Moe Nishinosono is infactuated with her professor Sohei Saikawa. One day she goes visit Shiki Mugata, a prodigy who gained her doctorate at the age of 11 but found to be guilty of murdering her parents one day. Yet, Mugata claims she didn't. She also happens to be held in high regard by the professor because of her high intelligence. Just to tease her professor further, Moe decides to make the annual camping trip to visit the remote island Mugata was being isolated at again. However, when they go to meet Mugata they discover her murdered, left with a severed body and in a wedding dress. Bothered about the odd questions she was asked during their meeting, Moe decides to take on the investigation herself together with her professor, Sohei.

So this is an Anime based on a mystery novel by Hiroshi Mori. Art style is clean and has a calm atmosphere to it most of the time. Everyone mostly goes about as if nothing happened but, it can also get really creepy when the mystery picks up again thanks to its good use of sound. Thankfully there's a bit of romance between teacher and student (!) who both kind of lighten up the show a bit. If you're a programmer, you might find the show interesting too because it's quite technical.

One thing for sure is, you won't want to watch this if you're after a nice bed time story.
