This is the Lupin special that takes the annual heist formula, kicks it off a boat, and buries it under the sea floor at Kiritappu. It opens exactly the way it should: Fujiko dangles a lead, Lupin and Jigen do the actual filthy work of dredging the ocean bottom for it, and the payoff is a treasure that supposedly cracks time itself open. Then Kyousuke Mamoh flings the whole gang centuries into the past, and the best part is that Zenigata goes with them, jurisdiction gone, dignity gone, still bellowing Lupin's name at a man who no longer exists in this century. Two feuding tribes, one lost treasure, and a thief who cons people the same way whether he's in a jacket or in period clothes. That's the joke Lupin specials keep landing. Change the era, the man doesn't change.
Lupin receives a tip about a sunken fortune hidden beneath the waters of Kiritappu, one rumored to contain the secret to manipulating time itself. The heist goes sideways when a mysterious man named Kyousuke Mamoh intercepts them, sending Lupin, Jigen, Goemon, and Fujiko spinning backward through centuries. Inspector Zenigata tumbles in after them, equally stranded. Now stuck in feudal Japan, the crew finds themselves caught between two hostile clans while Mamoh hunts them with a sinister purpose: he plans to erase Fujiko from existence by eliminating her ancestor before she's even born. Time isn't just the setting here, it's a weapon pointed at their throats. Lupin has always thrived on impossible odds, but this job demands more than cunning and quick hands. He needs to uncover what the ancient treasure actually is, outsmart a villain playing by rules that bend reality itself, and somehow return home before his partner vanishes from history altogether. Every moment counts when your enemy controls when you exist.
