At the awakening ceremony, my SSS-class familiar, which I obtained despite my ordinary background, was stolen through betrayal. By chance, I activated the Multi-Return Familiar System. I purchased the dying Frost Queen Ashe and forged a contract with her. Empowered by the system, I led Ashe to grow stronger, crushing opponents one after another in secret realm trials and academy tournaments. Later, I joined the guard unit. Together with Ashe and my familiar Bruce, I delved into dangerous secret realms to investigate the Serres family’s void conspiracy. Facing the void shadows about to break through the boundary, I embarked on a perilous final battle to defend the Federation’s border.
