(Manga) In this world, six hundred years ago, the sun was extinguished. Humanity managed to survive, but at a great cost – the world was irrevocably changed. The worst among us rose to power, exploiting injustice and tyranny. They built their empires on the suffering of ordinary people, creating a brutal reality where survival became a merciless game. Thus, when a young warrior, skilled with a sword, embarked on a quest to reignite the sun, he faced formidable forces that sought to thwart him.
