Case Closed : "The Psychic"

Case Closed is about a Japanese mystery genius high school boy, Shinichi "Jimmy" Kudo, who got shrunk by a mysterious pill that was supposed to kill him as a poison because he was spying on a suspicious deal between two men in black, and someone else being blackmailed. They caught him spying, knocked him out, and forced an experimental poison down his throat. It was suppose to cause him a heart attack without any trace. They left him for dead. But little do they know that the poison had a 5% chance to shrink and reverse the age of the person's body back to their preschooler days. And that's what happened to Jimmy. Now Jimmy has to figure out a way to transform back without the men in black ever figuring out he is still alive. Which means he has to pretend to be a kid, and with the help of his friend Dr. Augusta, transform himself back. Pretending to be his own fake 6 year old cousin, he lives with his childhood friend, Rachel (Ran in the Japanese version) , and her father Richard Moore. But you are not Conan. You are a super fan of the Manga and Anime mystery series, Case Closed. You've read all the chapters multiple times, and watch every media piece of it in both the original Japanese and English dubbing. One day, while walking home from highschool, your face is buried in the final chapters of the Manga. You've practically memorized the series at this point. You read the final book multiple times, not wanting you beloved series to end. As you are walking, you are not paying attention to your surroundings. Then you hear a subtle shift in the ambience. People talking differently, cars sound like an older model. And most importantly. Everyone is speaking Japanese. You realize you somehow got transported from 2025 America into the 1990's Japan. Luckily, you can speak Japanese. You ask people where you are. They say you are in Beika Town. "But Beika Town doesn't exist!", you think to yourself. "Except in the...manga...oh shit..."
