The first training session began in the most unconventional way possible. No announcements, no motivational speeches, and certainly no warm-ups. As the students of the rehab program filed into the gym, they were greeted by the sight of me standing at the front, arms crossed, wearing a sharp, tailored tracksuit—because, of course, I wouldn't be caught dead in anything cheap.

"Welcome to hell," I announced, my tone deadpan, the words reverberating in the cavernous gym. "For the next few weeks, you will hate me. You will curse me. And if you're lucky, you might even survive."

Toga snickered nervously, her usual playfulness cracking under the tension. "Izuku~ this is a joke, right? You don't actually expect us to—"

"Run," I interrupted, pointing to the track that circled the gym.

"Run?" Shigaraki asked, his dry voice already laced with annoyance. "What's the point? We're here to fight, not—"

"Run now," I barked, my voice snapping like a whip. The sheer force behind it startled even him. "Or I'll personally drag you around this track by your ear."

The group exchanged uneasy glances, but the look in my eyes left no room for debate. Reluctantly, they started jogging, their movements slow and uncoordinated.

"Faster!" I shouted, pacing alongside the track. "Do you think the heroes will wait for you to catch your breath? Do you think they'll care if you're tired? Move!"

Toga tried to giggle her way out of it, slowing down after just two laps. I appeared beside her in an instant, grabbing a stopwatch from my pocket. "Congratulations, Toga. You've just failed the first drill. That's ten extra laps for you—sprinting."

"What?!" she whined, her tone edging toward hysteria. "That's not fair!"

"Fair?" I laughed, the sound cold and biting. "Do you think life is fair? Do you think the world cares about fairness when you're on the battlefield? Run. Now."

The others quickly picked up their pace, not wanting to be singled out next. By the end of the first hour, Dabi had collapsed to his knees, panting heavily, his usually calm demeanor shattered.

"Get up," I said sharply, looming over him.

"I can't—"

"You can," I snarled. "You're just choosing not to. Get up, or I'll make you regret it."

He groaned but forced himself to his feet, his legs trembling as he resumed running.

The second phase of the session was worse. After an hour of relentless cardio, I had them move to the obstacle course I'd personally modified. Walls were higher, tunnels narrower, and the ground littered with traps designed to test reflexes and agility.

Shigaraki was the first to balk. "You've got to be kidding me. This isn't training—it's torture."

I smirked. "Exactly. Now climb that wall before I decide to add another ten feet to it."

He gritted his teeth, glaring at me, but eventually began scaling the wall. He fell twice, scraping his hands, but I didn't let up. "Again. Until you can do it without falling."

By the end of the obstacle course, most of them were battered, bruised, and barely able to stand. Toga had mud smeared across her face, her usual cheerfulness completely gone. Dabi's arms were covered in burns—his own flames turned against him during one of the exercises. Even Shigaraki, who usually prided himself on his resilience, looked ready to collapse.

But I wasn't done.

"Final phase," I announced, clapping my hands. "Combat drills. Pair up."

The groans were almost deafening, but they obeyed, pairing off reluctantly. I walked between them as they fought, shouting corrections and criticisms at every mistake.

"Toga, stop hesitating! If you're going to attack, commit to it! You think your enemies are going to wait for you to make up your mind?"

"Dabi, control those flames! You're wasting energy. Precision, not brute force."

"Shigaraki, stop relying on Decay. Use your brain for once."

The session ended with all of them sprawled across the floor, too exhausted to even glare at me. I stood over them, arms crossed, my expression cold and unyielding.

"This is just the beginning," I said, my voice cutting through the silence. "You're weak. All of you. And if you think this is bad, you're not ready for what's coming."

Toga groaned, covering her face with her hands. "You're a demon, Izuku."

"Flattery will get you nowhere," I replied, smirking.

Dabi managed to lift his head, glaring at me through sweat-soaked hair. "You're insane."

"Maybe," I said with a shrug. "But you'll thank me later."

Shigaraki, surprisingly, didn't say anything. He just lay there, staring at the ceiling, his expression unreadable. But I caught the faintest hint of a smirk tugging at his lips.

They might hate me now, but I knew they'd come around. This wasn't just about pushing them to their limits—it was about breaking them down and rebuilding them into something stronger. Something unstoppable.

As I left the gym, I heard Dabi mutter under his breath, "I swear, one day I'm going to kill that guy."

I smirked to myself. "Not if I kill you first," I thought, amused.
