Nezu's Office, U.A. Staff Meeting

The room was silent, save for the faint hum of the AC and the occasional rustle of papers as each teacher looked down at the check lying on the table like it was some sort of alien artifact. Written in neat, precise handwriting, the slip of paper stated one thing:

Investment: 80,000,000 USD.

There was a collective, stunned reaction that left every U.A. staff member gaping. Present Mic's wide eyes almost popped out of his head as he leaned forward, squinting at the digits like they were going to change. He was the first to break the silence, his voice loud and incredulous. "Eight—eighty million?! Who the heck is this kid, and why does he have that much cash?!"

Ectoplasm nodded, still staring at the check. "I find it hard to believe anyone can have that kind of money without... suspicious sources. Who has that kind of disposable income without breaking a few laws?"

Nezu's whiskers twitched in mild amusement. "I thought the same, to be honest. But our investigation into Kazuya Akiyama's background turned up nothing incriminating. In fact, his record is surprisingly clean." He shuffled through the stack of files in front of him and pulled out a few sheets. "Apparently, the Akiyama family has been investing in cryptocurrency and various companies for a long time. According to all the available information, Kazuya's name is on the list of the richest multibillionaires in the world."

The room fell into a deeper silence, everyone's eyes widening further.

Midnight's mouth dropped open. "A multibillionaire?" Her voice was faint, still reeling from the revelation. All this time, she'd been interacting with Kazuya like he was just some random kid, never once suspecting that he was swimming in a pool of wealth most people couldn't even imagine. And worse, he never even hinted at it. No grand gestures, no arrogance. It was completely baffling.

"Yep," Nezu continued, his tone almost lighthearted, "the Akiyama name is apparently one of the low-key powerhouses in the business world."

Snipe, who had been quietly absorbing the information, leaned forward with a frown. "Hold up, you're tellin' me you believe that nonsense, Nezu? All that 'investing in crypto' and stock market stuff? It sounds like a load of crap."

Nezu smiled, a soft but mysterious expression crossing his face. "It does sound ridiculous, doesn't it?" He nodded thoughtfully. "I agree—it's too convenient. The records are too perfect, too clean. There's no way to amass that level of wealth without some skeletons in the closet. But the fact that we can't find any... well, that in itself speaks volumes about how careful Kazuya has been in covering his tracks."

Aizawa crossed his arms, his gaze hardening. "So, you think he's hiding something?"

Nezu nodded slowly. "Oh, absolutely. The records we have, while flawless on the surface, feel manufactured. It's like we're looking at a painting rather than a photograph of his past. Whoever made this background for him was very thorough. I have to commend his foresight, but there's still one thing that stands out."

"What's that?" Snipe asked, his voice cautious.

Nezu chuckled softly, his small paws clasping together. "His background is too clean. It's almost clinical, like he was trying too hard to be seen as a legitimate billionaire. It's a common mistake for someone lacking experience in creating a backstory."

A low murmur spread through the room as the implications set in. All Might, standing near the corner with his arms crossed, finally spoke up. "So, is this meeting just to talk about Kazuya's finances, or is there something more?" His voice, even in his weakened form, held an air of command that brought everyone's attention back to the real issue at hand.

Nezu's gaze shifted from the check to the files detailing Kazuya's recent visit. "Kazuya's wealth and background are important, but they're not the main concern. What's more critical is what he discussed with me regarding Eri's quirk, 'Rewind,' and the potential danger it poses."

He went on to explain, recounting the conversation he'd had with Kazuya. The room grew quiet as Nezu described Eri's quirk and the devastating effects it could have if left unchecked. He detailed Kazuya's request for U.A. to enroll Eri, not for the hero training, but because U.A. was the only place that could handle a quirk of that magnitude and danger.

"It's a risk, but it's also an opportunity to help a child in desperate need," Nezu concluded, his voice gentle yet firm. "Kazuya is doing everything he can to protect his sister. It's clear he's willing to go to extraordinary lengths for her safety."

Midnight, who had been listening intently, felt a strange mix of emotions swirl inside her. The image of Kazuya—no, Mr. Multibillionaire Kazuya—kept flashing in her mind. But instead of feeling resentment or skepticism, she felt... admiration. He hadn't flaunted his wealth, hadn't tried to buy their favor. He had only spoken about keeping Eri safe, about finding a way for her to control her quirk without hurting herself or others. His determination was the kind of raw, honest emotion that was rare even among heroes.

All Might nodded slowly, his eyes thoughtful. "It's not often you see someone willing to go so far for another person. Especially a sibling. But Kazuya... his willingness to invest so much—of both his time and money—shows just how serious he is."

Cementoss, who had been quiet until now, spoke up, his voice steady and measured. "I have to agree. There's something admirable about his dedication. He didn't come here for our approval—he came to do what he thought was best for his sister, regardless of what we thought of him."

Aizawa's eyes narrowed. "That doesn't mean we should let our guard down. Just because he's dedicated doesn't mean he's trustworthy. There's still too much we don't know about him."

"I'm not suggesting we ignore the unknowns," Nezu replied calmly. "But we must also acknowledge the lengths he's gone to protect Eri. His concerns are valid, and I believe it's in everyone's best interest to offer our support."

The conversation shifted back and forth as the teachers discussed the logistics of Eri's enrollment. They all agreed that Eri's safety—and the safety of the other students—had to come first. Plans were made, curriculums were brainstormed, and contingency measures were set in place.

However, the topic inevitably swung back to Kazuya himself. Aizawa wasn't the only one who felt wary. Even Present Mic, usually more carefree, voiced his concerns.

"Look, I'm all for helping Eri," Present Mic said, his voice uncharacteristically serious. "But Kazuya's still a wildcard. We don't know what he's capable of, and if his quirk really can create monsters with abilities..."

"That's precisely why we shouldn't provoke him," Nezu interjected, a strange excitement gleaming in his eyes. "If he can truly create such creatures, I wonder if he could—"

"Nezu, no," Snipe said firmly, already sensing where this was going.

Nezu's whiskers twitched with delight. "But just imagine—what if he could create a creature with intelligence matching mine? Oh, the challenge it would present!"

The room fell silent, and a collective shudder passed through the staff. Midnight rubbed her temples, muttering under her breath, "Great, now I'm going to have nightmares about mini-Nezus running around the school."

"Let's just hope Kazuya doesn't get any crazy ideas like that," Cementoss murmured.

As the discussion continued, one thing became abundantly clear: while the U.A. staff were all united in their decision to help Eri, Kazuya remained an enigma. His intentions seemed pure, his actions commendable, but the unknowns surrounding him left an uneasy feeling that none of them could quite shake.

For now, they would move forward cautiously. But one thing was certain—Kazuya Akiyama was a name none of them would be forgetting anytime soon.

Kazuya POV

Sitting on a park bench with a list clutched in one hand, I glanced down at the bold, familiar titles printed at the top. Naruto, One Piece, Attack on Titan, Fate/Stay Night, Bleach—every anime and franchise you could think of was on there, each one a doorway to a new reality, a new set of challenges. My curiosity was eating at me, the urge to dive into a different world clawing at the back of my mind.

"Man, I gotta chill," I muttered under my breath, flicking through the list. It was like an itch I couldn't scratch, the need to experience a new reality messing with my head. I'd been so focused on surviving and protecting Eri that I'd almost forgotten what it felt like to satisfy my inner otaku. The idea of fighting ninjas in the Hidden Leaf Village, or sailing the Grand Line alongside the Straw Hats... it was tempting as hell. But there was a catch.

I glanced up from the list, my gaze shifting to Eri. She was busy playing tag with a group of kids on the grassy field, her laughter echoing through the park. There was a wide, genuine smile on her face—something I never saw in the original canon. Maybe it was because I'd intervened so early. Maybe my presence really did change things for the better. For a second, doubt crept into my mind. Was I screwing up the timeline too much? Was I putting her in danger by being here?

I shoved those thoughts into the abyss where all my other anxieties went to die. No point dwelling on what-ifs. What mattered was right now, and right now, Eri was safe, happy, and playing with other kids her age. The world could burn, and I'd still call that a win.

Returning my attention to the list, I ran my fingers over the names of worlds I could potentially explore. I could almost see it—battling Titans, throwing hands with Espada, or maybe even duking it out with Servants in a Holy Grail War. But then I hit a grim realization: If I went to one of these worlds... I'd be abandoning Eri.

The thought made me freeze, the excitement draining out of me like water down a drain. Could I really leave her behind? And if I did, who would look after her? Sure, I could dump her off with people like the Urarakas, but I'd be putting her at risk every time I stepped away. There were too many unknowns, too many variables. I could have summoned a shikigami, sure, but my binds limited them. If something happened to me, they'd vanish after two minutes, leaving Eri vulnerable.

"Damn it," I muttered, crumpling the list slightly. The more I thought about it, the more trapped I felt. Exploring new worlds was my dream, but Eri's safety had to come first. There had to be a way to balance both, but for the life of me, I couldn't think of one.

My brooding thoughts were interrupted by the sound of tiny feet pattering against the pavement. I looked up just as Eri came rushing over, her cheeks flushed with excitement and a wide smile lighting up her face.

"Kazuya-nii!" she called out, holding something behind her back. She looked up at me, her red eyes gleaming with that innocent joy that was impossible not to smile at. "Look what I made!"

She revealed her creation with a flourish—a small, delicate flower crown, its petals carefully arranged into a perfect ring. She beamed up at me, waiting for my reaction.

My heart did a weird flip. This kid, I thought, shaking my head with a grin. "Did you make that all by yourself, squirt?"

Eri nodded eagerly. "Uh-huh! It's for you!" She held it up, standing on her tiptoes to reach my head.

"For me?" I laughed softly, lowering my head so she could place the crown on top. "What's this, Eri? Trying to give me type 2 diabetes with all that sweetness?"

Eri giggled, her laughter like tiny bells ringing. "No, I just thought it would look good on you!"

I touched the flower crown lightly, making a show of examining it. "Well, I gotta say, this is some top-tier craftsmanship. Are you sure you're not a professional flower crown maker or something?"

She laughed again, shaking her head. "No, silly!"

"Could've fooled me," I teased, reaching out to ruffle her hair. "You're way too cute for your own good, y'know that?"

Unbeknownst to me, a few of the single moms in the park were watching us, their eyes softening at the sight of our interaction. I could feel a few stares here and there, but I ignored them, focusing on Eri's bright, happy face. She really was a little bundle of joy, completely oblivious to how much she was tugging on people's heartstrings.

We ended up spending a few more hours in the park. Eri was running around, playing with the other kids while I kept an eye on her. It was nice. Peaceful. And for a moment, I let myself relax, enjoying the calm afternoon. Eventually, as the sun started to dip lower in the sky, we decided to take a walk through the city.

The streets were busy, filled with the usual hustle and bustle of daily life. Eri's tiny hand was clasped in mine, and we chatted about the things we'd seen in the park—flowers, bugs, the usual kid stuff. But as we continued walking, I started to get that feeling. You know the one—the one that tells you something's off. I glanced around casually, trying not to tip off Eri.

My eyes narrowed as I picked up on it. We were being followed. A lot of people, too. At least thirty. All of them were moving in sync, like a coordinated unit. The way they maneuvered through the crowd, keeping their distance but never losing sight of us? Definitely not amateurs. Great, I thought dryly. Who are these clowns?

I forced a smile, glancing down at Eri. "Hey, squirt, wanna play a game?"

Eri's face lit up. "A game? What kind?"

"A super fun one," I said cheerfully. "But it's got rules. First, you gotta close your eyes and keep 'em closed until I say so. Can you do that?"

She nodded eagerly, squeezing her eyes shut. "Like this?"

"Perfect," I said, gently scooping her up in my arms. "Now, hold on tight."

With Eri's face pressed against my chest, I glanced back, confirming that our pursuers were still on us. Time to shake things up a bit. I maneuvered through the crowd, taking turns and doubling back until I spotted a narrow alley leading to a parking lot. I slipped inside, ducking out of sight. If these guys wanted to catch us, they'd have to come to me.

I waited until I could hear the hurried footsteps of at least half a dozen of them pouring into the alley, then I took a deep breath and activated Snatch.

The world flickered, and I reappeared behind them, Eri still in my arms. They hadn't noticed me yet, all their eyes focused forward. The suits, the earpieces—yep, they looked like a bunch of dime-store secret agents.

"Well, well, well," I drawled out, causing every single one of them to stiffen and turn. "If it isn't the worst Men in Black cosplay I've ever seen."

The surprise on their faces was almost comical, but I wasn't here to joke around. My voice dropped to a low, menacing tone. "Who the hell are you guys, and why are you following us?"

Their eyes flickered between each other, but none of them made a move to speak. Annoying. I shifted Eri in my arms, keeping my tone calm for her sake. "I'll ask one more time: who do you work for?"

No answer. Just tense silence.

Thirty guys in suits, all wearing the same "we mean business" look on their faces, and not a single one of them willing to spill the beans. I narrowed my eyes, sizing them up again as I tried to place who they could be working for. HPSC was out of the question—no way they were part of that group since I'd already taken away the free will of every higher-up in that organization. Unless every last one of them had suddenly dropped dead, these dudes had to be from somewhere else.

All For One? I quickly shot down the idea. Nah, that wouldn't make sense either. The way these guys were dressed—clean, polished, almost too professional—didn't fit All For One's MO. That guy liked to send small-fry thugs to handle his dirty work, just enough to provoke a reaction. If he really wanted to have a word with me, he'd have rolled up with some crusty back-alley rejects.

So who the hell are you, really? I clicked my tongue in annoyance, the sound echoing off the empty concrete walls of the parking lot. "Alright, screw it," I muttered, eyes hardening. "One more time. Who do you work for?"

My words barely hung in the air before they all lunged at once, trying to dogpile me and Eri like a bunch of mindless drones. The move was sloppy—desperate, even. I reacted instinctively, activating Snatch. Every single one of them froze mid-air, suspended in place like a bunch of mannequins caught in a photo op.

"Idiots," I muttered, glancing down at Eri to make sure she hadn't noticed anything. Her eyes were still squeezed shut, just like I'd told her. "You really think you can take me down like this?"

They stared at me, expressions locked in confusion and a hint of panic as they tried to move and failed. Realizing I wasn't gonna get any answers this way, I decided to up the stakes. With a flick of my fingers, I snatched away their ability to speak, leaving them mute and more terrified than before.

But then something caught my eye—an odd glow starting to pulse beneath their skin, spreading outwards like veins of light. Oh, hell no. My instincts screamed at me, and I quickly traced the source of the energy.

Suicidal attack, I realized, cursing under my breath. "Really? You're gonna blow yourselves up with a kid here?" I didn't waste time. With another Snatch, I ripped the energy core from each of their bodies, temporarily storing it within my own curse energy. The glow vanished, leaving them blinking in confusion. Their faces contorted in bewilderment, probably wondering why they were still breathing.

I wasn't in the mood to play nice. Stepping forward, I reached out with Snatch again, this time targeting one of their minds. Brute force usually wasn't my style, but I was done playing around. As soon as I made contact, I felt a flood of voices—fragmented thoughts, scattered memories, orders given in rapid succession.

"Observe them from a distance… No need to engage… Just gather intel on the boy and the girl—"

My head jerked back slightly. What? They were just supposed to be watching us? Then why the hell did they switch gears and try to kill us?

I pushed deeper, sifting through the jumble of thoughts. And then I found it—a clear directive from a high-ranking officer.

"If he resists… neutralize him at all costs."

Neutralize, huh? I let out a low, humorless chuckle. They must've thought they were dealing with some random kid. But the voices didn't stop there. I kept pushing, my head buzzing with snippets of conversations, meetings, and encrypted messages. A name floated up to the surface of my mind.

Meta Liberation Army.

I almost dropped the guy in surprise. The Meta Liberation Army? That name carried some serious baggage. Ideology-obsessed lunatics bent on spreading the message of quirk supremacy. So, they were the ones keeping tabs on me and Eri? I felt a surge of irritation flare up inside me.

Great, more idiots to deal with, I thought, mentally cursing them out as I edited down the more colorful language in my head for Eri's sake. If it weren't for her, I'd be calling these clowns a whole lot worse than idiots.

Just then, Eri's voice piped up softly, cutting through my thoughts. "Kazuya-nii? Can I open my eyes now?"

Panic shot through me. Crap, almost forgot. "Uh, not yet, squirt!" I said quickly, forcing a smile even though she couldn't see it. "Just a few more seconds, okay?"

I needed to wrap this up. Fast.

Turning back to the immobilized men, I let my gaze travel over their terrified faces. "You guys really made a mistake coming after us," I said softly, my voice dropping to a cold, almost whisper-like tone. "I don't know what you thought you'd accomplish, but... you're gonna regret it."

With a dark grin, I activated Snatch again, diving deeper into their bodies. If they wanted to play dirty, I'd show them what it meant to cross a line. I grabbed hold of their sense of time and mobility, locking them in a frozen state of perpetual immobility. A cruel punishment? Maybe. But it was well deserved. With a snap of my fingers, I set them up in a state of constant explosion—suspended in the very second before the blast went off, locked in a cycle of endless detonation that never came.

I didn't stop there. I felt my smile widen as I pulled every trace of air from their lungs, leaving them unable to breathe. And with another Snatch, I stripped away their ability to see, their eyes now forever blind

"Enjoy your stay in hell," I muttered darkly, before deciding I'd give them a parting gift. Like what I did with Chisaki, I took away their sense of time and freedom. Every second for them would feel like years. Let them stew in the same despair and hopelessness Chisaki felt.

I shot one last glance at Eri, making sure she was still holding on tightly before I triggered Limitless and launched us skyward. The ground blurred beneath us, the buildings shrinking into tiny dots as we shot up past the clouds, leaving the parking lot far, far behind. I couldn't risk leaving any trace, so I wiped every mark of our presence from that place.

Once we broke through the stratosphere and reached the upper atmosphere, I finally came to a stop. The air was thin, crisp, and the world below shimmered like a sea of stars.

"Okay, Eri," I said softly, the anger draining out of me as I looked down at her. "You can open your eyes now."

She blinked them open, gasping in awe as she took in the view. "Wow…" she breathed out, her tiny fingers gripping my shirt as she looked out at the world spread beneath us. "It's so pretty…"

"Yeah," I agreed, smiling at her reaction. "This is the top of the world, squirt. Wanted to share the view with you."

She was too busy gazing out at the shimmering city lights to hear me, her eyes wide with childlike wonder. And that was fine. She didn't need to know what I'd just done or who I'd just dealt with. All that mattered was that she was safe and happy.

But in the back of my mind, the gears were already turning, planning out my next steps. The Meta Liberation Army had made a serious mistake coming after Eri. And I wasn't going to let it slide.

You wanted to play games with us? I thought darkly, my gaze shifting to the horizon. Fine. Let's see how you like it when I decide to play back.
