Aftermath

Shouta wants nothing more but to go home and sleep. Unfortunately, he still have to interview his students about their sides of the battle. Thankfully, he only has one student left.

Kamihara Kakashi

The boy was a headache, charging into a battle and taking the leader on. The fact that he was close to defeating the villain was one thing, that doesn't stop Shouta from wanting to strangle him though.

Right now, Kamihara was staring at him with a bored expression. He had removed most of his armor, including his sword.

Shouta wished he wouldn't have to deal with this. Kamihara was not the type to give straight answers. Nedzu and All Might were watching through the cameras, so atleast he has people to to deal with the headache as well.

"Kamihara, your side of the battle. And make sure you give straight answers."

"Maa, when we got to the USJ, I have this feeling like something is off." Kamihara said, actually giving him what he wants. The fact that he had a bad feeling talks a lot about Kamihara's instincts. "When the villains showed up, I was about to unsheath my sword when I got sucked into a portal."

Shouta hummed, gesturing for Kamihara to continue. The sooner they finish, the sooner he can go home. That, or go back to Recovery Girl's clinic.

"I ended up in the Shipwreck zone where Midoriya-kun and Tsuyu-chan were as well. There were villains waiting for us bellow. I told them I'll take care of it and proceeded to electrecute the villains. We then made are way to the center."

So far, his statement corresponds to both Midoriya and Asui. The thing was though, the other two gave a more descriptive retelling.

Kamihara had specifically avoided mentioning how he managed to stand upside down the ship and walk on water. A good tactic to keep your abilities a secret from your enemies, but annoying when making a report.

"I was ahead of them, and I saw you struggling against what I assumed had been the leader. I gestured for the other two to stay back and made my way to help you."

Assumed? He knew that Shigaraki was the leader.

"I pushed him away from you. He then ordered the corpse he called a Nomu to attack me and-"

"What do you mean corpse?" Shouta snapped. This kid knew more than the heroes, Shouta had heared him talked to the leader. The problem was, he can't hear what they were saying. It had been muffled by the ongoing fights in the background.

"Maa, exactly as I said. The Nomu was a corpse, it doesn't have a heartbeat."

That was a rather terrifying thought. He had been fighting a corpse the whole time. 

"I pulled out a seal, and slammed it at the Nomu. I proceed to seal it."

"Seal?" Shouta asked, wondering what that is.

"Hmm, seal." Kamihara proceeded to pull out the paper he had used earlier. Now in front of him, Shouta can see strange patterns and kanji written on it.

"The Nomu's inside it."

Wait, what?

"I use seals to hold objects. Some seals, the more difficult ones, can seal even those that are alive or reanimated."

That is a scary ability. How does he even knew that it works on those that are alive or, Kami forbids, reanimated? "

How do make one?"

"Maa, I just need a piece of paper and ink. I also need to apply my quirk in it. I can unseal the Nomu if you want."

His quirk? What exactly is the kid's quirk?

"You can unseal this..Nomu in a safer area. Preferably a place with lots of pro heroes including All Might later." Shouta said, watching Kamihara nod before tucking the seal away.

"I then fought against the leader with the fake name Shigaraki Tomura."

So he caught on the fact Shigaraki was using an alias. What else did Kamihara learned?

"I got him to admit the Nomu was created."

It made sense considering the Nomu is a corpse.

"He said it was made to defeat All Might."

And that was information they didn't know. Shouta was right, Kamihara had vital information.

But villains coming to defeat All Might and being so sure? Something was off.

"I also feel like there is a secondary purpose."

"Go on."

"They weren't just there to defeat All Might, they also came to tarnished the reputation of UA. The attack was on campus with students, if there had been more gravely injured people or even death, the villains could make it look like UA is unsuitable as a hero school. The fact that UA is independent from many outside sectors, including the HPSC, would make people unsure if UA is fit to remain independent completely."

Aah, he managed to dissect a secondary purpose with strong points. Kamihara truely is a genius.

"Back to the fight."

"Hmm, I can't get any info out of Shigaraki after that. Deciding he was to valuable to let go, I managed to stun him. I was about to knock him out, when All Might arrived. I was distracted at his arrival, it was enough for Shigaraki to regain himself. He called someone he called Kurogiri to warped them away, and he escaped." Kamihara sighed.

Shouta could see in his mind quite clearly that All Might, Toshinori, must be feeling guilty at what they heard. Kamihara had been so close to capture the leader for more information, only to get distracted and have him escaped. If Toshinori had just arrived a moment later, they would have a villain leader in their custody.

"Any other info?"

"None."

"Very well. Do you need theraphy?" It was a suggestion Nedzu had came up with, a way to help the coming trauma. Iida and Yaoyarozu had agreed immediately, while some headstrong atudents who obviously needed it had to be forced.

"Pass."

Shouta sighed, he should have seen this coming. Then again, Kamihara acts like he had been through worse. That was worrying.

"Can I go now?"

Shouta stayed quiet for a while, before a knock came from the door. To help the students go home safely, they had called their responsible adults. Some like Todoroki and Yaoyarozu had been picked up by someone else besides their parents.

The door opened, and Shouta wants to hit his head for not noticing. Of course ninja boy's father is the famed Ninja hero, Edgeshot. How he never noticed, he doesn't know.

"Aah, you called my adult." Kamihara said, slowly gathering his stuff.

"You have no class tomorrow." Shouta said tiredly. Atleast Edgeshot will be the one to deal with the rest of the headache that Kamihara would bring.


Waking up being kidnap was not how Shouto planned his day to start. Edgeshot's secret lovechild looked at him, before giving him his eye smile.

Yes, Shouto believed Kamihara is Edgeshot's son. Why? The evidence says so. Ninja hero in-training and ninja hero. Both have the same hair, both are ninjas, and both wear masks. Sure Kamihara's quirk is far from that of Edgeshot, but Shouto knows the truth. 

"Todoroki-san?"

Shouto snapped out of his theories to find himself being stared by Kaminari and Tokoyami, the latter being the one to call him. He was in a living room, judging by the comfy sofa he was sitting and the flat screen tv in front of him. Kamihara was nowhere to be find.

"He kidnapped you too?" Kaminari said in disbelief. "How did he even knew where you live?"

Good question. That reinforces his theory. After all, Edgeshot is known to be the sneakiest hero.

"Maa, sorry about kidnapping you all." Kamihara said, placing a tray of food in the table. "But I wanted us to spend the day training together. After all, I can't let my new students slack off."

Aah, that would makes sense. Shouto ignores the fact that he will still have to train even if Kamihara didn't kidnap him. Atleast this will let him know the others quirks. 

"Don't worry about your parents, Kaminari-kun. I left a note that says you lot will be spending time with me." Kamihara said, before looking at him. "And your sister was awake when I took you. She was fine with what I was doing."

So, Fuyumi knew and let Kamihara kidnap me. Then again, she'll be fine with it as long as I'm not near that man.

The doorbell rang as they finish their breakfast of ramen. Why Kamihara eats ramen for breakfast, they will never know. Kamihara was quick to answer, and by that, Shouto means he suddenly poof into smoke.

Kamihara walked in with another teen. He looks older than them, and seems rather nervous. Shouto wonders if he is related to Kamihara.

"Maa, meet your senior, my older student." Kamihara introduced, the boy was fidgeting next to them. "This is Amajiki Tamaki, he is a third year UA student."

Wait, what?


Kakashi gave his students an eye smile. All five of them were in his father's outside training area. His father would be mad at him if the inside training room got trashed again, he learned his lesson with Tamaki.

"Alright, today I will be teaching you to expand your quirks." The new three looked at him confused, Tamaki, whoever, groaned.

"Kaminari-kun, do you know how to used your electricity into lightning  bolts?"

That earned a confused and shocked look from Kaminari. Looks like he has more work to do.

"Very well then. I will help you with that."

"Tokoyami-kun, you will be sparring with Tamaki-kun. Once I'm done with Kaminari-kun, I will help you improve on your quirk."

Tokoyami nod in understanding, though he seems to not want to spar an older student.

"Todoroki-kun, do you know how to control your ice without touching it?"

The look in Todoroki's face was enough for him to know.

"You'll be working on controlling your ice from a distance. Try doing it with smaller blocks before making it bigger."


Denki frowned in frustration as he control his flow on electricity away from his brain to his hand instead. Kamihara is a great teacher. He had told him to focus on getting his electricity away from his brain, to prevent him from shortcircuiting, and towards his arm.

Electricity came to life on his hand. He was getting the hang on this. Denki looked at Kamihara, gaving him a large grin.

"You're doing good. Now, hold it for as long as you can."


Fumikage admits that his physical strength needs work. Amajiki-senpai was busy giving Kaminari pointers on shooting his electricity, while Todoroki was learning to make his ice more heat resistant. Kamihara, however, was keeping an eye on him as he punches and kicks the training dummy.

"Maa, you're not doing it right."

What?

"You're wasting too much energy on your hits, but your accuracy lacks. It doesn't matter how strong you are, if you don't hit in the right area, you will still lose."

Kamihara eyed Dark Shadow. "Try to use your quirk to stun your enemies. Use it to hold them, to get them off balance."


Shouto focused as he makes his ice. So close, he was so close. Suddenly, the ice cracked and broke. Shouto grit his teeth in frustration. The ice mirrors Kamihara told him to try making shouldn't be so difficult. What was he doing wrong?

"You're focusing too hard." Edgeshot's secret love child or number 1 fan said, Shouto had decided to make a new theory after seeing the amount of Edgeshot merch Kamihara has in his room, almost as if he read his mind. "Ice is smooth, just as it is harsh. It is cold, just as it is fragile. You need to be calm and collected, focus yet still alert."


Kakashi watched his students as they trained. They were progressing very well. Kaminari was shooting lightning at the targets, Todoroki was making more ice mirrors, and Tokoyami was sparring with Tamaki. 

Kakashi can't helped, as pride swelled in his chest. He had took Tamaki in at first to replaced his former students, but now, now he had seen their potential and trained them the best he could.

These four are my new students. Naruto, Sasuke, Sakura, Sai, if you are watching this, I know you will see what I see in this four. Tamaki, Tokoyami, Kaminari, Todoroki, I promised I'll train you to be just like Team 7 had been. To be the best heroes this world had ever seen. To become the legends of this world like my old team had been in ours.
