How old is Ai Haibara? Does she have the same years old with Shinichi and Ran?
Good question, but no concrete answer. There was once a big discussion in the FORUM about Ai’s real age. Some people believe Ai is as old as Shinichi or slightly older (2-3 years older). If so, Ai must be very talented because she’s able to create the shrinking drug at this young age. However, some people believe Ai is much older than Shinichi, but still less than 30. As far as I remember, Gosho never really said about Ai’s age. There was once an episode that Conan asked Ai about her age. She said that she was the same as Shinichi, but she said that she was kidding. It could be a joke or it’s real.
