“Noob. Weakest. Hardstuck .Tryhard. Trash. Pick a word, it fits me.”In a post-apocalyptic world overrun by monstrous creatures known as Eaters, some humans give up their humanity to gain a powerful weapon fused into their right hand. These people become Eater Blades, warriors who must hunt and feed their weapons with Eaters to rise through the ranks and prove their worth.In a world where rank means everything, Johnquis remains unranked.Why? Because his weapon is a chain. Everyone laughs, calling him “Leash Boy.” They mock him, never realizing the truth. That his chains aren’t made to cut… they’re made to control.This is a world where zombie-like monsters evolve, and a strange game-like system controls everything.Grind, rank up and evolve.Watch how Johnquis changes the game and tames the apocalypse.

Living life in this new world was already hard enough....So why?Why is the villainess of this world obsessed with me?

He would survive, even if it meant being something he sneered at in his previous life.A [Farmer].Of course, when did anything go according to plan? Never.
