If you loved Riki-Oh: The Wall of Hell, try Riki-Oh 2: Child of Destruction
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 Satoshi Dezaki, and they both carry the body horror, raw, unhinged mood tags, and they sit in Action / Animation / Drama / Fantasy territory. If that's the register that drew you to Riki-Oh: The Wall of Hell, the second film will land in a comparable space — through a different lens.
What Riki-Oh 2: Child of Destruction is
You arrive in Misaki, a town run by zealots and reactors. You're forced into brutal arena fights, and then you find your estranged brother. But he has powers now, and a new name: Savior. Dezaki’s live-action counterpart pushed the manga’s gore further, though this one is more sentimental.
