Fridge

With the floor all covered in ice, they thought it would all be over. However, there was a certain crazy individual among them. 

"I'll destroy it all! All the ice!" Bakugo yelled before using the explosions on the ice, causing it to break apart. "THIS DAMN ICE WON'T STOP ME!" 

Midoriya's eyes went wide in realization, he started to do the same to the ice. With the power surging through his arms, the ice was quickly being broken apart. Uraraka was doing what she could, but with her quirk, it was hard for her to break down the ice. 

Ida was still frozen, so he couldn't move, and was forced to watch everything happen.

'Damn it, where are you Todoroki?' 

Eira applauded them, "Finally using common sense, that's what I like to see. However, I'm not waiting for you guys to finish breaking all the ice, see y'all later!" 

The four of them could only watch as Eira ran past them and was making her way towards the defensive side of things. 

"Let's hurry up! With that many people there, she shouldn't be able to defeat them all so quickly!" Midoriya said. 

"No, she definitely can get through them easily." Ida said. "Although I am frozen here, I did a quick analysis on her. From what I saw, she barely used her full speed, yet she was doubt quick. So if she decided to just run past everyone and get to Todoroki, she could do it." 

"But she won't do that, right?" Midoriya asked. 

Ida nodded his head, "It seems like she'll give everyone a chance until she deems it's over. But with her abilities, you guys will have to be quick about it. We don't know how serious she'll get." 

"Damn it…" Bakugo muttered. 

Eira was sprinting around with a grin on her face, in a split second, she had already frozen two people. Mineta and Ojiro, they were quite easy to freeze. Mineta was quite easy to bait, all she had to say was that Momo was behind him. 

"How gullible." Eira said with a giggle. 

The search continued as Eira's eyes scanned every perimeter for a sign, however, she didn't find them until she reached the very end of the limit where they were allowed to go. 

There, she saw everyone in front of Todoroki, it was like a "protect the president" kind of formation. She nearly laughed at the sight. 

"Seriously? This is what you guys came up with?" Eira asked. 

"Well…" Momo mumbled. "With only five minutes and the fact that you could come at any moment, we couldn't afford to come up with a better tactic than this one." 

"Alright, then let's-" 

"Sato! Koda! Shoji! Now!" 

Birds started to entrap Eira as Sato and Shoji quickly ran in to immobilize her. Their plan of action was to trap Eira using Koda's quirk as Sato and Shoji would use their strength to pin her down. 

But they highly underestimated her and their plan was too flawed.

"Birds? How are they going to trap me? At most, all they're going to die is bite me or maybe plant a few turds on me. Are you guys even trying?" Eira questioned. 

Within a blink of an eye, Eira was out of the trap, and froze the three around their feet.

"The problem with your plan is that it leaves you too defenseless and you're not considering what type of opponent you're going against." Eira said before glancing at the rest of them. "Now, who's next?"

"Jiro! Do it now!"

"I'm on it!" 

Kyoka plugged her jacks on the special sound amplifiers on her forearms, she used her elongated earlobes to remove the amplifiers from her wrists and direct them towards Eira in which it released a powerful, short-range soundwave. 

When Eira heard the sound, her entire body slightly shuddered, as she winced. 

'Sure enough, no amount of training can counter soundwaves.' she thought. 

"Tokayami! Do it now!"

"Right."

Tokoyami expanded the Dark Shadow's arms and wrapped its claws around Eira. For precaution, Ashido had spread acid around Eira's surroundings in case she was able to escape.

"Tokoyami! How are you holding up?" Momo asked. 

"Fine for now, she's not making any sudden-" Before Tokoyami could finish his sentence, he felt a shiver down his spine. "Guys, get ready!" 

"Huh? What's going-"

Ice started to envelop around the arms at a rapid pace as Tokoyami barely pulled away just in time. Eira's figure was finally revealed and she had a smile on her face. 

"What's next?"

All of the students stood there, most of the plans they all had thought of were completely thrown out of the window. They were aware of how strong Eira was, but to think even if they had all these people, they stood no chance. 

"Don't worry, there's still me." Todoroki said, standing before Eira. "It seems like this is our last resort." 

Eira immediately dashed towards Todoroki only to be met with an ice wall. 

"Not bad, your reaction is pretty quick."

"Of course, I'm going against you." 

"DON'T COUNT ME OUT! I'M THE ONE THAT'll KILL HER!" 

With perfect timing, Midoriya, Bakugo, and Uraraka had arrived when everything seemed like it was about to go down hill. 

"Bakugo! Midoriya! Uraraka! You made it!" Momo cheerfully yelled. "I thought you guys were long gone." 

"So what's the plan?" Midoriya asked.

"Actually…."

"WHO NEEDS A PLAN?! WE'LL JUST KILL HER! RAHHHH!" Bakugo yelled and mindlessly charged at Eira. 

The others stared at him with either admiration or thought he was a psycho. But his energy was what they needed, if nothing was working, why not just charge at her all together? After all, there's no way that she could handle all of them, right?

Out of nowhere, Eira had a pair of blindfolds on, and was doing a strange sign using her hands. Everyone was confused until they heard the certain words that shifted the energy on the battlefield. 

"Domain Expansion…"

"Alright, let's stop right there." 

Eraser Head had suddenly showed up when things were about to get serious. Eira was back to her normal outfit where she had shades on. 

"The test is over, Todoroki, your team won." 

"I'm not so sure about that." Eira interjected. "Look at his shoes." 

Everyone turned to what Eira was pointing towards and Todoroki was frozen at his spot. He was unable to move from the ice that wrapped around his legs, even though he didn't realize when this happened.

"When did she…"

"It was when she said Domain Expansion." Eraser Head said. "It's not actually what it sounds like so all of you can relax. It was just for a moment where she moved at a very quick speed that the human eye couldn't catch unless you're as experienced as me." 

"It's as he said, so is everyone ready to get in the refrigerator?"

Everyone groaned in realization when they realized what their punishment was. 

It was now the morning and everyone still felt cold. Their entire body was numb and could barely feel a thing. 

"Never again…I will not be trained under Zero. It's not a reward…it's a punishment."
