The sixth Kara no Kyoukai movie is called “Oblivion Recorder”. Unlike the fifth movie, it only takes up an hour of airtime, and tells about another supernatural mystery case in which Shiki becomes involved. While it doesn’t match the standard that was set by the movies 3, 4 and 5, it nevertheless is a nice little movie.
In this movie, we learn that Mikiya has a younger sister. This movie shows her, as she tries to solve a murder mystery that took place in her school, helped by Shiki. The storyline this time is simple but effective, and there’s a nice layered mystery behind a seemingly straight-forward murder. The build-up is pretty well done, and overall this makes for an enjoyable movie.
Where this movie fails to live up to in comparison to its predecessors is that its scenario and execution lack polish. Mikiya’s sister turns out to be yet another girl with a brother complex. I dunno, I think that the creators tried to appeal to taboos, but that doesn’t really work when this trope is already used by tons of other anime. And overall, as much as I appreciate that we got to know more about Mikiya this way, as a main character for a KnK movie, she fails to stand out and is among the least interesting ones.
On top of that, the dialogue also feels rushed and uninspired for a movie. There are a number of conversations that clearly lack a bit of polish here and there, and there are quite a few plot-holes left open at the end of it, most of which I don’t think are going to be answered by the seventh movie. This movie simply doesn’t have the deep characters nor the addictive storytelling of the third, fourth and fifth movie.
What it does have, however, is the best CG during an action scene out of the six movies so far. Mikiya’s sister’s magic is very flashy and the creators make really good use of it during the action scenes. As a standalone movie Oblivion Recorder would have been fine, but the standards of the Kara no Kyoukai movies so far have become higher than average after all.
