The Secret Life Of A Not-So-Useless Deku // A Vigilante Deku AU

Cursing Nedzu, For A Reason Of Course

Deku sighed as he knocked on the door of classroom 1-A. Nedzu annoyed him. He wasn't a fucking errand boy! Why did he have to deliver those papers? Wasn't analysing them enough, why did he have to meet the students?

He opened the door and walked in, attracting the attention of the whole class as he walked in, clicking his tongue in annoyance.

"The reports, Aizawa." Over the time he spent there, the two sleep deprived people had gotten quite closer, and so he'd dropped the 'san'.

The students flinched at his distorted voice, but he payed them no mind. How annoying, to actually have to show himself. He groaned internally. He was so going to get back at Nedzu for this.

A boy with blue hair and weird hands (Iida Tenya, his mind supplied) stood up, and started doing chopping motions.

"It is inappropriate to call a teacher so rudely in this school. And you aren't wearing the school uniform. That is very disrespectful behaviour!" he practically shouted.

Deku sneered at him, his hardened eyes narrowing being the only indication.

"Who said I was a fucking student here, you shitty robot?" he spat in annoyance, then walked over to Aizawa, handing the papers over to him, as the students gaped at him.

He was walking away when Iida spoke up once again.

"Such rude behaviour is unfitting for someone attending a prestigious school such as UA. Seize this behaviour at once!"

Deku sighed, his head twitching in annoyance, and he turned around, cracking it.

"Look, I already told you I'm not a fucking student. Unlike you morons, I already finished my schooling long ago. I do not have any intention of getting along with you. So just fuck off." He swirled around, nodding towards Aizawa, then walked away. "I'm going to kill Nedzu, that bloody bastard!"

The he slammed the door shut behind him and walked away.

The students gaped at the door. Who was that kid? He looked their age, but he wasn't a student there. So what was he doing there?

Iida turned to Aizawa.

"Aizawa-sensei, who was that rude person?" he asked, and Aizawa groaned.

"He's a friend of Nedzu's. You might know him as the hacker, Deku."

Some of the students gasped.

"The Deku?" cried out Kaminari. "But he's our age!"

Aizawa groaned once again. Damn Nedzu and damn Midoriya for leaving this on him.

"That is correct. But let me warn you, he isn't a staff member, or a student. He's a regular visitor, you could say. He has no affiliation with the school, and he isn't on the side of the heroes nor the villains. So don't pester him, or he will ruin you."

Iida jumped up once again.

"But Sensei, how could you leave him be? Isn't he a criminal then?"

Aizawa rubbed his nose.

"It isn't that simple." he said, gazing upon every single one of them as he did so. "Deku gives us important information in exchange for his immunity and neutrality. If not, he probably would've slid to dark side of society long time ago. Although from what I know, he doesn't like villains either."

Iida was about to speak up again when their door slammed open, hitting the wall loudly.

Deku had come back, and was swearing darkly.

"That motherfucker! I'm going to kill him!" he growled, then stomped to Aizawa, handing another piece of paper. "Nedzu fucking wants me to assist with the physical factor of the class. All Might's going to be there, right?" At Aizawa's uneffected nod, as he was used to his anger issues, he screamed in anger. "That damn Rat Satan! He knows I hate that matchstick! See when I destroy you fucking air ventilation, you bastard!" He then turned to the camera in the corridor, and flipped him off.

Aizawa just huffed.

"If you shut up, I will continue with this lesson." he said, and Deku spun around, glaring at him.

"I know they were asking about me, Aizawa. You weren't teaching shit." he spat, then turned around, walked to a corner, slid down, and sat cross-legged with a huff.

Aizawa sighed in exhaustion for the umpteenth time that day, and started the lesson on support items, while half the class stared at the boy covered in green and black, who glared at them if they met his eyes.

Needless to say, if was a long lesson.
