I can see through your clones and talk to them at any time just like you, and I can perceive what my fragments do as well.'

"…Okay?" Daiki raised an eyebrow, he wasn't sure where he was going with this.

'Simply put, they're perceiving time a lot slower than we are right now,' Isobu explained, 'Roughly thirty times slower by my estimate. Since it's the same for your clones as my fragment, I've come to the conclusion that when you enter a new world through the odd way you have been, you are somehow interact with the flow of time in that reality somehow, and it is noticeably sped up. Or perhaps the worlds you've been to after having you break through their space-time continuum, slow down in pace for a while after you leave. I'm not sure how this is happening at all, merely that it is. But, regardless of the how, it does mean that we actually have a lot more time on our hands.'

Huh.

That….that was something alright.

Daiki wasn't even sure how to react to it either. It was pleasant news though. And, opened up a whole lot of avenues.

For one, it meant not even five hours had passed for Mirajane since he left her behind. Not even fifteen minutes had passed in Louise's world.

And in his home world, it was probably only reaching the time he was set to go in his mission to the Hidden Mist Village with Anko.

'…Even if I spend an entire year jumping between dimensions before finding my way back home, I'll still get back in time for the Chunin Exam third round and the invasion.' his shit eating grin returned.

That was…incredible!

Even with the talk he and Isobu had and him agreeing, that didn't mean his desire to return home had disappeared, nor his worry for things that could go wrong. He'd just put it at the back of his head at Isobu's urging.

A tension in his shoulders he didn't even realise was there eased out, and a content relaxed feeling spread through him.

"Looks like fun is fully back on the menu." Daiki laughed happily, pumping his fist into the air.

There was a tension in the air Ochako hadn't ever really felt before. It wasn't just around where she was either.

Ryukyu paced back and forth across the roof in front of her, her body energy radiating agitation and worry despite her best efforts to hide it from her and her other schoolmate who were with her.

The entirety of the city, no, the entirety of Japan was tense. Fear was palpable. Panic was rising in the streets, and the public outcry was almost nauseating.

And, if some overheard conversations were to be believed, it was spreading beyond Japan. It was not every day after all, a boy from another world came to visit and caused the…sheer mayhem this one had.

A boy who had casually murdered top tier villains, easily beaten down incredibly powerful heroes with no effort, and even apparently killed off the league of Villains in the blink of an eye…and was still planning on seeking out the greatest villain of all, just to kill him and take his power.

'Deku-kun…' Ochako grimaced, she couldn't hide the worry herself. From what she learned, he alongside Togata-senpai had been the first to encounter Daiki Yurei, and were soundly defeated without any effort at all, and who both were in the hospital after their encounter.

Just like Fat Gum, Kirishima-kun and Amijiki-senpai. And dozens of other heroes who had arrived at the scene.

…Not to mention, the missing rabbit hero Mirko, who'd went missing atop this very roof she was standing atop right now. She'd been defeated easily and kidnapped on live television, for the entire world to see.

"Calm, calm calm Ochako-chan!" a comforting hand on her shoulder made her look to her side to see Nejire-senpai giving her a bright smile, "It'll be alright, you'll see!" the peppy older blue haired girl told her.

She gave her a shaky smile back, "Hopefully." was all Ochako could reply with.

She wasn't even sure what she was doing here. All the strongest heroes in the country were mobilized around Tartarus, Daiki Yurei's target before he up and disappeared a few hours ago after thoroughly trouncing Mirko on live television and disappearing with her to who knows where.

She should have been sent back with Tsuyu back to U.A instead of being involved in this. But, Ryukyu's role had been to grab Mirko and flee from Daiki Yurei if things went south. Ochako was chosen to stay because she could remove Ryukyu's weight and allow her to fly faster to get away, alongside Nejire-senpai who's job it was to harry him if he chased.

"It will be, I'm sure Mirko is fine! And we'll be fine too!" Nejire just continued to beam, hopping in placing cheerily, "It was only villains that got hurt bad by that kid. From what we saw, he was pretty light on we heroes. And just look at what we saw, what happened to that poor cute little Eri-chan. You know it's no wonder he was steaming mad at villains you know?"
Tell that to Deku-kun who had a broken knee and a broken arm.

…Granted he might have just overused his quirk again and hurt himself. He did that a lot.

'Not to mention, he wasn't even phased after killing those villains.' Ochako thought with a heavy swallow. Then again…after seeing what those villains did to Eri-

Ochako had almost thrown up when she saw the display personally on the live television in town.

If that was the first thing he came across upon coming to their world…she could see why he would be so furious, especially someone like Daiki Yurei who was a trained child soldier himself by his own words.

"I bet he's not that bad a boy," Nejire shrugged, "Bad guys don't get angry over little girls being hurt you know?"

Well, she supposed.

"Yeah…maybe he isn't that bad?" she offered back hopefully.

"Nah, I'm pretty bad," a voice suddenly said from behind them, "I'm a bad bad boy. Are you guys here to punish me?"

Ochako's eyes widened and she whirled around in shock at the sudden voice, to find Daiki Yurei himself standing behind her, carrying a scantily clad Mirko over his shoulder like a sack of potatoes.

And he was grinning right at her!

…Or maybe it was Nejire he was grinning at?

"Now this is a pleasant surprise, gotta admit."

The way the boy so casually eyed them outright appreciatively, while carrying Mirko over his shoulder like a shopping bag full of mochi, had every instinct in Ochako's body working into overdrive.

How did he just appear without them noticing a thing? Without a sound? Anything? They had all been facing different directions and still none of them had noticed!

"I didn't think anybody would still be around here when I came back," Daiki mused, a large confident, pleased grin atop his lips, "So are you girls here to be my escort to Tartarus?"

"I'll happy lead you into one of their cells if you want," Ryukyu spoke up, taking point to address the boy, yet Ochako couldn't find it in her to relax at all, or even feel relieved at all, "What did you do to Mirko? Let her go!" she demanded, making her way out to stand in front of her and Nejire.

"I think the real question is, what didn't I do to her?" the boy just grinned wider, "Besides, not like it wasn't anything she asked for anyway. She was the one that decided since she couldn't beat me in a fight, she'd just get fucked by me instead."
Ochako's eyes widened, and her cheeks blazed with heat as she heard what he said, '…Then the whole time they were gone, they were having sex?!' she sputtered inwardly.

And he was so casual about it!?

Wasn't this guy even younger than her?

Ryukyu grimaced, "…That doesn't account for her state at all, look at her!" she waved her arm at the comatose dark skinned rabbit hero across the boys shoulder, "I question the kind of thing men and women get up to where you're from if beating a woman unconscious during the fact is-"

"The hell are you talking about?" the boy cut Ryukyu off with a snort, "Unless you count a beating as me spanking that huge round ass of hers while we went at it? She just couldn't handle me even after I gave her a power boost."

Spanking? Couldn't keep up?

In any other situation, Ochako felt she'd probably have steam boiling from her ears with the kind of stuff being said around her right now.

This guy, the way he acted and the way he spoke-

He was like the personification of everything Mineta wished he was, for sure.

Still, one thing stood out from what he said to her;

"A power boost?" Nejire cut in, even as she levied her arms at the boy ready to unleash her quirk, Surge at a moments notice, "You can do that? Just power people up? Is it through sex? Is that why you guys took so long? You were away for a whole at least four hours. Were you having sex that entire time? And what's with that outfit she's wearing?"

Unlike Ochako, Nejire didn't seem phased at all at the boys mention of having sex with Mirko. Instead, she rapid fired question after question his way while bouncing up and down on the balls of her feet.

The boy, Daiki blinked his head cocking to the side at Nejire and looked almost confused.

Albeit for only a split moment before his grin was back.

"In order," he started, holding a finger up and ticking more off with each word he said, "Yes. Yes I can. No, though I could probably do it while fucking. We didn't take that long, four hours is pretty short, usually I go for a minimal of ten hours when having sex. For the most yeah, we were fucking that entire time. And it's a harem girl outfit, I made it with one of my abilities since we tore her costume apart, looks good right?" as he finished, the boy lowered Mirko from his shoulder and lay her down in front of him.

Good wasn't the word Ochako would use. Obscene more like. It was little more than a few strips of thin wavy cloth and dazzling gold jewelry accessories-

Wait.

"Is that real gold?" Ochako couldn't help but gape as she looked over the out cold and obscenely dressed rabbit hero.
No way, it couldn't be and-

"Yup, good eye Ochako-chan~" he winked at her, "I figured if I was gonna dress her up like a concubine, I should at least make it look legit."

Unbelievable, she wasn't exactly an authority on gold or anything, but considering the size and weight of those they would have to be worth tens of millions of yen, each.

Wait.

What did he just say?

"…You know my name…?" Ochako's eyes widened.

How?

"That I do, Uraraka Ochako-chan," the boy winked at her, "I know all your names actually. Like Tatsuma Ryuko and of course the gorgeous Hado Nejire."

Nejire perked up, a big smile on her face despite the situation, but Ryukyu cut in before she could reply.

"How?" Ryukyu demanded, "By your own word, you came to this world perhaps an hour at most before running into Mirko, and while she knows who I am, and may perhaps know about Nejire working at my agency, she knows nothing about Uravity. She only started interning with me a few weeks back and Mirko cares nothing for that kind of thing."

"Nothing special, I just read that Deku idiots mind," Daiki rolled his eyes, "He was an absolute buffoon, but a useful one in a few ways. One of those ways being the fact that he has an almost encyclopedic knowledge on heroes, their personal lives and their quirks."

He shook his head and frowned, "Honestly, probably not my best idea to be honest, being in that guys head was bizarre, and the sheer amount of trivia I know about All Might now is almost sickening," the boy said, before looking directly at Ochako herself, "FYI, you should tell your teachers to have that guy see a psychiatrist, he's a walking martyr complex and he's gonna end up dead in a random ditch somewhere at the rate he's going."

Ochako's mouth opened and closed, trying and failing to find words. Just how was she supposed to respond to that?
Even so.

"Just because you plucked information from his mind, doesn't mean you know him!" Ochako shot back, despite the situation.

Sure Deku had his problems here and there, but they were by far a minor thing. He was kind, and hard working and put more than anyone else she knew into pursuing the path of a hero.

And she wasn't going to let some guy insult her friend like that, after he'd put him in the hospital in the first place!

"Trust me, I wish I didn't know him, but don't say I didn't warn you when he ends up dead before ever actually becoming a hero," Daiki shrugged casually at her rebuttal, "Not that he's worthy of the title anyway. Granted, few of you actually do deserve it. You're all more like government employed mercenaries."

Ryukyu scoffed and walked forward, taking Ochako aback at the sudden action as she re-entered the conversation, "Yes, we'll be sure to take advice on being heroes from the child soldier and-"

Her tone was sarcastic and almost casual, but it belied her sudden instant transformation as her body swelled up to titanic properties and morphed into that of a western dragons.

She took advantage of the boys attention being on Ochako, to approach with words and leap into action and take him off guard.

A massive dragon claw slammed down with car crushing force atop the boy, and the entire building shook as if an earthquake went through it.

And for a moment, Ochako felt hope swell up within he chest, surely that….

Her mouth dropped open as she bore witness to something absolutely unbelievable.

Ryukyu's dragon claw, swung at full strength that could crush a small building easily was stopped.

By a single finger.

"Nice try, but no." Daiki laughed, a single finger outstretched from his hand and pushing against Ryukyu's massive dragon palm, stopping her blow entirely in its tracks.

…Just how?

How could he be so strong?

Seeing videos of him in action and his boasts were one thing. Seeing it in person was a completely different matter.

And then suddenly he was gone, the finger holding back Ryukyu's blow alongside him, and without it there, Ryukyu's momentum carried on and she stumbled-

Before the building shook all of a sudden and Ryukyu was pinned to the roof face first, and with Daiki's sandle clad foot atop her neck, his hands casually resting in his pocket.

….It was so fast Ochako hadn't even seen him move!

"30 Percent!" Nejire leaped into action while Ochako was stunned, not hesitating despite the sheer absurdity of what was happening. She thrust her palms out, pointing up at an angle, glinting golden energy swirling around her body and surge out in spiralling waves of energy towards Daiki.

Daiki turned his head and exhaled.

A cloud of black smoke emerged from his lips and washed over the waves of spiralling gold energy.

And they completely disappeared!

Some kind of quirk erasure!?

"Just how many powers do you have?!" Ochako couldn't help but cry out in frustration, even as she kicked off the ground and rushed towards him.

She had absolutely nothing to deal with this guy, no plan came to mind, and she didn't come close to him physically.

But even if she could just distract him enough for Ryukyu to get out from under him then maybe something would come of it!

'If I can just make him float!"

She lunged for his nearest arm while he was looking at Nejire-

But both her wrists were snatched up as his nearest hand flashed out of his pocket, without him even looking at her and Ochako found herself hoisted up into the air, leaving her dangling.

"Damnit!" she cursed, snapping out with a high kick towards the back of his neck.

Which landed true.

And didn't even make him budge.

"Not a bad try, but you guys just lack the sheer fire power or strength needed to hurt me at all," Daiki laughed lightly, "An interesting combo of powers too. Brute force with the dragon transformation, sheer power with Surge and Zero Gravity to leave a target vulnerable. With all three of you, you could have probably given All Might a run for his money." he praised them.

Unbidden, the words he said before during that impromptu came to Ochako's mind, where he bragged arrogantly about how not even All Might at his best was a match for him.

….Ochako liked to think she was no slouch, and she trained hard. But even with Nejire-senpai and one of the top ten heroes, they couldn't even make him budge an inch.

Ochako was beginning to believe, that despite the sheer arrogance of his words. The boy was being completely truthful.
And it was as absurd as it was horrifying.

Because if he was truthful about his strength, then there was a good chance he was entirely truthful about what his world was like.

And that was complete nightmare fuel.

"Let go of Uravity no-" Ryukyu snarled from beneath the boys leg and tried to push up against his foot pinning her neck to the ground, but he didn't even budge.

"I'm gonna be honest Ryukyu, you don't really interest me," Daiki rolled his eyes, and pulled his other hand from his pocket and touched it to Ryukyu's head. And she went limp, eyes rolling up into the back of her head as she fell unconscious, just from a simple touch, "Dragon huh? Wonder how it would interact with my dragon force?" he mused aloud, before shrugging and turning to look at Ochako herself who struggled with all her might in his grasp, to no avail as he dangled her in the air.

"Now you on the other Ochako-chan, you're perhaps the most interesting person this world has to offer," he grinned at her, "After all. I know a woman who looks exactly like you back home. Well, she's a little bit older and in her twenties, but you look more or less exactly the same. And the thing is, her name is Uraraka Ochako as well."

"…What?" Ochako once more gaped at the boy, dangling from his grasp all the while Nejire looked on, unsure how to act, Ryukyu was pinned unconscious below the boys foot….and Mirko lay off to the side, still completely unconscious and dressed in an obscene harem girl outfit.

Alright here we be back again breaking into the big two the zero, chapter twenty yay. I meant to upload some stuff back on the seventh. But there's a really good reason why I didn't, trust me, you'll understand.

I couldn't be bothered.

And was gonna upload something different, but then realised this was sitting and ninety nine thousand words, so another update from it would break a hundred thousand on here, so like it or lump it son! Or daughter!

General minion!

Well anyway, Daiki found out some things from Isobu and ran into the main heroine, the dragon girl and contender for best girl. Honestly, best girl in MHA is probably between Ochako and Nejire. Admittedly Ochako took a real hit with that buffoonery around Toga. God MHA is just a complete dumpster fire. Just look at the state of Armless-Ku Cuckdoriya. And now we've got fucking Eri having to fucking mutilate herself just to help out this utter buffoon. He could have ended this way before if he actually had the balls to kill Shigaraki but no 'Oh no lil boy I see you crying in Shigaraki!'

Fuck off Deku.

Deku has truly cemented himself as the absolute bottom of the barrel of shonen main characters and heroes in general.

Well anyway, I bet most of you forgot about the Ochako from the main Systematic Shinobi huh?

Daiki be like: Time to gaslight for shits and giggles!

Welp, that's all for now I guess. As always if you wanna read ahead for advanced chapters of this, the main Systematic Shinobi, Stacking The Deck, Jordinio Version, Beyond Critical, A Scottish Dragon In This Wonderful World and others you can check out mah Pa-atreon.

Anyway, again, shameless Pa-atreon plug. I've got one, go by the same username on there, easy to find and all that jazz. Support me if you want, it'd be swell, but don't feel pressured lads and ladies, I'll be uploading my stuff outside it regardless and not keeping it all behind a paywall or anything like that.
