No one's POV

Three days had passed since the start of Sora's Hero internship at the Yellow Gale Agency. Since he had obtained the katana and learned his aura control, he'd been training all day long. During the sun rise until sun down he would follow Naruto on the field trying to catch up to him. Whether Sora could outrun Naruto in catching Villain first was a grueling task.

During the night after dinner, Sora would ask some of his senior like Konohamaru and Rock Lee to spar with him hoping it would train Sora in his aura to the point it becomes second nature. While also during midnight, while the rest of the Pro Heroes were asleep or already went home, Sora would be on the training ground training his sword skill. Though some of the Heroes were against it when Sora uses a katana like Sasuke, since a Hero is supposed to protect life not take one. Sora assures them that he would not take life unless it was necessary.

After swinging his sword for the 1000th time, Sora finally stopped to rest. It was then Naruto walked in to the training ground.

Naruto: Still training hard I see. But that's it for today.

Sora: Huh? The sun hasn't even set yet. Is there another training regimen?

Naruto: Let's have a family dinner with Hinata and Hima.

Sora: ?!

Sora was taken aback by Naruto's proposal. Naruto had never suggested something like hanging out as a family. He usually too focused on work so much that he'd sometimes come home late at night or even not come home at all. So for him to suddenly suggested that they had some family dinner together, it was so out of character for him that Sora found himself momentarily speechless. Seeing Sora's expression, Naruto smile wryly.

Naruto: I've been thinking what you say as well, you know. And you were right. Let's forget about work for now and just hang out.

Naruto say awkwardly. Even he knew that he was doing things out of character. But he knew he needed to change or he will regret it for the rest of his life. And not only that, the current crime rate in the Shinjuku area where the Yellow Gale Agency is currently low. So they would have more free time to get off work.

Sora(mind): We'll be passing Hosu city. Is Iida doing okay? I've been trying to get in touch with him, but he hasn't responded to my messages at all. He usually responded within three minutes after reading messages.

During their way back home towards Minato city, Sora and Naruto were riding a bullet train, and they were gonna pass Hosu city soon. The sun is almost down, so Sora knew that the Hero Killer would make his move soon. Since all the news he'd read about the Hero Killer is most of his victims were find in an isolated area and mostly attacked during the night. Suddenly...

Citizen 1: Hey look! That building just exploded!

Sora and Naruto: ?!

That immediately caught both Sora and Naruto's attention.

Naruto: A building just explode?

Sora: Is it a building that caught on fire?

Then suddenly one of the train passengers comments that a building has exploded and one of the Nomu's breaks into the train, having overpowered a Pro-Hero.

Sora: A Nomu!

Naruto: Stand down, Sora!

Sora: Dad!

Naruto leaps into action and tackles the Nomu out of the train and into the city. Sora cries out his father's name just as he notices several areas of the city going up in flames.

Sora: Wh-What is that...? What's going on...?!

The train immediately went on an abrupt halt. Seeing this, Sora immediately exits the train and searches Hosu City for Naruto. He ponders whether this Nomu is related to the other, and uses his newly mastered abilities to navigate the city.

Sora: Tempest; Zephyrus!

Sora(mind): Why is there a Nomu here? Judging by its appearance, it must be a different species than the one All Might fought in the USJ. Since Dad is able to handle it, it must be more to a speed type Nomu rather than strength.

Sora took note of the situation. The square at the western city of Hosu that would normally be overflowing with stalls and customers was currently surging with a stream of revenants of Nomu. On the other hand...

The city's reaction is also swift. Police and Heroes were already gathering at the road leading to the west city and assuming battle formations. Sora could see his Dad  already taking command and taking down multiple Nomu with his Shadow Clones and Chakra Flames. They were forming an improvised defense line to prevent the Nomu from invading further; it was possible that personnel had been placed at the west in advance as a precaution. During his run, a sudden explosion was heard and he could heard people screaming from the east.

Sora(mind): East...?! The explosion was delayed compare to that in the west...? This is clearly plan...! Since the explosion was delayed compare to the west, than the east will have the least Hero available since they're probably be fighting in the west! So I should go east...!

Sora turned on the spot and looked to the east. There, swarms of human-like Nomu that Sora had never seen before, and they were appearing from the alleyway right before the east city. The police and civilians noticed the surprise attack and send out a distress signal in a hurry, but a new human-like Nomu appeared, letting out a ferocious roar.

Nomu: MROOOOOH!

The Nomu like revenant used its tremendous physical abilities to take a running leap, soaring over the heads of civilians to arrive at the east city first. It then started running amok, smashing buildings into pieces.

Sora(mind): What kind of Nomu is that?! It looks like a human-type monster?!

Nomu 1: Guheehee!

Nomu 2: Buhee! Buhee!

Sora(mind):...That's a lot. How many are there in total?

Roughly estimating, Sora would guess the number of revenant to the east and west easily surpassed one hundred. And they were still appearing from the alleyway. The situation was gradually becoming worse. With no other choices, Sora immediately went to the east. There were only a few police officers and less Hero since most of them were probably in the west city. The situation was hopeless. They wouldn't even be able to last minutes like this.

Nomu: Geeeehhk?!

Suddenly, a strong gale blew from the diagonally left to the side, and all of the monsters right before the civilians eyes were easily blown away.

Child: Eh...?

The litlle girl found herself gazing in amazement. The other police were also dumbfounded. Just then, Sora landed lightly right in front of the little girl.

Sora: Allow me to assist until the Pro Heroes arrive.

Child: A-A Hero...?

The little girl stammered immediately.

Police officer: Who are you?

The police officer ran towards Sora and asked for his identification since it was clear that Sora was just a child.

Sora: I'm a Hero who's currently doing internship with the Number 3 Hero, Yellow Gale. I've been tasked with helping any civilians that I've come across. So until the other Pro Heroes arrive, allow me to give you a helping hand.

Police officer: T-Thank you very much!

Sora's answer filled police officers with relief, though they still had some skepticism about Sora's identity since no matter how you look at it, Sora is still a boy in his teen, still they thanked him from the bottom of her heart.

Sora: Now, let's reduce the number of monsters as much as possible before the reinforcements arrive. May I take the frontline?

Sora asked as he braced his sword and faced the Nomu, who seemed to be wary of Sora and had frozen in place.

Police: Y-Yes, please do.

The police nodded.

Sora: Then, if everyone here could handle the Nomu Revenant that makes it to the street.

With those words, Sora calmly closed his distance with the Nomu. Sending his aura into the sword in his hand, he created a large gale of wind and fired it at the monsters.

Nomu: Guhee?!

Dozens of the Nomu before him were pushed back to the building, easily blown away. No sooner had he done that, Sora was charging into the group of Nomu revenany, initiating close-quarters-combat.

Police officer: J-Just what is that boy?

The police officer muttered in a daze at the tremendous sight of Sora's combat prowess, frozen in their awe.

Child: Amazing... that's really amazing!

The little girl that was saved, her mother, the civilians, and the police officers were captivated by Sora's fighting as they stood at the middle of the east city to the center of the square. Sora was leaping around the square, taking on the crowd of Nomu-revenant alone.

Nomu 1: Gyah?!

Nomu 2: Buhee?!

The little Nomus were being cut down as soon as they approached Sora; the speed with which he dealt with them was even faster than that of yesterday when he couldn't even keep up with Naruto.

Sora(mind): It's strange...! Their movements feels like a downgraded version of the one that fought against All Might...! No it's still not the same as the one that Dad fought...! Is it even a Nomu at all...?

Civilians 1: Hey, isn't that the boy who won the U.A. Sports Festival...?

Civilians 2: Your right! I recognize that face...!

Civilians 3: Way to go, Hero!

Most of the Nomus in the square were attacking Sora, making him a one-man army. He turned the tables on every Nomus that attacked, making the creatures in the square meet their end with swiftness. Every so often Nomus would sneak past him towards the road, but those were easy for the Police to deal with.

Police 1: Is our help even needed...?

Police 2: And to think he's still a child...?

The police officers were in awe. Even at this moment, Sora was slaughtering the approaching Nomu. His movements were like a nimble acrobat, seeming almost beautiful.

Child: He's awesome! You're awesome big brother...!

Before everyone else knew it, the one hundred army of Nomu revenant was left with only two left.

Nomu: ?!

The other two froze in shock. Sora took that opportunity to close in on one of them, once more thrusting his sword through its heart with precision. Then, once he pulled his sword out, He turned back and landed a knee-kick into the abdomen of the other one approaching from behind.

Nomu: Vuh...!

The Nomu revenant easily lifted into the air. Sora kicked off the ground and pursued its body in an instant, finishing it off in a similar single blow by stabbing it through the heart. All that was left was the one Sora punched away first.

Nomu: Vurrgh...

Sora closed in on it instantly as it staggered back to its feet, and once again, stabbed it through the heart like the others to finish it off. He withdrew his sword.

Sora:...Phew.

With the mental fatigue kicking in, he sighed quietly.

Mother:...T-Thank you so much!

The mother that had been watching Sora's fight in a daze snapped back to her senses after a pause and thanked him.

Sora:...No, I'm just glad to see you aren't hurt. Can you stand?

Sora asked, approaching the mother and offering his hand.

Mother: Yes, I'll manage...

The mother grabbed Sora's hand and hesitantly stood up.

Child: T-Thank you so much, mister! Mom, are you all right?

The little girl asked, running over to support her mother.

Mother: I'm fine.

The mother replied, giving an awkward smile to reassure her daughter.

Police 1: We thank you for your assistance! As a police officer, we thank you... and I'll be sure to report this to Yellow Gale about what you've done...!

Sora: Oh... Not at all...! I'm just glad I was able to help...!

Police 2: No...! As the adults here, we are ashamed for letting ourselves be saved by a child who's still in school no less. So please let us thank you for your service...!

The police officers all bowed their heads in shamed, but at the same time they were grateful and had eyes full of respect for Sora's ability.

Sora: Um... very well, I'll accept your gratitude. So please raised your head. And it seems the Pro Heroes are already arriving on the scene. Since I'm still an intern, is it alright for me to let you clean up with the rest?

Police: Yes of course. If anything, let us be the one to do it. I'll be sure to tell the police chief and Yellow Gale's Agency at your exploits.

Sora: Yes. Very well.

Sora smile and left the east city. He was about to went to the west where his Dad should be currently fighting where he suddenly get a notification on his phone from Izuku, which was his location information, confusing him.

Sora: He share his location...? Why...?

Looking at the location, Sora realizes that it was on an alleyway near the east streets and not only that it was at Hosu city. The location is not that far from him, and Sora's eyes widened looking in the direction.

Sora: Don't tell me...

(Elsewhere)

Watching from a nearby building, Tomura praises the Nomus for the chaos they have created. His master loaned him the Nomu's and revenant so that he could kill Stain, only because Tomura doesn't like him. But he was in complete shock when he saw Sora appearing and destroyed his revenant with complete ease.

Tomura: What the heck is that child...? He continue to appear and ruined my plan like this.

Kurogiri asks if Tomura will join, but Tomura replies that he won't due to his injury.

Kurogiri: Should we assume that he's the one that person wanted...?

Tomura: Master would never wanted a small child...? But we should probably report him.

(Elsewhere)

During Izuku's search for Tenya, he surmises that the League of Villains and Stain must be connected somehow. Most of Stain's attacks on heroes have been in unpopulated areas. Using that information, Izuku decides to search all the alleyways close to Manual's Hero Office and eventually finds Stain just as he's about to finish Tenya.

Izuku acts swiftly, using One For All's power to deliver a powerful smash to save his friend. He tells Tenya they need to move to a more open area so pro heroes can support them, but the former reveals he's unable to move ever since Stain cut him. Izuku surmises that perhaps Stain's Quirk activates by cutting his opponents, and then realizes that Native has been injured as well. Unable to carry both of them away, Izuku bravely decides to protect them both by holding off the hero killer on his own.

Stain warns Izuku that it's his duty to kill Tenya, and if the young man gets in his way that the weaker of the two powers will be culled. Intimidated, Izuku realizes that Stain is a totally different breed of villain than those at the U.S.J. and decides to send out his location information. Tenya pleads for Izuku not to get involved because it has nothing to do with him but he refuses, re-stating words he had once heard from All Might: That the essence of being a hero is meddling where they don't have to. Stain takes notice of Izuku's words and recognizes him from the photo Tomura showed him earlier.

Their duel begins as Izuku uses Full Cowl to swiftly close the distance between him and Stain, effectively negating the advantage of the former's longer reach. The hero killer tries to slash Izuku with a knife using his free hand, but the young hero slides through his legs. Stain moves to counter by swiping his katana behind him, but Izuku promptly evades by jumping above Stain. Then, Izuku uses a 5% Detroit Smash and delivers a powerful blow to his opponents head. Surprised by Izuku's feat, Tenya compares his movement's to Katsuki's. Unphased by Izuku's attack, Stain licks the blood from his knife and immobilizes him. Izuku realizes that Stain managed to graze him, and that blood is the key to activating his Quirk. Stain is impressed with Izuku's skill and conviction, and decides that Izuku is worth allowing to live because he is different from Tenya and Native.

Stain: People like you are a dime a dozen, but you're worth letting live. You're different from these guys.

Izuku: Damn it...

As prepares to take the lives of his next two victims, Izuku would scream at him.

Izuku: STOP IT!!!

The Hero Killer prepares to take the lives of his next two victims, but is abruptly forced back when a stream of fire comes at him.

Stain: Another one. There are a lot of people standing in my way today.

Shoto: Midoriya. You need to give me more details in times like this. You made me late.

Shoto appears suddenly, scolding Izuku for not explaining the urgency of the situation because he could have gotten there sooner. And to Izuku's surprise, he was using his flames.

Stain: ?!

Stain's eyes widened, as he once again jumped out of the way barely dodging a second attack which was a wind slash attack coming from a sword. The person then stood next to Shoto revealing to be Sora in his Tempest; Zephyrus.

Sora: The fact that everyone is still alive, I say we're right on time.

Seeing both Sora and Shoto, Izuku and Tenya both looked surprised.

Tenya: Todoroki... Uzumaki... You both too...?

Izuku: Why are you both here...? And Todoroki... you're using your left side...

Sora: Why are we here...? That's our line. It took me a second to figure out what you meant.

Shoto: Same here. Especially since you sent just your location information. You're not really one to send that for no reason.

Shoto sends a wave of ice at Stain to repel the villain while securing his injured allies.

Shoto: You meant that you were in trouble and to call for help, right?

Sora: Honestly, you just love to get yourself in trouble!

As Stain was up in the air avoiding the ice attacked, Sora rushes in with his sword in play and let out an avalanche strike. Then as Stain block the attack upwards, Sora sent a flurry of thrust towards him. Stain however counter them with his own flurry of strikes. It was like two people dancing on stage that took the breath of the spectators.

Stain(mind): This kid is fast...! He must be the other boy from the picture Shigaraki showed me.

Izuku: Sora... Since when he could use a sword like that...?

Gaining some distances from Stain, Sora jumped back to Shoto's side.

Shoto: Don't worry. The Prose will also get here in a few minutes.

Sora: This is just like the information about him implies. We won't let you kill these guys, Hero Killer.

As they continues to push Stain back, Shoto using both his ice and fire, and Sora with his Wind and sword skills, Sora warns the hero killer that they will not allow him to kill his friends.

Izuku: Sora, Todoroki, you can't let this guy see your blood! I think he controls his opponent's actions by ingesting their blood orally. That's how he got all of us!

Sora: Ingesting our Blood?

Shoto: He sucks blood to keep people from moving.

Sora: That's why he uses blades, huh?

Shoto: Then we'll keep my distance and-

Without warning, Stain would throw two throwing knifes towards Sora and Shoto. Sora would deflect the blade with his sword, however Shoto was cut in on cheek, as Stain rushed him.

Stain: You have good friends, Ingenium!

As Stain went to slash Shoto, he was blocked by a sword. Sora stepped forward and engaged Stain with his own sword. Their speed was equal. Their technique was off the roof, however it was clear Stain had the upper hand when it comes to using swords, since he'd been using them for years, while Sora had just recently learned how to wield them. Sora's long katana clashes with Stain's multiple short swords and knifes.

Sora and Stain(mind): Our speed is equal!

Sora continued to clash with Stain, he had quick lightning reflexes equal to that of Sora, Stain parries one of Sora's strike, surprising him. Countering, Stain was about to land a slash on Sora's face, only to be blocked by a chunk of ice.

Howbeit he tossed his katana in the air at the same time to distract his foe. Abstracted, Shoto nearly allows Stain to lick the blood from his face but he was repels by Sora's quick reaction to throw his sword in between Stain and Shoto's face.

Sora(mind): That was so close.

Shoto counter attacks with waves of ice, but Stain grabs his katana to defend himself, Sora too grabbed his katana and he channels wind on it and send a strong gale towards Stain. Getting hit by the strong wind, he stepped and commends Sora and Shoto for their strength.

Stain(mind): These two are strong...

Tenya: Why are you three... Why... Please stop! I've inherited my brother's name. I have to do it... That guy's mine...!

Tenya pleads for Sora and Shoto to stop because he's inherited Ingenium's name, and only he should stop the hero killer.

Shoto: You inherited it? That's strange.

Withal, Shoto replies that Ingenium never had the look of vengeance plastered on his face.

Shoto: The Ingenium I saw before didn't have that look on his face, though. You've got a lot going on behind the scenes in your family, too, huh?

He creates a giant wall of ice, but Stain slashes through it and tells Shoto that it's foolish to block his own view when his opponent is faster than him.

Stain: To block your own view against an opponent faster then you... What a foolish plan.

Sora: That's why I'm here!

Sora was there to cover Shoto's lack of speed. And combining with his quick reflexes and swordsmanship alongside Shoto's Fire and Ice Quirk, the two of them managed to keep Stain at bay. But still, the two of them still couldn't get a decisive victory.

Sora: Iida... I too had a lot of going on behind with my own family! So if I had to say something then... Don't let your emotions clouded you into becoming the person you wanted to be!

Tenya: ?!

Sora said blocking the throwing knife that was aimed at Shoto's left side. Sora's words made Tenya's face appear more shock than ever. What he wanted to be? He wanted to be a Hero that had inherited his brother Ingenium name? But has he really been able to do that? During his internship, has he really be the Ingenium that held his hand towards the people he needed to? Tenya's mind spiral out of control.

Meanwhile, the fights continue by Sora once again deflecting a knife that was thrown towards Shoto, however by doing so, he was opened for an attacked. Since Sora was in front of Shoto's line of fire, Shoto will be unable to act.

Stain: You're both pretty good, too!

Just before Stain's sword was about to thrust into Sora's chest, suddenly Izuku would jump up shroud on a green aura, grabbing Stain, and slamming him into the wall, surprising both Sora and Shoto.

Sora: Izuku!

Izuku: I can move normally for some reason now!

Shoto: A time limit?

Native: No... That kid should've been the last one he got. I still can't move yet...

Sora rushes to Izuku's side and send a strong gale towards Stain while also grabbing Izuku before jumping back towards Shoto who send a huge chunk of ice.

Izuku: He takes in a person's blood to keep them from moving. Since I got free first... I can think of three possible reasons. It could be less effective with more people, the amount of ingested could affect how long it works, or there could be a difference in effectiveness based on a person's blood type!

Native: Blood type? Mine is B...

Iida: I'm type A...

Izuku comes to the conclusion that Stain's power's effectiveness varies depending on blood type, to which the Hero Killer confirms.

Stain: Blood type? That's correct.

Izuku: I can't really do anything just by knowing his Quirk, though...

Shoto: I wanted to hurry and carry those two out of here, but he can react so fast to my ice and fire. He even could react with Uzumaki's ferocious attack while also defending against my attack. I think our best option is to hold on by avoiding close combat until the pros get here. And Uzumaki, why aren't you summoning your clones?

Shoto was perplexed by the signs of Sora not summoning his clones not even once during this fight. If he had summoned them, this fight would have been advantageous for them with quantity. But still Sora refuses.

Sora: Summoning clones drains a lot of my stamina. If I summoned even one clone right now, I'll give away my advantage in speed against an opponent like Hero Killer.

Unlike Naruto his Father, Sora doesn't have an inexhaustible amount of energy. His clones summoning is limited. That was why he had been training in reserving his energy more often in the internship. Yes summoning clones would make them advantageous. But unlike him, his clones only posses half of his original strength. And summoning clones drain more stamina in Sora's body, because the fatigue gain from each clone will by accumulated into his own body.  So that's why...

Shoto: I see...

Shoto nodded in understanding at Sora's explanation.

Izuku: Todoroki, you've already shed too much blood. Sora and I will distract him, so you support us from behind!

Shoto: That's a pretty big risk, but yeah...

Sora: The three of us will protect them...

Izuku resolves to distract Stain along with Sora while Shoto supports him from behind since the former has already shed so much blood. Although reluctant to the risk, Shoto agrees to protect Tenya and Native together with Sora and Izuku.

Stain: Three against one, huh? It won't be easy.

Suddenly green energy of electricity surrounded Izuku. Sora looked at him confusingly thinking what kind of new techniques did Izuku learned on his Internship.

Sora(mind): That's new... He's keeping up with my Tempest; Zephyrus! And those are some of my moves alongside Sarada's speed and Katsu's ferocity!

Shoto on the other hand recalls worrying about Tenya ever since Ingenium was attacked because he recognizes someone who's acting on pent-up resentment. Shoto also knows too well how that negativity can cloud someone's judgment.

Shoto(mind): Iida... I've been worried about you since your older brother was attacked, because I know all to well the face of someone who would act on pent up resentment. I also know just how narrow the field of vision can get for someone like that...

Sora and Izuku continue to rush down Stain, Sora would sent a slash with his sword and Izuku went to punch him, but Stain would dodge Izuku's punch and counter Sora's sword strike with his own sword. Shoto would send another ice wave towards Stain, forcing him to jump back, along with dodging a blast of fire.

Shoto(mind): Everything was so simple! But even thought it was simple, I didn't see it.

Shoto recollects visiting his mother, and how visiting her cleared up his own perception. He told her everything that happened and so she apologized and forgave Shoto for not visiting her for a long time. She also encourages him to move forward in his life without anything holding him back, as that would be her salvation.

That's why he decided to intern with Endeavor's agency, not because he has forgiven his father, but because he wishes to learn from the experience of the number two hero. Shoto realizes that everything could have been simpler for him, but never noticed until Sora and Izuku opened his eyes with just a few words.

Izuku: It's your power, isn't it?!

Sora: So prove it to me right now! Prove it to everybody that is watching right now, that you have your own goal! That you are not just the son of the Number 2 Hero, but you are Shoto Todoroki!

Shoto(mind): Just because of those words! Those words!

With the intensity increasing, Stain heightens his strength and overpowers Izuku. He cuts open his leg and licks the blood to paralyze him.

Shoto: Uzumaki...! Midoriya...!

Tenya: Please stop... I'm already...

Sora supports him, but Tenya again pleads for them to stop.

Shoto: If you want us to stop, then stand up! The only words I can say to you are; Look properly at what you want to be!

Shoto rejects his plea, tells Tenya to stand up and look properly at who he wants to become. Stain slashes through a wall of ice and goes to attack Shoto, who responds by releasing his fire.

Sora: Keep moving forward! Onward! Onto the path you have set for yourself, Iida!

Sora said sending a Rasengan at Stain whom dodged the attack. Stain went to slash Sora but was blocked by a Fire from Shoto's attack. After Sora tries to save Tenya like Izuku had done for him, Tenya reflects shamefully on himself and starts to move his hand.

Tenya: Uzumaki... Todoroki...

Shoto encourages Tenya to never forget the man who he wants to become, and Sora encourages him to continue moving forward towards what kind of Hero he wanted to be. Ashamed to have caused his friend's injuries, Tenya recalls memories of years ago when Tensei became the motivation for him to become a Hero.

Izuku: Sora! To your right!

Sora Guh...!

As Sora would rush Stain from the side, he coated his katana with Wind.

Sora: Gale-!

Stain: Your speed is impressive! But your technique still needs some refinement!

Sora: Gah!

Without warning Stain would quickly react to Sora's slash before kicking him in the face, knocking him back, as he then rushed Shoto. Shoto continues to try and force Hero Killer: Stain back, prompting the villain to comment that the young man relies too heavily on his Quirk in combat.

Stain: Ice and Flames! No one's ever told you? You're too focused on your Quirk. You're being careless!

Tenya comes to the realization that Stain was correct in stating that he isn't a true hero and decides that he must stand up if he wants to truly become a aspiring hero like Tensei, Sora, Izuku and Shoto. Just before Stain slashes Shoto with his Katana, Tenya's Recipro Burst enhanced kick breaks it.

Tenya: Recipro... Burst!

Stain(mind): Damn it...it stopped working, huh? And he's fast too!

Sora and Izuku: Iida!

Shoto: You got free. That Quirk isn't as great as I thought.

Tenya: Todoroki... Uzumaki... Midoriya, this has nothing to do with you three, and I apologize...

Sora: Seriously!

Izuku: You're saying that again?

Tenya: That's why I can't allow you three to bleed more than this!

Stain: It's no use trying to be reformed for appearance's sake. A person's essence does not change so easily. You will never be anything but a fake who prioritize his own selfish desires. You are a cancer to society that warps the idea of "Heroes. "Someone must set you straight.

Tenya apologizes for getting his friends involved, but Stain refutes this and states that Tenya will never reform into a true hero.

Shoto: You're an anachronistic fundamentalist. Iida, don't listen to the logic of a murderer.

Tenya: No, he's right... I have no right to call myself a Hero... Even so, I cannot give in. If I give in, then Ingenium will die...!

Shoto tells Tenya not to listen to the villain's words, but Tenya agrees that he isn't a true hero. Nevertheless, Tenya believes he can't give up or else the name of Ingenium will die.

Stain: Out of the question.

Stain attacks again, but Shoto forces him back using his fire. Native urges Shoto to flee, but he refuses and says that Stain won't give him an opening. Although Shoto realizes that Stain's Quirk isn't especially effective in a battle against multiple opponents, he notes that Stain has only gotten more tenacious in his attempts to kill his targets.

As Stain proceeded to jump around Shoto, who was using his ice, but Stain started to slash it to pieces.

Shoto(mind): There's the uncertain element of blood type, and he needs to get in close for it to work. On top of that, it doesn't last very long... Looking at just his Quirk, he's not especially powerful. Taking on multiple opponents alone must be hard for him to deal with. He's gotten desperate trying to kill Iida and this person before the pros come. He's got crazy tenacity...

As Tenya attempted to go help him, his engines would start to smoke and stall.

Tenya(mind): Oh no, Recipro's done. Did I break the radiator during that my kick earlier?

Tenya: Todoroki, can you regulate temperature?

Tenya intercepts one of Stain's throwing knives targeting Shoto, then asks his classmate to freeze his radiators.

Shoto: I'm not used to it with my left yet, Why?

Stain pins down Tenya using another knife. At the same Izuku regains his mobility. Shoto does as Tenya asks, allowing him to unveil his new special move: Recipro Extend.

Sora and Shoto: Go!

Tenya and Izuku then rush Stain by using their Quirks to scale the alleyway and strike the Hero Killer simultaneously.

Izuku and Tenya: That's all I need right now!

Shoto: They stopped him!

Sora: No! He's not down yet!

Stain reels back from the students' teamwork and tries to slash Tenya. Tenya evades and kicks the villain higher into the air, where Sora finally connects with his Rasengan.

Sora: Rasengan!

Shoto then freezes a path for Sora, Izuku and Tenya to fall down while restraining Stain at the same time. After all the fighting, the four students notice that Stain has finally been defeated.

Sora: He probably knocked out after all that...

Shoto: Then let's restrain him and get out to the street. Is there anything to tie him up with?

Izuku: Just in case, let's take all his weapons off him.

Shoto: Good idea.

Sora: Yeah. That would be wise.

Shoto restrains the defeated Hero Killer using rope that he found in a trash bin while Native carries an injured Izuku out to the street.

Sora: Sir Native, can you move?

Native: Yeah, I'm okay now.

Izuku: U-Um..

Native: You hurt your legs, right? Let me do this at least.

Izuku: T-Thank you very much...

Native: That's my line.

Shoto: You can find anything at a trash collection site.

Tenya: Todoroki, I'll pull it!

Sora: Fighting 4 on 1 with the guy making mistakes himself, we still barely won. He probably flustered and forgot about Izuku's recovery time. And he wasn't able to deal with Iida's last Reciproburst and my Rasengan's attack.

Native: Now, let's quickly get him to the police—

???: Wha...? Why are you here?

Hearing the voice, Sora and the rest saw an extremely short, elderly man with heavy wrinkles and a scrawny build. He has a light complexion and brown eyes. His hair is grey and spiky, styled short with some bangs hanging forward and a trimmed beard.

His hero costume consists of a full-body monochrome suit along with a yellow cape, a belt with the letter "G" on it, very thick yellow gloves and boots, and a dark domino mask which resembles two diamonds.

Izuku: Gran Torino!

Without warning, the Hero named Gran Torino sped over and kicked Izuku in the face.

Gran Torino: I thought I told you to stay seated on the bullet train!

Shoto: Who's that?

Izuku: The Hero I'm interning with, Gran Torino. But why?

Gran Torino: 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 okay.

Izuku: Gran Torino, I'm sorry..

Gran Torino meets them there and berates Izuku for leaving the train against his orders. The other Pros arrive to call an ambulance for the injured and the police to arrest the Hero Killer.

Tenya: You three...

Tenya would then bow his head to them with tears in his eyes.

Tenya: You were injured because of me. I am truly sorry. I couldn't...see anything...through my anger...

Izuku: I'm sorry too. Even though you were feeling so cornered, I didn't notice at all. Even though we're friends

Sora: If that's the case, then some part of this goes to my fault, I'm the Class Rep of the class and yet I didn't see just how my classmate was in trouble. So some of the fault befalls to me too.

Shoto: Pull yourself together.

Tenya takes a moment to apologize to his friends for getting them mixed up in the fight. Suddenly, Gran Torino noticed something.

Gran Torino: Get down!

Suddenly, the last Nomu swoops down from the sky and snares Izuku. Before it gets too far away, Stain recovers and uses his Quirk to stop it. He saves Izuku by grabbing him and stabbing Nomu's brain.

Stain: Should all be purged...This society overgrown with fake heroes... and the criminals who wave their powers around idly...

In spite of being heavily injured, Stain states that the "fake" pro heroes and the pathetic criminals in society must be purged to create a more just society.

Stain: This is all... to create a more just society...

Everyone is taken back by his actions and Endeavor arrives. Stain is enraged by Endeavor's arrival and challenges all the heroes to try and defeat him in battle.

Stain: Endeavor... Yellow Gale...

Upon seeing Stain, Endeavor's flames would begin to flare up, and Naruto would transform into his Chakra Armor.

Endeavor: Hero Killer!

Naruto: Stop it! You can't beat us both!

Gran Torino: Wait, Todoroki! Uzumaki!

The bandages over his face fall off and Stain releases a malicious aura that paralyzes everyone with fear, making even both Yellow Gale and Endeavor step back.

Stain: Fakers...I must make things right...Someone must be dyed in blood...I must take back what it mean to be a hero! Come! Try and get me, you fakes! The only one I'll let kill me is the true hero....

His aura grew more suffocating that all the Heroes all brace for what nightmare to come.

Stain: ALL MIGHT!!!!!!!!!!

The Hero Killer prepares to attack, but his perforated lungs cause him to lose consciousness.

Gran Torino: He's unconscious...

Even though he was incapable of fighting, Stain was the only one left standing to face his opponent.
