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.

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)

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)

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)

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)

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)

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)
