If you loved The Files of Young Kindaichi: Legend of the Shanghai Mermaid, try SPEC: Zero
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.

The Files of Young Kindaichi: Legend of the Shanghai Mermaid

SPEC: Zero
What they share
Both films are directed by Yukihiko Tsutsumi, and they both carry the cerebral, foreign gem, mindfuck mood tags, and they sit in Drama territory. If that's the register that drew you to The Files of Young Kindaichi: Legend of the Shanghai Mermaid, the second film will land in a comparable space — through a different lens.
What SPEC: Zero is
The public security bureau in summer. A missing report lands on a new detective’s desk. Her parents died in the same crash. The only thing left is the detective who whispered one word: spec. Kurosawa’s Rashomon-esque sibling rivalry, but played like a crisp manga episode.
