"Detective! We have signs of disturbance in the facility, shall we infiltrate?", a police officer asked his superior for orders, the force were asked to remain outside the parking lot and move on command.

"Not yet, we move when Nighteye comes out!"

"What the Fu-! Gas!? Sir! some green gas has just appeared from the lower levels!"

Tsukauchi grabbed his hat and coat to move onto the field.

'Hang in there Mirai-san!'

There was utter chaos, fighters going wild, their quirks flaring out of their control and from what Nighteye could see, several of them losing their individualities.

'The drug is seeping in from the air vents, the doors are sealed, this has turned into an instant gas chamber', Out of the corner of his eye he noticed that the staff members were putting their masks on. 'So this whole event was pre-planned!'

He relentlessly gave in and addressed the annoyingly loud Rabbit-girl, "Tiger Bunny, you are the quickest one of us, see those people at the back?", he whispered while pointing at the small hallway. "The staff members have gas masks, since we are not affected yet, might as well keep it that way. I want you to-"

Before he could finish his sentence Rumi had hopped off to the above-mentioned area, he sighed, 'These rebellious teenagers really get under my skin',

but he was satisfied that the girl got the job done.

"Here ya go and you would probably need this", she yelled while passing around the stolen masks and gave Nighteye a gun!? "I stole it while I was at it, I know your quirk thanks to this nerd, since you probably have used it today, you'll need a weapon."

"Haha, thanks Tiger Bunny, now let's go over the plan one more time, Wolf Unicorn, do you still have your quirk?"

Izuku gave him a perplexed look as he moved closer to the Rabbit-girl, he noticed there was a cut on her forearm, "M-May I?"

"You seriously think this is a time to be a fucking genttleman!? Go ahead!"

"O-Okay", complying with the girl's demands, he touched the cut and activated his quirk, his horn flared up with golden energy pouring off from it.

Nighteye and Rappa watched in slight satisfaction and awe as the cut on TigerBunny's arm vanished in an instant.

"Yeah, but what do you mean? How can I 'lose' my quirk?"

Nighteye hummed as he tried to comprehend Izuku's quirk "It's great we have a healing quirk down here, we might need it… Now here's the plan, Rapper and Tiger Bunny are our front line of defence, I have limited shots on this thing, so we'll only use it if we have to. I have my seals for mid-range attacks and here take this Wolf Unicorn", Nighteye explained as he passed on his knife to the uni-hornette. "The doors to the passages and emergency exits are locked, our only option is through the driveway, from what I could gather they'd only have some low-key guards there."

"What do ya need our help for?", the mindless puncher questioned while crossing his arms.

"There's something I'm concerned about, I want you two to bulldoze through and make us a path, Wolf Unicorn you'll be with me, since your quirk isn't offensive."

Izuku was about to explain that his quirk is offensive enough, but he remembered what Dr. Oguro told him, if he used his quirk on someone, there was no way he could reverse it… yet?

"These people are non-consensually dosed, so go easy on them."

Rappa and Rumi formed a shit-eating grin while they shouted in unison, "Yeah sure!"

With a last minute explanation of the backup plan, the front line team charged in the crowd with their preferred appendages in full power.

Nighteye and Izuku were slowly following the two with their weapons intact, the latter had little to no experience with knives, so he was running in blind.

Mirai noticed that the purple mist was following them as they went and in a moment of panic, the fog materialized itself just behind the greenette, paying caution to the wind, he shot off his seal to the hand that was intended to get a hold on Izuku.

'So, this is a Warp-quirk, figured the big bad wouldn't show up and reside to cheap tricks to have his way, maybe All Might did damage him enough and he needs Wolf's healing quirk? Not that I ever believed he would die…', He analyzed that the mist must have some sort of surveillance over them. 'Wait, surveillance!', without a second thought, Mirai shot three bullets to the overhead cameras, shattering them, effectively making their enemy blind.

In a building that was still, far far away

"This is unfortunate, our eyes on the scene are tampered with. Not only we won't be able to take specific quirks, they might have a chance to make it out… alive."

The dark lord thought out loud as he leaned back in his chair, hooked up to multiple medical equipment was still a chore to say the least, the inconvenience it brought, the pain, at first the man thought he could swap a couple of quirks with Gigantomachia for such an affair, but that would put a damper on his ace of spades.

The butler themed, mist-man stood idly by as he continued to try and catch the Uni-horned boy.

"He will make sure the latter doesn't come to pass, master."

Rumi noticed as they were just a few meters away from the exit, that the guards brought a certain hooded figure to the facility, the guy was dressed in a hoodie and track pants, and had the stance of a martial artist.

Rappa, who had punched his way through the gates, approached the hooded figure with pure delight, "Up for a fight Eh!? My kind of guy!"

Somewhere, a greenette 'accidentally' punched someone a bit too hard.

He blasted the fury of punches on the hooded-figure "Let's see what you got!"

Usagiyama watched as the unknown fighter gracefully evaded his punches and swiveled his arms? As he cocked a straight hit in Rappa's face, the punch had such power that it threw someone as bulk as him a few metres away.

The Rabbit-girl, in an attempt to help a fellow fighter out, hopped-high from her former position and attempted to land a near-fatal drop kick on the guy, but just as her leg was about to hit Hood's face, yes she dubbed him, the creature tilted his head back, instantly evading her attack, while simultaneously bulging? His legs and kicked the girl in the gut.

She went flying through the crowd while groaning in pain from her opponent's attack, fortunately she landed in the hands of our dear Uni-hornette.

"A-Are you o-okay?!", Izuku descended into a blushing and stuttering mess as he helped her on her feet,

"I TOLD YOU I CAN HANDLE IT!"

"O-Okay!"

Nighteye watched in horror as Hood's hand stretched like a grape-vine and was about to reach them with full power, he took out two of his special explosive seals and shot them off at the creature's shoulers, sending him flying through the basement.

In Mirai's attack the creature had lost his arm, he stood up, regenerated? And spoke in an eerily intimidating voice, "Y-You are S-Sir N-Nighteye…"

With that comment Hood mindlessly started his extendo-armed punches towards the group and his whole surroundings.

Horrified from the sudden attacks, the widespread panic worsened among the crowd, people began running towards the closed doors, even the guards who were protecting the only exit filed out and quite possibly locked the metal doors from outside.

Nighteye effectively dodged each of his punches, the figure's assaults were robust, but predictable. He also observed that thing was targeting him specifically, so he leaped away and distanced himself from his comrades.

"Ya okay High-class!?", the unbelievably annoying rabbit teenager perked up.

"Yes, you three execute plan B."

Within the piece of architecture that was O-so, far far away,

"Ugh, how pitiful, the sponsor's can't even watch the match!?"

The supposedly-free willed bartender who still had to take care of a man-child after this ordeal, spoke up, "Due to Nighteye's deduction, our view is limited."

"Ah, I wish I could sit in the front-row seats of this clash."

"I wouldn't advise that, not specially after considering the fragile shape you are in, not to mention you intend to involve him, even though he is tired today, it's not wise to engage him unprepared."

The dark lord was visibly agitated by his butler's comment "It's always him, the itch of my back, my own personal bugbear..." his persona came back to normal as he diverted his attention to the other occupants of the facility. "I'll just settle for three or four misssing reports for now."

Nighteye focused in on the enemy as he prepared his seals and got ready to attack, he was only left with one explosive and other regular high density seals, 'The dark-bluish skin tells me it's an mutant type, but with my knowledge such a quirk should be emitter, as he couldn't hold that extended form forever, he need to take breaks between hits, that's why he tries to create chaos to divert attention to that fact, he can transform libs at their very core structure to make them stretch in the way they did, he can also bulge, quite effectively using it as a 'Muscle Augmentation' power, it also allows him to heal, though I do wonder if he is involved, their is a possibility of multiple quirks.' he analyzed while charging in towards the enemy.

'His fighting style isn't well incorporated with the quirk, bulking up takes time and shifts his centre of gravity, it's attacking style is mediocre at best but the discrepancies get corrected by that wild quirk, thanks to his incompetence, I can exploit these loopholes to make an opening!', Mirai thought up as he ducked under the creature's attack and fired off the last explosive seal, the piece of weaponry hit Hood in the gut where it exploded on impact, resulting in leaving the figure with two halves, the burnt and dead tissue of lower body and the relatively fine upper part.

The creature screeched in pain as it's remaining body tried to regenerate, Mirai knew this was probably against human rights, but this was his only shot to get his message out.

While Hood was preoccupied, Rumi hopped off for the exit, she was sprinting in full speed when she sensed something creeping her way, out of the corner of her eye she looked in horror as the creature shot off his extended left arm in an attempt to capture the fleeing teen.

Izuku was about to ask Rappa to throw him at the arm so he could revert it, but instead, the man shot off from his position and blasted a fury of punches at the bloody pulp of their enemy.

Just as Nighteye presumed that everything was going according to plan, alas in a moment of panic, Hood went wild with his regeneration and attacks. He kept Rappa engaged by forming a plain shield of muscle fibres from his right arm and sharpened the barely formed left leg which was meant to hit Izuku, but the hero intercepted, resulting in chopping off Mirai's right arm from his shoulder, he shouted in pain as he fell to the ground.

"Sir!" Izuku exclaimed as he caught the wounded hero, he took notice that Rapper had hood fully engaged and that Rumi was out of the facility, so he flared up his quirk and touched Mirai's bloody stump.

Nighteye was on the verge of losing consciousness from the pain when the said sensation vanished in a second, he opened his eyes to find out that he was alive and well, the arm was back and as healthy as ever, even the scratch marks from before were gone, for a moment he thought this was one of his freaky dreams, but he noticed the worried expression of Wolf Unicorn and it all hit him. 'He is the Healer…!'

"T-Thank you Wolf, I don't think I have come across such a fast healing quirk before, it doesn't seem to have utilized my stamina, you look the same as ever..." ,He was about to get deeper into the teen's quirk but he saw that Rapper was now struggling with the figure which had done regenerating.

"Let's talk about it later."

Some moments earlier

"Back-up plan?", Rappa raised his question to the leading hero.

Nighteye had just explained the two about the police force who were set outside the underground facility, at first the fighter as well as the school girl looked a little uncomfortable at the mention of the law-enforcers, but for different reasons.

"What do you want us to do, get the word out!?", Rumi chimed in while adjusting her gask mask.

"No, the plan was for them to infiltrate once I was out of the facility, this plan is incase if we encounter some low-life who's giving us trouble, summoning heroes with ideal quirks would be time consuming and irrational, here we'd have to play our ultimate card."

'What's that...?", Izuku asked the hero while rubbing his chin with the bloodied pen, 'BLOODIED PEN! GROSS!', he internally panicked while throwing away the piece of stationary.

"I'd give you one hint… All Might"

The other two deadpanned at the desperate attempt at humor while Izuku's eyes basically glowed with sunshine and stars.

"YES!", he screamed at the top of his lungs, the greenette gathered his composure when he saw the weird looks being thrown his way,"I mean, I wish the situation wouldn't get to that..."

Nighteye sighed, as much as he wanted the man to rest after his big mission, he knew if someone was in in trouble the Symbol of Peace will fight through thick and thin to save them and today after what he'd seen from the glimpses of Rapper's future, they'd need him.

"Where is the damn fight club!?"

"I am not sure Baku-bae, maybe this way!"

"What! I thought you knew where Bugs-Bunny goes to fight!"

"Well, there is not a fixed place for her, she crashes any fight club near her."

"What the Fu-"

Katsuki and Camie were searching their way to find Izuku and Rumi, while Katsuki was overly anxious about his friend and the situation he might be in, Camie was awfully calm about the whole ordeal, it was like she had experienced this before… multiple times.

"Why'd she run off like that, she thought we were too weak for the club!?"

Camie slightly chuckled, she wanted to spill the beans as to why Rumi was overly attracted to Izuku right off the bat but she resisted for now, "You were stuffing yourself with Takoyaki Baku-bae and I was paying for the second plate!"

Katsuki just 'Tched', truly it was one of the best he'd ever eaten and he'd be crashing the stall multiple times in the future but he was worried sick about the resident greenette, ever since he had joined that stupid quirk counseling, the nerd refuses to use his quirk on another human being, it literally took him hammering his own hand to have him use his quirk on Katsuki. 'Which is pretty fucking dumb, now that I think about it and it hurt like a bitch!'

Camie's calm and Katsuki's shit lost when they saw a large crowd of police force ready to dispatch outside the allegedly underground fight club.

Both teens asked a couple of officers who just assured them that there was a hero present at the scene and that they had the situation under control.

It took a lot of yelling and some warnings from the police officers for Katsuki to stay put and not barge in head first to get the damn nerd out of this crap.

A few moments later they watched in awe as their Rabbit-eared friend shot off from the facility into the sky following with the green gas, it was a pretty heroic sight and looked like a familiar scene that dealt with certain giant beings.

Tsukauchi instantly recognized the said trouble-maker and sighed, 'I don't want to deal with this today.'

"Someone just bursted out!/ A kid…!?/ Looks like a highschooler to me./ Is she on our side or is she fleeing?", random perplexed looks and questions came from the crowd as they gawked at the still gliding Rabbit-girl.

"Call the Numero Uno! We need ALL MIGHT!", she exclaimed while landing on a nearby building.

Katsuki and Camie were about to storm through the building to get to Rumi, but before they could even take a step, she jumped back into the facility.

'If something happens to Deku, she'll be dead!'
