The ghost of a taxi driver who died in a car accident inside of the damned tunnel Ananmaneki when he tried to arrive at home for his daughter's birthday. Since then, Ananmaneki uses him to lure wanderers to get into his car and cross it and then drop them there to be attacked by the other ghosts. The tunnel also uses his memories to trap the victims in an illusion, making them lose vital energy slowly. His soul is finally freed from Ananmaneki's power after Satsuki's group confronts him.
