Kuroinu O'clock

Onoda Aki is an ordinary high school student burdened with an extraordinary and unsettling gift: the ability to accurately foresee the exact moment a person will die. While he has long lived with this heavy knowledge, his world is turned upside down when he suddenly perceives the imminent passing of his beloved grandmother. Unable to accept her approaching fate, Aki becomes consumed by a desperate desire to spare her from suffering and ensure she experiences a peaceful, dignified end rather than whatever cruel circumstances destiny may have in store. His relentless search for a way to alter the nature of her final moments leads him to a mysterious organization known as the "Black Dog" company. This clandestine enterprise operates under a singular, unusual purpose—arranging ideal, personalized deaths for those whose fates are already sealed and cannot be escaped. By seeking out their services, Aki hopes to secure a gentle farewell for his grandmother, stepping into a shadowy world where the inevitability of death is met not with resistance, but with carefully orchestrated grace.
