Conan and Ran are visiting Heiji and Kazuha in Osaka when the four come across a trio of kids while touring the city. These children, who look eerily similar to the Detective Boys but with different personalities, are looking for their friend who has gone missing—and the two young detectives agree to help find the vanished boy.

Conan Edogawa and the rest of the gang are invited to Inspector Ninzaburou Shiratori's villa for a small gathering. The party's highlight is Shiratori's prized wine collection—including his most expensive vintage—and a bottle from it will be served for the evening. However, just as this wine is to be brought out, Shiratori finds the bottle smashed on the floor—and the culprit can only be among the 16 people present in the gathering.

Mitsuhiko Tsuburaya lends Conan Edogawa a massive amount of manga, which Conan starts reading, despite the overwhelming quantity. Elsewhere, Kogorou Mouri is asked by the Mine family to protect the treasured sword in their dojo, as Kaitou Kid has sent a note of his intent to steal it. Upon arriving at the dojo, Conan and the others meet Yaiba Kurogane. Together, they aim to thwart the phantom thief's plans. However, Conan begins to notice something strange about the case...

While walking through the streets of Tokyo, Linn Suzuki comes across a strange device sticking up from the sidewalk. Suddenly, she is set upon by thugs and is helped by a beautiful stranger who takes them all down. It seems young Linn has fled Deep Kyoto from her cruel mistress and has traveled to Edo where she hopes to find her long lost brother, who was last seen working for the Kuon Detective Agency. By chance, this stranger happens to be Miho Kuon and lets Linn stay with her (nicknaming her Kotetsu, or Little Tetsu after her brother, Tetsujin). However, a mysterious agency called the Syndicate are after Miho and Linn is now in the thick of things. (Source: ANN)
