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)

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)
