"Abyss Continent" - a forgotten "bottom" alien continent with few resources and chaotic laws. The sky is shrouded in thick dust clouds, sunlight is scarce, and it is filled with dangerous mutant creatures, treacherous environments, and refugees struggling to survive. This is where the upper world dumps its "garbage". The "Hand of the Pure World" is a powerful organization that maintains "order" in the chaos of the mainland. It possesses technology and secret methods that surpass the locals, but it secretly conducts inhumane and taboo human experiments... An experimental subject who escaped by chance, in order to fight against the "Hand of the Pure World" organization, used a fire as weak as an ash fire to burn down everything.
