Based on a novel by Nasu Kinoko, writer for TYPE-MOON. Kara no Kyoukai plays in a parallel universe to that of Tsukihime. Considered the precursor/inspiration for the story of Tsukihime.
Mikiya Kokuto finds himself intrigued by two things. The first is by Shiki Ryougi a beautiful, yet rather unsociable, girl and the other is the strange series of violent deaths that start occuring in his town. As he attempts to get closer to Shiki, he soon learns that the two are connected and that there are many supernatural forces at work which could very likely get him killed as well.
