Lupin the IIIRD: The Movie - The Immortal Bloodline (2026) Plot Summary Explained

Muom orchestrates the attacks on Lupin to manipulate history from behind the scenes. As an ancient immortal born from blood, he has been secretly controlling events on the island for centuries. The invitation to the uncharted island was a trap designed to draw Lupin there, where Muom could eliminate him and prevent any interference with his long-term plans.

Foreshadowing: The initial attack on Lupin's hideout that destroys his treasure collection was engineered to surface the map fragment leading to the island.

Lupin discovers that Muom has become the island itself, literally sustained by rivers of blood flowing through the island's circulatory system. By severing these blood conduits, Lupin weakens Muom and the island itself, causing the blood-red waters to carry him away. This removes Muom's source of power and allows the island to collapse.

Foreshadowing: Muom reveals he is an ancient immortal born from blood when Lupin infiltrates his stronghold.

Muom's power stabilizes the island, and when Lupin lures him into a massive explosion, Muom regenerates and retaliates by triggering the island's volcano into eruption. A massive tsunami blocks the shoreline simultaneously. These catastrophic events create the final chaotic backdrop as the characters race to escape the collapsing island.

The post-credits scene shows Lupin's grave destroyed and his missing cigarettes returned to Jigen, with Zenigata learning that Lupin has supposedly been arrested.
