Eraser Head felt cold drops of sweat sliding down his skin. Out of all the villains he fought, All for One was the scariest. Even if that villain was far away, he could feel All for One's intense and choking pressure.
He was not alone in feeling it. All students knew who they were facing and some of them were probably scared. But the heroic spirit inside them didn't waver and made them strong. In a different circumstance, Eraser Head would be proud of them. That was why he wanted them to live on and when the disaster known as All for One goes away, there would still be heroes. And it was up to the adults to deal with that villain… or that was how it was supposed to go.
"Everyone! Be on guard!", Eraser Head shouted as he noticed something was flying towards them.
Or rather… something was being thrown at them. The object crashed to the ground and when Eraser Head, Midnight, and the students identified what it was, they went pale. It wasn't an object but instead, it was the hero named Hound Dog. His arms, fingers, legs, and neck were twisted in an abnormal way and there was a huge hole on his chest.
"W-W-What the hell?!", Minoru asked in fear when he saw Hound Dog.
That was what could happen to him and everyone. Momo closed her eyes and covered her mouth. Ibarra did a silent prayer. Tetsutetsu and Eijiro roared and hardened themselves.
"This is what could happen to you. While he's still not here, it's time to run", Eraser Head said without facing them.
Mineta Minoru immediately ran away, fear griping his heart. No one judged him for that. Everyone wanted to live and being a coward is okay. He just wanted to live.
"Everyone. I'm not asking you to fight with me. No matter where you are or what actions you take, you are a proud UA student. And even UA is destroyed, its legacy shall live. UA is not the place. It's the spirit of being a hero", Eraser Head told them and everyone looked at each other and nodded.
A man with a tattered suit and cracked mask walked towards them.
"Remember our creed!", Eraser Head said.
"GO BEYOND! PLUS ULTRA!", everyone shouted and charged.
The first death made everyone falter. A third-year student had his head blown off by a beam. The second death followed when a crystal spike lodged itself on a second-year's chest. And so, the massacre began.
Nejire flew above and shot blast waves at All for One but he shot blast waves that negated it. He created ice ravens and they flew towards her and froze her arms and legs, making her fall.
All for One continued killing those who charged at him. He snapped their necks, crushed their hearts, shot their chests, electrocuted their body, stab their stomach with a crystal spike, or turn them into living bombs. And while he was killing them, All for One felt joy as the heroes-in-training he once admired died so easily in his hands.
He was doing fine until flames were shot at him. However, those low-temperature flames were not enough to penetrate his barrier so he didn't bother to dodge. All for One looked at the source and saw a boy with red-white hair.
Everyone stopped and looked at him. His eyes were radiating anger. However, the burning anger wasn't a vengeful one but instead, it was the righteous fury of a hero when someone gets hurt.
"All for One. You have committed many crimes. You stole important things from families, students, and even society itself. I will not let you get away", the boy said.
"And who are you to stop me?", All for One asked.
Flames wrapped around the boy's left side and ice formed on his right side.
"I am Todoroki Shoto. The hero who'll take his father's name: Endeavor!", Shoto announced.
Strong gusts of wind blew and a boy landed right next to Shoto.
"And you might be?", All for One asked.
"I'm Yoarashi Inasa, a proud Shiketsu student!", Inasa shouted.
"And what do you want?", All for One asked even though he already knew the answer.
"Defeat you!", both said in unison.
Shoto made ice go to towards All for One while Inasa flew and shot strong gusts of wind. All for One shot a shockwave which destroyed the ice. The wind Inasa blew didn't go pass All for One's barrier. Vines wrapped around Shoto but he burned it to crisps.
I don't know what to feel about this… but it's just right to do this...", Shoto thought.
"PROMINENCE BURN!", Shoto shouted and high temperature flames blasted to All for One.
The two students fighting All for One were powerful and so, the others felt that they could do nothing but watch since they might just get in the way. They wanted to step in but their feet wouldn't move. It was like watching the two hero schools working together.
Shoto panted and immediately cooled himself down. He looked at where All for One was standing but the villain only had a few burns on his clothes. Large ice charged towards All for One but he just shot a stronger shockwave which destroyed it into chunks,
"I suggest you try harder if you want to 'defeat' me", All for One taunted.
"You're right", Shoto said.
Strong wind blew and the ice chunks were carried by the wind. All for One looked up and saw Inasa was making a tornado. Ice circled around the wind user and he shot all of it to All for One.
All for One thought in a split second using his Swift Thought Quirk. He couldn't use Prominence Burn since it would just be carried away by the wind. Chronopass' Quirk wouldn't work against that many projectiles. And his barrier has a limit on how much damage it can handle.
All for One teleported away from the spot and appeared behind Inasa. . He punched Inasa his enlarged and crystallized fist. Inasa made a crater when he crashed to the ground.
Shoto wanted to rush over to where Inasa landed but he felt immense fear emanating from behind him. He turned around and saw All for One standing away from him with a ball of black energy floating above his hand.
"This is a Petrification Ball. It's a Quirk that I can use once a day but I guess Endeavor's son deserves this", All for One said and shot it.
A certain hero made his move and bandage-like cloth wrapped around Shoto. Aizawa pulled him away. However, the dark ball hit Aizawa. His body slowly turned into stone starting from his feet. Knowing that this was the end, he decided to do one thing.
"Everyone listen!", he shouted.
Everyone's attention turned towards their teacher. With his legs already becoming stone, the students already knew it was too late.
"There is a difference between fighting an impossible foe and dying a heroic death. All of you may have accepted your fate but I will not allow you to do something irrational. All for One is too powerful for you. What you're doing right now is pointless. Don't be afraid to run. As long as the spirit of a hero is in you, there is still hope", Aizawa told them and the petrification already reached his neck.
Students, especially Class 1-A, started crying. Even though he was a harsh teacher, he cared about his students. After all, that was the reason why he was harsh in the first place.
"Now. Don't be afraid of running. That's all for my final lesson to you"
The pro hero, Eraser Head, turned into stone.
