Professor Agasa gets taken, and suddenly the Detective Boys are solving the actual mystery instead of watching Conan do it. You're racing through the city following real clues, not waiting for exposition. The stakes feel different when the man who built the watch and created the gadgets is the one you're trying to save.
Professor Agasa vanishes without a trace, leaving behind only cryptic clues scattered throughout his laboratory and across the city. Conan and the Detective Boys find themselves facing an unexpected challenge: their beloved mentor and gadget supplier has orchestrated his own disappearance as an elaborate puzzle designed specifically for them. With nothing but riddles, hidden messages, and carefully planted evidence, the group must piece together Agasa's location before time runs out. Each discovery leads to another mystery, forcing them to think creatively and work together in ways they haven't before. The race against the clock becomes personal as they realize this isn't just another case to solve, but a test of their detective skills and their bond with someone who has always been their greatest ally. Every clue matters, every detail counts, and the Professor's safety depends on whether his students can prove they've learned everything he's taught them.
