If you loved Lupin the Third: Seven Days Rhapsody, try Lupin the Third vs. Detective Conan
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.

Lupin the Third: Seven Days Rhapsody

Lupin the Third vs. Detective Conan
What they share
Both films are directed by Hajime Kamegaki, and they both carry the neon soaked, outsider, playful mood tags, and they sit in Action / Animation / Comedy / Crime / TV Movie territory. If that's the register that drew you to Lupin the Third: Seven Days Rhapsody, the second film will land in a comparable space — through a different lens.
What Lupin the Third vs. Detective Conan is
A pair of thieves and a tiny sleuth race to solve the same mystery in a cross-franchise cameo reel. Conan Edogawa investigates a suspicious hunting accident while Lupin the Third plots to swipe an ornate royal crown. The collision feels less like a crossover and more like a theme-park stunt ride.
