Here's another upload, gonna be honest beyond the base concept of Izuku having zanpakuto I haven't really put much thought into this story, over the last few days I've been crafting up a system for how this world works compared to canon. Hope you all enjoy!

Wednesday 12:30 pm

"Uraraka, for the last time you don't have to pay me back!" Seriously it wasn't even that much money, just 15,000 yen, barely a dent for my daily expenditure. That didn't do much to dissuade his new friend however.

"That doesn't make it any less wrong! And call me Ochako, it's the least I could do after everything Midoriya!" I sigh in minor frustration while the others in our class look on with varying degrees of amusement on their faces. 'Traitors'

"Fine, but only if you call me Izuku, it would be weird if only one of us did it." That smile of hers is a dangerous weapon. Will I ever be able to resist it? Only time could tell.

"As entertaining as this is, it's time for class." Aizawa spoke up as everyone sat down, still a little on edge from our first day. "Today we will conduct rescue training, the teachers that will be supervising you are All Might, myself, and a one other that you will meet at our destination.

Seeing his class' growing excitement Aizawa sent them a light glare before continuing. "It's up to you whether or not you wear your costume. As some are ill-suited to this sort of activity. We'll be taking a bus to our destination so get dressed and hurry out. That is all." Succinct as always Aizawa walked out leaving us to our own devices.

I decided to take my costume with me, it was pretty useful after all, even if it didn't look so aesthetically speaking. The whole thing was water proof and flame retardant, it was also insulated against electricity which made it a nearly perfect general use uniform.

On our way to the bust Iida raised some concerns over the bus' seating order but I deflected by saying that it was an open seated bus. That guy did too much sometimes, at least he was consistent. Taking my seat next to Tsuyu and Yaoyorozu who decided to join me, along with Ochako, Ashido and Kirishima who was sitting across from us we started up a conversation.

"So Izuku, I've been wondering why do you call your swords zanpakuto?" Tsuyu asked in her usual blunt way, it was a fair question and I planned on answering...As soon as Tokoyami stopped chirping over the name several seats over.

"A good question, and to be honest I came up with that name years ago so you can blame middle school Izuku for that one. The way I came up with it was from the testing stage of my quirk. You see my blades were being tested to see what they could and could not cut and along the way someone with an intangibility quirk, named 'ghost' came along...You can probably tell where this is going." Poor guy, he was way too confident with his ability and ended up with a sword in the stomach. At least he still got paid.

"Ouch, did he survive?" Kirishima asked in sympathy, infinitely more cautious of any blades he sees in the future. If those things could cut through a ghost..Then what about a rock?

"Oh yeah he was fine. Just a minor stomach wound that was patched up easily enough." A few lt out breathes of relief at that. "The same can't be said for the poor bastard that tested out Hyorinmaru. The ice still hasn't thawed to this day." A quick reminder of the dangers of my blades, I really needed to drive that point home before anyone got any ideas.

"Right right, you're blades are uber dangerous and can kill us in an instant, we get it. When are we gonna be able to try 'em?!" Kaminari asked, a little pale but still ecstatic over the idea of using one.

"Soon enough I guess. Some of them are actually pretty useful for rescue operations so it might even be today." At that Aizawa told us to be quiet and that we had arrived. Stepping off the bus we entered an absolutely huge building, honestly it was more like a small town than anything else. And inside this building was what I could only assume to be our teacher.

"Floods, landslides, conflagrations! Any disaster or accident you can imagine! I built this facility myself I call it… The Unforeseen Simulation Joint. Or the USJ for short!" Huh, I just got a major feeling of deja vu. Oh well it was probably nothing, this new hero though did strike me as familiar, but what was her name again?

"Thirteen! She's really here, my absolute favorite hero!" Ah that was her name. And she was Ochako's favorite hero huh? Makes sense given the space theme, though their quirks are total opposites. An offensive gravity based quirk that works at range and a utility anti-gravity based quirk that works via touch.

Thirteen went on to talk about how some quirks were dangerous and how they could be used to kill. Which was why we were having this exercise, both to learn how to save people during disasters and to learn when to not use our quirks.

Or at least that's how this day would have gone if not for my E-class luck. A black cloud appeared at the center of the huge building. A very familiar black cloud. A black cloud that made me very, very angry. Though a quick look from Aizawa calmed me down somewhat as I took a look at our situation.

'30-50-70...Nearly 80 villains, most of them barely look like they know how to use their quirks let alone fight.' I thought, confident in our classes chances against them. But those three in the back, that black could villain with a teleportation quirk. They were serious villains.

"Eraserhead, permission to join you? I can provide long range support but I recommend that you don't take your eyes off that warp villain that's the one that attacked me a few years back!" Stopping for several seconds Aizawa nodded eventually.

"...Fine, but don't you dare leave this area, and I'll keep the warper in mind but I'm sure you already know my quirk's weakness." Yeah, dry eye. An annoying weakness but it was manageable. I had a way to keep the warper distracted while Aizawa recharged.

A new blade appeared in my hand, this one all but radiated a chilling cold. Looked like a regular, if slightly large katana at 1.4 meters long, the guard was in the shape of a four-pointed bronze-colored star, a light blue hilt hinting at its ability.

"Tsuyu, apologies in advance but right now I can't afford to hold back. Bankai! Daiguren Hyorinmaru!" Tsuyu, who was confused at first, immediately understood why Izuku had apologized. After calling the release phrase his body, and the surrounding area was bathed in true cold, and ice. So cold that the very water vapor in the surrounding area froze instantly.

"I can't leave the area, but Aizawa never said I couldn't gain some altitude!" I smirked a bit and did just that, flying above my classmates to gain a bird's eye view of the battlefield. From there I did the only logical thing that I could do in this situation.

"Sick em!" I launched a goddamn ice dragon at the center of the gathered villains, internally releshing the Wilhelm screams that came soon after. Of course they didn't all get hit, the guy in the center with the hands in particular somehow...Rusted? The ice away before it reached him while the big black brain bird just punched it away.

'This might be more difficult than I thought.' Some kind of disintegration quirk and super strength. Maybe hyper durability too considering his body. Both were very powerful, particularly the brain villain who just punched several meters of ice to pieces. 'Big bird is my top priority, he clearly has a mutant type quirk so Aizawa can't do much and Thirteen isn't a combat hero so she's out too.'

Testing the waters a bit I pull out a second zanpakuto and wield it with my off hand, let's see how the big guy deals wi- "Begone! Writhe in torment!" A circular mist appeared around me, I cursed as I was transported to what I could only guess was the conflagration zone. Given the burning buildings and such.

'The fool probably thought that all the heat would melt my ice. Jokes on him.' Taking a quick look around I noticed one other person in the area, Ojiro was standing in a fighting pose as he was surrounded by about 10 or so villains. 'Time to lend a hand. Or a giant ice dragon projectile as it were.'

"...I could have taken them." Ojiro says after a moment of hesitation as he looks at the frozen wasteland where a burning city used to be.

"I don't doubt that but time is an issue here. Would you like a ride out of here or are you ok?" I reassured and offered him, forgetting a tiny little detail.

"I'd rather not get frostbite. Thanks for the offer though." Right, forgot about that for a moment. My wings were also pretty sharp so that was probably for the best. Speaking of wings.

"Right, I should probably switch out of this form, not only does it drain my stamina but it could hurt some of our own people as a side effect." I deactivate Hyorinmaru, letting it fade into the aether. In it's place is one of me least popular blades.

"Bend them to our will, Minazuki!" Least popular, but easily one of my favorites. It had everything! Flight, size, durability, energy efficiency, healing abilities, intimidation. And all with just a shikai! I wasn't even using a 1/10th of the energy that I used for Hyorinmaru now.

"How about now? Or are you also freaked out by the flying slug demon?" I asked Ojiro who gave me a deadpan stare. "Fine. See you next chapter I guess." I honestly didn't know why people hated Minazuki, it was so cute! Just look at that single bulging eye, it just looked at you with a childishly innocent stare.

'It's probably the lime green color.' Regardless of all that I still had a job to do. First off I needed to find the rest of my classmates and either help them with the villains or clean up after their fights while offering transport.

'So Todoroki's done with his side, he should be fine on his own though I pity the villains. Those three in the mountain zone were doing just fine. The flood zone though...I'll go there next.' Tsuyu and Mineta were standing on a boat while being surrounded by water type villains. I was going to go for a somewhat stealthy, humane approach...Until one of the villains cut the damn boat in half with a water jet, now time was of the essence.

'I can save them but it will be messy...Wait why am I hesitating these are literal villains attempting child murder.' Ah, another benefit that Minazuki allows me is that it doesn't need me to wield it in order manipulate the creature. Which means:

"Pierce, Gonryomaru!" You all know the deal by now, a regular katana appears only to transform into a rapier. At first nobody knew what to make of this until I straight up toss it at the lake below. Gonryomaru was a lightning type zanpakuto, capable of changing the weather with it's bankai. You do the math.

15 or so cooked villains later and an awkwardly quiet slug ride later and we drop down near the shore of the flood zone. "Sorry you all had to see that, I didn't have many other options to take them all out while saving you and I needed to act quickly." And frankly it was the most humane option too. I personally don't want to know what a Ryujin Jakka thrown into a lake would do to the human body within said lake.

"D-did those villains just d-die." Mineta managed to stutter out, eyes a little empty from the earlier screaming from the villains. Poor guy, Tsuyu was stoic as always but she was also staring into the distance so I could only assume she had similar thoughts in mind.

"Most likely, I'm sure some of them survived but the one's wearing scuba gear are likely not coming back up. Again I apologize but we don't have time for this, big bird All Might is currently beating the life out of our teac-" Aizawa's body landed close to us in a heap, elbow eroded away and limbs bent at odd angles.

"...Right. That. You two might want to run I don't think I can hold back against that thing and most of my blades aren't the dictionary definition of environmentally friendly." Picking up Aizawa I placed him on top of Minazuki, never once looking away from the big three villains I commanded the slug to fly the three towards the entrance of the facility.

3rd Person Fight POV

Of course it wouldn't last very long, that distance was far larger than the safe radius that Izuku's copies could go but it should survive long enough to at least reach the stairs. Now for the villains, and it seems that the living cloud recognized him.

"Be careful with this one Tomura Shigaraki, he's dangerous even compared to a pro like Eraserhead. I fought him once before and he forced my retreat." He warned his partner? Leader? It was hard to tell since the big guy apparently also took orders from Shigaraki.

"That was flattering but it won't stop me from cutting you apart limb from limb and sending you to the deepest pits of tartarus myself… Oh! I'm sorry, I'm usually far more composed. It's just that my mother was in that building so I'm a bit absolutely livid!"

"Indeed, and with that display you gave us earlier you've definitely earned your title as the hero world's shinigami. But tell me, what is a god to a non-believer? Kill him Nomu!" The hulking beast took a moment to process the order before it launched itself at the green haired swordsman, a new blade appearing by his side as this happened.

Then Shigaraki's vision was engulfed in flame as the two pieces of Nomu's bisected body landed behind Izuku. Flaming blade in hand as a ring of fire surrounded him and the rest of the central plaza. Izuku's green eyes nearly glowing as he uttered the words "Do you believe now?"

Was that overly dramatic? Perhaps. Was it badass as fuck? I'd like to think so. Anyways here's the fabled fourth chapter of a series that I'm having a bit of trouble writing for, as you can see shit got real quiet quickly and I'm going for a bit more of a dark realistic setting compared to canon. Villains and heroes can and will die by the whims of storytelling and chance, and not just the fodder ones either. I just want to clarify that ahead of time.

Well that's all for now, I hope everyone enjoyed it and I'll see you all next time. And as always, have a great day!
