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.

*Some context:* I have been seriously watching anime for over 4 years now, and I have never found the need to actually write a review. This would be my first one, so I hope you guys bare with it.

I'll explain my plight with a humorous short story - trust me, it's much more interesting that this anime:
In an art competition, an artist stands in front of his painting, and the judges walk up to him and ask him to explain the concept before opening and revealing the painting on canvas. The artist says that he has drawn the situation where: "Buddha lets fly a ...

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