Security camera footage shows an unarmed man with shaven head, able to seemingly kill people with a simple touch. Police investigation leads to the suspected identity of the murderer: middle-aged man named Tarō Yamada. When the police conduct a search of his apartment, they find the rotting corpse of a woman. Adapted from Sato Jiro's own debut manga.
