MHA: Radahn

The training arena was silent, save for the faint hum of flickering lights and the slow, laboured breaths of Class 1-A's students. Their bodies ached, their minds reeled, and their pride was shaken. Hoshigami Enrai had utterly dominated them, all without using a single ability.

Shoto Todoroki clenched his fists, staring at the ground. He had never felt such a disparity in skill before.

Bakugo, on the other hand, sat with his arms crossed, fuming in frustration. His explosions were meaningless against someone like that. He knew Radahn had something up his sleeve, but this was beyond what he expected. "Tch. What the hell was that?" he muttered under his breath.

Kirishima groaned, rubbing his sore arms. "Damn, I thought my Hardening would at least do something, but it was like punching a damn mountain!"

"Y-yeah, that was insane." Kaminari said, still shaken. "I barely saw him move before I was sent flying."

"That wasn't a fight," Jiro added, adjusting her earjacks. "That was a one sided beatdown."

Ochako looked at Midoriya, who was still unconscious, resting on the side-lines. "But Midoriya , he actually landed some hits."

Bakugo just clicked his tongue at this remark.

Todoroki remained silent , his eyes fixed on the ground.

Sero nodded. "Yeah, that was crazy. When he went all green and blurry, I thought he might actually do some damage."

"But in the end" Asui spoke, her usual calm tone laced with concern. "It didn't even matter."

Aizawa, who had been watching from the side-lines, finally walked forward.

"That's enough. Get up, all of you. This was an assessment, not a battle you were supposed to win."

The students groaned as they got to their feet, still feeling the bruises from their overwhelming defeat. Meanwhile, Radahn stood tall, his arms folded as he observed them without emotion.

"This is the gap between you and me" he finally said

"Now, will you spend your time complaining, or will you work to close it?"

The students fell silent, some of them lowering their heads in shame while others looked at Radahn with an aim , He is the one they want to surpass.

Aizawa sighed, signalling for the class to return to their homeroom. "Let's go. You'll have more chances to prove yourselves later."

As the students slowly made their way back, Radahn remained behind for a moment, watching them leave. He then turned slightly, sensing someone approaching.

It was All Might.

The No. 1 Hero stood tall, his ever-present smile slightly dimmed as he observed Radahn.

" Haahahah! Hoshigami-san , That was quite the display" he said enthusiastically.

Radahn turned to him, his golden eyes unreadable. He looked at All Might for a moment before speaking.

"So, you are this world's strongest hero?" he said, his voice carrying an edge of curiosity.

All Might raised a brow. "Oh? You sound like you expected something different."

Radahn didn't reply immediately. He simply gazed at All Might, his eyes scanning him—not just his appearance, but something deeper. Then, his lips curved slightly.

"It seems you are injured."

All Might's entire body froze. His smile disappeared for a brief second, his eyes widening in shock.

Radahn turned away, beginning to walk off.

But before he could take another step, All Might spoke.

"Wait!" he said, his tone serious. "H-how do you know that?"

Radahn stopped but didn't turn around. There was a pause, a moment of silence that felt like eternity. Then, he simply continued walking, leaving without a single word.

All Might stood there, staring after him, his mind racing. 'How did he know?'

Later that evening, All Might found himself in Nezu's office. The small, intelligent principal sat behind his desk, sipping his usual cup of tea. His black eyes gleamed with curiosity as he noticed the tense expression on the Symbol of Peace's face.

"I take it you have questions, All Might?" Nezu said, placing his teacup down.

All Might didn't waste time. "Who is Hoshigami Enrai?" he asked bluntly.

Nezu chuckled lightly. "He is exactly who he says he is—your new combat instructor."

All Might narrowed his eyes. "That's not what I meant, and you know it. That man is dangerous. He overpowered an entire class of students, without even trying. He unlocked Midoriya's Quirk somehow, something even I don't understand. And worst of all" All Might clenched his fists. "He looked at me, and in mere seconds, he knew I was injured."

Nezu was silent for a moment. Then, he let out a small sigh. "I had a feeling you would come to me about this."

All Might leaned forward. "So? Who is he, really?"

Nezu's expression didn't change, but his grip on his teacup tightened ever so slightly.

"All I can tell you," he said carefully

"Is that Hoshigami Enrai is not someone you should consider an enemy."

All Might's jaw tightened. "And if he becomes one?"

Nezu smiled faintly. "Then, we will all have far bigger problems than just protecting U.A."

Silence filled the room.

For the first time in years, All Might felt something unsettling. Something he hadn't felt since his first battle with All For One.

A sense of true, undeniable dread.

---------------------------------------------------------------------------------

Days passed, and the students of Class 1-A gradually adjusted to the presence of their new instructor, Hoshigami Enrai. His methods were unconventional, his demeanour unreadable, and his combat prowess undeniable. Unlike Aizawa, who focused on discipline and control, or All Might, who emphasized strength and spirit, Radahn's teachings revolved around something different—adaptation and survival.

The training ground was silent, save for the occasional rustling of the wind. The students stood in formation, waiting for their lesson to begin. Radahn observed them with his piercing golden eyes, arms crossed.

"Tell me" he finally spoke, his deep voice commanding attention.

"What is the greatest weakness of a hero?"

Iida adjusted his glasses. "A hero's weakness is their inability to prepare for unforeseen situations!"

"Wrong," Radahn said immediately. "You can't prepare for everything."

Todoroki furrowed his brows. "Then what is it?"

Radahn stepped forward, his presence alone feeling suffocating. "The greatest weakness of a hero," he said, his voice unwavering, "is the belief that power alone will save them. It is the belief that battles are won only through strength rather than survival."

The class was silent.

"Today," Radahn continued

"We are not learning how to fight. We are learning how to survive."

With a wave of his hand, the floor beneath them shifted. The training area transformed, suddenly resembling a ruined cityscape—crumbling buildings, shattered roads, and thick dust clouding the air.

"The scenario is simple," Radahn explained. "You are civilians. Your job is to escape."

Kirishima tilted his head. "Wait, escape? From what?"

Radahn smirked.

Before anyone could react, a sudden tremor shook the ground. In the distance, shadows emerged—autonomous combat drones, their glowing red eyes locking onto the students.

"You have five minutes" Radahn said. "Move."

The training immediately descended into chaos.

Bakugo blasted off the ground, snarling, "I'm not running from some stupid robots!"

Todoroki created an ice path, leading some of his classmates to higher ground. Midoriya analysed the terrain, formulating escape routes. The others scrambled to navigate the environment, dodging the pursuing drones.

Radahn watched from a distance, arms still crossed.

"Survival is not about defeating the enemy" 

"It's about knowing when to fight and when to flee."

As the lesson continued, the students slowly realized that brute force wouldn't save them. They had to think. They had to work together. And most importantly—they had to adapt. Some, like Iida and Yaoyorozu, tried to analyze the enemy movements, while others, like Kaminari and Jiro, used their quirks to sense safer routes. After multiple failures, Midoriya finally shouted,

"We need to distract them! Half of us should draw their attention while the rest escape!"

Following his plan, they managed to flee successfully. As the timer ended, the simulation stopped, and Radahn observed them with a neutral expression.

"Not terrible," he said, "but not great either. You survived, but only because I allowed you to. Remember this—heroes die not because they're weak, but because they refuse to run when they should."

With that, he dismissed the class, leaving them in deep thought as they returned to their classroom.

Outside the school, reporters had gathered, pushing against the gates with cameras flashing.

"Endeavor's son, Shoto Todoroki, is in this year's class! Will he surpass his father?"

"Pro Heroes are saying this year's batch is exceptional. Could we be witnessing the rise of the next generation?"

"The Symbol of Peace, All Might, is teaching at U.A. now! Is this a sign that the school is prioritizing strength over education?"

Students walking through the entrance glanced at the commotion, some whispering among themselves. Kaminari muttered, "Man, they really don't let up, huh?"

"They're just trying to get headlines," Jiro added, rolling her eyes. "And if they don't get an answer, they'll make one up."

Todoroki ignored them, passing through the school gates without acknowledging the reporters. Bakugo, on the other hand, scowled at the sight, clicking his tongue in irritation.

As the doors shut behind them, cutting off the noise of the media, the students dispersed to their respective classrooms, finally escaping the persistent questioning.

Later that day, during lunch, the cafeteria was buzzing with energy. Students chatted and laughed, recovering from the intense morning lesson. Trays clattered, food was served, and the air was filled with the smell of freshly cooked meals.

At one of the tables, Midoriya sat with Uraraka, Iida, and Todoroki, still thinking about the survival training.

"That lesson was insane," Midoriya muttered, taking a bite of his food. "It wasn't just about fighting, it was about knowing when not to fight."

Uraraka nodded. "Yeah, it really felt like we were civilians caught in a battle."

Todoroki remained quiet, deep in thought. "Hoshigami-sensei, he's different from the other teachers."

Across the room, Bakugo sat with Kirishima and Kaminari, still scowling. "Tch. What kind of hero training is that? We should be fighting, not running away!"

Kirishima laughed. "Dude, admit it, that was tough. I barely made it out!"

Before Bakugo could reply, the overhead lights suddenly flashed red.

The shrill wail of an alarm blared through the cafeteria.

Students froze mid-bite, eyes widening in confusion.

"W-what the hell!?!" Mineta stammered, nearly dropping his tray.

Jiro's earjacks twitched. "That's not a fire alarm."

"Villains! They attacked UA" - someone shouted from the crowd.

Iida immediately stood up, his voice cutting through the noise. "Everyone, remain calm! We must follow emergency protocol!"

Despite his words, chaos erupted. Students stood up, pushing toward the cafeteria exits, some panicked, others confused.

Midoriya's heart pounded. 'Was it an attack? A villain?'

Then—

The alarm stopped.

A moment of silence passed before the intercom crackled to life. "False alarm. Repeat—false alarm. The system was triggered by unauthorized personnel. No threats detected."

Seconds later, a teacher entered the cafeteria, raising a hand to calm the students. "It was just some reporters trying to sneak in. They triggered the alarm system. There's no danger, so return to your lunch."

The students let out relieved sighs.

Kaminari slumped back into his seat. "Dude, I nearly had a heart attack!"

Mina groaned, placing a hand on her chest. "That was not funny!"

Midoriya, however, was still on edge.

'Unauthorized personnel? Reporters or not, how did they even get close enough to trigger the alarm?'

Sitting a few tables away, Radahn silently observed the chaos, his expression unreadable.

He exhaled slightly. 'So, this world isn't as secure as it seems.'

As the students returned to their meals, a quiet sense of unease lingered in the air. This was just a false alarm.

But what if next time, it wasn't? or maybe it wasn't a false alarm at all.

As Radahn calmly observed the students settling back into their meals, a flicker of something unseen passed through his eyes. His vision shifted—colours faded into muted tones, outlines sharpened, and the world became a translucent, layered construct of energy and matter. This was not mere eyesight but something far beyond—Astral Perception.

Through this ability, the school's walls were no longer obstacles, and the boundaries of space blurred. As he allowed his gaze to wander, it passed effortlessly through the cafeteria walls, tracing the corridors, the faculty rooms, and then—movement.

A lone figure skulked in the shadows of a desolate room deep within the school's restricted area. Their presence was unnatural, deliberate, each step cautious and calculated. Not a teacher. Not a student. Someone who did not belong.

Radahn's gaze narrowed. 'Unauthorized personnel, huh?'

For a brief moment, his fingers twitched as if contemplating action. But instead, he leaned back slightly, tapping the table with a single finger.

"An uninvited guest."
