What happens if a hero saves one world… but dooms another?
Is he still a hero, or just a survivor of his own choices?

It’s been a long time since humanity learned to endure behind its walls.
Every nation built its fortress, every city its little lie of safety.
Yūsha Kurayami has watched even hope itself wear thin with time.
Saving a world that insists on destroying itself no longer seems to matter—
until someone takes away what he treasures most.

From that moment, the fight is no longer heroic.
It becomes personal.
And perhaps, in the end, that’s what truly defines a hero.
