A lot changes Here this chapter. It'll to a different end because of Izuku. So you'll probably see a lot of alterations in the Rescue Training arc.

(Sorry for the delay!)

"Get back!"

Aizawa barked sharply, quirk flaring as he hopped out of danger's way with Thirteen. The students complied out of instinct, following the orders without question as they huddled behind the safety of Shouta's and Thirteen's arms.

On cue, a portal beneath them opened, swirling with dark lavender hues. It looked endless with the pitch black center.

Several other portals opened up on different surfaces, all swirling with various intensity, before a large scale one opened in the very middle.
Shouta got a glimpse of what was inside, and he can't help the shiver up his spine.

Villains.

A person (or what seems like a person) walked out, slouching down while his hands hung by his (hers? Their? Shouta doesn't care.) sides.
The first noticeable thing were the severed hands all over his body, attached to his neck, his arms, and his fucking face. A single red eye peeled out of the open column of the fingers, glazed over.

Another villain followed him, who seems like he had.. The void as his body. Like a purple flame wearing a bartender's tux.
He had yellow wisps on what Shouta could guess as his eyes, flickering in a form of blinking. The dark purple- almost black- colors matched the portals. They were almost like warp gates.
The portal in front of him radiated power, as if it was a lesser form of Thirteen's black hole, which was making a weak effort in sucking them in.

Other hideous villains- some still looked slightly humanoid- filed out slowly. The air was thick, and Shouta could practically smell the fear in the air from his students. Fuck.

The hero and Villain counter parts stood both of their grounds, Thirteen getting ready to pop off the caps on his fingers that were suppressing the black hole.

He felt Thirteen tense.

"Aizawa."

"What," he practically snapped back at Thirteen, gritting his teeth.

"The kid."

Their voice was calm, but it managed to make Shouta almost have a heart attack.

There, right in front of them, was Izuku, standing on the first step of the set of stairs leading down to the villains. Back turned to Shouta, Aizawa heard the panicked chatter behind him.

'The kid!'
'Aizawa-sensei! Izuku's-'
'He's unprotected!'

The fear of the students almost seeps into his own system, but he shook it off.

Izuku stood there momentarily, head tilting to the side as if he were curious. A childish action that drew attention to himself.

The low-class villains gawked at the kid, taking notice of his calmness and stupidity. They crowed, taunting the boy with words and shrill laughing.

Aizawa cursed to himself, scarf floating around his neck as the ribbon like ends twisted in the air like a dangerous snake.

"Hisashi."

At that moment, Aizawa swore the whole fucking USJ stilled.

Everyone froze, gazes trained on kid with terrified eyes. Well, not directly "at" the kid. No, no. The physical appearance of the kid was very adorable, not suited by his quirk. And speaking of his fucked up quirk, there, just beside him, materialized a man with sleek red hair and tidy suit.

He stood there as Aizawa ignored the shell-shocked gasps from Thirteen, the Villains, and his students.

Where the FUCK did he come from-

"Izuku-kun," The man with the deep voice hummed. Shouta's instincts went haywire when the man laid a hand on the small boy's shoulders, pulling him close to his leg and ruffling his green hair. It was a gesture of comfort; affection. Izuku's hand grip his pant leg tightly, hand outstretching to point at the blue-haired villain freak who was smack dab in the center of all the chaos.

Shouta's mind raced quickly as his heart. Shit. Shit. SHIT. Was that the demon he encountered? Was he the one in Izuku's body earlier?

Fuck!

He had zero knowledge on how capable the quirk is. Will Izuku cause a havoc? Will he destroy USJ?

Is the quirk capable of killing?

That sent a shudder up Shouta's spine. Heroes captured Villains live. They normally do that. They don't downright kill them on the spot.

The man suddenly did a complete 180 that scared the living shut out of Shouta.

There, Aizawa could see his green, illustrious eyes, a shade of red mixed in it. They looked gentle, but behind it laid fire. Fire dancing around, crackling with such anger, anticipation, and mischief. Like a calm before a storm. They were.. They were similar to Izuku's.

Another noticeable feature were the two jutted our horns from his head, curling on the tip like a spring. They were sharp but big as a bull's.

A Demon.

A real life fucking demon.

Jirou shakily clasped her hand on Tsuyu's shoulder, fear crawling up her throat- because somehow, He was was giving out more fear than the League of Villains. She was going to throw up the pancakes she had at breakfast. Uraraka was hyperventilating, the reality of being a hero crushing her with weight. She glanced at the spot Iida was supposed to be standing on, only to be greeted by an empty space.

She was alone now, no more friends to turn to.
(With a trembling lower lip, she doubts that she was even ready. Should she quit?)

The Demon was as "safe" as a cobra waiting to strike.

Kaminari shook beside her, Hagakure whimpered, and Mineta was freaking out and crying.

Everything was practically in silent chaos.

Hisashi's mouth twitched up to a smile, an expression that betrayed the ill intent of his dark eyes. "I suppose I owe all of you," his voice practically echoed in the silent USJ, bouncing off the walls into a repeating rhythm. "For taking care of my... Son."

Aizawa's whole body felt tremors going through. In amidst all the evil, he can't help but feel.. Jealous? But what the hell should he be jealous of? Izuku's father chuckled deeply at Shouta, green eyes burning through him, as if fire licked his body. The fear and stress alleviated suddenly, as if he was plunged in a tub full of warm, comforting water.

"I will trust you to take care of Izuku. And because I owe you for that, I'll take care of this situation."

Izuku smiled toothily.

"Aizawa Shouta. My service will be free of charge."

And at that moment, the ground rumbled, cracks on the concrete ground smoothly snaked on the earth, before breaking off into spider web formations. Green hell fire blasted out of the crevices, the sweltering heat scorching everyone even though the fire wasn't touching them.

Well, not the students and teachers, of course.

A split second after the flames were barfed out of the ground, hellish screeches from the villains made everyone's legs wobble from the intensity of the cries of pain. The distinct smell of burning hair, flesh, and other materials made Bakugou choke.

Heat stung his eyes, but he wasn't as affected as his other classmates; considering his quirk was hot. He built up a tolerance for hot things.

Bakugou stood there, a blank, dumbfounded look on his face as he gazed at the person (he doubts it's actually human) beside Izuku, green eyes matching the hell fire around them. Katsuki.. He was lost. He was lost like the others.

'What was he supposed to do, anyway?' He chided himself. 'It's not my fault that the villains are roasting to death'. And truly, it really wasn't.

"Keep. Them. Alive."

The man beside the giggling Izuku raised a peculiar eyebrow at Aizawa's weird demand.

Wouldn't he want to get rid of these scums who dared attack children? Who were desperate enough to even turn off U.A.'s alarms in an effort to hurt youths?

But nevertheless, he hesitantly complied as the fire vanished into neon wisps in the air.

The metal holsters were melted, the USJ buildings were crumbled into ashes, (even the buildings in the fire zone were in ruins) and even the damn boat in the water rescue section wasn't even there anymore.

Thirteen's breath hitched as they saw the villains.

They looked horrid.

They looked so...

Distorted and melted.

It was disgusting, and even if they don't have a throat for food to pass in, they were certain to throw up at the disgusting rotten smell. It was like burning a bag of garbage but ten times stronger.

Aizawa gagged at the sulfuric smell, before seeing "Man-child with a hand fetish" and "evil portal guy".

Both were too stunned.

The hand man brought his hands up, shakily digging his grimy dirty nails into his neck and embedding long, deep scratches. He was muttering something, body shaking all over. He was, by no surprise, loosing it.
The purple flame (mist?) guy looked at Izuku, unaffected by the flames. Somehow, even Hand Man wasn't even touched by the unbearable heat. Shouta hunched that this was.. Intentional.

In a different scenario, Kurogiri would be amazed on how much power the child held. The waves of energy practically rolling off of him, and it was clear that if the green haired four year old was steered in the right direction, he would certainly become an unbeatable villain.
But on how "this" played out, he was less amused because of the fact that the kid was a certain threat.

He was weighing the pros and cons of yielding or continuing on the mission, undisturbed by the melting puddles of villains beside him. A normal occurrence. No matter. They could easily be replaced by more wannabes desperate to rid heroes.

Before he could come to a decision, however, the man-child (also known as Shigaraki Tomura) rasped out from his scratchy voice box.

"Nomu. Bring the child to me."
