A device sits in a corner, beeping periodically. The beeps start to gain in frequency as warning labels start to buzz, gauges going out of control. Eventually, energy starts to leak out of the machine, before EXPLODING! A figure came out. as a being of pure fluctuating energy.

Hey there everybody! I'm sure you're wondering about my new name. Well, it all starts with discord, a chat site for gamers. Long story short, I joined a cult and met a co-writer. Give it up for Crystalquill! (Shows no one) ... oh right, i'm just doing this now ... i'll introduce you latter.

Anyway, our fic is based off another one called Hero Class Civil War. She had the original idea with 2 chapters. After that, I joined the server and offered her ideas. She liked, and made me a co-writer.

So this will be cross posted on her Ao3 account. Because it won't give it to me. So enjoy 6 new chapters!

When Iida Tenya had heard UA's intruder alarm for the second time in his life, he expected a villain assault, or the press again, or a misfire or a diversion for something else, but he hadn't expected this.

The group of people huddled around in UA's green plains looked exactly like the people around him. He could see All Might's distinctive form standing out among the crowd, Present Mic's voluminous hairstyle peeking out from the back, and, after a few seconds, he saw himself in a fighting stance, giving orders with chopping motions.

As he was instructed to go to his homeroom, he saw principal Nedzu walk up to the confused mass of people and begin a conversation.

'Things never stop happening around here, don't they?', he thought as he ushered his classmates with Yaoyorozu's help. '"Plus Ultra" indeed'.

Aizawa Shota stood in the normally bright Principal's Office, now sunk in shadows. The metal shutters had fallen in response to the alarm and nobody had risen them after, mostly since the threat hadn't passed.

The two Nedzu's (and if that wasn't ominous, Shota didn't know what was.) smiled at each other from opposites sides of the desk. Shota's own counterpart slumped in a chair, his eye-bags a few shades darker than his own.

"This is a very peculiar circumstance!" began Nedzu, the one from his own UA, cheerfully.

"Indeed," the other one responded, swirling his cup of tea. "It was certainly strange to find a Timeline Quirk, much less for it to be capable of transporting so many people at once. Then again, this year has the propensity for getting into very interesting situations," he said, then took a sip from his tea.

Shota –not him the other one– snorted inelegantly and a fond smile played on his lips. Shota was inordinately attached to his class, that he knew annoyingly well, but he didn't show it. He had absolutely no idea why the hell his double did, and the amount of unanswered questions he had edged him closer to a violent headache.

"He's telling the truth," said Detective Naomasa through the telephone call. It was very convenient his Quirk worked through speakers.

"Well, if that's the case, we need to find out what's different!" Nedzu, his Nedzu– That was going to be annoying. Enough with that. Given names for those of his timeline, last names for the people from the other timeline, at least until a better method is found.

Both Nedzu and Nezu climb up the table and start talking inhumanly fast-paced, so fast it almost sounds like chitters or squeaks. That is something Shota never wants to hear ever again.

He moves to unfold his emergency sleeping bag and catches the stare of his counterpart. He pauses, both staring into each other's eyes, not unlike the staring matches his cats have with each other.

"YOOOOO SHOTA!" screams Hizashi, making both of their heads swivel to him. He doesn't even blink at the double-stare and continues forward to sling an arm around Shota's shoulders. "There's two of you now!"

"I noticed," he grumbles back, but he curls himself a little toward Hizashi's warmth. He can feel himself relax little by little, and Yamada goes to curl up with Aizawa too. 'At least that hasn't changed between timelines' is his last thought before he starts dozing.

…

"May I have your attention!" calls Nezu after an unfairly short time, the murmur of conversation that hadn't been there before stopping abruptly. Shota doesn't move or open his eyes, but his training refuses to let him go back to sleep. The Principal seems to know this because he continues regardless of his state.

"We have found the divergence!" he says before pulling up a few records up on screen. "Our curriculum included an activity called "Hero Class Civil War" in the months between the internships and final exams, but it was scrapped after a few iterations to leave more time for the students to prepare for the exams. I believe it was around your time, All Might?"

"Yes it was!" he announces, obviously trying to imitate how his voice boomed before losing his Quirk. He more or less manages it, but not without coughing noisily and spitting blood. "I remember Todo– Endeavor was very disappointed he could not fight in his third year!"

Shota expects some inane commentary over this, and he gets it from the people in his timeline, but those from the other timeline remain suspiciously silent.

"Oh," says Vlad King. Kan doesn't elaborate what he meant by that. No one from the other timeline says anything back.

Shota prizes his instincts, he has spent most of his life listening to them, like every logical Pro Hero should. Right now, they are pointing out Yagi's slight pallor, and Nedzu's a-little-too-wide smile.

He sees Aizawa's face flash through a thousand different emotions. Pride, doubt, disappointment, nervousness…

Just what the hell happened?
