The Liver-Taker is the first demon we see if you don't count the demon mask possessed Sorincha. It carries a large wheel looking thing in its back with the help of four of it's six arms, its left arm is a wooden club, it stands on four legs.
He is awakened when Noshiga throws a stick at him and breaks one of the lights hanging from his wheel. He captures two of the kids which happen to be Suku and Tachiji, members of Noshiga's gang.
This demon was inspired for the movie from a Buddhist statue. He was made to look more human then the other demons.
