What they share
Both films are directed by Kinji Fukasaku, and they both carry the dread, late night mood tags, and they sit in Horror territory. If that's the register that drew you to The Green Slime, the second film will land in a comparable space — through a different lens.

What Crest of Betrayal is
Snowflakes fall on lacquered swords, a lone shamisen plays, in feudal Japan's winter. Shadows of loyalty and deceit entwine. Fukasaku's lens touches dark fantasy.
