The Alchemy Murder Case File 1 - S1-E6
Revealing mistake: When Kindaichi shifts the stage screen Miyuki is holding, her fingers are not gripping the sides in the new position. Unless she is keeping it up sticking the back of it to her palms like Spider-man, it is impossible. She does hold it normally in all the other shots. (00:01:55)
The Alchemy Murder Case File 2 - S1-E7
Revealing mistake: The director is drinking alone and freaks out about to go on a murderous rage. In the shot when she realises that her snacks have been tampered with and stands up, the bottle of "Yontory whisky" she is drinking from has a different texture from the rest of the scene. The snacks themselves also change position between shots. (00:17:00)
The Alchemy Murder Case File 3 - S1-E8
Revealing mistake: The setup of the story is the usual; characters forced to coop together at a secluded location, they can't contact the outside world and one of them is a killer. In this case, they are on an island and the only radio they had been on the boat that someone set on fire. However, when one of the suspects shows Kindaichi a photo from their smartphone, the screen shows that they have an active 3G connection. (00:08:00)
The Prison Prep School Murder Case File 1 - S1-E10
Revealing mistake: When Kindaichi and Miyuki speak with Kenmochi, inspector Adechi is lurking in the background reading what turns out to be a French newspaper. At the beginning you can see its "Le Shinbun" logo on both the front and back cover, but later in the scene it has just one cover and the back page is just normal text (incidentally, the filler text is garbage; the headline says "Je vais essayer de répondre l'incident" and even breaks the words incorrectly, but you have to freeze-frame to spot this last detail).
