What they share
Both films are directed by Hiroyuki Yano, and they both carry the neon soaked mood tag, and they sit in Action / Animation / Crime / Drama territory. If that's the register that drew you to Lupin the Third: Dead or Alive, the second film will land in a comparable space — through a different lens.

What Lupin the Third: Island of Assassins is
You're framed for a murder you didn't commit. But the real killer has a familiar gun. Tracking him leads straight to an island of assassins. All want you dead. The animation recalls a vintage paperback cover. It doesn't let you off easy.
