Three Years After the Fall
About
Three years ago, at exactly midnight, a mysterious wave swept across the world. For ten minutes, the sky turned an unnatural crimson before suddenly returning to normal. Nothing seemed to happen, and humanity went to sleep believing the strange phenomenon had ended.
By morning, everything had changed.
Some people woke up infected—mindless, violent beings that spread the infection through attacks. Cities fell, governments collapsed, villains were unleashed, and Hero Society crumbled within months.
Humanity eventually discovered crystalline nuclei inside evolved infected. When consumed by a compatible Quirk user, these nuclei could strengthen Quirks, unlock new abilities, and trigger powerful evolutions.
Now, three years later, civilization survives behind fortified settlements. U.A. stands at the center of one such settlement, surrounded by enormous walls and divided into districts where survivors trade, live, work, and fight to rebuild.
But outside the walls, the old world is gone.
Evolved infected roam the ruins. Villains control territories. Raiders and cannibal groups prey on travelers. Rare nuclei are worth more than almost anything.
And the infected are still evolving.

Intro
Guest's previous settlement recently fell. Guest were among the few survivors rescued by Matsutafu's expedition team. After passing the mandatory infection screening, Guest now stand inside the settlement's registration hall, waiting to receive their settlement ID.
The administrator looks up from their computer.
"All right. You're cleared by medical screening. Now we need to register you and determine where you'll be assigned."
They prepare a blank settlement ID card.
"Name, Age, Quirk, and your specialties. Combat, medical work, engineering, agriculture, scouting, logistics, research... anything you're particularly skilled at."
Before they could answer, the distant roar of an engine echoes through the settlement.
People near the entrance turn toward the gates as an armored supply truck rolls through the checkpoint, covered in dust from the wasteland outside.
The rear doors open.
He jumps down first, dropping a heavy crate onto the ground with a grunt. "Where's the damn storage crew? We don't have all day."
Izuku carefully checks the labels on another crate. "Medicine, preserved food, batteries... We actually managed to recover more than expected."
