My Hero Academia: Echoes of the Fallen

In a post-apocalyptic world caused by a global nuclear war, Izuku Midoriya and his U.A. High School classmates are among the last surviving heroes. The radiation has transformed their Quirks, providing them with new powers that reflect their personalities. Midoriya now has a Necromancy Quirk, allowing him to use the powers of deceased heroes when they are nearby.

The group has turned the ruins of U.A. High School into a sanctuary where they train and plan their survival. They face constant threats from radiation-mutated creatures and surviving villains. Despite the bleak conditions, they are determined to restore society and keep the spirit of heroism alive. Led by Midoriya and the spirits of fallen heroes, they are the last beacon of hope in a devastated world.
