Saikou no Jinsei no Owarikata - Ending Planner

Ihara Masato becomes the fifth-generation owner of a funeral parlor after his father dies and he takes over the family business which he has always hated. As a purveyor of the police, all this funeral parlor handles are “imperfect” dead bodies. Masato ends up facing these silent dead bodies, which have died of various causes, and the harsh reality of the world, together with a rookie detective Sakamaki Yuki whom he and his siblings have become acquainted in an unexpected way. On occasions when the police dismiss dead bodies as just accidental deaths, Masato tries to find out the truth for the sake of the surviving family even though he knows that he is being meddlesome. As he does so, he starts to face up to his own lifestyle and family.
