The Detective Boys are on their way to a camping trip with Agasa. On the way, they get a view of Mt. Fuji, the biggest mountain in Japan, and the newly constructed Nishitamashi Twin Tower Buildings, which are the tallest buildings in Japan. While looking outside, Mitsuhiko tells Agasa if they may pay a visit, and he agrees. They arrive at Auto Campgrounds where they finish eating rice bowls. Genta punishes Mitsuhiko for not finishing his rice, because the gods will punish him.

Nighttime comes and everyone is sleeping soundly in their tents except Genta and Haibara. Genta goes to the bathroom, and on the way back, he spots Haibara on the phone. Not suspecting anything, he runs back to the tent shivering. She talks to a mysterious person on the phone leaving her next location as the Twin Tower Buildings, and saying "he'll be there". Still nighttime, Gin and Vodka are seen in the Porsche 356A talking presumably to Haibara or perhaps listening in on her calls. They'll also be at the Nishitamashi towers.

On their way, Genta complains on not fitting in the back seat, forgetting he ate five bowls of rice for breakfast. Mitsuhiko decides to try and play the 30 seconds game. You count without looking at the timer, and whoever is closest to the time wins. Haibara and Agasa aren't going to play. Mitsuhiko goes first getting a time of 40 seconds, Conan gets closer with a time of 27 seconds, Genta counts 59 seconds, and Ayumi gets the perfect score of 30 seconds. Genta asks Haibara who she was talking to on the phone, and she replies he was dreaming. They finally come to the Nishitamashi Twin Tower Buildings, and not shortly after, Ran, Kogoro, and Sonoko arrive by taxi. Surprised, they decide to join each other as Kogoro's old friend from college, Mio Tokiwa, who owns the building. He was invited a week before the opening. Mio Tokiwa's secretary named Chinami Sawaguchi comes outside and greets them to take a quick tour of the building. She explains that all floors above 31st belong to the Tokiwa Corporation, and the showroom spans from the 2nd to the 3rd floor. Mitsuhiko explains to Ayumi that the Tokiwa Company deals with computer software, but are involved with everything concerning computers. At the game room, they meet the Tokiwa executive named Yoshiaki Hara, also a lead programmer who created a particular machine that can show the face of a person in ten years. Ayumi and Agasa take the first try. Agasa didn't change one bit, while Ayumi's photo looks beautiful. Genta and Mitsuhiko take the next seat as they turn into high-schoolers. Sonoko and Ran are next. Sonoko looks old, while Ran looks a bit like her mother Eri. Mitsuhiko and Ayumi look curious to Ran and Conan's reaction.
