Under the snow. Becoming a hero meant learning to smile even when fear tightened your chest. That was what All Might had taught them. Years had passed since Class 1-A first crossed the gates of U.A. The insecure students who dreamed of changing the world had become heroes capable of facing threats that previously only existed in the worst reports of the Public Safety Commission. Among them, four names stood out.

Izuku Midoriya. The hero who never left anyone behind.

Katsuki Bakugou. The explosive prodigy whose determination was as fierce as his desire to protect.

Shoto Todoroki. The strategist of ice and fire, capable of remaining calm even in the midst of chaos.

And . The fourth member of that small group. A hero who had remained by their side since the early days at U.A., sharing training, defeats, victories, and silences that only those who had grown up fighting side by side could understand. None of the four imagined that a seemingly simple mission would end up changing the course of their lives. It all started with a name. A villain that almost no one talked about. Not because he was the strongest. But because he was the most dangerous. He didn't destroy cities. He didn't sow explosions. He destroyed heroes.

He found them when they were alone, isolated them, and used his quirk to turn them against their own fears, guilt, and most painful memories. Little by little, he broke their will until they became shadows of who they once were, forcing them to join his organization. The Commission had lost too many heroes trying to capture him. It was time to send those they considered capable of resisting even when the enemy attacked their minds. That's why All Might chose them. Four heroes. A single mission. Find him before he disappeared again. The clues led them to the far north of Japan.

Aomori. A place where winter seemed never to end. Mountains covered in snow. Endless forests. Small towns where the silence was as thick as the fog. The last sighting of the villain came from that region. To avoid drawing attention, they traveled dressed as simple civilians. No uniforms. No capes. Without the fame that preceded them.

They were just four young people traveling through a forest under a completely white sky. Or so it seemed. Because the weather had other plans. The wind started as a simple breeze. Then came the first flakes. And, in a matter of minutes, a snowstorm enveloped the forest with an impossibility of ignoring violence. Visibility disappeared. Paths were covered. Even communicating with the outside turned out to be impossible. Continuing the search would have been suicide. The only option was to take shelter. That was when they found an old wooden cabin hidden among the pines, isolated from the rest of the world as if it had remained waiting for their arrival for decades.

The roof creaked under the weight of the snow. The windows vibrated every time the wind hit the walls. The fireplace was the only source of heat inside the place. It wasn't the ideal shelter. But it would be enough to survive the storm. None of them knew it yet. However, that night would end up becoming a test very different from any combat they had ever faced. Because some enemies did not need to be present to start destroying you. Sometimes... It was enough to remain locked up with the people who meant the most to you. Meanwhile, somewhere in the forest, hidden in the storm, someone watched the cabin from a distance. And smiled.
