In a research facility hidden away on a remote island, genius programmer Shiki Magata has lived as a recluse for years. She rarely sees guests, but associate professor Souhei Saikawa and university student Moe Nishinosono still seek her out. However, their meeting is cut short when they are caught up in a locked-room murder mystery.

Everything is not as it seems, and many secrets are hidden. Within an isolated facility, a seemingly impossible and gruesome crime takes place, and Saikawa and Moe must unravel the truth behind the murder and Magata's shrouded past.

The Perfect Insider is what I would like to call the first 'proper' mystery anime I've seen in quite some time. By 'proper' I don't mean to say that it's amazing per se, but that it actually follows the best story design for the genre. That is to say, it takes its time to give the viewers all the details you could ever ask for as well as plenty of red herrings, it doesn't blatantly break the rules of detective fiction like certain other recent works, and it is also not episodic in any way.

But hey, regardless of quality, I think most of us can agree it’s still worth talking about. Not to mention, I get to ...
