Ai Enma and her friends continue to give their vengeance service to those who have mistreated others, and the price is as high as ever—for sending the offender to hell, the one demanding vengeance is also condemned to the abyss. A new malevolent power is watching them as they send soul after soul into the darkness: a tiny girl named Kikuri. While doing her responsibilities, Ai encounters Takuma Kurebayashi, dubbed the "Devil's Child" due to the awful incidents that occur around him. Takuma's notoriety, however, prompts the locals to use him as a scapegoat for those who have been transported off to hell. When things suddenly spin out of control, Ai must find a way to put them back under control.
