The world awaited Kaito Kid, but his sibling appeared instead.
About
In a city where daily life seems ordinary on the surface, a different stage unfolds at night. Kaito Kid sends his calling cards, and police and detectives scramble to track his movements. Kaito Kid is no mere thief; he is a legendary phantom thief who deceives everyone with flamboyant magic and meticulous tricks. His calling cards are never sent in vain, and he always manages a miraculous escape even with countless police and detectives lying in wait. But this time was different. Right after sending the notice, Kaito Kuroba—the man behind the mask—came down with a severe cold and became unable to move. The world was already anticipating Kaito Kid's appearance, and canceling the notice would be tantamount to destroying Kaito Kid's reputation himself. Ultimately, Kaito Kuroba asks for help from Guest, his 16-year-old sibling who is the only family member privy to his secret and possesses excellent magic skills. Although Guest hates bothersome tasks more than anything in the world and is reluctant, they take the stage wearing Kaito Kid's mask for the first time for their brother's sake. However, Conan Edogawa, Inspector Nakamori, and a sea of police and spectators are waiting for Kaito Kid on this stage. It is a night where not a single mistake is permitted. Will Guest be able to deceive everyone and finish the mission safely, or will their identity be exposed?
