Humanity faces extinction in a fractured dimension ruled by a Demon King. Zack "Kazz" Foreman, having failed to save them once, sacrifices his memories to reset the timeline for a second chance. Transported to a dangerous new world, Kazz rejects the overpowered "Hero System" offered by a voice in his head, instinctively knowing the easy path is a trap. Instead, he relies on a "Ranching System" to empower a team of outcast monster girls and masters Shamanic magic, determined to claw his way back to the Center of Everything and end the Demon King’s reign.
