The Last || My Hero Academia X Demon Slayer

After he got the kids out of the bus, the damn brats had been too loud for him to sleep, which was a first, Thirteen had been waiting outside for them.

"Hello and welcome to the USJ!"

The students started freaking out that they were here, and when Thirteen opened the large doors the excitement only grew.

"It's as big as Universal Studios Japan!"

"They have a whole boat in here!"

"How big do you think the letters for the fire room are?"

"Hey before we go in there is something I need to say, maybe two, no three or four- anyways..." The kids sweatdropped. And with that Thirteen showed their quirk and started a quick speech. "Flood wrecks, landslides, fires etc. This is a practical training area I made to simulate them all, it's the Ultimate Space for Jams!"

"Thirteen."

"Right, to the important things. I'm certain you're all quite aware but my quirk is called "Black hole." No matter what material may be sucked into it's vortex I'm afraid it will turn into dust. It is also a power that could also easily be used to kill people and in that way it's no different from the quirks of everyone here." Problem Child #2 glanced to Problem Child #1, which did not escape Todoroki's watchful gaze. "Naturally in this society of superhumans, quirks are strictly regulated and the requirements for their lawful uses are strongly enforced. We can tell at a glance that that is the makeup of this current world. That being said, please don't forget that each of you possesses a quirk that can go awry. One wrong step is all it takes to be able to kill others accidentally. During Aizawa-senpai's tests you learned of your respective powers' true potential and during All Might's Battle Trials I think you took away a true sense of the danger of brandishing those powers against one another."

Most of the staff by now, except the ones that would come later in the year for second and third years, had learned what happened during the battle trials. A tech issue had caused students to be in a potential deadly situation as most of the staff had been told about Problem Child #2 and how he shouldn't really be partnered with Problem Child #1.

Problem Child #1 seemed a bit out of his depth in the beginning of their speech, but after he nodded his head with each thing they said.

Problem Child #2 was just watching the green haired boy, but when the boy flinched ever so slightly, Shouta couldn't help but notice the gaze flashed guilt for a split second. Problem Child #1 had maneuvered around Todoroki so that the taller boy was in between him and not only Bakugou but Thirteen too. The poor kid looked honest to jelly packets scared about people just using their quirks willy nilly. Something Shouta is going to have to tell Nedzu later.

Thirteen turned to him and he quietly walked to them, raising a three when they asked about All Might.

Then, when Thirteen had been leading the kids in the dome, the doors slammed shut and a dark mist filled the middle. From there dozens of villains walked out. The kids behind him started panicking. Among Yaoyorozu and Todoroki outwardly surprised, Problem Child #1 started fidgeting, not scared fidgeting, but anxious fidgeting. He looked sick and fortunately because he was so surprised, Todoroki grabbed his arm to ground himself, probably not even noticing Problem Child #1 relaxed when he did so.

As more villains filtered through, they only got bigger until they mist shrunk to form a more humanoid form. The last person through had light blue hair and disembodied hands on his body.

There was a pro to this. Because he didn't need to lead them around anywhere, he had slipped into a spot just behind Problem Child #1 and Todoroki. Due to this, he could hear the light murmuring that was coming from Problem Child #1, quiet analysis on the intruders, only really catching parts of it. "I have to get back for the Ubuyashiki twins... the alarms aren't going off so there is probably a quirk blocking them... the mist guy has that brace so... perfect timing on their part... likely trying to fish someone out... kinda like the Headgear guy's quirk today... hair bullets... school is like 3km away..."

Todoroki, after hearing his new more-or-less friend turned, looking for Shouta. Once he found the man, he simply got a nod in response. Shouta walked ahead of them, "Stay with the group, Problem Child, you could have mentioned you analyze too."

Problem Child #1 blushed, or at least as much as he could in the situation. "Oh I haven't done it in a while-"

"Stay with the group, don't get hurt, don't get yourself targeted." With three whole pieces of wisdom he leaps down the stairs to buy time for his students.

Nevermind, the students aren't doing anything, which would be good in literally any other situation, the mist guy is with them and there might be a bit too many thugs for him to handle. Thanks to what he picked up from Problem Child #1 he had quickly sliced through them like butter, specifically targeting anyone who looked like they might even have an electricity quirk. The what-appears-to-be-leader had been standing mostly in one spot, watching him. Shouta was getting tired. Yes, he was an Underground Pro Hero, but he always had some form of backup, here he couldn't radio for shit.

Because the lights were somehow still working, he had to keep jumping around so no one would notice his hair. He had taken down about half of them and somehow the hand villain pinned him down.

He was trying so hard to struggle against the relatively small adult when the weight lifted off of him and he had barely a moment to look and see... his student. Scared out of her mind staring at the hand guy. His shoulder and elbow were in so much pain and he had only forced that out of his mind when he felt a chill on his neck. He hadn't been shot by anything and he was doing well in canceling only the quirks he needed to as to not strain himself, but there was an unmistakable chill on his neck that was oddly... resurring.
