My Hero Academia Shall Know Pain

"Shinso, you can go sit over there. We should have enough space to add you in here." Aizawa told Shinso where his seat was.

The practical exam was over, the students that passed were excited for the training camp and the ones that didn't were depressed. Shinso was extremely happy that he got into the best hero class, but he quickly learned that the teacher is less then motivated to teach them and his new classmates were quite eccentric.

"Alright, about the practical exam. A few people didn't pass, I'll tell you who didn't right now. Sato, Eijiro, Mina, Denki, Bakugo, and Izuku failed to pass." Aizawa said.

"What? B-but Aizawa-sensei, didn't we beat both of the pro heroes? Why did Yahiko pass the exam then? He was on the same team as us?" Izuku asked, visibly confused. He and Bakugo were covered in bandages, they took a beating during the exam.

"If you want to know so badly, then I'll tell you all of the things you did in the exam that only convinced the teachers to fail you and Bakugo. The first thing you did wrong was doing nothing at all, you didn't do anything to help your team. You didn't help them fight nor help them escape, you simply ran away whenever the heroes got close to you, but you didn't head toward the exit. You even left one of your teammates behind just to save another, leaving that teammate in a dangerous situation that he had to deal with by himself.

Bakugo, not only did you show hostility and was extremely uncooperative with your team, you even launched an attack knowing that your teammate would get hit too. Well, at least you did something. Oh, don't forget that you two weren't the ones that defeated the heroes. You also didn't pass the exit gate, only Yahiko did." Aizawa listed the numerous fuċk ups they made during the exam.

"That's bullshit! If that bastard is strong enough to fight two pro heroes on his own then why did you pair him with us!? How could we help in a fight like that? That rabbit bitch was using the buildings as her personal playground, All Might created tornados with every punch, and this fuċker made a goddamn meteor!"

"Honestly, if we knew that Yahiko was that strong then we would've had him fight a hero agency or two on his own. If you have anymore complaints then bring them to Nezu, I don't give a shit about how your exam went anyway. Speaking of Yahiko, are you okay?" Aizawa asked out of nowhere.

"I'm fine, why do you ask?" Yahiko replied.

"Mirko kick your arm off, losing a limb must've hurt right?"

"No, I didn't feel anything. I lost a mechanical arm, not my own." Yahiko ȧssured him.

"Okay, we're getting off track here. About the training camp, everyone gets to go." Aizawa said, making the students that failed perk up.

"The students that failed will have to take tests there when they have some free time, you guys also have to bring these items with you. Make sure you have these supplies, if you expected the school to pay for everything then think again."

Everyone looked over the list and were surprised by the amount of stuff they needed to buy. One of the girls suggested that the whole class should go shopping at the mall.

"Will you come shopping with us too Yahiko-kun?" Ochako asked hopefully.

'This is where Izuku gets molested by Tomura, I can use this chance to actually catch Tomura.' Yahiko thought to himself.

"Sure, I'll go."

"Wait a sec, someone wants to see you Yahiko." Aizawa suddenly called out to him.

"Who?"

"Any minute now." Aizawa replied.

Yahiko looked at him in confused before he finally figured out who wanted to see him.

'Jesus fuċkɨnġ christ.'

"Yahiko! Good to see you again." Mirko said as she burst through the door.

"Why is she still here?" Yahiko asked Aizawa, who had a shit eating grin on his face.

"She's a teacher now, she has every right to be here." Aizawa replied lazily.

"I thought that she was only going to fight me once and leave, why is she a teacher? She'll just try to attack me whenever she gets the chance, why would Nezu ever hire her?"

"Because I recommended her."

"Why, why would you do that?"

"Don't you think it's kinda rude to talk about me when I'm right in front of you?" Mirko suddenly chimed in.

"Think of it as payback, always causing trouble for me, so she will always cause trouble for you. 'An eye for an eye' I guess." Aizawa said, completely ignoring Mirko.

"You fuċkɨnġ suck."

"You can thank me later, now go shopping with with your acquaintances."

"Acquaintances?"

"I say acquaintances since it's hard for me to put the words 'Yahiko' and 'friends' in the same sentence."

"How are you a teacher?"

"I don't even know, so hurry up and go so you can stop bothering me."

Yahiko paused for a second, then he looked at Mirko. She looked dejected after being ignored for so long, it's either that or her injuries are getting to her. She hasn't fully recovered after all.

"Mirko, Aizawa-sensei taught me how to fight. If you beat up my teacher then you'll have a better chance at beating me." Yahiko said suddenly, making Aizawa cough up the coffee he was drinking.

Mirko looked over at Aizawa and had her usual grin on her face.

'Time to go.' Yahiko thought as he grabbed Himiko and walked out as fast as he can.

"Let's fight!" Mirko yelled excitedly.

"You son of a bitc-" Aizawa tried to say something but was kneed in the stomach.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"What was that all about?" Denki asked.

"Revenge obviously, it's what he gets for recommending that woman in the first place." Yahiko replied plainly.

Almost the whole class were at the mall, the exception being Bakugo. He obviously didn't want to go shopping with Yahiko and Izuku.

The class were confused at how the situation escalated so quickly. Their teacher was simply telling them what they needed to bring to the training camp one second, then he was fighting another teacher the next.

"Are we going to get swarmed again?" Jiro questioned herself, she didn't want to get stuck in a large crowd of people.

"You'll be fine, Yahiko is like a bug zapper for humans. They won't approach us as long as he's here." Himiko spoke out loud as she pointed at some people as a demonstration. A few people were about to walk towards them but quickly stopped in their tracks when they saw Yahiko in the group.

"It's like having your own personal bodyguard..." Sero said in amusement.

"I know right? Now then, what are we standing around here for? Let's go shopping!" Himiko said excitedly as she ran off in a random direction, Yahiko sighed and went after her.

The class split into little groups and went after what they needed, leaving Izuku and Shinso behind.

"U-um, hello." Izuku stuttered awkwardly.

"..." Shinso didn't bother to say anything and left Izuku standing there by himself.

Now Izuku stood alone at the mall, with a hooded man shadowing him. The hooded man walked right up behind him and put his left hand around Izuku's throat.

"!!!"

"Tell me what you know about Yahiko Bubaigawara, or else." Tomura said in a low voice, he had brought Izuku to a bench so they could sit down together.

'This fuċkɨnġ idiot, he just got his ȧss handed to him and he goes after one of the U.A kids when he hasn't even recovered yet. Is the league of villains going to be okay with a leader as dumb as this?' Deidara scoffed at the fact that he has to protect a suicidal person. He silently watched them from the second floor of the mall.

A few minutes pass by and Deidara quickly grew bored, he didn't want to spend his time here and watch some guy molest a kid. His mind quickly wandered as he started thinking about his art.

While Deidara was thinking of ways to improve his art, he suddenly noticed someone dangerous approaching Tomura.

'Shit! It's that crazy kid with the strong quirk! He's headed towards Shigaraki, I can't let him get his hands on him!' Deidara thought as he pulled out some clay from his pocket and began to quickly knead it with chakra.

A small snake came out of the mouth on his hand and silently slithered closer to Tomura and Izuku. It went pass them and slithered in front of Yahiko's path.

'C1!'

A large explosion was heard throughout the mall, it destroyed a large chunk of the floor. Shrapnel flew everywhere, it impaled several unlucky civilians and the lucky ones were killed instantly.

The explosion pushed both Tomura and Izuku to the ground, they skidded several meters before coming to a stop. Deidara quickly jumped down from the second floor and called All For One on a throwaway phone.

"Hey, Tomura fuċkėd up again. I need you to get us out of here quickly unless you want us to to get caught, hmm." Deidara said as he grabbed Tomura's collar and looked at the explosion he just made with a satisfied expression on his face.

'Universal Pull.'

Deidara suddenly felt his feet leave the ground, he looked over to where his explosion had occurred again and saw that Yahiko was standing there with his hand outstretched. His clothes were ruined, they were practically rags now. He was bȧrėly affected by the explosion, which made Deidara gasp in shock, then anger overcame him. That is, until he noticed the receiver in Yahiko's hand.

'He's trying to kill me, he really isn't made for the hero industry is he?' Deidara thought to himself.

Yahiko stabbed Deidara in the ċhėst, his receiver was visible through his back. Deidara's skin and clothes suddenly turn into a pale white color, the clay encased Yahiko's arm and trapped him.

"I really wanted to put some explosive clay in that clone you know, make some more art so that people can learn to appreciate it more hmm. But hey, we can't alwa-" Deidara suddenly spat out some smelly black liquid from his mouth, the same happened to Tomura. It enveloped both of them quickly, they were gone the next second.

'Not again, at least I know that a new enemy is here. I can make precautions against Deidara, but I need more information about the league.' Yahiko thought to himself as he yanked his arm away from the clay clone, making it fall apart.

"W-who was that?" Izuku said nervously, he looked around himself and vomited. He's never seen a person's guts before, so having several guts lying on the floor around him made him puke.

"What happe- Oh my god!" Momo said as she ran over to them, she immediately stopped and covered her mouth. She nearly puked at the sight, but she kept it in and analyzed the situation. It was obvious that a bomb had went off and had killed several civilians, but she was wondering why Yahiko had his strange weapon in his hand and why Izuku had a hand print on his throat.

The rest of the class had finally arrived at the scene and most of them had trouble holding their lunches in.

"A terrorist, had someone teleport him out of here, I was going to deal with him but he got away." Yahiko explained as he looked over at the destruction around him.

"Olay, why does Midorya have a hand print on his neck." Ojiro asked as he went over to a nearby trash can to throw up.

"T-the person that attacked us at USJ interrogated me! He was asking me questions about your quirks and then the explosion happened suddenly, pushing us both down to the ground. The bomber saved him from Yahiko and they both disappeared in some sort of black liquid." Izuku explained hastily.

"So that terrorist must be apart of the league of villains as well, are you two okay?" Sato asked worriedly.

"I'm okay, and I'm sorry that I told him about your quirks guys." Izuku apologized.

"How much did you tell him?" Yahiko suddenly asked Izuku.

"Huh? Uh, I told him what I know so far about each of your quirks, like your strengths and weaknesses. I also told him my theories about them..." Izuku trailed off when Yahiko started to walk towards him, making Izuku cower slightly.

"What about my abilities?" Yahiko questioned.

"I only told him what the information I have gathered so far, since I actually don't know what your quirk is. Like the possibilities of your robotic quirk and all of the creatures I've seen you make so far." Izuku's voice was getting quieter as he spoke, Yahiko was standing a few feet away from him.

"I also told him about how you absorbed Kacchan's explosion and how you fought two pro heroes and won." Izuku suddenly felt something cold press against his forehead, he realized that it was the receiver that Yahiko was holding. Izuku yelped in surprise and fear, he fell down on his ȧss. He felt his forehead and sighed in relief when he figured out he was fine, but quickly gasped in fear again when the receiver was stabbed down into the ground near his crotch.

'They'll definitely put more effort into eliminating me now that they know I'm strong enough to beat some of the teachers in U.A, or they'll at least try to hurt someone close to me. If they get their hands on Himiko because of this idiot right here, then All For One will be the least of U.A's concerns.

"W-what are you doing!?!" Izuku asked in a shakey voice.

"I highly recommend that you learn to keep your mouth shut, you really sold us out just to save yourself. You're the most pathetic excuse of a aspiring hero I've ever seen, so don't let me catch you trying to analyze my quirk anymore. Let's go Himiko." Yahiko said as he walked away with Himiko by his side, leaving the other students there to deal with the mess.

"That was pretty fun, so who got away from you this time? Can they use chakra like you? They must be pretty bold to attack you in broad daylight, what do you think their blood will be like?" Himiko asked curiously, her smile never left he face.

Yahiko looked over to her and chuckled lightly before he wrapped his arm around her waist to bring her closer.

*Sniff*"You smell like clay."
