Academy's Seven Mysteries Murder Case: File 1 - S1-E1
Other mistake: Miyuki dirties her hand with ketchup leaning against a wall; however, the white wall has no red markings. (00:04:00)
Academy's Seven Mysteries Murder Case: File 1 - S1-E1
Continuity mistake: Miyuki and the other girls happen by several bloodstains which turn out to be a result of Kindaichi's messy eating habits. When Ruiko Sakuragi makes her appearance, the gory ketchup mess in the corner is gone. (00:05:15)
Academy's Seven Mysteries Murder Case: File 1 - S1-E1
Continuity mistake: During the introduction of Sakuragi's card puzzle, the cards change position between shots; for instance the two of spades in close-up bridges across two adjoined desks, while it's in a completely different spot in other shots. (00:07:40)
Academy's Seven Mysteries Murder Case: File 1 - S1-E1
Continuity mistake: When Sakuragi hands Kindaichi the meeting minutes from 1987, the floppy disk is in a different position in the wider angle, and the book itself is headlined by two kanjis written vertically, instead of horizontally like in close-up. (00:10:35)
Academy's Seven Mysteries Murder Case: File 1 - S1-E1
Continuity mistake: Sakuragi hints that she knows Makabe's secret, and snubs him completely. He storms out and stumbles upon his ghost writer Tomoyo Takajima. She is wearing just a right glove, but when he backhands her, she is wearing gloves on both hands. (00:12:25)
Academy's Seven Mysteries Murder Case: File 2 - S1-E2
Continuity mistake: Kenmochi puts his hand on Kindaichi's shoulder, open palm and full grip. A split-second later he's waving at him the police badge with the same hand. (00:02:00)
Academy's Seven Mysteries Murder Case: File 2 - S1-E2
Continuity mistake: One of the reporter's that act as audience and supporters for Makoto is quite recognizable because he's in the front line and wearing glasses. His jacket is reddish/maroon at first, but in the rest of the scene becomes purple/blue. It's not a matter of lighting or lack of detail when he is in the background/shadows, just compare it to the guy next to him wearing green to see it's a proper coloring mistake. (00:06:20)
Academy's Seven Mysteries Murder Case: File 2 - S1-E2
Other mistake: Kindaichi is afraid something might have happened to Miyuki. Finding blood, he has a flashback with several images about her. The final one though, the one with her sticking her tongue out and making a funny face, is something he can't reminisce about, since he wasn't there at the time. (00:18:40 - 00:21:00)
Academy's Seven Mysteries Murder Case: File 2 - S1-E2
Continuity mistake: When Makabe puts Miyuki against the wall, the shadows on the wall and the position of her hair in front of the shoulders are inconsistent between shots. (00:18:50)
Academy's Seven Mysteries Murder Case: File 3 - S1-E3
Other mistake: The beginning of this episode does not match the previous one; Saki at the climax of the previous episode asked "Is that blood?" filming the scene, standing behind Hajime. In this episode he asks that when Kindaichi already turned around and grabbed him by the neck. (00:01:50 - 00:21:10)
Academy's Seven Mysteries Murder Case: File 3 - S1-E3
Plot hole: A corpse has been buried inside the walls of the building for 10 years. It's covered by just a poster, and a poster from a current high schooler. If we assume the first victim was the one who put the poster there, then it means that it was just randomly uncovered by the earthquake from episode 1, which would make the chain of coincidences nothing short than miraculous. She basically one day said "I heard there was a murder here where we all hang out all the time" and the ground by its own accord opened to reveal a skeleton without her doing anything.
Hiren Lake Legend Murder Case: File 1 - S1-E4
Continuity mistake: When Kindaichi falls through the bridge, he's carrying the bag on the left shoulder first, the right shoulder then. (00:06:15)
Hiren Lake Legend Murder Case: File 1 - S1-E4
Continuity mistake: When Kindaichi and the others talk with the mature couple, the president is wearing a purple-ish jacket and a red shirt. At dinner, they make a comment about Miyuki and Eiji Touno being a couple. From behind, the president is wearing his jacket, but from the front he's just wearing the red shirt. (00:09:40)
Hiren Lake Legend Murder Case: File 1 - S1-E4
Continuity mistake: During dinner, the writer (Itsuki) approaches the artist (Kobayashi). The food in front of Kobayashi changes between shots; in the overhead shot of the table you could see just a small plate with two chopsticks, which change position in a later shot, with a beer glass added too. (00:10:00)
Hiren Lake Legend Murder Case: File 1 - S1-E4
Continuity mistake: After they find out that the bridge has been destroyed, the survivors debate what to do. One of them mentions that it's suicide to go in the woods without a map. He does so getting in front of Kindaichi in the aerial shot, but he's behind him in the next shot. (00:14:50)
Hiren Lake Legend Murder Case: File 2 - S1-E5
Continuity mistake: Hajime grabs Eiji by the collar of the shirt using his right hand, which ends up being his left hand when Miyuki wakes up. (00:02:40)
Hiren Lake Legend Murder Case: File 2 - S1-E5
Continuity mistake: Eiji just left to get help through the lake. When Miyuki says "Not really" on the topic of jealousy, the sheets are pulled all the way up to her chin, but they are lower in the following shot. (00:06:45)
Hiren Lake Legend Murder Case: File 3 - S1-E6
Plot hole: As it often happens in this sort of murder mystery, there's a switching act at one point, and one of the 'disfigured bodies' is not who it is presumed to be. Good, but the problem is that the presumed victim and the person who really died have radically different skin tones, and it'd be practically impossible for anyone who knows them to mix them up - even moreso for the genius detective Hajime Kindaichi.
Hiren Lake Legend Murder Case: File 3 - S1-E6
Plot hole: Kindaichi's denouement can happen only because the killer misses half a dozen people leaving the cottage covertly; Kindaichi does not have a clue of the killer's observation point, and despite what the detective says, the killer was not just listening, but watching them too with binoculars. Moreover, moving a microphone sensitive enough to capture the sounds of the whole room would produce noises which would have alerted the killer that they were tampering with it.
