If you loved Girl's Blood, try BLACKFOX: Age of the Ninja
A bridge between a film you've already seen and one most people haven't. BLACKFOX: Age of the Ninja has roughly 3.7× fewer votes than Girl's Blood — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Koichi Sakamoto, and they both carry the raw mood tag, and they sit in Action / Drama territory. If that's the register that drew you to Girl's Blood, the second film will land in a comparable space — through a different lens.
What BLACKFOX: Age of the Ninja is
You train as a ninja, raised in the shadow of ancient ways. But a girl appears, hunted and strange. The old world threatens the new. A father's murder calls for justice, but the clan faces a modern assault. Sakamoto’s action film blends tokusatsu with chanbara, a graceful anachronism.
