If you loved Zatch Bell! Attack of Mechavulcan, try Bungo Stray Dogs: Dead Apple
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 Takuya Igarashi, and they both carry the foreign gem mood tag, and they sit in Action / Animation territory. If that's the register that drew you to Zatch Bell! Attack of Mechavulcan, the second film will land in a comparable space — through a different lens.
What Bungo Stray Dogs: Dead Apple is
Late March, Yokohama. The sky bleeds violet. A fog rises from the bay, folds in on itself, and the ability users inside it begin to vanish without a trace. Fog thickens into a city hungry for the next disappearance. In the style of late-era Satoshi Kon: paranoia distilled into animated geometry, where even rain feels like evidence.
