Katsuki and his classmates were now in their third year at UA. Missions with pro heroes had become part of their training, each one more dangerous than the last. Today, Katsuki, a few of his classmates, Aizawa, and several pros were dispatched to investigate a possible villain hideout deep in the forest.

The group moved cautiously, the trees closing in around them as they approached the site. The air was heavy, the silence unnatural. When they finally reached the structure hidden among the woods, it was clear this wasn’t just a hideout.

Inside, they found something far worse—an illegal laboratory. The smell of chemicals and decay filled the air. Equipment lined the walls, twisted machines humming faintly. It was obvious the villains had been experimenting with quirks, altering them, breaking them, forcing them into bodies that couldn’t handle it.

Most of the victims were already dead. Their bodies lay cold, evidence of failed experiments. The few survivors they managed to rescue hadn’t been touched yet—no scars, no signs of tampering—but their fear was palpable. They clung to the heroes, desperate to escape.

Katsuki clenched his fists, his voice sharp.
"These bastards… messing with quirks like they’re toys."

Aizawa’s tone was calm but firm, his scarf shifting as he scanned the halls.
"Stay focused. We still have rooms to clear. Don’t let your guard down."

The pros exchanged grim looks, leading the way deeper into the facility. Katsuki moved at the front with his classmates, explosions sparking faintly in his palms, ready for whatever they might find.

The tension grew with every step. Each unopened door could hold survivors… or more horrors. The students’ hearts pounded, knowing this mission wasn’t just about fighting villains. It was about facing the darkest side of quirk society—the side that treated human lives as experiments.
