I feel like they could exist in the same universe, if magic is kept lowkey, but word of Gosho is apparently that the world in Magic Kaito and the one for Detective Conan are supposed to be parallel worlds, and that the Kid you see in DC technically isn’t the one from MK.

…Which I find most of what Gosho says during Q&As to be full of a ton of BS, so it’s still technically up for interpretation. He can’t actually keep his stories straight and I feel like he just makes things up when he needs a safe response. Kid is still clearly looking for something specific, and while it might not be an immortality granting stone, there’s… zero indication of what else it might be.

Magic in the DC universe would explain more than just the charms and premonitions, though. Haibara’s ‘BO sense’ is too convenient to brush off as normal, Conan has a similar ‘Kid sense’, and then there’s an apparent telepathic connection characters have that lets them know when something’s wrong with someone they care about. (See: Shinichi and Ran in general, Shinichi and Heiji like when Heiji was shoved off a ship into the ocean. It happens in canon, but the movies especially are bad about it.)

Not to mention that Gosho had a literal psychic tell Conan a big secret would be found out during the Holmes Freak murder case, and sure enough Heiji learned the truth.

Early DC did have a more fun, silly feel that a lot of older Gosho works had, even if it was in a more serious genre. A lot of the instances of things that can’t be explained have died down as the series goes on, which could be why there’s more of a push for a separation of magic from the logic. But people aren’t actually capable of separating the two in their mind, they just want to get rid of all the magic entirely, which is what annoys me. No hate on Magic Kaito for having magic. The MK fans don’t go hating on Detective Conan for not showing magic, they know Akako would probably break the DC world, so it’s just. Disheartening. When the opinion comes up that MK is at fault and ruining the DC experience because of the possibility of magic comes up.

Besides, the whole ‘took something that was supposed to be a poison but it changed me into a kid’ idea borders on the disbelieving side anyway, and yet it’s accepted without much fuss. Yes, it has some form of explanation later, but you had to have already invested time into accepting it without putting the series aside by the time you get that explanation. Magic shouldn’t be an experience killer compared to the very first time you read the series.
