Eijirou was hiding in a building with an outside layer made completely of tinted blue glass. It greatly resembled an office, and he was marvelling at the detail in the setup when someone came crashing through the glass and landed in front of him in a crumpled heap. Eijirou just stared at the boy as he uncurled himself and got up, dusting himself off. He only seemed to notice that Eijirou was there after a minute of checking himself.

"Ah, there we go," he said with a… somewhat evil smile? It was still polite, somehow, like one of those prim and proper supervillains. "Your firecracker friend really got me in the mood. Please," he calmly added with a mock bow, "put up a decent fight."

"Hell yeah!" Eijirou said, smiling enthusiastically. He bumped his fists together and the familiar hardness of his Quirk activating spread from his hands to the rest of his body. The boy before him quirked an eyebrow.

"Oh, so you're the stony guy. Man, that's disappointing," he huffed. Eijirou was rather taken aback by this. Disappointing?

"W-what?" he stammered in surprise. That was rather… humiliating. That the elites didn't even think him a worthy opponent. "That's harsh, bro. You couldn't be a bit less direct about it?"

"I'm not here to make you feel better," the guy waved him away. Then his face brightened and he leaned in. "Say, who are the strongest people in your class?"

Eijirou backed away a little, his hands raised. "Um, I don't know, Todoroki? Bakugo? Midoriya's pretty powerful too… and Yaoyorozu can do a bunch of stuff."

"I see, I see," the boy mused. "What do they look like?"

"Todoroki's hair is half-red-half-white, Bakugo is always angry, Midoriya has green hair, and Yaoyorozu wears a really revealing outfit. She also has this really unique ponytail."

"Right, got it. Thanks for the help, my man. Ciao," the boy turned around and walked away, lazily raising a hand to bid him farewell. Eijirou felt a little nervous, and he just had to ask.

"Aren't we going to fight?" he asked weakly.

"Hm?" the guy turned around. He appeared to seriously consider the question, and after a few seconds pondering, he looked at Eijirou with a bored expression and sighed.

"Well, that is the point of the exercise, but I don't want to do more than I have to," he pouted. He ran his hands through light brown hair and looked back at Eijirou with narrowed eyes.

"Fine," he relented. "I'll fight you."

He sprang at Eijirou too suddenly for him to react and a hand slammed into his forehead with immense force. Eijirou just thudded into the cubicle division and fell. The world was a haze of blurred colours.

"You still awake?" the boy asked. He nudged him with a foot, and the only response Eijirou gave him was a groan. He got up, shaking his head, and was almost surprised when his opponent let him. His eyes were clearing, sharpening. The world was coming into focus again. His thoughts were coherent.

His opponent made to kick him, without taking the hands he'd slid into his pockets out. Immediately, Eijirou dodged out of the way and punched him in the stomach with as much force as he could muster. The boy didn't even move. It was like hitting a mountain.

"Oh, so you're going to fight, then?" his adversary smiled with a sort of bored, reluctant enjoyment. His hands came out of his pockets, and his feet shifted.

Eijirou found himself hurtling through the office, which was rapidly being demolished. The boy had his arms crossed in front of him, and he was pushing Eijirou with a power that Eijirou had only seen a few times before.

This guy was like Midoriya, or Satou when he had a lot of sugar. A heavy hitter. No, this was even more intense. It was like the time they had raided the Shie Hassaikai, and his impenetrable defense had been broken.

The person he was facing right now was on the same level as Rappa. Maybe even stronger.

Eijirou paled under his hardened skin. He would have to try it. Even if he could only hold it for half a minute, that would have to be enough.

"Red Riot Unbreakable!" he yelled, and his body shifted to become the hardest it had ever been. His torso? Unbreakable. His arms? Unstoppable. His eyes? Impenetrable. He in himself?

Invulnerable.

And with a roar of courage, he flung himself straight into the fist of his opponent, and took the blow.

He was unbroken, but the momentum and the force behind the strike catapulted him backwards into a desk, which toppled over, and he fell on top of it.

"Oh, I like this," the boy said, coming up behind him. "I really like this. You're going to put up a fight, huh? Let's see how good it really is."

Eijirou sat up as well as he could, laying on two sides of the edge of the desk. As his hands settled against the ground to steady him, his fingers found a hammer.

A hammer.

Why was there a hammer in an office?

Oh, who cared about the whys and hows? He'd been given an opportunity, so why not take it?

He jumped to his feet and drove the hammer into his opponent's head with as much force as he could muster, because clearly this guy could take a hit. It connected with a resounding crack. Eijirou blinked. That didn't sound good.

The boy staggered sideways, holding his temple, his hair swinging down over his face to cover his eyes. Eijirou froze. A few seconds passed.

Nothing happened for a bit. Then his opponent straightened, and his eyes came into view.

Eijirou really began to feel afraid then, because why was there amusement in his eyes?

"Thanks," he said casually, a hint of sarcasm in his voice, and then he punched with a speed that rivalled Iida's legs.

Eijirou's iron-hard defenses shattered like glass. Even as he yelled in agony from his skin being not just torn, but fractured, his flesh bleeding as hard as it could manage, Eijirou had the very surreal thought that if Tetsutetsu was in his place, his steely body with be irreversibly bent and dented. The thought of a warped, misshapen Tetsutetsu made him smile, the look probably out of place among his screams.

Through the red in his eyes, he could see the boy who had punched him looking very concerned.
