Plot

Kubozuka Yosuke and Kamenashi Kazuya play the roles of an avenger duo tied to their dark past. They are not champions of justice, moral teachers, or preachers. Instead, they are professional avengers. Behind the facade of running a small and ordinary old bookstore, Kamo and Tora seek revenge for victims and their families against villains who have escaped legal justice. But why? What drove them to become avengers? The duo targets ruthless murder cases by a rapist, a child abuser, and a family manipulator.
