K-20: The Fiend with Twenty Faces
What they share
Both films are directed by Shimako Sato. If that's the register that drew you to Eko Eko Azarak: Wizard of Darkness, the second film will land in a comparable space — through a different lens.
What K-20: The Fiend with Twenty Faces is
You wake in 1949 Teito wearing a circus leotard and wake again in a police cell. Fingerprints from the phantom thief K-20 brand you the culprit. A duchess and her fiancé detective drag you back into the thief’s final heist. The camera lingers on 1949 Tokyo’s neon shimmer, spinning like the stolen watch.
