The Prison Prep School Murder Case File 3 - S1-E12
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 2 - S1-E11
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: 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)
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.
The Prison Prep School Murder Case File 1 - S1-E10
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)
The Prison Prep School Murder Case File 1 - S1-E10
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)
The Prison Prep School Murder Case File 1 - S1-E10
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)
The Prison Prep School Murder Case File 1 - S1-E10
Continuity mistake: In the intro's last shot, the shadow on the puppet changes entirely from the rest of the scene. (00:00:40)
The Alchemy Murder Case File 4 - S1-E9
Plot hole: The ending is funny, but it does not make sense, since as it was mentioned in the first episode, there was literally 1 ton of metal to remove, and it was in the shape of a door. Not only it would have needed 32 trips (as the nerd girl says in the first episode) from the secluded house to a large boat they somehow needed to have standing by and was undetected when the island was searched earlier, but they also needed to dismantle the door, since that's what the gold was turned into.
The Alchemy Murder Case File 3 - S1-E8
Continuity mistake: When Kindaichi shatters the vase, its remnants and the flowers are positioned on a different spot of the floor between shots. (00:19:20)
The Alchemy Murder Case File 3 - S1-E8
Continuity mistake: When the producer is reading in bed the script for Gold Rush, he holds the book with 3 fingers touching the letters, which turn to 4 fingers in close-up. (00:09:35)
The Alchemy Murder Case File 3 - S1-E8
Continuity mistake: When the paper cup falls to the floor, it spills water between two floor tiles or just on one depending on the shot. (00:05:15)
The Alchemy Murder Case File 3 - S1-E8
Continuity mistake: Kindaichi and Miyuki visit the jittery former idol. She pours herself a drink of water from a bottle that changes shape between shots. (00:05:00)
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 Alchemy Murder Case File 2 - S1-E7
Continuity mistake: In the final murder of the episode, the smashed pieces of the vase change position on the floor between shots; easy to spot when you go by the floor tiles and the grid they form. (00:19:25)
The Alchemy Murder Case File 2 - S1-E7
Continuity mistake: When Miyuki wakes up from the drug effect, the bottle on the floor originated a puddle of water that changes between shots. (00:18:45)
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 2 - S1-E7
Continuity mistake: Miyuki and Reika are alone in the makeshift cell. When they sit on the bed after Kindaichi left them alone, the bottles on the table keep changing the direction they face between shots - just look at the "500 ml" notation, which faces the camera in 1 out of 3 bottles in the first two shots - which are taken at opposed angles - and then in all 3 bottles in close-up. (00:14:20)
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)
