The world is an incredibly troublesome existence. Whether it be by the hands of man or nature, there were numerous occasions where idyllic scenes were torn apart by disaster. Towns ruined by flame or flood, villages shattered by earthquakes, kingdoms starved by endless snow – civilisations could easily be brought to their knees when these tempestuous events occurred. Even in the age of heroes, being faced with such environments could result in ruin without proper handling.

Despite this, young heroes-in-training received woefully little preparation for dealing with these disasters. With many choosing to focus on combat skills and strategy, there simply wasn't the time nor the resources to do so. Uncommon as they were, many of their students wouldn't face one for the majority of their careers; what was the point? Even Yuuei had fallen prey to the mindset and if they didn't care, what reason had any other hero academies? It wasn't until one particular teacher met the lack of training by forging their own Unforeseen Simulation Joint that the idea of educating students in how to handle disasters was considered of importance.

"Well, I can't say I can relate. O-50 is an incredibly mountainous planet. You'd be hard-pressed to find a community that wasn't built on or close to one." Gai remarked as the world sped passed them, Tetsutetsu serving as a wonderful wall protecting Izuku from the antics of Kosei and Setsuna. With their teacher so hastily piling them into the waiting buses, there hadn't been much time to plan out who sat next to who. Regardless, Izuku could hardly complain. Thanks to Tetsutetsu drawing all the attention every time he opened his mouth, nobody cared to notice Izuku mentally chatting with Gai. "If we didn't teach people how to deal with those sorts of incidents, we'd probably have half the settlements that we do now. That's not even considering places like the Land of Light."

"Ah yes, I guess it's a little different for giants…" Izuku replied with an awkward chuckle. What humans would consider catastrophic was barely a spillage in their eyes. Devastating boulders could be destroyed with a flick of their fingers, tempered bodies rending sweltering heats ignorable. If the Ultramen were faced with something they would class as a natural disaster, planets like Earth probably wouldn't survive. "Actually, I'm pretty sure Ultramen could be just as bad at times. Didn't you say Ultraman Mebius practically left a city in ruins during his first fight?"

"Well, we… we don't talk about that." Came the spluttered reply. "Hey, look! Isn't that the building you're meant to be going to! That USJ or something!"

It took less than a second before Izuku was plastered to the window, Gai's tiny sigh of relief ignored as the majesty of the Unforeseen Simulations Joint came into view. With a massive dome piercing the sky, it may have very well dwarfed Yuuei itself. Considering the eclectic combination of environments contained within, it was a necessity. Even so, Izuku couldn't hold back the surprise and excitement in his gasp, emotions mirrored by his peers as they also took notice.

"Usually we'd wait to get you in this place, make sure you have enough skill to handle a normal situation before throwing you in at the deep end. With what happened during your entrance exams though, the Yuuei staff decided it was better to teach you about large scale issues sooner rather than later. You aren't going to be saving anyone if you're crushed under a building after all." Vlad King spoke up, the rowdiness within the bus dying immediately. "That means I want to see you lot giving Thirteen your full attention! Heroes far greater than you have been injured in the USJ through carelessness! This isn't a playground and it isn't someplace where you can mess around with your quirks. Anyone who doesn't treat this as seriously as the real thing will find their asses kicked out sooner than you can blink! That said… Welcome to one of the wildest places Yuuei owns."

If the exterior had piqued their interest, then the students practically exploded the moment that they entered. Imagining the odd combination of environments was one thing, but to personally witness the chaotic combination of flame, frost and fissure was an entirely different thrill. The closest comparison one could draw was a theme park with its enticing combination of themes, yet to call them equal was woefully inadequate. One glance was all Izuku needed to see the anticipation bubbling within his classmates, several already ready to charge in with reckless abandon.

"The expenses require do construct a facility like this… I shudder to imagine it." Turning at Ibara's comment, Izuku could only nod. When you had to add in maintenance cost, the money Yuuei invested had to have been astronomical. "I suppose we're blessed to have access to this. The reasoning behind it, however, is less than reassuring."

"It beats having to stand around not being able to do anything though." The green-haired boy replied, hefting a hastily provided bag over his shoulder. Thanks to how rapidly Vlad King had ushered them onto the buses, there hadn't been time to get changed. Not that Izuku was complaining. Wearing his hero costume was one thing, but being the only one wearing it while stuck on a bus full of people who would constantly comment? It wasn't a particularly nice-sounding scenario. "Even if we can't deal with a giant villain by ourselves, we should at least be able to help people if they get stuck under rubble or trapped in a fire. That feeling of being helpless in front of that villain, nobody should have to feel that."

"Nice acting Kid. A plus for the motivation speech."

"I don't know what you're talking about Gai. I was terrified when that robot showed up. If it wasn't for your presence, I would've been useless." Izuku mentally muttered, his fist tightening around the bag's strap. "That fear though, it's a motivator. It's a reminder that we as heroes shouldn't let anyone else feel the same. The moment we don't feel it is when we stop being human and become an alien to ourselves. That's all well and good when you're here and we can handle these situations, but I can't rely on you forever. No matter how much I want to…"

"So this is class 1-B? Welcome, I've been waiting for you." Gai's response was cut off by a distorted voice, Izuku immediately perking up alongside his peers. Though every hero was distinctive in their own right, there was no way a voice like that could be mistaken for any other. After all, the specially tailored spacesuit required to produce it belonged to one person only. "Allow me to introduce myself. My name's Thirteen, the one people call the Space Hero. The Unforeseen Simulations Joint you see before you is the fruit of my labour. A training ground where several accidents and disasters can be safely recreated; this is the kind of facility you won't find anywhere else. Here you will take your quirks - powers that may very well kill with one wrong step - and turn them into tools that can truly save human lives."

A chill passed over class 1-B as Thirteen uttered those words. For those wishing to become heroes, being reminded of their lethality was one step away from being taboo. Regardless of how true the fact was, anyone would flinch at being told of their capacity for murder. Villains were different, right? Heroes couldn't kill, their quirks were good… right? That was what they had been told their whole lives.

"There was a man named Michel Foucault who said that 'there are moments in life where the question of knowing whether one might think otherwise than one thinks and perceive otherwise than one sees is indispensable if one is to continue to observe or reflect.'" Thirteen continued, whatever reaction the hero held to her students' hesitation obscured by her void-filled helmet. "I understand that's a little wordy, but what it means is that without acknowledging every possibility, we become blind to them. Yes, your quirks allow you to achieve incredible things, but they could very well spill blood with a single breath. Blades that can cut flesh with ease, hands that could crush people to a paste, beams that could eviscerate innocents; if you became villains, you could easily murder swathes before a hero could stop you. In fact, deaths by heroes who accidentally use lethal tactics aren't a small number. By acknowledging that however, you're now in a position to actively avoid it. In realising the true extent of your abilities, you will understand your limits and better find ways to ensure even the most destructive quirks are utilised in safe and beneficial ways. It's my job to help you develop that awareness, and this facility's job to force you to."

For a helmet that showed no face, the sadistic excitement emanating from Thirteen was horrifying.

"Shall we begin then?"

"…How do I look?" admittedly, the entrance to an encapsulated burning cityscape wasn't the best of catwalks. From the noises of interest that those gathered made, however, it clearly wasn't an issue. Whatever embarrassment Izuku had on being the only one wearing a hero costume was dwarfed by that of being the subject of so many intrigued looks. The sole saving grace was that the class had been split between the various zones. That meant only four people were poring over Izuku's form – a minor relief, but a relief nonetheless.

"Wow dude, you look like a robot or something! This thing's crazy!" Manga enthusiastically replied, tapping at the metal with the back of his hand. "Where did you get something like this made? All the good people are usually swallowed by huge companies. Something of this quality should've cost a fortune!"

"The construction is certainly beyond my imagination. I fear my own costume concepts pale in comparison." Reiko continued, inspecting Izuku with such an airy elegance to her movements that she could've been mistaken for a ghost. With the way ashen hair obscured her face and her hands were posed in a unique manner, Reiko was practically halfway there. "Will it not hinder your physicality? Bearing the weight surely must provide a burden?"

"A friend of a friend made it. He's worked with some amazing stuff, I never thought I'd be able to use his creations. It feels more like a second skin than proper armour." Izuku answered as he flexed his fingers, unable to keep himself from nervously glancing towards the gate before them. The durability of the armour was undoubted. Whether it would be able to withstand the incredible temperatures contained within was another thing entirely. "Not exactly the nicest of environments to try it out in, but I had to eventually. It's not as if I'm going to have the chance to get changed if something like this breaks out."

"Nice thinking. I hope that's something you all can take into account when you have your costumes designed." Thirteen's voice piped up. "People always tend to go with the flashy over the practical. Considering how important marketing can be to a hero, it's understandable, but it doesn't make it any less foolish. That's something for you to think about later though. Right now, I think it's time to introduce your first activity."

"My apologies Teacher, but wouldn't it be prudent to await Vlad King's presence? He has seen off every other group." Ibara interrupted without hesitation, eyes narrowed as she bowed her head. Glancing around the USJ, Izuku couldn't hold back his blinks of surprise. For a man of Vlad King's size and presence, his ability to slip away unnoticed was apparently far greater than they gave credit for. With how effortlessly he subconsciously commanded attention, it should've been obvious when he disappeared. Then again, perhaps Izuku's momentary costume change had been distracting enough. "He never mentioned any plans of leaving and it is unlikely he would purposefully choose to exclude us."

"Why, isn't it obvious?" came the far too amused retort from the Space Hero. "Vlad King's currently burning to death, buried beneath the rubble inside."

Any signs of levity died in less than a breath. Whether it was Thirteen's claim or the annoyed yell from within that somehow managed to reach their ears, it wasn't quite clear. Regardless, what had once been a jovial atmosphere soon fell into chaos. If it weren't for Thirteen's bulky form preventing them from moving, the gathered quartet may very well have charged forth without thinking.

"Acting rashly will get you nowhere. The fire zone is currently set to a fire in the rear of the building, meaning Vlad King's safe for now. Whether he remains that way depends on how you choose to move." Thirteen warned. "Your first task is to ensure the safe extraction of your teacher. So long as he's within this area, he will not be able to assist with his quirk. Consider him a civilian. Analyse the situation, formulate a plan and execute it before the danger grows too large. If my calculations are correct, that should give you around ten minutes. In a real fire situation, you wouldn't even have that long."

"Ten m-minutes? How are we meant to scout and form a plan in that kind of time?" Manga burst out, a slight tremble to his body as a massive exclamation mark plastered upon his face. It was only Ibara's hand upon his shoulder that prevented the boy from deteriorating further, the vine-haired girl looking to the doors with a solemn expression.

"We don't have time to waste fretting. We're fortunate that each of our quirks will be beneficial inside. We will not have to adapt to an extent." Ibara stated, a finger absently twirling away at a vine. She shuddered to think about what someone like Shihai would do when the time came; the light produced by fire didn't particularly endear itself to someone who worked best in the darkness. "So long as my hair remains away from the direct flames, they should remain fully functional. I should be able to remove any obstructions that block our path."

"I-I-my quirk is probably best for support. I can fill in broken floor, block stuff from falling… things like that." Manga eventually added, fingers poking together while his face took on an ellipsis. "I'm not the strongest, so I'm probably not best for helping someone like Vlad King out."

"I suppose that is where my quirk comes into play. Though my limit has proven to be an average human's weight, my levitational ability should allow the transportation of our teacher to become markedly easier." As if Reiko's claim was not enough, a quick tap had her body floating just above the ground. "Regardless of whether I'm capable of carrying Vlad King's sizeable frame, two of us working together should provide the necessary power."

"I guess that's where I come in. Leave the fire and the heavy lifting to me. If Vlad King's going to be lightening, I should be able to handle it." Izuku quickly interjected, resulting in a question mark upon Manga. It wasn't entirely unfounded in hindsight. With a quirk that supposedly produced beams, its utility when it came to fire wasn't the most apparent. "Don't worry. I've been learning how to augment my quirk, and apparently, my gear should be able to help it out further. I'll definitely be able to put out the fire!"

"Looks like you've got a plan then!" Thirteen said with a cheer to her tone, hands clapping together. "Well, what are you waiting for? Get in there before you teacher burns to death!"

They needed no more encouragement, the four dashing into the burning area at full speed. Instinctively, Izuku's hands came up to his face, a feeble attempt to block the incoming wave of heat. When it didn't seem to come, however, Izuku could only give a sigh of relief as he looked to his armour. It was just a shame the same couldn't be said for his partners, faces already red… or at least, Reiko and Ibara's were. Honestly, Izuku would've been more frightened than concerned if Manga's had become a similar hue. With a single move, however, that would soon be changed as they were met by a hideously charred wall, flames still licking away at it.

"Well then Gai, let's see if this works." Izuku mentally murmured the blades of the slugger kourin ejecting at just a single touch. The other hand reached down, two cards slipping into fingers that brought them just before the weapon. "Agul-san, Blu-san, I need to borrow the power of your raging tides!"

ULTRAMAN AGUL!

ULTRAMAN BLU!

LIQUID AQUA!

"Izuku?" but Manga's voice would be drowned out by the sound of gathering energy, the slugger kourin taking on an azure hue as Izuku threw his arm back. With the burning wall in front of them, the other didn't have any other choice but to throw themselves to the side, leaving Izuku with the perfect sightline for his move.

"Aquid Healing!" despite the furious swing Izuku gave, the resulting wave of energy held no agency. Sweeping across the room, any fire that came across the azure wave found itself killed in an instant, suffocating heat replaced with a soothing sensation. No longer covered in fire, it was a simple matter to cut down the scorched door, the slugger kourin slicing through the wood and metal as if it were air. "Looks like this thing's more powerful than I thought. Let's go!"

"Found you."

"Izuku? What ails you?" Reiko asked as the green-haired boy paused, his confused expression hidden behind a metallic visage. From the similar looks upon the others, it was fairly certain they too had failed to hear the voice, Izuku giving himself a slight slap on the side of his face. Before he could open his mouth to answer though, the mysterious voice decided to intervene.

"Zetton-kun, Sran-chan, let me borrow the power of your darkness~!"

ZETTON!

SRAN-SEIJIN!

CHOU GATTAI!

ZERAN!

Super hero time! See you next time!
