Two bizarre murders attracted the attention of the police: one was the death of a young girl in a locked bedroom, which appeared to be suicide, and the other was a secret case in which a wife saw her husband raise a knife in his sleep. Both of the dead had received a call from "0" (Takamoto Jin was also acted the role of), which made the Fushima police officer (Gugu Renmei) who took over the case firmly believe that there was a big secret inside. Fog Island asks for the help of Nightmare Detective Yinguma (Matsuda Ryuhei), who has the magical power to enter other people's dreams. Shadow Marsh was so distressed by this special power that he saw all the evils of the human heart, the dangers of the world, and had no illusions about good things. When a police officer was in danger after contacting "0", Shadow Marsh finally agreed to intervene in the investigation. Shadowbog put on his black cloak and formally confronted "0". When this "0" experience and fate gradually unveiled the mystery, people's emptiness and loss of the world are also spreading rapidly. It turns out that there is a black hole in everyone's heart.
