Lupin the Third: The Woman Called Fujiko Mine
What happened when Lupin III met Fujiko Mine for the first time?
She’s a thief. A killer. A saint and a scandal. She’s whatever you need her to be to get the job done. She takes your breath away to get what she wants. She takes everything else just because she can. It’s all in a night’s work for the woman called Fujiko Mine. She’s the slinky, sultry thread that holds Lupin III’s crew together—and this is the heist that started it all.
