Lupin III: Twilight Gemini no Himitsu

An aging crime boss gives Lupin a strange diamond known as the Twilight Gemini, claiming it is one half of the key to a legendary treasure. The trail leads Lupin to Morocco, where the jewel is tied to the lost wealth and bloody history of the Gelt people.

There he crosses paths with Lara, a young woman connected to the secret, while assassins, criminals, and Inspector Zenigata close in. To uncover the treasure, Lupin must learn whom to trust before the Gemini's other half falls into the wrong hands.
