Countdown to Death: I Rely on Rules to Purge My Revenge

My father was attacked by a bear, leaving a strange blue-gray paw print on his wrist. Seven days later, he died. Shunsuke Sudo discovered that this palm print was no accident - the officials who killed his father also had the same mark on their hands. As for policeman Seiichi Nakamura, he looked at him like he was looking at prey. By chance, Shunsuke puts on his ancestral bear skin and enters a gray world called "Satoyama". There is a wall there, and three iron rules are engraved on the wall: He who kills is killed by a bear. Anyone who lies will encounter a bear within three days. Defaulters have their families attacked by bears. From now on, everyone who deserves death will see his own judgment before death. But what Shunsuke doesn't know is that when the mantis stalks the cicada, the oriole follows behind. Nakamura is using his own method to tighten the hunting net step by step. When rules become weapons, who is the real hunter?
