Dakara Watashi wa Korosu koto ni shita

Shu Iwata is a university student drifting through an unremarkable existence. He devotes little energy to his academics or personal ambitions, preferring instead to find comfort in his devotion to his favorite idol, ANNA. Surrounded by good friends and free of any major grievances, his life seems perfectly stable—save for one lingering shadow: the unresolved disappearance of his older sister. His quiet routine is disrupted when he crosses paths with Yuki Minowa, a woman who bears an uncanny resemblance to ANNA. Although her appearance is nearly identical to the beloved idol, her voice marks her as someone entirely different. Even Shu, who has never shown any interest in romance, finds himself inexplicably drawn to Yuki because of that striking familiarity. Yet, beneath this budding fascination lies a hidden truth. Shu remains completely oblivious to the fact that the woman standing before him is not a stranger at all, but rather someone he knows intimately.
