A swordsman spoils what looks like a Kaito Kid diamond heist in Tokyo, and the thief under the mask turns out to be Lupin the 3rd, working under duress because Fujiko Mine is wearing an explosive collar. What he actually wants is the Cherry Sapphire, held by a man calling himself Alan Smithee. Conan Edogawa picks up the trail after spotting Daisuke Jigen in the entourage of Italian singer Emilio Baretti, and Inspector Zenigata is already on his way. This manga adapts the 2013 crossover film across two volumes.
