The alley was filled with trash and the four U.A. students found some rope to restrain the Hero Killer. Izuku with his great thinking and comprehension told them that they need to remove all the weapons from his pockets and everything to make sure he doesn't try to use them to escape. They agreed and removed the collection of smaller knives and jagged daggers and Y/N took the sword away and broke the blade in half. Shoto tied Stain up tightly to make sure he wouldn't break loose.

"Native, can you move?" Izuku asked the pro hero.

"Yeah, I'm okay now. You hurt your legs, right? Let me do this at least." Native said and hoisted Izuku on his back.

"T-Thank you very much."

"That's my line..."

Tenya approached his friends about to help when Y/N raised her wrapped left hand up to stop him and already dragged Stain with her right hand that's not injured with the rope.

"Your arms are injured. So let me do the job."

"Sorry. Even though I'm a pro, I was just in the way." Native apologized.

"No, I don't think you could've done anything one-on-one with the Hero Killer's Quirk." Izuku said from Native's back. "He's too strong."

"Fighting three-on-one with the guy making mistakes himself and we still lost. The only reason why any of us came out of here alive is Y/N." Shoto commented.

"You all would have been dead without my help. It's a good thing I followed your scent. But since TENYA is alive, I would LOVE to punish him since he broke our promise to not to go near that hero killer." Y/N said, smirking at the end as she deviously think about the torture she likes to make him do, lots of situps, weight lifting, and more that are part of exercise.

Tenya gulped in nervousness as he had hoped that she will forget, but he was wrong. Shoto and Izuku raised their eyebrows of what kind of punishment Tenya is going to receive.

"Let's quickly get him to the police-" Native cut in, but was soon interrupted.

"Wha...? Why are you here?"

Across the street is the short old man with the yellow cape.

"Gran Torino!" gasped Izuku, only to be kicked in the face as the man shouted at him.

"I thought I told you to stay seated on the bullet train!"

"Who's that?" Shoto asked.

"The hero I'm interning with, Gran Torino, but why?"

"I was told to come here all of a sudden. Well, I don't really know what's going on, but I'm glad you're ok." Gran Torino said no longer mad after Izuku apologized.

A few more heroes came and stood in front of them. Y/N looked back at Stain to see if he's awake, but he's not moving still. She gripped onto the rope to make sure he is held.

"It's around here!"

"Endeavor told us there was a request for help here, but..."

"H-Hey, this is..." one of the pro said looking behind Y/N.

"What?"

"Hero Killer, Stain. We got him fair and square." Y/N spoke up. "Call the police or whatever."

The pro heroes did what they're told and they talked to the three boys while she stayed with Stain. Tenya walked up to his friends as the pro hero tried to stop him from moving after seeing him bleed badly.

"The ambulance will be here soon! Until then..."

Tenya bowed to them with tears dripping from his eyes.

"You three. I am truly sorry." he said, looking at you and the boys.

Y/N frowned even though she's still mad at him, she understand he was trying to take down that villain who took away his brother from hero duty. Though, revenge will make things worst as she always told herself from all the suffer she had been through.

"I'm sorry, too." Izuku said. "Even though we're friends..."

Tenya rubbed away the tears. "Yeah."

Y/N was about to say something when-

"Get down!" Gran Torino expectedly shouted, breaking up the moment as everyone turned their head up to see a Nomu plummeting down.

One of it's eyes were missing and bleeding as it ooze off of its site and its claws stretched out to pick its next victim. A gust of wind brushed past the group. The gasp was heard and they looked up in fear. Y/N was lifted in the air by Nomu who snatched her away.

"Y/N!!!" the three boys shouted.

"Let...me..go!!!" Y/N yelled, bringing her claw out and stabbed its neck, making it scream and digged its claws onto her back.

She screamed in pain and she tried to pry it off. Suddenly, she felt it freeze and began to fall to the ground along with her. She heard a voice and turned to see Stain running towards her and Nomu.

"In this society overgrown with fake heroes... and the criminals who save their power around idly..."

He came down on Nomu with his hidden blade raised and struck down on its exposed brain. He was riding the body as it crashed down and pried Y/N's body off from its claws and gently put her down and held her there.

"...should all be purged. This is all... to create a more just society."

"Why are you all standing around in a group?" she heard someone boom and turned to see the flame hero she still doesn't like. "The villain should've escaped this way."

"Endeavor." Stain growled as his mask fell off to reveal his terrifying face that made her classmates and the pros scared.

"Hero Killer!" smirked Endeavor as he brought out his fire fist.

"Wait, Todoroki!" Gran Torino shouted.

"You fake..." he stomped on the ground as the red moon glowed behind him along with his eyes that glow red, he's a more scarier villain than other villains. "Come! Try and get me, you fakes! The only one I'll let kill me is the true hero... All Might!"

Those were his last word and Y/N heard the falling of his blade and nothing else. They were shocked to see him unmoving as his body of where he stand stood in place like a statue with his mouth agape.

"He's... He's unconscious..."

Y/N heard later that a broken rib he had had pierced his lung and he hadn't licked anyone's blood, but at that place, for that one moment, the hero killer was the only one who stood up to fight against his opponent.

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

"Were you able to sleep, Midoriya?" Shoto asked.

"No, not really. I didn't think so." Izuku replied.

"Me neither." Tenya said.

"Good for you, Tenya. Maybe that will teach you a lesson for being reckless. I didn't get to sleep either. Just thinking." Y/N said.

"Thinking about it now, we did something amazing, huh?" Izuku said.

"Yeah." Shoto agreed.

The four of them had been stuck in the Hosu General Hospital for several hours. Y/N only had a couple of bruises and her left hand was bandaged up while the boys had more or less wrapped up bandages, well mostly Tenya.

"It's a miracle that we're still alive." Y/N said.

"Yeah." Izuku nodded, looking at his bandaged leg. "With my leg like this, he probably could've killed us if he'd wanted to."

"Yeah. We were obviously left alive on purpose." Shoto said, looking at his bandaged arm.

Y/N looked at her left hand to where Stain had stabbed as she wondered how come he didn't try to kill her if she was wanted by the League of Villains and why did he save her from the Nomu.

"You're amazing to have been able to face him after all the murderous intent directed at you."

"No, that's not it." Tenya said. "I..."

"Oh, are you wounded kids awake?" the voice said.

They turned to see Manual, Gran Torino, and Ryukyu. Izuku, Y/N, and Tenya exclaimed their intern's name.

"Kid, I've got a lot of complaints for you." Gran Torino said, walking up to him.

"Oh! S-sorr-"

"But before that, you've got a visitor."

A tall figure came looming in the doorway and it revealed the tall man in a black suit with the face of the dog. Y/N wondered if it's normal to have a dog face like that.

"Hosu's chief of police, Kenji Tsuragamae."

Tenya and Shoto stood up from their bed, making you confused and Izuku about to move when Kenji told them to stay seated with a 'woof' at the end. Y/N for some reason find it weird and a bit adorable to hear that from the man who is literally a dog.

"You must be the U.A. students who brought down the hero killer, right?"

"Yes."

"Regarding the hero killer we arrested, he had fairly serious injuries, with burns and broken bones, and is receiving treatment under strict guard, woof. Since you are U.A. students, I'm sure you already know that when superpowers were still becoming the norm, the police attached high importance to leadership and standards and made sure Quirks were not used as weapons. And then, the profession of 'hero' came in to fill that gap, woof. For an individual's use of force and power that can easily kill others-"

This made Y/N tense and quickly look down. The boys looked at her concern as they listened to the chief.

"Actions that normally would be appropriate to denounce- you be accepted officially is thanks to early heroes who followed the ethics and rules of the profession, woof. Even up against the hero killer, for uncertified individuals to cause injury with their Quirks without specific instructions form their guardians or supervisors is a clear violation of the rules. You three boys, and the pro heroes Endeavor, Manual, and Gran Torino must receive strict punishment."

"Hold up." Y/N spoke up, looking up at him. "How come they get to receive punishment? I also use my powers with Ryukyu's permission."

"Like you said, you were the only one of the U.A. students was given permission to use your Quirk by Ryukyu. You're in clear as well as Ryukyu." Kenji turned to her.

"Still though, I think it's unf-"

"If Iida hadn't done anything, Native would have been killed. If Midoriya hadn't come, the two of them would've been killed." Shoto spoke, clearly showing anger. "No one realized that the hero killer had appeared. Are you saying we should've followed the rules and watched people get killed?"

"Shoto." Y/N stopped him from taking step further.

"Are you saying that as long as it turns out right, it's okay to bend the rules?" Kenji asked.

"That's not the point. He's trying to say that it's a heroes job to save people who are in danger. A true hero would never abandon those who are in need of help and they fight for what's right, instead of following the rules. People would have done the same, even if they know it's against the rules, they have to just go for it without hesitation or else they would be ashamed of themselves for not doing anything." Y/N spoke up as all eyes were on her, shocked for such strong words.

"You have a strong and kind heart, L/N." Kenji said. "The punishment and such would only happen if this were made public, woof. If this were to make it to the news, you probably would be applauded by the citizens, but you would not be able to escape punishment. On the other hand, this is a bit underhanded, but if it is not made public, the burn scars and broken bones would support Endeavor and L/N being the heroes who saved the day. It would end there, woof. Thankfully there were very few witnesses. This situation would be crushed here, woof."

Y/N looked at the boys with a frown on her face as she find it unfair that she's only one not in touble.

"Personally, I don't want to be the one at fault with promising young ones because of one big mistake, woof."

Manual spoke up with humorous little tears prick in his eyes.

"Either way, we will need to take responsibility for being negligent in our supervising duties."

Tenya stood off from his bed and walked in front of Manual and bowed to him.

"I am truly sorry."

"Alright. You'll cause trouble for others! If you understand, don't do it again!" he scolded, softly chopping on Tenya's head.

"I won't!"

Shoto and Izuku bowed as well, apologizing.

"Due to the fairness of adults, you will not be able to receive the praise you probably would have gotten, but at least, as someone who also protects the peace, I can say thank you." Kenji said and bowed to them.

"Please start with that next time..." Shoto muttered

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

At Fourth Kind Agency, Eijiro and his buddy Tetsutetsu were changing their clothes to their hero costume when Eijiro got a reply from Izuku.

"It was at Hosu City, so that location was an SOS after all, huh?" he said and sighed in relief. "I'm glad I reported it."

He then got another reply and it was from Y/N. And what she wrote in the text made his eye widen.

"She's in the hospital?! From Hero Killer?! And she injured her left hand!!" he shouted in shock.

"Hey!" Tetsutetsu spoke up. "Fourth Kind's gonna hit you! Let's get going!"

Tetsutetu although was worried for Y/N after hearing Eijiro say that and hope that she's okay and fine.

"Wait a sec! I'm gonna reply to Y/N. I just want to know if she's alright."

And what he said next made both of them get punched in the head by Fourth Kind. Luckily, they hardened themselves without being in pain.

"Didn't I tell you that you must always be punctual?!"

"S-Sorry, sir!" they shouted.

"Alright, we're going on patrol!" Fourth Kind said.

"Yes, sir!"

Looks like Eijiro will talk to Y/N later once their internship is over.

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

Izuku walk into the room after getting off of the phone.

"Oh, Iida, Uraraka said..."

"Izuku. Tenya just finished getting examined." Y/N said, frowning toward Tenya.

"My left hand might have long-term damage..."

Izuku gasped in fear to hear such bad news.

"Both of my arms were pretty beat up, but it looks like the damage to my left arm was especially severe. There was damage to my brachial plexus. But it just means that I'll have trouble moving my hand and fingers and experience some numbness. Apparantly, there's a possibility that it can be healed with nerve transplant surgery." Tenya turned to face Y/N. "When I found the hero killer, I stopped being able to think and I didn't listen to what you said about being near him. The first thing I should've done was tell Manual. But I forgot myself in my anger. Being taken in by the hatred before you and trying to fulfill your own desires... That is the furthest from what a hero should be. I hate him, but he spoke the truth. That's why, until I become a true hero, I think I want to leave my left hand as it is. And Y/N, I won't break any promise from you ever again."

"Iida..." Shoto said.

Y/N awed at him in surprise and looked at her covered left hand. She never knew that he would thought of her that way.

"Tenya, I feel the same way. I'm still trying to move on from my past. But...let's become stronger..." Y/N said, staring straight into his blue eyes, bring out her left hand.

"Together." her and Izuku said at the same as he too feel the same as he brought out his right hand that had a scar from Sports Festival.

Tenya nodded as Y/N and Izuku nodded back in determination they have in them. Shoto stared at their hands with his eyes wide with a hint of fear.

"I feel... kind of bad..." he said, looking down.

The trio turned to look at Shoto in confusion.

"Shoto?" she asked.

"About what?" Izuku asked.

"I feel like if I get involved... other people mess up their hands..." Shoto looked at his hand as he's in full sweat with a clear look of fear on his face.

The trio looked at him again in confusion, not knowing what he's getting at until he told them.

"Is it a curse?"

They exchanged glances before they started laughing. This is the first time for Y/N to laugh and it is very enjoyable and fun.

"Todoroki, I didn't know you could make jokes!" laughed Izuku.

"No, I'm not joking. I'm like 'The Hand Crusher' or something."

This made the trio laugh even harder as they mocked at the nickname.

"'The Hand Crusher'!"

"Oh, you made my day even better!" Y/N whipped away her tear from laughing, showing her smile.

This got the boys to blush at her beautiful smile for the first time and they wished they could see it more.

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

Elsewhere, two days after the Hosu Incident, the hero killer's identity started being exposed from various angles.

"Recently, there've been less people willing to break the law. My buddies are all complaining about not being able to sell anything. It's a pain." the man with eyepatch on his right eye said.

"'Cause it's a serious crime to develop or sell support items and costumes without a license... On top of that, there have been rumours recently that legit support companies have been selling on the black market to people without hero licenses." the grey haired man said, holding the gun.

"I miss the days back before All Might... I was still young back then, too. The villains were wild and impulsive, and that turned into enthusiasm the whole country was teeming with. It was a good time. But then All Might appeared, everything changed. It's all thanks to that Symbol of Justice. Maybe it's time for me to retire."

"About that. Listen to this." the man said and started smoking. "Just between you and me, I know of a way to make some cash. I'm only telling you because I know you guys have quality goods."

He then showed his phone with a video in it and a title "Kill The Hero - Stain."

"Have you seen this video?"

"Huh? Who's this?"

"It's a video of the 'hero killer.' He's hot right now." he said and pressed the play button.

"Hero Killer: Stain. Real name: Chizome Akaguro. All Might's deputy left a deep impression on him, and he set his sights on becoming a hero. He enrolled in a private hero high school but was disappointed in the fundmentally depraved view of heroes taught by the educational system. He dropped out in the summer of his first year. Until the end of his teenage years, he called for a return to the old idea of heroes making speeches on the street until he realized resignedly that words had no power. For the next ten years, in order to fulfill his 'duty,'  he studied and trained in killing techniques on his own. During this time, his parents passed away, and that affair was considered non-criminal. He emphasized a return to the old idea of heroes. Heroes should not seek compensation. The title of  'hero' must only be granted to those who epitomize self-sacrifice. The present-day heroes are fakes who are all talk. He wanted society to realize this through purges one after another."

"Someone must be dyed in blood... I must take back what it means to be a hero! Come! Try and get me, you fakes! The only one I'll let kill me is the true hero... All Might!"

The video stopped there and the eyepatched man was sweating in fear and he was surprised.

"This keeps getting uploaded and taken down online, like a game of cat and mouse. Both sides have realized... Especially the last part... This guy's way of life is infectious. From scoundrels with countless previous convictions to felons on the run, all the major players... including me, of course... Not many people have noticed yet, but the evil that was scattered, hiding deep and quiet in places where no one could see them, has now hit by a single fever... To the organization Hero Killer: Stain is part of... They have started heading to the League of Villains."

New villains appeared in many different dark places as they headed to where Shigaraki is along with a certain woman. Cheetah. She had been searching for Y/N for a fight and revenge until she found her in one of the Stain's video and smirked. She even heard about the group called League of Villains and she decided to assemble with them as her ally and liked the idea in order for her to find Y/N. Cheetah took a walk after she killed the man who was sexually harrassing her and left a claw mark with blood on the wall.

As for Dr. Wu, he was excited to hear about the villains coming to Shigaraki and was currently working on the DNA as he had finally found the last piece which is the tooth of Indominus Rex. It was supposed to be destroyed after T-Rex squashed it and it looks like there is only one left. He was planning to re-create the Indominus Rex, but much more stronger and faster and it would go for kill only. He smirked deviously as he took out the small bottle of the blood of Y/N's he had experimented on her before she escaped and poured it in the measure cup as he was working.

Another elsewhere, Owen, Claire, and Maisie are traveling in the airplane toward Japan. Owen found where Blue is along with the other dinosaurs that had run off. They are also searching for the girl named Y/N L/N. He had found out that the Indoraptor was actually her and had to find her before they do or else it's too late, also he also wanted to apologize for not saving her as well as Maisie for not knowing she's a human in that dinosaur form. He promise he will protect her along with Blue no matter what.
