AN: In case you guys were wondering, Izuku's doing this out of arrogance, but desperation. I mean, what would you do, if there was only one thing on your mind, and fighting being one of your few chances of getting it?

..

"Umm… How about we… fight?"

A shocked silence followed this statement. The two adults raised their eyebrows, while several of the students gasped. They had all seen there sensei restrain Bakugou almost instantly, and wondered if he was insane, going that far to save someone who clearly hated him.

'Huh… I thought the report said he was level-headed… but this is clearly an act of desperation… Why would he go this far?'

Sekijiro glanced at his colleague, who didn't react at all, minus a slight twitch of the lips anyone who didn't know the man as long as him would've missed.

Of course, the two knew about the large group behind Midoriya, composed of Class B. And by the body language of the boy, he didn't.

Aizawa let out a chuckle, which startled the fidgeting green-haired student. "Interesting! But what about when you lose? It's not fair if I'm the only one wagering something, is it?"

Izuku's breath hitched. He already knew his chances of beating the Pro Hero- At most, less than one percent. At worst, a permanent injury. Still, Kacchan wanted to be a hero all his life, and was in this situation at least partially due to him.

Warily, he asked, "Wh-what do you want?"

The bedraggled man grinned widely, and answered simply, "If you lose, you get expelled as well."

Izuku was visibly paling and sweating now, but he nodded, his resolve firm.

"Izuku, no!"

"Don't do it!"

"Stop it!"

Jumping in surprise, he turned around to see some of the classmates he saved, looking increasingly worried- and for good reason. Itsuka and a few others were yelling at the top of their lungs, and he smiled slightly.

'So this is what it feels like to be accepted…' he thought, wavering, but he shook his head rapidly. "Sorry guys… I know we've just met, but I have to do this…"

Breathing in deeply, he turned back to his opponent, and nodded firmly this time. A shaky grin split his face, and he entered a battle stance. "I accept, Aizawa Shota, Pro Hero Eraserhead."

Wordlessly, Aizawa dropped Bakugou, who was strangely silent. Of course, that didn't mean he stopped glaring at Izuku. He glared even harder, if anything, before stomping over to his classmates, who were completely enveloped in the fight about to take place. Even Todoroki, the silent boy, took interest, though it was just wanting to see a Pro Hero in action.

"Ready, go," the man said emotionlessly and without warning, before taking his goggles and strapping them in place.

Expecting this, he jumped back immediately, just in time to avoid the capturing tool. As he weaved through the many lines, he thought rapidly.

'Eraserhead, former vigilante. The ability to erase quirks, the drawback is that it's only active with his eyes open and on his opponent.' he thought, ducking as another attack soared above him.

'His attack style is to eliminate the quirks and immobilize them with his unique tool, made with carbon fiber and a unique metal alloy. Both he and the tool are ridiculously fast, and no stranger to close combat." He jumped back as Aizawa suddenly appeared in front of the boy, hand outstretched. 'His goggles are also unique, serving to maximize his ability, and block flash grenades. If not for my training, I'd be done for immediately. Even so, he's probably holding back.'

Deciding that was all the information he had on the opponent, he switched to analyzing the environment. 'The gas tanks are about ten meters back, and an electric box is to my classmates' immediate left. The open space limits his city-based style, but I shouldn't underestimate him.'

Without realizing it, he had begun to mutter, his abundant knowledge shocking the other children. Even Aizawa was slightly disturbed by the amount of information he had. 'And I'm not even close to his favorite hero…'

Grimacing, the boy decided that any more delay, and he'd lose for sure. With a burst of speed, he ran to his right, towards the building…

"I have to do this! Kacchan's dream is to be a hero, everyone here as well!"

Only to double back instantly as the bandage-like material struck at the ground there. He sprinted to the left, ducking and twisting as if being punched at was second nature. Ironically, his short stature only made it harder to get at him, Eraserhead occasionally throwing blows at the height of an adult out of instinct.

"I know what people giving up on you feels like! Everyone should get a chance at their dream!"

'Shit!' the Hero thought, blinking fast. 'How the hell is he evading this? And my eyes are getting sore, dammit. I guess I won't hold back anymore...'

With a yank, the white threads formed a loose barrier around the boy, who suddenly looped back to Aizawa. With a jolt of realization, he realized he had sent almost all of his capturing tool there, which may have blocked the boy, but in turn left him without anything to work with.

Desperately, Midoriya drew back his fist and thrust forwards, without using his quirk.

"PLUS ULTRAAAA!"

And was blocked mercilessly, as Aizawa pulled out another roll of the scarf-like tool.

Without a moment's reprieve, Izuku was bound tightly by the clothe, struggling slightly.

Smirking, the older combatant let him go.

Defeated, Izuku slumped to the floor. Out of the corner of his blurry eyes, he saw Bakugou scoff, stomping off to who-knows-where, while Aizawa squatted down to him.

Grudgingly, the man smiled at him. "You fought well."

Sadly, Midoriya nodded. "A-and my e-expulsion…"

The man stood up, and turned to the building. Without showing his face, he replied emotionlessly, "About that. I lied. Neither of you are expelled. Good luck, Young Midoriya."

Without another word, he walked off, and his classmates swarmed him immediately.

..

I couldn't wait, and immediately set to writing another chapter. I expected to fall asleep and finish it tomorrow, but, oh well. Turns out I didn't.
