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)
The Prison Prep School Murder Case File 3 - S1-E12
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.
The Prison Prep School Murder Case File 3 - S1-E12
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)
The Prison Prep School Murder Case File 2 - S1-E11
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)
The Prison Prep School Murder Case File 2 - S1-E11
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)
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)
The Prison Prep School Murder Case File 1 - S1-E10
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)
The Prison Prep School Murder Case File 1 - S1-E10
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)
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). (00:17:10)
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)
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: 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)
The Prison Prep School Murder Case File 1 - S1-E10
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)
The Prison Prep School Murder Case File 1 - S1-E10
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)
The Alchemy Murder Case File 4 - S1-E9
Continuity mistake: In the flashback when we see the culprit holding the newspaper with the news about the suicide, their thumb is on the blue box, which is at the edge of the page. Then they fall on their knees crying, and there's suddenly an extra bit of newspaper to the right of the box and their hand is on that. (00:15:15)
The Alchemy Murder Case File 3 - S1-E8
Plot hole: The locked room mystery is original, but besides the fact that it requires melting part of a door on the spot and being able to repair it absolutely flawlessly so that nobody would notice any bump and discolouring and irregularity when they check the lock later investigating the murder, it also requires them to do it in total silence so the other guests don't notice, and part of the process shown involved cutting through it with a screwdriver and bashing it with a hammer - they show that and there's even a loud sound effect for it. (00:18:00)
The Alchemy Murder Case File 3 - S1-E8
Factual error: The Latin text on the supposedly old tome (which is written with a modern font) displays an alchemist diagram. It is a reproduction of a famous drawing meant to portray the Philosopher Stone in the Sylva Philosophorum, but whoever copied it does not know Latin, because certain words are misspelled ("Merceralia" instead of "Mercurialia", "Humides" instead of "Humidus"). (00:10:10)
The Alchemy Murder Case File 3 - S1-E8
Continuity mistake: Mikage is startled by someone knocking at the door. She then puts the knife back on the desk when she realises who is it. The knife and the towel she partially hides it in are in the middle of the desk, but when they tell her that she is a likely target, the items are on the edge of the table. (00:05:10)
Reika Hayami and the Uninvited Guest - S1-E5
Continuity mistake: In the hall where Reika holds the quiz, the participants keep changing clothes throughout the scene depending on the camera angles.
The Hong Kong Kowloon Treasure Murder Case File 4 - S1-E4
Plot hole: Miyuki has been peacefully waiting for over a day at a stranger's house because she was told that the whole Hong Kong was under lockdown and her friends were in another location. That cover story (which would have been exposed if only she looked out of the window, people were NOT in lockdown) does not explain at all the kidnapping in the clothing stall or why she didn't have her phone or talk to Hajime at any point. She'd have to be braindead not to question even slightly what was happening.
