AN: This is a reupload, the chapter is still the same, I apologize to those that have already read this chapter, but there are improvements to grammar. I'm reuploading this because of the recent FFN problems, and normally in the first 24hs of a chapter this fic gets atleast 500 views, not the 100 it recieved this time. Again. sorry.

She was up to something. She had to be. It was against her nature to just be sitting there taking notes like a diligent student, sure she was competent, and was by all rights a good student - records from her previous bout through the U.A. showed as much - but quiet and still just weren't who Joke was.

Her pencil touched her desk, he spun to glare at her - quirk activated - to find her erasing something in her note book. The rest of his students looked between her and him in a kind of wide eyed fascination. He was going to have a heart attack by the end of the day. He tried to listen to Toshinori's advice, but he could not silence his instincts.

What if this was all just some elaborate prank and she still had her memories? Joke could improvise that quickly the moment she realized she was a kid again. She was just waiting for him to drop his guard, that was it. It had to be! And, and, and.

Holy crap, he was paranoid. Maybe he should start going to his therapist more often. Or actually get out for once, what was Shino's number again? Wait, he was teaching.

The lesson carried on as planned. A few mutterings, but that was normal kid talk and to be expected with the seating order changed to much, it'd be more disruptive to try and quell it. But Joke was just a ticking time bomb of laugher.

Still a few more minutes and it'd be time for the practical part of class, maybe then he'd be able to relax, at least until tomorrow.

A snort into a chuckle tore through the room with the force of a hurricane. He spun to glare at the source, he saw an Izuku with hands clasped over his mouth doing his best not to laugh, while Emi continued to write in her note book. From here it looked like legitimate notes, maybe a few doodles, but nothing out of the normal.

"Sorry sir," Izuku mumbled biting his lip and placing his hands into his lap.

Great, now he felt guilty.

"That's it for lessons, now grab your suits," The magnetic locks came undone, and the students all but shot out of their seats scrambling for their suits. Despite everything they had gone through they were still eager to become heroes. Or maybe they were just excited to get up and move. "Today we'll be doing a different team exercise."

"Finally!" Joke shouted shooting from her seat, and stretching. "We finally get to do something I'm good at!" She turned to him all smiles. "Yo! Eraser-sensei, do I have a suit or anything?"

His whole body tensed in the way that only she could make him. That razors edge between dread and annoyance, sprinkled with respect. He took a breath, she was a student now, at least for the time being. He needed to treat her no differently than the rest. "Sorry, but we don't have costume to fit you so you will have to use the P.E. uniform, however we did manage to recover some of your…. Gadgets from your home if you'd like to take a look at those."

There was a spark in her eye that he knew all too well, her quirk made it easier to use certain gadgets, and when they worked together it seemed like every week she had some new and wacky gadget to demonstrate.

"After class, have Izuku show you to the Development Studio," He scratched his head, Eri had shown no signs of being able to progress things forward, and her control of backwards was still limited, this really was a punishment for letting Mirio and Eri talk him into it. It was probably best he got used to seeing Emi like this.

Shame she was now part of a generation that was staring a dark age in the eyes.

XXXX

"Woah! Your costume might make me so jealous my hair turned green!" Emi, elbowed him in the side. As a class they stood in front of a one of the action areas, a dull brown building loomed in front of them. In addition to her P.E. uniform, Emi had a gas mask hanging around her neck and her hair was held back by and orange bandana that clashed with her hair. "Bwhaha! Oh wait, it's always green!"

A chuckle escaped him, more out of nervousness than anything else. "Uhh, thanks Emi, It's still a work in development, but I think the person that designed it stayed true to my original design."

"I like your face mask," She brought her fingers up to her cheeks and mimicked a smile, "it kind of looks like a smile, does it do anything special?"

"Oh, that's what I was going for originally. But, now it's just a mouth guard, what about yours?" It felt like he'd seen that smile gesture somewhere else before. He stared at her for far to long and tried desperately to cover his blush by putting his mouthguard on. She did have a great smile.

She placed hers on as well, somehow her smile was still visible though her mask opaque. "It's a gas mask! You should see if yours can become a filter as well, it could be useful."

"That's actually a good idea."

"Hey! I know! Take me to the gadget making place after class and you can get that taken care of while I see if they can make me a weaponized rubber chicken!"

Aizawa-sensei stood in front of the class holding single box. Looks like they were doing a team exercise again. But it didn't look like Class 1-B was here, so probably not as extreme as the last time. "Today we will be doing an attack and defend exercise, a group of heroes will be trying to rescue a hostage,"

A T.V. flicked on to reveal a giant All Might Pillow with a speaker tied up in a chair. "Help me! I'm a hostage!"

"You've done something similar to this before, however the situation is different this time, not only do you have to be careful not to harm the hostage, but the villians will out number the heroes." Aizawa-sensei motioned towards the box. "There will be three sets of three to two, and one four to two bout."

It was like when Kacchan got kidnapped, outnumbered, and couldn't just charge into the room. What he did with Ochaka the first time wouldn't work as well as it might put the hostage in danger.

He ended up on the team of four, along with Mashirao, Ochako, and Tsuyu. So he was a villain this time, what's worse was that his quirk wasn't ideal for fighting indoors without destroying the building. Not that he'd want to, go all out against his classmates.

"Izuku!" Ochako bounced over to him, hands behind her back. "Isn't this great, we're on the same team again,"

"Yea!," why was she so close! Great he was going to start blushing again! "That's uhh great! We made a good team before."

"Ehh?" She muttered taking a step back from him. Her face was red, crud! Did he say something stupid? Think, this was easy Ochako was his friend, and the first girl that he ever texted. "Ye-yea! I guess we do, but this time we have two more so I'm sure we'll do great!"

"In addition the villians will be given fifteen minutes to prepare the building before the heroes show up. Victory for the heroes involves leaving the building with the hostage and both team members, victory for the villians is reaching the time limit or capturing both heroes." Aizawa continued. "Now, would the first group please step into the building."

That was his group.

The building was as bland on the inside as it was on the outside, with many empty rooms to hide in that weren't near the windows. The All Might pillow on the second floor in a room with two hallways and a staircase that lead into it. Multiple angles of attack.

"Should we split up Kiro?" Tsuyu asked, head tilting to the side.

Mashirao shook his head. "No, we have the numbers advantage, besides we don't know who we're up against, it could easily be a more combat oriented pair that could disable us if alone."

"Right," Izuku nodded, "But we still know who the hero groups were," Emi and Momo, Kacchan and Eijiro, Fumikage and Toru, Mezo and Mina. "I think that I should scout out who it is and then come back here, with my shoot style I should be able to make it back here before they can get me."

"So you'll be alone?" Ochako asked from behind her helmet. "Are you sure?"

He flexed, "Don't worry I'll be fine."

Probably at any rate.

He waited down below, At the end of the hallway that looked directly towards the front door, a staircase upward was but a few short steps away, and angled as such that he could kick up it easily using full cowl.

Ten minutes passed.

Then fifteen.

Then twenty.

At the thirty minute mark he finally peaked outside. There was no one out there, everybody else was in the observation room, so where were the heroes? They should be here! There was no rope or later on the front side of the building, and nobody outside of Toru was stealthy enough to slip past him. His teammates would have seen if anybody tried to go up the back side, so where on earth were they?

Twenty Five minutes.

Thirty.

The examine was half over and they hadn't even seen the enemy team. They had to be planning something.

"Knock, knock!" Shattered glass accompanied Emi's voice, followed by a shout, and several hisses from upstairs. Then came the laughter.

The building to the side! Dammit! Why didn't he think of that! He charged up stairs, only to see a thick pink cloud billowing down down the stairs like a fog bank drifting in from the ocean, swallowing everything up in it.

"Gas?" He gasped, covering his mouth as best he could, Heroes didn't use gas! It was a cheap trick! And maybe Emi had a point about making his mouth guard into a filter. In addition to the laughter, he the sound of fighting coming from upstairs. He could stay down here and guard the entrance, but that didn't mean they couldn't leave the way they came.

With a deep breath he charged through the smoke, pushing away as much of it as he could with his Full Cowl. It wouldn't be enough to breath, but it might stop some of the gas from getting into his lungs unintentionally.

"Hey, I'm over here!" A shadow popped up from the smoke once he reached the top floor. He punched it, but was greeted by nothing more than a balloon popping, releasing more that strang pink gas.

"Hey, I'm over here!" Another shadow.

"Hey, I'm over here!" Another shadow.

It was Emi's voice, somehow here and Momo had done a complete reversal on them, turning their own base against them.

"Hey, I'm over here!"

He made his way to the room where the Hostage was, and where his teammates were all laughing, barely able to stand on their own two feet.

"Izuku!" Mashirao giggled as he tried to force the words out. "It's, Hahah! The gas! Hagahah, it's laugh!" His tail went limp and his blond haired classmate fell to the ground clutching his sides.

Laughing gas?

"Hey, I'm over here!" Another shadow appeared. This one hit back, a well placed blow to the stomach that knocked the air out of him, followed by a hand on his shoulder, as Emi flipped over him with the grace of a circus actor. She winked at him, moments before a pie hit him in the face.

He tried to keep his breath, but he felt like laughing. Her quirk! "Gas? Was all he managed to ask before bursting out into laughter, whip cream still covering his face.

"You better enjoy that pie," She pushed him forward with a laugh. "I made it just for you Izuku!"

He fell to the ground barely able to control his laughter.

Emi kneeled down in front of him, poking him in the nose. "Oh, don't worry about the gas, it's mostly a harmless smoke dyed pink, with a bit of laughing gas that Momo made," She pulled down her own mask, and he felt a twinge of fear at the smile she wore. "A few normal breaths will barely make you want to chuckle. But when my quirk makes you laugh and you start breathing in gallons of the stuff."

She poked him again before standing up hands behind her back. "That's when I have you."

He had the weirdest crush on her right now.

AN: In a fair fight Emi would have lost. But she used the power of surprise and preparation to beat Izuku's group! Please don't think I made her stronger than she is, I just applied her quirk as best I could, I also put Momo on her team who was a big +. Anyways, next week/chapter is the Mei cameo half of you begged me for.
