As Lupin's mentor Don Dolune lies on his deathbed, he hands the master thief a gift, the diamond named Twilight. Though it's only half the treasure — the other half of the Twilight can be found in Morocco. Lupin must contend with his on-again-off-again-partner Fujiko, his feelings for the mysterious Lara, and the relentless whip-wielding maniac Sadachiyo in order to bring Twilight back to its full glory.
