Death

After about 5 minutes everyone heard a horn and separated into different groups. All of the students made their way to the second floor, they weren't ideal and kept an eye out for any traps. Surprisingly, there weren't any, like at all. They were thinking Nero would at least block the entrance but he didn't do anything.

Arriving on the second floor they saw Nero sitting on a chair made of ice with a dome of water behind him. He said, "Finally, well, let's get this over with I'm a busy man."

Some of them separated but soon after Nero waved his hand, in the next moment all of them dropped to the floor. "You're quite stupid, I can control any liquid, not just water. And you're all made up of 70% of it."

"That's bull!!" they all shouted. Nero allowed them to talk but the rest of their bodies couldn't move, at all. Welp! Guess there will be no epic fight between Nero and 1A, how unfortunate.

Only people significantly stronger than Nero can break out of what he did, and these children were pretty weak. They had no chance of resisting it, most of them will never be able to resist it. They, unfortunately, had to wait for 15 minutes, Nero was on his phone shouting at All Might who was on the other line, "Just end it already, they ain't getting up!"

Nero was a little upset, he hated to waste time, and this was wasting time. He just wanted to go get food.

"Sorry, Yong Nero but there are rules.."

"You are literally the one that changed the damn class, don't you dare talk about rules." Nero put the phone on speaker and make a platform of ice then put his phone on it. He scratched the top of his head.

"Sorry, the line seems to be..."

"If you hang up this on this call I swear to every God from every fiction that I will hang, YOU." Nero's voice was low but everyone heard him. The students on the ground felt a chill run through their spins.

All Might who was in an observation room with a few others, also sweatdropped. All Might gulped and put the call on mute, he looked at his fellow teachers and said, "What do I do, help me."

All the teachers took huge steps back and shook their heads. One said, "He's too scary." "You're on your own, I'll pray for your safe return. If you live long enough that is." another said.

Aizawa showed up out of nowhere and said, "Don't die please, then I'll have to take over your classes." he got into his sleeping bag and crawled away, compiler style.

All Might looked at them stunned, they didn't even try to help him. All Might looked at the phone but heard Nero it, "You didn't put it on mute stupid, you put it on video."

He saw Nero sitting there with his legs crossed and his eyes were glowing bright yellow. All Might rubbed his eyes and the glowing was gone, 'Was I just seeing things?' he wondered. He never saw Nero's eyes nor horns ever glow so he just thought it was just him.

All Might did the only thing he could think of, he hung up the phone. All the teachers shook their heads thinking, 'He's a dead man.'

Aizawa crawled back and said, "That wasn't smart, now you're going to die. Good luck."

"What was I meant to do?!" All Might screamed.

"Stop being so loud, and you could have just ended it. It's obvious they are not getting up as he said. But, you did something stupid." Aizawa said while crawling away.

Now All Might was fucked, royally fucked, he was so fuck... I'll stop. The point is that he is fucked. All Might sat down and contemplated his life choices. After a minute he realized how fucked he was.

Nero can't beat him but, he could just make him use up all his time though. Nero and All Might were confident in him doing that. Nero was good at long and close-range fighting.

With Nero

After All Might hung up in Nero, he put his phone into his pocket and made a cup out of ice, the cup filled with water, and Nero drank it. He finished it and said, "Imma kill him, no, I'll hang him in front of the school but naked, yeah. Or should I take a page out of high school girls and humiliate him at prom. Does U.A even have that, I'll think about it later?"

Nero looked at the time, he realized it only had about 6 minutes left of the timer. Nero decided to just say fuck it and left the warehouse. He allowed the students to move before he was gone, he went to the cafeteria right after. This whole thing was very boring and pointless, Nero didn't get shit out of this.

Sometime later, a certain number 1 hoer was walking to the exit of U.A to leave since the day was over.

"Where are you going, what, did you think I was joking?" All Might slowly looked back and saw Nero with chains made of ice. All Might said, "Young Nero I..." He stopped mid-way and ran. Nero ran after him and said, "Get back here you little bitch, it's only death, nothing much."
