The very next day, Aizawa made an announcement.

"We're bringing in a group of particular individuals who have experience with Hero Work study. They'll be explaining the full details of how things will go."

The door opened, and Izuku perked up when he saw Mirio come in with twelve other people, a girl with long, cerulean hair, a tired-looking guy with spiky black hair and slightly elongated ears, a young man with curly black hair and glasses who looked nearly identical to Ben, a boy with dyed short blonde hair, a small anthropomorphic tuxedo cat with bright blue eyes, a beautiful girl with platinum blonde hair, a tall, artistic looking boy with blue hair, a girl with short dark brown hair and red eyes, a younger girl with long orange hair and glasses, a girl with fluffy brown hair, a handsome young man with brown hair, and an elegant girl with red hair in a ponytail.

"Three of these students belong in Hero Course Class 3-A and rank at the very top of our student body, hence why they are called the Big Three." Aizawa said, "As for the other ten, they are students in Hero Course Class 3-B and are all aiming to be Underground Pro Heroes. As such, they are called...The Phantom Thieves."

"Wait..." Tsuyu's eyes widened in surprise, recognizing the girl with orange hair. "Alibaba is that you?!"

"Tsu? Oh my gosh, it is! I know that voice!"

The rest of Class 1-A was shocked to find out that the legendary Big Three and Phantom Thieves were in their classroom. They'd heard about them, of course, and knew about their reputation. They were said to be so skilled despite being in high school they were practically already Pro Hero level. Mirio Togata, Nejire Hado, and Tamaki Amajiki composed the Big Three while Akira Kurusu, Ryuji Sakamoto, Morgana Kurusu, Ann Takamaki, Yusuke Kitagawa, Makoto Nijima, Futaba Sakura, Haru Okumura, Goro Akechi, and Sumire UYoshizawa made up the Phantom Thieves.

"Hey, isn't that the Pants-Fall-Off Guy?" Kirby asked as she pointed at Mirio.

The students, save for Mirio, all face-faulted, while Aizawa surprised everybody by actually doubling over in hysterics.

"Really, babe?" Katsuki sighed, shaking his head.

"What?"

Mirio just chuckled. "Yeah, she's talking about my performance at last year's Sports Festival. Back then I was complete garbage with my Quirk, so I wound up dropping my pants during the first event."

"Man, that sure got a blush from Takamaki, though!" Ryuji smirked only for Ann to punch his shoulder, which he laughed off.

"Gotta admit, that's the first time I've laughed in forever." Aizawa sighed as he recomposed himself. "Anyway, let's get some brief introductions out of the way. Amajiki, you first."

Tamaki was staring with such intensity that it felt like he was glaring at the class. Even Izuku, Katsuki, Shoto, and Ben were stunned. Though in reality, Tamaki was just trying to muster up the courage to speak by imagining everyone with potato heads.

"It's no good... My anxiety's acting up too much. You guys go first. I can still see their bodies so I still identify them as people..."

"Is this guy really one of the top heroes here?" Oujiro wondered.

The cerulean-haired girl laughed. "Well, this is our human-sized kitten Tamaki Amajiki, and I'm Nejire Hado. Anyway, I'm sure you first-years have been excited about work study, and let me tell you all that excitement is justified."

Suddenly, she got distracted by Shouji's face mask, Mina's horns, and then by all the little physical quirks of some of the other students.

"Oh my gosh, there's so much I wanna know about each and every one of you! Let's have a Q&A."

"Down, girl!" Makoto said, grabbing Nejire by the ear and pulling her back.

"I don't know whether to be envious of the guy she might be dating... or pity them for her overly bubbly personality," Sero said.

"Hehehehe, she talked about my balls," Minoru smirked, tapping his hairballs as they wobbled. "That's sexual harassment if I ever saw it!"

"Honestly, Mineta..." Momo groaned, shaking her head.

Mirio cleared his throat. "Anyway, the name is Mirio Togata and along with my fellow Third Years, I'm here to explain the volunteer course work study. Now I was told you each got your provisional license already. That's impressive work for first-year students.

"It makes me wonder, though... Aizawa-Sensei, who would you say are the top three students in this class overall?" Haru asked politely.

"Taking into account both academic skill, physical aptitude, and Quirk capability... I'd say my top three students are Midoriya, Bakugo, and Todoroki. But then again, we also have Ben, Penny, Kirby, and Hilda to take into account."

"Oh hey! Ben!" Futaba grinned. "The Ward of UA after that incident with All For One!"

"Don't remind me..." Ben muttered.

"Well, if what Aizawa-Sensei is saying is true...Then I wanna fight the whole class!" Mirio beamed.

Everyone headed for Gym Gamma, where they saw Mirio doing some stretches. Already Izuku was muttering to himself.

"Deku, what the fuck, you haven't even seen his Quirk yet," Katsuki noted.

"Actually, I did. A few days ago, Mirio-Senpai came to greet me as I was taking out the dorm's trash. He was somehow able to phase through a solid wall."

"Honestly, Mirio, not everyone has your drive." Yusuke sighed. "We could have just explained how the work-study improved us."

"If you're not careful, some of these guys could spend the next few years in a hospital bed," Morgana noted.

"Try to hold back a little," Sumire added.

"Don't go counting us out just yet. We've fought against Pros before and won." Fumikage said.

"Given you're the tops in this school, you might be able to take on most of us," Minoru admitted, "But it was a mistake to take on the entire class at once. You were better off just taking on our top hitters as you implied. That would still get the message across."

Mirio smirked playfully. "Well, if you think he's so strong, maybe you want to take the first shot."

The class quickly rushed Mirio down, only to get completely shocked as his clothes fell away from his body. The girls shrieked in shock and embarrassment.

"Dude, what the hell!?" Sero called out. "Is that how you lost your pants a year ago!?"

Mirio still kept his smile, only for it to falter when he realized Izuku was still running at him, along with Ben.

"Oh, that's right. He already knows this little drawback to my Quirk. And he's seen me naked before. And Ben has seen my exploits firsthand even before he became an official student at UA."

"WHITE SPARK!"

Using the [Plume-Plume Fruit], Izuku transformed his entire body into a cloud of dense smoke, shocking Mirio as it surrounded him. Ben then cut through with some of the smoke being pulled into his fists to form makeshift gauntlets which he used to punch Mirio, only for the attack to phase through his body.

"Well, ain't that impressive." Ben thought before looking down to see Mirio still had his shoes. "Given his Quirk somehow lets him phase through solid objects... It seems like he can actively control which parts of his body are still solid."

He coated his leg in electricity and delivered a shocking leg sweep, shocking Mirio as he lost all sense of balance.

"Well, didn't see that second attack coming. First blood goes to you, as the saying goes."

He got up and already was intangible again as Yuuga, Sero, and Kyouka tried their attacks, only for them to phase right through him. He quickly dashed off, showing shocking speed.

"Probably better to keep my focus in this fight. So I'll start with the long-distance fighters."

Izuku, Katsuki, Ben, Hilda, Penny, and Kirby looked shocked as most of their classmates were taken down in seconds.

"This guy doesn't just have a powerful Quirk, his physical skills are top-tier as well." Shoto realized. "We took this guy for an idiot, and maybe he is. But he's an idiot who can get serious when the situation calls for it."

"That's the benefit of the work-study. Mirio was complete garbage before then." Ryuji explained. "But he took on a work-study with a hero and built himself up. Same with Tamaki and Nejire."

Mirio finished the job of knocking out the other students, grabbing his pants for a big pose.

"POWER!"

"This guy's gonna give us a run for our money..." Kirby realized.

"I was hoping he'd slow down trying to fight our friends, but he doesn't even look winded," Hilda said.

"Even Aoyama's laser passed through him without effect," Penny noted, "Meaning it's not just physical objects he can phase through. Fire and explosions may not be enough."

"Everybody still has a weakness. This whole time he hasn't slipped into the floor despite being seemingly intangible, and he's always made direct contact when attacking." Ben pointed out. "I was able to sweep kick him when me and Izuku rushed him earlier, so there are parts of his body that are still solid no matter what he does. We might be able to counter him in the brief instant his body turns solid just as he's about to attack."

"You sound like you know what you're doing, but let's see if you can find a way to win!" Mirio noted.

He started running before quickly slipping into the ground. This immediately caused everyone to stand their ground.

"Where's he gonna come up?" Kirby wondered.

Izuku, Katsuki, and Ben closed their eyes, using their Observation Haki while Hilda focused with [Danger Sense]. Suddenly, their danger signals went off, and reacted accordingly.

"BLACKWHIP!" Hilda shouted as she spun around and fired the attack behind her.

"Whoa, they predicted where I'd pop up. Pretty smart. But not enough."

Mirio started to phase through the whips, but Hilda had been expecting this, readying her palm for a sumo strike.

"FA JIN!"

Mirio was shocked as he got knocked back by the force, as was the rest of the Big Three and the Phantom Thieves.

"How? Not even wind can affect Mirio when his Quirk is active!" Nejie asked.

"But kinetic energy can, otherwise he wouldn't be able to move while intangible." Aizawa pointed out. "Yasakani picked up on that and used a skill she developed to unleash a powerful kinetic shockwave created by raw strength. I used to think Mirio was the closest to being the #1 Pro Hero after All-Might retired. But now... I'm starting to think some of my kids have a better chance."

"That's the second time you've caught me off-guard. I was already aware that people could try and counter me when I made my attacks, so I trained to work around that. But what you did just now was something I didn't expect." Mirio said as he picked himself up before entering a battle stance. "I think I did it wrong the whole time. I should have just been fighting you."

"And me." Izuku smirked as he coated his fists in Armament Haki.

"Trust us when you see that we have more than one way to get past an intangible person." Ben added.

It took about an hour but the battle soon ended in a stalemate. Mirio and Izuku fell over, breathing heavily as Ben and Penny tried to support each other while Hilda groaned, flopping on her back.

"I need...a thousand burgers after this..."

"Mirio's Quirk, [Permeation], is something else, I gotta say..." Ben said, wiping sweat from his forehead.

"Yeah, and even when we bypassed his intangibility with Armament Haki, he was able to jump back on his feet." Hilda groaned as Ochako fanned her. "Whatever training he's doing is something else."

"You were even able to phase through the floor." Izuku noted as he and Mirio helped each other up. "Do you ever get stuck there if you black out and lose control of your Quirk?"

"No, thankfully. When that happens I pop right out into the nearest empty space. And much like kinetic energy, I can still be affected by gravity while intangible."

"I noticed you can activate certain parts of your body to be intangible at will," Penny noted.

"Yeah, it's necessary. When I'm phasing through a wall I need to concentrate. Start with one leg solid, then as I phase through I make the other leg solid and pull the rest of my body through. It's a bunch of little steps that I need to keep in mind. When I was younger I was always falling behind because I couldn't properly control my Quirk. I needed to learn to make combat decisions on the fly and predict my opponent's next move. That's the benefit of experience. And experience is the benefit of the work-study."

"Unlike internships, we're not treated as guests, but sidekicks or even pros. We're considered official employees of the agency." Makoto explained as she stepped up. "It can be scary quite often. Pro Heroes can get hurt, and there are times when you're forced to watch people die. But that's important to build up the experience needed to protect the people.

Yusuke nodded. "No classroom will give you that, not even UA. We took all that we learned and turned that into power."

"You guys are pretty strong, but just imagine how much stronger you'd be once you get some real-world experience," Mirio said to Izuku, Ben, Hilda, Penny, Kirby, Katsuki, and Shoto before turning to the rest of their class. "The same goes for all of you. You could get to a point where you wouldn't just defeat villains, but flat-out cream them. You feel me?"

"Yeah, I'm feeling it!" Eijirou said as he and the class applauded.

Both Twice and Airi led Overhaul to the factory where the League of Villains had their base. The Yakuza Leader couldn't help but scoff at the sight of it.

"This is your base? It's a complete filthy hovel."

"Only from the outside. We make sure to keep it clean inside." Airi said. "After all, it's equal parts planning center and hangout."

Just as planned, Twice spoke with Tomura about keeping Motoko out of the meeting to keep Overhaul in the dark about their intentions.

The door to the factory opened, revealing Tomura sitting at his usual table. August standing beside him holding a wizard's staff that had an orb with an omega symbol on the head.

"A pleasure to meet you, Overhaul. You can call me by whatever name you wish, Tomura Shigaraki, Tenko Shimura... But the title I have taken to represent my new power is The Ultimate Lifeform."

"It's been a while, Kai Chisaki." August hummed. "Or do you prefer to go by Overhaul these days?"

"You know this guy, Gramps?" Parten asked, digging into his ear.

"I have seen him once or twice in the past. He is part of the Yakuza."

"I'm not sure I get it. How is this guy different from our own League of Villains?" Spinner asked.

"It's organized crime. Like the mafia back in the States." Mr. Compress explained.

"Indeed. Overhaul is the young head of the Shie Hassaikai." August said.

"But in recent years such organizations were put down by All Might, yes? And heavily monitored too." Thrax noted.

"To be fair, All-Might was simply the final nail in the coffin." Overhaul said. "As much as I hate to admit it, crime syndicates like mine have been on the decline since the Dawn of Heroes. But I'm hoping to change that."

"Ah, planning a revolution are we?" Tommyrod asked. "Getting bold after All-Might and Sister Sage disappeared for their little honeymoon?"

"All-Might's always put his life on the line when it comes to saving people and fighting crime. But now he has more to lose, and more to live for." Overhaul pointed out. "Between that, the power vacuum left by All For One's final defeat and the passing of Thanoseid, as well as a little secret I stumbled across, I hope to recreate the golden age of the yakuza. No longer will we be just rent-a-thugs for any villain organization that wants to hire us, that I can promise you."

"Careful, promises have a bad habit of getting broken. But at the very least I do admire your ambition." Tomura warned. "And seriously, if you need some help getting your crew up, I have connections to the Dark Knights themselves. I even have them on speed dial."

"You're talking like you intend to be the next leader of the darkness. Quite the ego for someone so young. And the people you've surrounded yourself with." Overhaul noted as he looked at the group. "A faggot, a bunch of mentally ill freaks, drug-addled homeless bums..."

"Hey, I like to think I'm perfectly lucid and I wasn't homeless!" Spot pointed out indignantly.

"Got any more of your barbed words?" Vetto huffed. "Or would you like us to show you why you shouldn't trifle with our group?"

"Stay your hands, ladies and gentlemen," Tomura said, placating them all. "Just because our guest is making a bad first impression doesn't mean we get to do the same. Unless you believe we already have just by being who we are?"

"What? A bunch of walking diseases?" Overhaul replied.

"You say that like it's a bad thing." Scarepion quipped, grinning behind his mask.

"Gotta say, you're barking up the wrong tree, baby." Thrax chuckled. "We may be criminals and scum but even we believe in fairness. We're just here to make sure there are still lots of bad germs for the anti-bodies to fight against."

Overhaul raised an eyebrow. "Seriously? Here am I working on a plan to get rid of heroes, and you're trying to balance the numbers?"

He was met by raucous laughter from the entire League. Saiko was cackling as she and Garie supported each other, hands on their stomachs as Micha was just rolling on the floor howling like a hyena.

"Get rid of heroes? Impossible." Tomura asked, wiping a tear from his eye. "You might get rid of the profession, but it's impossible to get rid of the concept. The term 'hero' has existed for centuries, long before actual superheroes arrived."

"Think whatever you want, but at least I have a reasonable long-term goal," Overhaul pointed out. "Either way, my plan requires funding. The problem is, not many people are willing to invest in a small-time outfit. But your name already has widespread recognition. And for all the crap names I gave your members, I will acknowledge that they are professional villains. So I have a proposition, join me and I can show you how to make the most out of the tools you have."

"Tools? Really?" Deidara chuckled, shaking his head. "We're more than tools! Someone like you doesn't understand the art we bring!"

Deidara sent out clay birds at Overhaul as he rushed to deliver a punch to his face. However, Overhaul removed one of his gloves and then thrust his hand into Deidara's face. The League could only watch in horror as the Mad Artist's top half exploded in a gush of blood, leaving only his bottom half to flop forward lifelessly.

"DEIDARA!" Twice screamed in horror.

"The hell kind of Quirk is that?!" Nnoitra said in disbelief. "He blew up Deidara like he was a water balloon or something!"

"Just so you know, you made the first move." Overhaul said dangerously as he started working to clean the blood and viscera off him. "Damn it. Now I'm all filthy. I hate the aftermath my Quirk creates."

"You fiend!" Mr. Compress snapped as he rushed forward, uncompressing a knife from one of his hidden marbles, and grabbed Overhaul.

"Compress, no!"

"Don't touch me!" Overhaul snarled, swiping with his hand.

Mr. Compress could barely even let out a cry of pain as his entire arm exploded. Luckily, Magne was able to use her [Magnetism] Quirk to pull him away.

Tomura growled as he stood up from his seat and, as if time had been skipped around him, appeared in front of Overhaul before turning his fist into a rhino's head, which he used to knock the Yakuza into the back wall.

"August, can you fix Deidara?!" Mustard asked.

August sadly shook his head. "I cannot...As powerful as [Omega Infinity] is, even it has its limitations...the least I can do is make sure a part of Deidara remains with us."

The omega orb on his staff glowed orange with the power of the Soul Link, attracting Deidara's soul energy into it. August closed his eyes and said a silent prayer.

"Get in here!" Overhaul called out. "I need reinforcements!"

Several more Yakuza burst into the warehouse. However, the League wasn't going to take the death of one of their own sitting down and moved in to attack.

Nnoitra drew his extra arms and scythes and dashed at blinding speeds with Soru, dodging something he could see out of the corner of his eye, bullet casings dropping not far away. Before Overhaul's eyes, several of his men suddenly dropped down...in pieces.

"A flashy trick...but not flashy enough!" Leiur said as she created and flicked several stone coins like bullets, piercing through more of the grunts. Thrax pierced his glowing index claw into one grunt's chest and watched as he burst into flames from the inside out thanks to his Quirk, [Burning Touch].

Parten turned his arm into a mass of multi-eyed tentacles with razor-sharp teeth and grabbed several grunts before pulling them into his body, which bulged and twitched before his torso turned into a gaping maw that barfed out blood, melted bones, and organs.

Airi created a minigun with her tattoos and opened fire on the grunts, being backed up by Garie, who sent out water and ice bullets while Micha fired fire crystals from the holes in her palms. Mustard sent out a wave of his gas to make a cloud to hide his comrade's attacks while Spinner lunged with a kukri.

"Things are getting too out of hand!" Twice cried. "FIGHT! FIGHT! FIGHT!"

One man in a white hood and plague mask covering his face landed near Overhaul, a shard of glass wedged in his shoulder thanks to Saiko.

"Sorry boss. I tried hitting the crazy girl with red hair, but she was too fast."

"Where the hell did your friends come from?" Airi asked as she dispelled the tattoo minigun. "We made sure we weren't followed."

"By my theory, they must have had someone with a Tracking Quirk." Mr. Compress said as Scarepion and Garie moved to tend to his lost arm.

"That was a complete mess. Seriously, I only killed one of your guys, did you have to kill half the crew I had on standby?" Overhaul scowled before turning to leave. "Killing each other is counterproductive. How about we cool our heads and try again when we're all a lot calmer?"

The Yakuza headed out, though they at least left a business card behind. Motoko stepped out of hiding, having been hidden by Phara bending air molecules around her to make her invisible.

"I'm sorry for what Kai did...He was always respectful of my father, the Oyabun."

"It is alright..." Tomura said. "Deidara at least died fighting."

"Well, this is a fine mess you've gotten yourselves into."

The League got on guard as they looked around for the source of the voice.

"Who said that?"

"It's me."

Suddenly, everyone realized that someone had appeared out of nowhere. He was a tall, lean gentleman with slicked-back, grey hair; reaching to the back of his neck. His entire face is, however, covered by a white mask with a mischievous smirk running from its cheekbones down to, slightly above, the jawline and arching back up to his opposite cheekbone. Granting him visibility were two crescent-shaped spots flowing downwards, forming a wicked portrayal along with the mouthpiece.

"It's you..." Mr. Compress noted as he stood up.

The man tipped his top hat. "The name is Hiruko, Kagetane Hiruko."

"How did you get in here?" Spinner asked.

"There WAS a front door, of course," Kagetane said as if it was the simplest thing. "Sorry we came at such an inappropriate time."

"I'm sorry, 'We'?" Tommyrod asked.

Suddenly, a tiny girl no older than 10 walked up beside Kagetane. She wore a small dress with many intricate designs in the middle areas, connected to a bottom skirt that covered her entire lower body.

"Sorry to intrude. Kohina Hiruko, Ten years old." The girl said, giving a curtsey.

"Not only is she my daughter, she's also my partner in crime." Kagetane said, patting the girl on the head.

"What do you want?" Tomura asked.

"Why, we were simply on our way to join your merry little band of misfits. Of course, we should have picked a more appropriate time to come."

"Yeah, probably..." Mustard said. "Dammit, Deidara was one of our best guys..."

"Don't worry, if it's revenge you're seeking, I can help you get it." Kagetane said reassuringly. "In return, I simply ask that me, my little dove here, and a few other friends of ours be allowed entry into your crew."

Tomura nodded. "We'd be more than happy to have you."

"You heard him, boys! Come on out!" Kagetane said, clapping his hands as three tall, menacing figures jumped down from the shadows.

"Whoa..." Spinner muttered.

"They look just like..." Magne began.

"Yeah, I know, we get that a lot." One of the figures said, having wild blue hair with crystalline light purple tips, black eyes with red pupils, and an X across his chest.

"We figured it was nice of us to model ourselves after our favorite characters." Another of the figures said, having a broad-shouldered muscular build, white gloves, a mustache, and a cap.

"For me in particular, it was practically what I was born into." The last of the three figures said, carrying a pendulum and looking like a muscular version of the Pokemon Hypno with hollow glaring black eyes.

"I've heard of your exploits..." Scarepion noted. "You certainly know how to scare...I think you all will be welcomed in quite nicely."

The Big Three are accompanied by the Phantom Thieves from Persona 5!

The League loses Deidara but get new members in Kagetane Hiruko from Black Bullet, his daughter Kohina, and three figure that many Creepypasta fans might recognize from the descriptions I gave.

Lastly, Overhaul is about to get FUCKED six ways from Sunday!
