Shin Lupin Sansei (1977)

Blurb:
Monkey Punch’s classic super-spy, Lupin III, returns in an all-new series of action, adventure and intrigue. When the old gang gets invited to a soiree on a remote island, the reunion turns out to be anything but happy, and the situation downright explosive. Our Master Thief invades the HQ of his latest opponent, only to find that the reclusive 'he' is actually a 'she' with a secret weapon that leaves Lupin rock-hard. A big diamond, a bitter old man and a bevy of lovely ladies add up to nothing but danger for the devil-may-care Lupin ... and that’s just how he likes it. Lupin takes on his most dangerous mission yet -- he must break into a high security prison and steal a devious device designed to drop him right back into the dungeon, resulting in the most destructive denouement to date. When Lupin and his nefarious crew train a beautiful young woman in the ways of self-defense, only to use the inside info against her, things get just a little too hairy ... or should we say hair-less?
