If you loved GARO and the Wailing Dragon, try GARO - Kiba: The Dark Knight
A bridge between a film you've already seen and one most people haven't. 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 Keita Amemiya, and they both carry the surreal mood tag, and they sit in Action / Adventure / Fantasy territory. If that's the register that drew you to GARO and the Wailing Dragon, the second film will land in a comparable space — through a different lens.

What GARO - Kiba: The Dark Knight is
You inherit Kiba’s armor, a black relic pulsing with absorbed horrors. Then the cape unfurls, alive. The director leaves the ghost inside the metal visible in every bead of sweat on the host’s skin.
