In a world where thousands of individuals are isekai’d into a deadly, ever-shifting survival game, Kagetsuki Rin—a cold, emotionless genius—is thrust into the chaos alongside brilliant strategists, lucky fools, and ruthless opportunists. With each stage presenting increasingly complex rules and mind-bending challenges, only one player can ascend to claim ultimate power. While others scramble for alliances and survival, Rin calmly dismantles their schemes with her unmatched intellect, unraveling the hidden motives of the gods who orchestrate the game. But as the stakes rise and the line between ally and enemy blurs, Rin begins to question if winning means more than simply outsmarting everyone—if it means redefining what it means to play the game at all.
