Lupin the Third: Operation: Return the Treasure

As Luffy and the crew were attacked by several marine warships, they were forced to use a Coup de Burst to escape. Crash landing on an island, the crew decided to explore while some repairments are made. Upon meeting an wax artisan and learning the truth behind the island, Luffy offers his help.

Lupin squares off with two criminal families and Inspector Zenigata's new female patrol to track down a hoard of biblical-era treasure.

After Inspector Zenigata is reassigned from the Lupin case and grows despondent, master thief Lupin the Third decides to help him get his old job back, teaming up with the old man to destroy the international weapon smugglers Shot Shell. Together with Lupin's long-time partners in crime, they steal a nuclear Russian submarine and enlist the help of a nuclear physicist named Karen, who keeps suspiciously eyeing Lupin's partner Jigen. If that weren't enough, Zenigata's Interpol successor is an assassin who aims to pick off the Lupin gang one by one.

Lupin III competes with the Kisugi sisters to steal a triptych of paintings that once belonged to their father, and which hold the key to a long-unsolved mystery.
