The Prison Prep School Murder Case File 1 - S1-E10
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: 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)

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 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)

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: 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: In the opening shot of the 'briefing' about the camp's structure, Kendaichi's backpack is twice the size it turns out to be in the rest of the scene. (00:03:20)

Continuity mistake: When the teacher explains the timetable of the lessons, everyone has a booklet in front of them. Kindaichi despairs as the other people are walking away; his own booklet is missing now. (00:11:30)

Character mistake: When we first see Kindaich in English glass, the blackboard behind the masked teacher shows the word "grammar" misspelled into "grammer." (00:12:10)

Continuity mistake: At the beginning of the bamboo-cutter lesson, Kindaichi looks at the classroom door leaning against his right hand or not leaning at all depending on the shot. (00:21:05)
The Prison Prep School Murder Case File 2 - S1-E11
Continuity mistake: Miyuki's hairstyle is different in the first part of the episode (during the debriefing) and then gets back to what it was in the previous episode, with the two hair clips on the side instead of one at the back. On day 2, it switches again to one clip at the back.

Continuity mistake: Kujiragi grabs Kindaichi asking about his textbook; Kindaichi raises both hands almost putting them in the aggressor's face, but at the cut you get an unobstructed view of him; Kindaichi's arms are lowered. (00:05:00)

Other mistake: During the science lesson about DNA, the teacher shows the double helix structure. One wonders how could he draw it using 3 colors since he has just white chalk at his disposal. The figure disappears a moment later when he starts giving out the test papers. (00:06:30)
The Prison Prep School Murder Case File 3 - S1-E12
Continuity mistake: When Miyuki says that if they finish the test early, they will have a bit of time to relax, her pen is to the left of the paper. Close-up, and it's on the right side. (00:06:40)
The Prison Prep School Murder Case File 3 - S1-E12
Continuity mistake: The "Sunlight" group is being tested on Dostoevsky's "Demons." In the aerial opening shot of the test, Kindaichi is not holding any pen (it's on the desk), but in the next shot he does. (00:08:25)

Audio problem: Someone "accidentally" drops an eraser, drawing the teacher's attention. It's a soft pencil eraser with no additional parts, but it falls with a clicking noise as if it were made of hard plastic. (00:08:30)
The Prison Prep School Murder Case File 3 - S1-E12
Continuity mistake: When Kindaichi's classmate spots the corpse outside the window, he reacts putting a hand on his chest in the wide angles, on his mouth in the close-up. (00:14:15)
The Prison Prep School Murder Case File 3 - S1-E12
Continuity mistake: The burn marks on Adechi's tracksuit change throughout the episode. For instance, look at his left forearm; sometimes it has a dark spot, some other times it does not. (00:16:00 - 00:17:15)

Plot hole: Kujiragi's textbook is missing. It's a plot point and it's something the culprit did to plant an evidence using a page from it. However, when the case is solved, this point is glossed over; only a page from the book was needed, which the culprit could have ripped away at any moment without stealing the book, and more importantly, when Kindaichi finds the book, there was no window of opportunity for the killer to put it back; Kindaichi and Kujiragi were right there in the corridor the whole time. The live version adaptation fixes this hole because the character finds his book only the day after, in class.

Other mistake: Kindaichi puts on the table the map of the two buildings. The one to the right has a cutout part, but still shows as a full sheet. (00:19:00)
