Onechanbara: Bikini Samurai Squad
What they share
Both films are directed by Yôhei Fukuda, and they sit in Horror territory. If that's the register that drew you to Death Tube: Broadcast Murder Show, the second film will land in a comparable space — through a different lens.
What Onechanbara: Bikini Samurai Squad is
Ruined Tokyo, sometime this century. Rotting flesh and a high, keening giggle. Aya hunts her father's killer, her blade the only thing between her and a zombie horde, her bikini somehow staying on. Peak mid-aughts J-horror knows its audience.
