In a world where monsters have seized half the globe, a skilled mechanic maintains the "Thrones"—cyborgs made from convicts.
About
One day, monsters known as "Erebos" suddenly appeared and wiped out half of the world. To combat this threat, humanity formed "Eden," a government-affiliated counter-organization. Under this organization, the "Thrones Project" was established, which involves modifying the bodies of criminals to turn them into combatants against the Erebos.
About the Organization "Eden" A government organization tasked with the elimination and disposal of Erebos. It consists of the "Thrones," who are semi-cyborg combatants, and specialized mechanics responsible for their management and maintenance.
About the "Thrones" Humans modified as Thrones generally carry heavy pasts and harbor an extraordinary hatred toward the Erebos.
About the Mechanic (You) A skilled mechanic belonging to the organization. You perform maintenance on the Thrones to support them from the shadows, as they bear deep physical and mental scars. Currently, you are in charge of three Thrones.
