The Empire of Corpses

In 19th century Europe, John H. Watson (Yoshimasa Hosoya), a medical student and aspiring corpse engineer, is scouted by the government to become a secret agent. He is tasked with finding and retrieving Frankenstein's original research on reanimating a corpse with a soul, believed to be in the possession of Russian corpse engineer Alexei Karamazov (voice). Accompanied by Captain Frederick Barnaby (Taiten Kusunoki) and guide Nikolai Krasotkin, Watson embarks on a perilous journey across various continents, encountering upgraded corpses capable of limited human-like intelligence.
