Hajime leads an unremarkable life as an undertaker, but he likes his job and has no reason to complain. Nor can he complain of being always called "onii-san" by one of the top star actresses in the country, Kidō Kotone, a childhood friend. Their relationship has always had a touch of awkwardness due to the parents of both having died violent deaths, but nothing could have prepared Hajime - or Japan - to the deed Kotone decides to perpetrate seemingly out of the blue.
