Dark Dragon protests his defeat to Diamond Ryugu that the Dino Daggers were the only reason he was defeated, so a trap is developed. Kaito meets up with a girl named Kira who is "lost" and tries to steal Kaito's Dino Dagger. She then tries to use one of Dark Dragon's bats to shapeshift into the Dino Dagger so she can swipe the authentic one. Rena tries to warn Kaito, but it's too late. Kaito must get his dagger back or it's all over.
