"Find Princess Kaguya's Treasure" note with the English title of "Heroes and Vixens". Released by Geneon in 2005 on Volume 8: Sweet Betrayals.
Lupin and Fujiko are enjoying their time off driving by the seaside in Monaco when suddenly their trip is spoiled by a mysterious masked driver who challenges the duo to race him: if Lupin wins, he gets a generous amount of money, but if he loses then he has to help the challenger gets something he wants. Lupin accepts, but an out-of-control truck causes him to crash, losing the race. The other challenger steps out of the car and removes the helmet, revealing herself as a beautiful girl who calls herself Kaguya. The mysterious beauty asks Lupin for a seemingly impossible task: bring her the tears of a Snowman from Himalaya, in ten days. Nevertheless, Lupin is smitten with Kaguya and agrees, while Fujiko becomes highly suspicious.
Later, in a casino, Jigen is on a winning streak when suddenly a beautiful woman challenges him to a game of poker, with the same stake she made with Lupin before. Again, Jigen loses and has to get another impossible item for her: the scale of a mermaid from the Mediterranean Sea. Reluctantly, Jigen agrees, while Fujiko spies on the duo. Later that night, on the beach, Goemon is meditating on a rock when he sees a girl (again, Kaguya wearing a different attire) chased by two thugs. The samurai rescue the girl, who tells him that those men are holding her mother hostage and have asked a piece of liver from a living Kun Lun Dragon. Moved by her situation, Goemon promise to look for the liver, while Fujiko, hidden nearby, spies on them. The following day the three thieves start their separate journeys, without mentioning their real intentions to each other. Meanwhile, Kaguya is seen driving through a forest to a castle bearing the crest of the Phoenix Empire, while Fujiko follows suit: inside the castle, she sees Kaguya talking to an old witch, brewing a special potion made from flower pollen and still requiring three more ingredients, specifically the ones Kaguya asked for to Lupin and his partners.
While Fujiko informs Zenigata about Lupin’s whereabouts, Jigen, after a bad encounter with a giant octopus, manages to get a scale from a real mermaid, while Goemon, faced by a real Dragon, manages to slip into his belly and obtain a chunk of his liver. In the Himalayan wilderness, Lupin successfully meets a Yeti and manages to get some of his tears, getting buried in an avalanche as a result. Back in Monaco, Jigen and Goemon give the requested ingredients to Kaguya, only to meet each other shortly after and realizing that they have worked for the same woman, but are soon arrested by Zenigata. Lupin is still missing, but eventually he too arrives, still frozen in a block of ice, with his guide driving the car and delivering the frozen tears to Kaguya.
The frozen Lupin is soon taken in to custody due to Fujiko’s betrayal, but Jigen and Goemon manage to come up with an escape plan, taking the frozen Lupin with them, so that they can unfreeze him and find out that Kaguya used all of them. In her castle, Princess Kaguya sees her potion complete thanks to the three ingredients, but the old witch reveals herself as Fujiko in disguise and makes off with the potion. Soon enough Lupin and company arrive and confront Kaguya, who reveals the truth: her fiancé, a prince, was put to sleep by a curse, and the only antidote was that potion that the old witch was concocting with flower pollen and the three ingredients, but now that Fujiko has stolen the potion she has lost any hope. Moved, Lupin decide to forgive Kaguya and recover the potion from Fujiko who, unwisely, has sipped some of the brew, thinking that it would make her even more beautiful. With the recovered potion, the prince awakens from his slumber and Kaguya can get her happy ending, while both Jigen and Goemon want revenge on Fujiko, but it soon turns out that she already got her comeuppance, since the potion makes her hyperactive and unable to sleep at all. Two days later, Fujiko is still suffering the effects of the potion in the middle of the night, even begging Lupin to spend time with her. He tiredly tells her to go to sleep as it's three in the morning. She then resorts to finding a tired Zenigata outside and making him play janken with her.
