The Prison Prep School Murder Case File 1 - S1-E10
Continuity mistake: Once the Puppeteer disappears, you can't see Miyuki's glass and the box on the table any more either (but she has another table behind her when you see her hand in the foreground). (00:21:30)

Continuity mistake: After the Puppeteer's speech, the box emits sparks. Adechi shields his face with his sleeve fully in close-up, while in the wider angle he is mouth agape with the arm positioned at a lower angle. (00:20:50)

Continuity mistake: When Adechi sits down with the others, the handle of Kenmochi's cup of coffee faces Adechi in the first shot, Kenmochi in the next. (00:19:15)

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). (00:17:10)

Continuity mistake: When Kindaichi reveals that someone in the room probably is the responsible, Mizogishi asks in a shot from behind if anyone knows anything. In that shot, the two adjoined desks he was using become a single supersized table. (00:16:00)

Continuity mistake: When Mizogishi concludes his deduction, he puts the evidence bag down, and it is on the right desk, or on the left desk depending on the shot. (00:13:00)
The Prison Prep School Murder Case File 1 - S1-E10
Continuity mistake: During the interrogation scene there's a student with the same purple uniform Miyuki and Hitomi wear. She keeps switching sides, being next to the teachers or next to Hitomi, the latter being her wrong spot; the student next to Hitomi Kaidou is in other shots Yurika Enami, with her cream jacket. (00:09:00)

Continuity mistake: When detective Mizogishi begins his interrogation, the booklet inside the evidence bag is horizontal (longer side parallel to the longer side of the desk), then vertical (longer side perpendicular). (00:09:20)

Continuity mistake: Crazy-eyed Hitomi Kadou calls Kindaichi "dumb" out of the blue. Kindaichi is carrying his school bag over the right shoulder, but in the reaction shot his shoulder is clear. (00:06:05)

Character mistake: To show how hard the top students are working at the prep school, we see one of them writing; "I was at the course of a eight-week intensive." (00:04:50)

Continuity mistake: Kindaichi just discovered the murdered student. In the close-up of his hands clutching the crumpled paper, the spiked booklet and his closed fist are across two floor tiles. In the other shots, both were on the single last row of large tiles before the wall. (00:07:55)

Continuity mistake: The blonde student leads Miyuki inside the dilapidated school and says hi to the other student that is checking out a billboard. In the close-up you can see that she's standing on the left side of the billboard. In the wider angle she is standing on the right side. (00:05:35)

Continuity mistake: In the intro's last shot, the shadow on the puppet changes entirely from the rest of the scene. (00:00:40)
