Blind Beast vs Killer Dwarf

Japanese movie with a REALLY disjoint plot. A guy sees a dwarf walking with a human arm one nights and investigates. A second plot involves a blind and hairy masseuse who captures women and makes them his sex slaves. The dwarf got his start after he joined a circus and got made fun of – so he burns down the dormitory with all the other performers inside. A private investigator is looking for some of the missing women.
