While there are hints and moments that suggest Conan *could* turn back into Jimmy at any time, the creators of Case Closed (or Detective Conan, as it's called in Japan) have made it clear that they don't plan to end the series anytime soon.
Here's why:
* Ongoing Mystery: The main storyline of Case Closed revolves around Conan's quest to find a cure for the poison that shrunk him and bring down the Black Organization. This overarching mystery keeps the series going, and the end of the series would likely mean the end of this mystery.
* Popularity: Case Closed is incredibly popular both in Japan and internationally. The manga has been running for decades, and the anime is still going strong. The creators are likely content to keep the series going as long as it remains popular.
* No Clear End: The creators have mentioned that they don't have a set ending in mind. This means they can continue to introduce new mysteries, characters, and twists without worrying about how it all ends.
So, will Conan ever turn back into Jimmy? It's possible! There have been several instances in the show where Conan's body starts to react to the antidote, hinting that he might be able to return to his original form. However, this is likely to happen when the time is right for the story, not necessarily at the end.
The mystery surrounding Conan's identity is a big part of the show's charm. It keeps viewers engaged and wondering what will happen next. It's highly likely that Case Closed will continue for many years to come, with Conan's transformation remaining a central element of the story.
