LUPIN THE 3RD: THE SECRET OF TWILIGHT GEMINI

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.
