Asano Kanamori

After escaping from an insane asylum, a medical student assumes the identity of a mysterious dead man, who appears to be his doppelganger, and gets lured to a sinister island ruled by a mad scientist and his malformed men.

Orphaned Kiku was raised at a Buddhist temple and learned theatrical arts and martial arts as a child, which were used to put on stage productions to raise money for the temple, but also to display young lads who were essentially for sale to the highest bidder. When Kiku gets fed up with how the temple uses the orphans and wants to leave he gets accused of a double murder and has to flee for his life and liberty.
