Now the stepbrother of the alluring Busujima Saeko, he's thrown into a world where survival demands sharp steel, quick reflexes, and… certain eye-catching distractions. But this isn't just another tale of surviving the zombie hordes. Daiki possesses a unique advantage: the Unreliable Choice System.

Yet, amidst the gore and the ever-present threat of becoming zombie chow, the story explores how a compassionate protagonist navigates unimaginable circumstances. Daiki's journey is one of adaptation, growth, and the forging of bonds in the most desperate of times. Can he maintain his humanity in a world gone mad, or will the darkness consume him? The answer may surprise you.
