Edit: I posted this chapter thinking it was finished, but it hit me several hours later that I had forgotten an important plot point. So I took it down until I had added what was left out.

Wow, I left you guys for a hot minute. Sorry about that. A bunch of stuff came up on top of my summer reads, and then I started school, so I've been busy. Thankfully, school isn't all that bad. Just right now it's a bit stressful since it's the holidays. But I'm glad to hear you all liked the last chapter! I worked really hard on it, so it was great to hear that it was good! Anyhow, I guess it's time to find out what'll happen to Takaoka now that All Might's here to deal with him.

Disclaimer: I do not own BNHA or Assassination Classroom.

The class stared with mouths agape, the man's exclamation still hanging in the air. The last hour had been crazy, and the vacation wasn't what they were expecting. But even Korosensei wouldn't have been able to predict this.

Suddenly, Takaoka's raspy laugh broke the silence as he picked himself up off the ground. "I was wondering when you'd show up, big guy," he called, lifting his face to show a crazed grin. He seemed oddly confident, almost like he expected him.

"I take it you're the madman who poisoned those children?" All Might said, ignoring his remark and staring him down.

"That's me," he admitted proudly without any hesitation.

"Where's the antidote? I'll take it by force if I have to," All Might warned with a faltered smile, sickened by how pleased he seemed to be with his work.

At the mention of the antidote, Takaoka's face cracked into a grin, and he began to snicker until he burst into another fit of laughter. "Um, sir," Nagisa spoke up, earning All Might's attention. He glanced toward the boy to see him holding up three vials full of a white-ish liquid. "This is all that's left."

"And not enough to save all of 'em!" Takoaka yelled, a maniacal laugh following. "I suspect about half of those kids'll die. Man, I wish I could be there to see the looks on their faces when they aren't picked!" he said with sick glee.

All Might's jaw tightened and his fist clenched. "I'll have you locked up in the most secure cell Tartarus has to offer," he said lowly before taking off and pulling his fist back. "Detroit-!"

Seeing the sudden movement, Takaoka called out, "Shigaraki, now!"

"Smash!" The hero threw his fist forward, only for it to go through a black misty portal that had appeared in front of his target and come out of the one directly behind Takaoka. There was a gasp of shock from everyone as All Might pulled his arm out just as the portal closed.

Another shadowy gateway appeared near Takaoka, and everyone watched in horror and shock as three figures emerged. The first was a man covered in what appeared to be severed hands, the second looked like shadowy mist in the vague shape of a man, and the last was a monstrous figure with a beak-like mouth and brains spilling out of its skull.

The giant figure let out a horrid screech as it swiped at All Might, who jumped backwards to avoid the attack and prevent it from going after the two boys behind him.

"No way!" Izuku gasped with a terrified expression. "Those villains are here too!?"

"Finally! I've been waiting to press continue on our game for an hour," Shigaraki said, throwing his arms out dramatically for emphasis.

"You two," All Might turned to look at them out of the corner of his eye. "I'll keep them busy. You get out of here and get that antidote to the rest of the class."

"But-" Izuku started but was cut off.

"Young Midoriya, there's no time to argue," he said urgently. "I've got these guys, and the class doesn't have much time."

The green-haired boy stared up at the man before his expression became determined. "Alright."

There was a screech as the monster rushed at All Might suddenly upon Tomura's command. Catching its fist, he barely kept his ground by digging in his heels, grunting with the effort. It brought up its other hand and went to grab his side only for All Might to grab hold of its wrist and keep it at bay.

"C'mon!" Nagisa urged, turning to run to the edge of the platform with Izuku following not far behind.

Before they could get close, a shadowy portal appeared in front of them, making them skid to a stop. Then more appeared around them, trapping them from all sides with no room between the gates to slip past. "Crap…" Midoriya cursed, realizing the situation they were in.

From the sidelines, the students looked on with many different emotions. Shock, horror, concern…

Karasma gritted his teeth as he surveyed everything. "Not good. These guys aren't normal, and they're with Takaoka… I need to get those two out of there…" Raising the gun up, he aimed at the moster and pulled the trigger.

The sound of a gunshot rang out and the bullet seemed to hit its target. The Nomue screeched as it was hit in the shoulder, but it didn't waver in its struggle against All Might.

Peering over the portals, Izuku watched with wide eyes as the wound on its shoulder closed up and left only a trail blood. "What…?" he breathed, believing his eyes had played a trick on him.

"Hey! This is a one on one match," Tomura complained as another shot was fired at the Nomu. "I thought heroes were supposed to play fair. Kurogiri, help me take him out." The shadowy servant complied, creating a portal in front of Shigaraki and another beside Karasuma's arms.

He reached in and his hand came out of the gate by Karasuma's arm. Reacting quickly, he jerked his arms back to avoid having them grabbed, but the villain's impressive speed allowed him to grab the shaft of the gun. Once all five fingers made contact, the gun turned grey and crumbled into dust.

The students and Karasuma stared down at the pile that used to be the gun with surprise and shock. "What the hell are these people…?" he muttered as it dawned on him just how dangerous this man was.

"Damn," All Might grunted, still struggling against the Nomu. Though he had been holding the creature back, he had been aware of the things happening behind him. "My students are trapped and their teacher is weaponless. Think! There has to be a way out of this!" Suddenly, an idea came to him.

His grip on the Nomu's hands increased, and he yanked the monster upwards and towards him harshly, taking it onto his shoulder with a yell from the immense effort. All Might turned quickly, and with a cry, he tossed the thing with all his might, sending it flying over the edge of the building. "It's me you want! So let's take this fight elsewhere!" With those words, he took off, jumping over the side where he had just thrown the Nomu.

"Quick! Follow Nomu," Tomura commanded urgently. Kurogiri did as he was told, making another warp gate that presumably led to the bottom of the resort.

"What?! The runts are defenseless, and you wanna just leave 'em?" Takaoka roared, gesturing towards Nagisa and Midoriya.

"They aren't our target. Nomu will need our help in crushing All Might. Besides, I want to watch when he's torn to pieces," Shigaraki let out a deranged chuckle at the thought.

"But-" Before the other man could argue, the villain stepped through a portal followed by Kurogiri and finally Takaoka, who looked rather bitter at the turn of events.

As soon as they had left, the portals that had trapped Midoriya and Nagisa also disappeared.

There was a silence that followed after the villains had left. There wasn't any cheering, just shocked looks at what had gone down. It wasn't long before Karasuma snapped out of it and climbed up to the helipad with the other students following behind.

"Are you two alright?" Isogai asked as he came up to them.

"Yeah," Nagisa answered quietly with a nod.

Midoriya remained silent, staring at the place where the Nomu had jumped off the side after his mentor. He didn't even realize another student had spoken to him until Isogai repeated his question. "Uh, yes, I'm alright," he said quickly, taking his hand and letting him lift him up. "We've got to contact some other pros to come back All Might up."

The others looked at him quizzically. "Midoriya, what do you mean by 'pros'?" Korosensei spoke up from Kayano's hands. "And would you care to explain how you performed such an impressive jump and sent an army-trained man rolling with a single punch?"

"I used my quirk," the green-haired boy answered, giving them a slightly confused look. Anyone could've come to that conclusion.

The group of students stared blankly at him, as if the information hadn't explained anything. "What's a Quirk?" Sugaya asked.

"And that guy, All Might, how'd he get up here? I didn't even see him!" Fuwa added with amazement.

Izuku blinked and remained silent as things began to click in his head. "If they don't know what Quirks and pro heroes are... is there a chance that villain could open warp gates into other dimensions? No, Quirks like that are rare, even more than a warping Quirk… But how else would they not know who All Might was or what Quirks are?"

"Um, guys," Meg interrupted, "as curious as I am, we've got more important things to worry about. We've got half a class of infected students and only three vials of antidote."

"We'll figure something out," Mr. Karasuma said as he clicked a button on his phone to end a call. "But first, let's get off of this roof. Wait here for the chopper. I'll go collect Smog."

"Ha! Please," a familiar voice called out. Everyone turned to see the three assassins from earlier standing in a group at the edge of the helipad, silhouetted by one of the bright lights. "The antidote won't do you any good," the one in the middle, Gastro, said sinisterly between the barrel of his gun as he rubbed the back of his sore neck. "Look at you brats. You really figured on getting out of this situation with your lives!"

"These guys again…" Midoriya muttered as he and the rest got ready for a fight.

"The man who hired you is gone. Let it go. You've no longer have a dog in this fight," Karasuma said in an attempt to persuade the three away from a fight. "I'm almost fully recovered from the gas. And these kids are strong, believe me. I suggest we be reasonable and stop this before anyone else gets hurt."

"Yeah, all right," Gastro gave in, removing his hand from his neck.

"I'll make you wish you hadn't-" Yoshida started hotly before he comprehended what had been said. "Wait, come again?"

"No worries," Gastro said, removing his gun from his mouth and shrugged. "You don't have to bother with us. Our contracts don't cover avenging our employer. Anyway, as I was saying, the antidote would only be useful to you if you'd actually been poisoned."

Terasaka lifted his head up from his spot on Yoshida's shoulder, humming with confusion at the assassin's statement. He sure felt poisoned.

"Well, technically you were, but not that bad," Smog clarified as he held up a canister. "You know that bug you can get eating oysters on the half-shell? I gave you a perfected version of that ol' warhorse. It ought to flush out of your systems in about 30 hours or so. Unpleasant but not fatal." Smog held up a vial in his other hand. "Now, this sucker is what our boss wanted us to use. If I actually had," he paused to let out a breathy laugh, "different story altogether."

"After we got the job, the three of us talked it over, hatched a plan," Grip continued. "The boss's idea seemed too harsh. We figured the handoff would play out just as well if you only thought you were in danger."

"And a bout of food poisoning certainly makes you feel like death warmed over, so win-win," the poison-expert finished.

"Since when does a hired killer have scruples?" Okano voiced everyone's thoughts. "Isn't going against your client bad for the bottom line?"

"Sweetheart, we take pride in what we do, but money isn't the be-all end-all. A client's needs are always considered carefully, and we do aim to please," Gastro explained. "But when we realized he never intended on giving you the antidote… It was either we try to live with ourselves after having offed a bunch of innocent junior high school kids, or we take out a hit on our reputation. Seemed like a fairly straightforward, ethical decision to us. And there's always a way to bounce back if you're clever."

"So, guess this job was a wash," Smog announced, "but at least none of you are going to die because we don't have scruples." He tossed the canister from earlier to Nagisa. "Here, give that supplement to your buddies. And make sure they get plenty of rest. They'll probably wind up feeling better than they did before this all started."

It wasn't long before the helicopters Karasuma had called in arrived and began to lower themselves to the helipad. "Thank you, gentlemen," Karasuma spoke loudly to be heard over the blades. "But I'll believe it after I've seen those kids make a full recovery. In the meantime, I'm afraid it's protocol to detain you for questioning."

"Uh, yeah, okay," Gastro agreed slowly despite how reluctant he and his companions looked. "If you wouldn't mind making it quick so we can move on to the next job, that'd be great."

The group of assassins made their way towards one of the landed helicopter's, but before Grip could get close, he was stopped by the troublesome redhead. "You disappoint me," he remarked in a snarky tone. "I thought you'd at least want a grudge match between the two of us. You're a samurai. Isn't your honor threatened by hot sauce?" he taunted, a devilish smile on his face as he held up several tubes of spicy condiments.

The assassin didn't seem fazed at all by Karma's taunts, instead maybe just slightly annoyed. "Part of the samurai code is not to kill people out of spite," he informed the boy before patting him on the head, erasing his proud smirk. "I'm content to wait for the day someone puts a price on your head, Hun. Because it'll happen. Guarantee it."

"Let this be a lesson to you," Gastro joined in from the helicopter. "You wanna rematch? Make it to the big-time." The blades spun faster as it began to lift off, creating a strong wind. "Become a worthy target! Then we'll come back and give you the assassination grand tour!" To add some extra flair to his speech, Gastro let some of his ammo fall from his pockets as he and the other two were taken away.

While the other students around him were spellbound by the speech, Izuku was too busy with his thoughts to care much. He remained silent as they boarded the helicopter, just aware enough to get into the back and seat himself in between Kayano and Fuwa.

As he felt the chopper lift off and begin to rise, Isogai spoke up, "So, now that we've got the real antidote, I think we need some questions answered, Midoriya."

"Yeah. Lke, who was that really buff guy?" Yoshida chipped in, having not heard the man's name spoken in the chaos.

"What about those guys who saved Takaoka's skin? They make those assassins we ran into seem normal," Meg pointed out.

"What about that monster they had?" Isogai reminded. After all the sudden questions that were hurled his way, the green-haired boy looked at a loss for what to say from how overwhelmed he was.

"Okay, children, one question at a time," Korosensei spoke up, stopping anyone else from speaking up. "You mentioned you used your… uh, Quirk to perform those impressive feats earlier, correct?" Izuku nodded his head. "Then why don't you start there and explain to us what Quirks are."

"A Quirk is an uncanny ability that someone has. Where I'm from, roughly eighty percent of the population is born with one," he explained, earning him some odd looks from a few who caught his odd wording.

"What do you mean 'where you're from'?" Karasuma asked as he stepped into the holding area, a new gun now in hand. When he called the helicopters in, he told them to bring him another weapon. It wasn't anything special, just a standard pistol in case they ended up running into the villains again.

"I've got a theory. I think that mist villain's Quirk can open warp gates into other dimensions," he said slowly, already expecting the worst. When the room didn't instantly erupt into laughter, he continued, "You guys didn't know about Quirks or pro heroes. And the more I thought about it, I realized I hadn't seen any Quirks all night. The only thing I can think of is that the villain's warp gate opened into another world, one without Quirks and heroes."

"And I think your theory is correct, Midoriya," Korosensei said, surprising the boy. "Unless eighty percent of the population is hiding some super ability, I don't think we're in the same world as the one you or those villains are from." There was a certain irony in that an indestructible ball was saying that.

"I'm going to take a wild guess and say pro heroes are people who use their Quirks to fight villains," Nagisa added from beside Izuku.

Midoriya nodded again. "Yeah. Heroes have a license to use their Quirks. For everyone else, Quirk use is prohibited."

"Sounds like you're a felon to me," Karma commented with a smirk.

"N-no!" the other boy defended with a stutter. "There's a clause that allows Quirk use for self defense! Many people accidentally activate their Quirks in high stress situations!"

"Speaking of bad guys, what about those guys from earlier?" Fuwa broke in, anxious for more answers. She felt like she was in one of her favorite detective mangas except with a super twist.

Midoriya's brow furrowed. "I'm not familiar with them. Warping Quirks are rare, so I'm sure if I heard about a villain with one, I'd remember. And I've never seen anything like hand guy's Quirk," he answered, beginning to slip into his muttering.

Seeing that the boy was slipping into what the teacher assumed to be a habit, Korosensei spoke before he was too far gone, "I have one final question regarding the villains: What was that beast they brought with them?"

Izuku noticeably paled a bit and stopped dead in his muttering. "I'm… not sure," he answered honestly. "I don't think it's human… When Mr. Karasuma shot it earlier, it regenerated. That hand guy already said it has a shock-absorption Quirk, so it must have two. I've never heard of anyone being naturally born with two Quirks, and experiments to give someone two Quirks have been outlawed for being too dangerous."

"Any information on the man who came to your rescue?" Karasuma asked from his place near the entrance. He had heard the name All Might, but that was about it.

After his mood had soured so much, none of them expected him to brighten so quickly and suddenly. "He's the greatest hero in Japan, All Might!"

"But if he's the best…" Terasaka started hoarsely.

"...and that monster was able to take him on like that..." Yoshida continued. It dawned on everyone else what they were getting at.

"...then these people are not to be taken lightly," Korosensei finished for them. "In the incident that we run into them again, you children stay away. It's far too dangerous for any of you to try your luck with them. Hopefully, they'll hold off on showing up for another twenty-three hours."

"Not likely, but we'll do everything we can to protect the kids. Their safety is priority," Karasuma shook his head, already thinking of plans for if they appeared again. It was a small island after all, and there was no way All Might could hold them off forever.

Well, that's it for this one. I hope this one was just as enjoyable! I was going to make it longer, but I had left you guys without an update for so long that I figured cutting this one a little shorter than intended wouldn't hurt since I can just include it in the next chapter. Hope you enjoyed!
