It is not known which of the twins is which, who is Inmu and who is Yanku since they never talk even once during the whole movie. It is guessed that Inmu is the one wearing the red clothing.
He and his twin brother sport the creepy looking half gray and half white fox masks. Both of them seem to have a dark feeling to them with the way they acted. They run into the Abura-Tori (Oil-Taker) demons and spend most of their time in the movie running from the demons.
They are captured together by the Abura-Tori (Oil-Taker) demons and are the fourth and fifth kids to be captured.
Both Inmu and Yanku seem to have a strong sense of smell and are very fast runners.
