The Campground 'Bizarre' Case - S1-E17

Continuity mistake: When Kindaichi tries to escape and Miyuki stops him in his tracks exposing the reason why he's leaving, the cup in front of her is positioned with the handle facing right. When we see the cup again, it faces the opposite direction. (00:21:20)

Murder at 10,000 Meters File 2 - S1-E16

Continuity mistake: Throughout the episode, number and position of the airplane windows vary. You don't have to freeze-frame and count them; a cursory look at the door at the center of the plane is enough. The way the windows by it are grouped together changes in number and the door is sometimes at the end of the line, sometimes in the middle of it.

Other mistake: On the plane, Akechi is reading, according to the dialogue, an "English newspaper." The newspaper is called "Global Times", but it's not supposed to be the real life one, which is a Chinese newspaper (albeit with an english edition); the logo is different. However, for being a Western-style newspaper (which is what Kindaichi calls Akechi out for), its front page is positioned wrong, like a Japanese newspaper.

The Prison Prep School Murder Case File 5 - S1-E14

Stupidity: When the Puppeteer is shot, like any good villain he's actually wearing a bulletproof vest. However, a bulletproof vest is not a magical forcefield that neutralizes kinetic energy; this guy barely flinches when hit. Neither are flames; his fire trick raises a literal firewall, but firewalls are not literal walls, they do not stop bullets. The policemen could easily keep shooting through it (he throws a glove at Kindaichi through it), but they just do not, for no reason.

The Prison Prep School Murder Case File 3 - S1-E12

Stupidity: When Kirisawa's body is discovered, it means that he was completely overlooked during the headcount and at every point during the day. With students disappearing left and right, that's a pretty big oversight - that somehow the killer anticipated, because his body discovered last was crucial for the plan.

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 2 - S1-E11

Stupidity: The whole story of the 5 episode arc requires unhealthy amounts of suspension of disbelief; the killer directly challenged the police and announced where and when the murders will take place; at a 3 days prep school camp. Despite that, one of the teachers, a new one at the job even, is allowed to attend the camp wearing a ski mask, supposedly to hide hideous burns, and the police just lets him in without checking. And yes, he's the criminal, not even a red herring. By comparison, in the live version adaptation they check him, and he's wearing prosthetic scars.

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

Stupidity: Paragon of cleverness inspector Adechi somehow did not check for any trap in the mysterious box he received, and brought it to a crowded cafe just, so he could show it to the kids. For the explosive trick to work, the puppeteer needed also to know exactly where Kenmochi would be seated and which seats would later Kindaichi and Miyuki pick, since the box had to be at such an angle that the puppet would be propelled to the exact spot on the roof that acted as podium.
