Slip at Sea

Under the sea 

Darling it's better

Down where it's wetter 

Take it from me

"The Little Mermaid"

The last year or so, I've been trying out the anime original episodes of Detective Conan, so the episodes that were not based on the original comic, but written especially for the animated series. There have been some fine gems there, but a lot of them are pretty forgettable. But when I was writing my review of the PlayStation 2 game of Tantei Gakuen Q, I recalled the animated adaptation of the adventures of Q Class of the prestigious Dan Detective School also featured a couple of anime original episodes. I couldn't recall what those episodes were about though, and as there were only a few of them, I decided to skim through them again.

Most of them turned out to be very forgettable, of course. I had completely forgotten that the animated series had a whole series of four anime original episodes at the very start of the series, but they are all very simple (revolving around one single trick) and these episodes mostly serve as character-focused introductions for the various members of the main cast, giving the viewer an early glance at what makes them tick and how the members of Q Class learn to work together. The animated series only adapts the first half of the manga, so it features an original two-parter ending to end the story, but that story is nothing special either. Strangely enough though, no less than two anime original episodes were about a bomb terrorist.

In the end, I think that only one anime original episode left an impression on me. Suishin 30m - Kaitei Misshitsu Satsujin Jiken ("Depth: 30m - The Case Of The Locked Room Murder At The Bottom of the Sea") was originally broadcast on July 22, 2003 and features a surprisingly densily plotted mystery considering the relatively short runtime of one single episode  about twenty minutes). During the summer holiday, the five members of Q Class decide to go scuba diving together. When Kyuu, Ryuu, Megu, Kinta and Kazuma arrive at the shop however, they find a group of distressed doctors and nurses who are on holiday together. One of the members of the group, Doctor Ikezoe, had a bit too much to drink last night, and he hasn't been seen since. Ikezoe had been talking about wanting to take a night dive, and when the people from the shop notice one set of scuba gear is missing, they fear Ikezoe may have gone out diving in the middle of the night on his own, and gotten in some trouble. They suspect Ikezoe went diving near a sunken shipwreck resting on the sea bed (a popular diving spot), so they decide to go diving near the ship to see if they can find him. Kinta reveals that they are students of Dan Detective School and are taken along too.

The divers of the search party scatter around beneath the sea surface and eventually locate a deceased Ikezoe behind the locked door of one of the cabins of the sunken ship. They force the door open, and bring his body back up. The doctors determine that Ikezoe died of a head fracture and that he had alcohol in his blood, so it's assumed that he must've been diving while drunk last night, locked himself up by accident in the cabin and then hit his head against one of the walls. An attack on Megu while under water and more curious facts however suggest to Q Class that this was no accident, but foul play and they quickly determine how the murderer managed to create a locked room inside a sunken wreck.

Whereas the other anime original episodes revolved around one single idea (like one dying message), this episode is a lot trickier, with far more elements to consider. There are clues why it wasn't a murder, clues that point to how it was done, clues that point to the identity of the murderer and taken together, the plot of this episode is really quite decent. While the murderer makes one really lame mistake (the clue that allows you to identify that character postively as the culprit), the other elements are far more promising. The actual explanation behind how the room was locked from the inside isn't that original, but it makes really good use of the setting of this episode and the highlight of the episode is of course the whole matter of how the murderer managed to kill Ikezoe and leave his body safely inside a locked cabin while they were under water. The trick used here is really good, because it is so much more convincing in the visual format compared to if you had been reading about this in a novel, and the trick also works because actually solving the trick also requires the special abilities of one of the main characters. Tantei Gakuen Q is at its best when it provides a story where the individual skills of the various members of Q Class are integrated naturally into the mystery plot (for example when the plot relies on Megu's photographic memory, while the reader can simply turn back a few pages). Count in the fact the story does a great job at setting thist last part up in a convincing manner, and you've got the best anime original episode of this series.

And as a side-note: it had been a while since I last saw the anime, but it's such a shame this series never got a soundtrack release! There are some really great BGM tracks, like the fantastic main theme. The live-action drama had a soundtrack release, so why didn't this one get a release?!

In general, I did enjoy the anime adaptation of Tantei Gakuen Q, but as for the anime original content, I think Suishin 30m - Kaitei Misshitsu Satsujin Jiken is the only episode really worth mentioning. While not a classic like Conan's Noroi no Kamen wa Tsumetaku Warau, this episode's a surprisingly well-plotted story considering its limited runtime and worth the twenty minutes investment, also if you have already read the manga of Tantei Gakuen Q, but haven't seen the animated series.
