Lupin the 3rd: The Secret of Twilight Gemini(1996)

Lupin III: "Twilight☆Gemini no Himitsu"

The Twilight diamond's rock-solid secret is about to be cracked.

As Lupin's mentor Don Dolune Lies on his deathbed, he hands the master thief a gift: the diamond named Twilight. But it's only half of the treasure-the other half of the Twilight can be found in Morocco. But it's not as simple as "X marks the spot" when a civil uprising is broiling between two factions in this desert paradise. Lupin must contend with his sometimes-partner Fujiko, his feelings for the gorgeous brunette Lara, and on top of it all, the relentless whip-wielding maniac Sadachiyo.
