What if saving the world from a final boss meant becoming her ultimate downfall? Reborn into the wildly popular otome game, Celestia Kingdom, Arcs initially believes he's just a forgettable background character. His world is flipped when he discovers he's actually the childhood friend of the game's terrifying final boss! Desperate to prevent the catastrophic bad ending, Arcs dedicates himself to serving her daily, hoping to guide her away from a path of darkness. Yet, an ironic and shocking truth emerges: the very cause of her descent into villainy isn't some external force, but her devoted childhood friend, Arcs, himself! Prepare for an unpredictable and thrilling saga of master and servant, where a slightly (or more than slightly) yandere heroine grapples with her obliviously overpowered protagonist, Arcs, amidst a vibrant fantasy setting filled with action, drama, and unexpected romance.
