A girl named Ryoko Akagi came to the Mouri Detective Agency asking for help to find her boyfriend who suddenly disappeared. The alleged 'boyfriend' in the photo was Shinichi Kudo!
Meanwhile, in the Sunday Cup Finals, Tokyo Spirits' star soccer player Hideo Akagi was missing easy shots seemingly on purpose.
- Evidence
- There were marks on the front door lock of the Akagis' house indicating a forced entry.
- The shoe rack contained men's and children's shoes only.
- The way Ryoko rummaged through the cupboards, it was as if she didn't know where the utensils were.
- One of the rooms was trashed. A picture of a man and a boy confirmed that its occupant was a child named Mamoru Akagi.
- The man who was with Mamoru in the picture was Hideo Akagi, the professional soccer player whom Ryoko was watching on TV.
Conan knew that something was up for he didn't really know Ryoko. With the clues at hand, Conan pieced things together.
He immediately called Ryoko as Shinichi using the Voice-Changing Bowtie and the Portable Bentou Box Fax. He confirmed that Mamoru was indeed kidnapped. Mamoru was Hideo's older brother whom Hideo has been taking care of since their parents died two years ago. Hideo was ordered by the kidnapper to throw the game. Threatened that Mamoru would be hurt if the police was involved, Ryoko decided to pose as Shinichi's girlfriend.
When Ryoko came over to make breakfast, she found a letter left by the kidnapper and another which the kidnapper apparently made Mamoru wrote. Ryoko faxed Conan a ripped letter with the words: "Brother, resurrect me."
While trying to find more clues in Mamoru's room, Conan thought that it was just too messed up even if the child retaliated. And with further investigation, Conan found an empty game box called Onimaru Quest - a game where the hero has to be 'resurrected'. The main character in that game was named Mamoru. Another character in the game was named Naoki. Uemura Naoki was a soccer player who joined the Tokyo Spirits a year ago. He was also Hideo's good friend who lives nearby.
Conan deduced that Mamoru was with Naoki and that it was just made to look like it was a case of kidnapping. The note that Mamoru left must have been a part of the whole saying that he was going to Naoki's to have his character revived.
The group rushed to Naoki's place and sure enough, they found Mamoru there unharmed.
Naoki envied Hideo because even though their skills were pretty much the same, Hideo was still more popular than he was. He came close to surpassing Hideo but during one of their practices, Hideo accidentally injured his leg. Naoki thought that it was done on purpose so he wouldn't be able to play.
Naoki didn't plan to hurt Mamoru. He would send Mamoru home after the soccer finals and Naoki would disappear after getting back at Hideo.
