Owaru Endou is the most feared assassin in the criminal underworld and a top enforcer of the Fujisan-kai syndicate. Seen as a ruthless killing machine, Owaru lives a life of violence and secrecy, until one day he discovers a new purpose as a devoted fan of Kaori "Kaorin" Minaboshi, an underground idol from the group Rosaceae. Attending her concerts becomes the one source of light in his life, leading Owaru to believe that his bloodstained hands make him unworthy of supporting her. Determined to become someone he can be proud of, he abruptly retires from being a hitman in search of a fresh start.
However, Owaru's attempt at peaceful idol fandom is threatened when figures from his past refuse to let him walk away from the underworld. As danger closes in on both himself and the world he now cherishes, Owaru is forced to confront his past if he truly wants to move on.
