The Hong Kong Kowloon Treasure Murder Case File 2 - S1-E2
Plot hole: An essential part of the plot relies on the fact that thanks to Saki's handheld camera, Kindaichi can examine Ran's arse dragon and therefore investigate even in her absence. But what set the plot in motion was the fact that Ran appeared in a professional modelling photoshoot displaying it. Stupidity of the girl aside, that means that the culprit never needed the girl, having HQ shots of the tattoo at their disposal. They even work for the company.

Other mistake: When Saki shows the picture of Ran's butt, the photo is taken from the right of the girl. In the scene during the previous episode, Saki was standing on Hajime's left, and he could never take that shot from that angle.

Other mistake: Miyuki calls Kindaichi at 9:48 AM. Hearing the pink dolphin hint, they run to the Kowloon Palace statue. When at that location Saki shows him the picture, the cell phone says it's 15:24. Too much time elapsed between the two moments. (00:17:00)

Continuity mistake: Hen Ivy calls the actual Ran in disguise "Ran-san", Saki is pointing the camera at her in one shot, and his arm is all the way down his side in the next. (00:09:25)
