(A/N: The above picture was drawn by me! I absolutely love art and all things related. I just wanted to share it here. What do you guys think of it?)

"Ready Mei-chan?"

"You bet I am!"

"Problem Child... NOO-"

Shouta had no idea as to exactly when and how he had ended up as a guinea pig for whatever his problem trio liked to term as "Experimenting" but he sure as hell didn't enjoy it. Especially since either Nemuri or Majima always found a way to sneak some pictures and post them into the group chat. He did NOT like being laughed at.

Right now, the poor sleep-deprived hero was being flung into the air while Mei, Majima's devil-spawn, aimed what looked like a lazer at him.

"Fly still Mr. Scruffy! I gotta aim"

Izuku stared at the flying hero with wide eyes practically shimmering with unbridled excitement.

Shinsou, standing right next to his green haired brother-figure, maintained his 'I'm-too-tired-for-this' exterior but inside, he was far too excited to see how Mei's new gun worked.

Shouta never regretted teaching his purple haired carbon-copy how to use his scarf as much as he did now. Yeeted into space by his very own scarf... Traitors.

A blue-ish ray flew towards him and even before he could blink, he was encased in a floating pewter-hued gooey ball... In mid-air.

"YESSSS! I'VE DONE IT!!" The pink-haired demon yelled in triumph. "MY NEW BABY IS READYY"

"WOAHHH MEI-CHAN! THAT'S AWESOME!"

"How are we gonna get him down now?"

Izuku paused mid-celebration and looked at a slightly worried Shinsou. He turned to look at Mei who was scribbling some crazy codes onto a piece of paper.

"Mei-chan?"

"Hmm?"

".....?"

"Oh, I dunno"

"WHA-" Izuku and Shinsou sweat-dropped while said inventor stood oblivious to the piercing glare directed at her from the sky.

Izuku shook his head and looked at his floating mentor. "Hang in there, Aizawa-san! We'll figure something out"

"Well, thank you, problem child. I was really planning to get some coffee from across the street"

"Well don't. You can do that after we- oh" he was kinda late at realising the sarcasm.

If he could, Aizawa would have face-palmed himself hard enough to knock himself out. Since he couldn't, he chose to groan out loud instead.

"Mei-chan, do you know how to get him down?"

"I told you, I don't!" Mei exclaimed in slight irritation, "but we can try to develop an anti-anti-gravity-freeze-ray!"

"An anti-anti-what?" Shinsou and Izuku asked at once, horrified by the mere prospect of hearing more about whatever that was.

Izuku started sweating and eyed Mei warily. "Uh... Mei-chan? What exactly is this gun made for?"

Her unique yellow eyes sparkled as her hair blew with the sudden wind and Shinsou badly wanted to smack her. 'Now's not the time, Mei'

"I thought you would never ask! This is my new Anti-gravity-freeze-ray! I thought I'd come up something innovative to catch villains who can fly. You know, especially after the whole 'flying-Nomu' thingy. I basically combined anti-gravity with-"

"Problem children-"

"-Some movement-arresting substance that also suppresses your quirk, of course anti-gravity can't be suppressed as it's incorporated into it, and-"

"Izuku-"

"-is easy to spread around like a lotion or gum, you know, to make it more effective-"

"IZUKU! SHINSOU-"

"And to make it portable and oh, he's floating away"

Izuku and Shinsou were shaken out of their stupor and looked at there Mei pointed to.

"OH MY GOD HE'S FLOATING AWAY!"

Izuku was quick to jump onto the nearest tree and onto the rooftops in order to chase the flying ball before realising, quite lately, that he had absolutely nothing on him to help him catch the disfigured Aizawa-balloon.

"GODDAMNIT! TOSH-"

"ON IT!" Shinsou, who was hot on Izuku's trail, yelled as he shot the scarf at Aizawa. The cloth grazed the goo but didn't stick to it as the gel repelled quirk or quirk-enhanced objects.

"CRAP! WHAT NOW?"

"MEIII-CHAN!!!"

"I am TRYING!" The not-so-genius snapped, chasing the floating man with the all-terrain shoes she was so proud of. "I can't just- UGH! I CAN'T UNDO IT!"

"WELL NOW WHAT?!? WE CAN'T EXACTLY LET HIM FLY AWAY!" Izuku yelled, trying to catch up with Mei.

"QUIRK-SUPPRESSING MY FOOT! NOW THIS SCARF IS BASICALLY USELESS" Shinsou added, panting slightly.

"WILL YOU THREE STOP BICKERING AND DO SOMETHING?!!"

"SORRY SENSEI!"

"Ohoho this is fun"

"GAHHHHHH" Both Izuku and Shinsou almost lost their balance and plummeted straight into the trash cans below. Almost.

Izuku was the first to regain his composure and attempted to glare at the Chimera peeking out of Shinsou's scarf. "Nezu-san!? How in the world are- when did you-"

"I DIDN'T EVEN FEEL YOU GETTING INTO THE SCARF!!"

"Shinsou-kun, please do not yell. I am right on your back. I was there from the beginning. Aizawa-kun being a test subject was too much fun to risk missing out"

"You mean to tell me that you were there all along and you DIDN'T TELL US THAT AIZAWA-SAN WAS FLOATING AWAY?!"

"Toshi, calm down!" Izuku tried to calm the other down but he was seething as well. "Nezu-san, we're gonna talk about this later. For now, please help us-"

"CAN YOU GUYS SHUT UP AND HELP ME?!" Mei yelled at them from a little ways away. Izuku and Shinsou gulped and sped up to catch up with Mei.

Aizawa closed his eyes with a deadpan expression and was most certainly thinking something along the lines of 'I'm gonna get a lifetime of coffee and then kill them all'

"Have you tried catching him with the scarf?"

"WELL WHAT DO YOU THINK, GENIUS!? YOU WERE HERE ALL LONG!" Izuku burst out while running.

"Have you tried flinging yourself into the air using the scarf?"

"WHAT DO YOU THINK WE'VE- oh wait, we didn't! TOSHI LAUNCH ME!!"

Nezu pulled out a small portable flask and started sipping his tea while Shinsou used part of his scarf to wrap around Izuku's waist and shot him after Aizawa. Luckily, Izuku caught on to the goo.

"YESS- WHA-?!!!" Shinsou let out a strangled gasp as his scarf started to go limp and Izuku started to lose his grip on the gooey substance. "MEI-"

"LET GO OF THE SCARF, DUMBASS! THE QUIRK SUPPRESSANTS FOLLOW INDUCTION! IT'S REPELLING THE QUIRK ENERGY FLOWING THROUGH IZU-AGH! LET GO!!"

Shinsou, too lost in the information dumped onto him, released the scarf that caused Izuku to get his hands stuck in the goo. "GODDAMNIT TOSHI!"

"HEY IT'S NOT MY FAULT!!"

"STOP WHINING! YOU PROBLEM CHILDREN ARE IN A HEAP OF TROUBLE!"

"I'M SORRY AIZAWA-SAN!!"

"HOLY SHIT! WHAT THE HECK IS GOING ON?!"

"HAWKS-SAN!!!!"

Hawks, who was patrolling the area, accidentally stumbled upon the most amusing scene he had ever seen. Who would've thought that the ever-grumpy Eraserhead would be floating away in a strange chewed-out gum? Not to mention that there was a green vegetable, and not coffee, floating with him.

"Do you need help?"

"WELL NOT REALLY! WE'RE JUST GLIDING- YES WE NEED HELP, DUMBASS!" Aizawa snapped, having lost his last reserves of patience.

"Ok? Gee, no need to yell" the winged hero was about to reach out to catch them but Mei yelled at him to not to.

"THE SUBSTANCE IS QUIRK-REPELLING AND QUIRK-SUPPRESSING! YOU'LL FALL TO YOUR DEATH!"

"THEN WHAT AM I SUPPOSED TO DO, MISS??"

"GET A ROPE! SOMETHING THAT CAN ACT AS AN INSULATOR!"

Hawks groaned and rushed to find "something that can act as an insulator". He dived in and caught a bedsheet that was set in someone's backyard to dry.

"WOULD CLOTH WORK?!"

"YES! QUICK! TIE IT AROUND IZUKU'S LEG"

Hawks wasted no time in complying and tied the bedsheet to Izuku's leg. "NOW WHAT?!"

"DRAG THEM BACK TO UA"

"That's a wise choice"

Mei was about to call Nezu a rat but stopped herself from doing so be focusing on the duo being dragged instead. Once they were back to the UA training grounds, Hawks was asked to keep floating till they came up with a solution, much to the chagrin of the winged hero.

"Argh!! This is a totally unexpected outcome and I have absolutely no idea what to do!!" Mei whined, scratching her hair in a very concerning manner.

Nezu, who was enjoying the show, decided that it was enough and that he didn't need a grumbling cat being a thousand times grumpier and demanding twice the pay and thrice the coffee in his office. "How did you get the substance to become gravity-resistant, Hatsume-san?"

"Huh? Oh.. I asked Uraraka from 1A to help me with it. Why?"

Nezu shrugged and continued sipping his tea. Shinsou sighed and shook his head. He had no idea where Nezu always pulled out his tea cups from nor did he know how his friend, a genius inventor, was so dumb.

"Mei.. get Uraraka-san"

"Okay? I don't see why though"

Shinsou slapped his face harshly and that made Mei realise what they meant. She gaped at them before cursing under her breath and literally sprinted to get Uraraka.

"Mei-chan, why did you drag me all the way here?! We were watching a mov- AIZAWA-SENSEI?! IZUKU-KUN?!"

"Ah, Uraraka-san. I guess now you know why you were dragged here" Nezu spoke up, a mischievous glint in his eyes.

Uraraka gaped at the scene before her and shook her head. "Mei-chan, this is crazy! You don't know how to undo this and yet you proceeded to use it! That's dangerous!"

"URARAKA-SAN! GET US DOWN BEFORE YOU TURN INTO IIDA-KUN!"

Uraraka face-palmed and made the release symbol, making the duo almost stall into the ground. Luckily, Hawks caught them before they hit the ground.

"You children" Aizawa growled, peeling the goo off himself rather harshly, "are grounded! No more experiments! No more training! No more coffee!"

Izuku and Shinsou gasped at the last statement while Mei had a heart attack when Aizawa said no-experiments.

"And Uraraka!"

"Y-yes Sensei!"

"Lips sealed or no mochi and no TV"

Uraraka nodded quickly and made a zipper motion towards her lips, "Yes Sensei"

"Good. As for you, Nezu. Double pay and triple the coffee in my office"

Nezu cackled and climbed onto the already grumpy man's shoulders. "You're becoming predictable, Aizawa-kun. You and I both know that your request can't be fulfilled"

Aizawa grumbled and let out a string of colourful words which the kids didn't mind, especially since they caused him so much trouble.

Izuku and Shinsou went paler than ghosts when they found a picture of Aizawa floating posted in the gc and Midnight laughing at it for hours, losing 90% of her lung capacity. Aizawa had grounded them for a week more.

The poor kids decided that their poor sensei was too tired and old to be their test subject and officially relieved him of his duties as a guinea pig. And if Aizawa ever saw Nemuri hanging upside down while encased in tape and paint or Mic's hair wrapped around the man, dyed pink, he was sure to click pictures and post them in the GC himself.
