Akiyo Oshima lived a life of privilege—wealthy, respected, and seemingly untouchable. His fatal mistake was succumbing to betrayal, awakening the fury of an entity he never imagined existed: his girlfriend Sayuri, who embodied Death itself. Sayuri's curse stripped him of everything. His identity dissolved. His body transformed. His gender shifted. Each reincarnation grants him a new vessel and fractured memories alongside random personality traits. Now he exists as Shizune Accursed, cursed to traverse countless worlds with no agency over his destiny. In every realm Shizune enters, an obsessive presence awaits—a Yandere whose twisted devotion becomes an inescapable death sentence. Their love manifests as possessive madness, suffocating obsession, or violent need. Death comes repeatedly, each time by the hands of someone who claims to cherish her completely. Cycle after cycle, Shizune perishes in the arms of those whose passion transforms into destruction. Desperate to comprehend the weight of manipulating others' affections, Shizune ventures deeper into dangerous territory. Can she decipher the curse's mechanics and reclaim her freedom? Or does eternity await—an endless loop where love breeds only death? From fantasy realms to distant futures to contemporary settings, one truth persists: distinguishing allies from enemies becomes impossible. Behind every kind gesture lurks potential betrayal. Among strangers, companions, and blood relatives, Shizune must identify those worthy of trust before another cycle claims her life. In a world where yanderes hide in plain sight, survival demands more than luck—it demands understanding the hearts of those around her.
