Kara no Kyoukai was originally an online released dojin written by Kinoko Nasu and illustrated by Takashi Takeuchi. The five chapter series was well received and brought Nasu and Takeuchi to form what we know as the present Type-Moon.
Kara no Kyoukai can be said to be the prototype of Tsukihime not just because of the timeline but because of the setting and characters. Similar to Tsukihime, Kara no Kyoukai takes place in a world where dead apostles, vampires, magicians, and other fantastical existences reside.
Furthermore, the main character is named Shiki, wields a knife, and has Mystic Eyes of Death Perception. The eyes are a token concept of Type-Moon. Whoever has these eyes can see the death lines of any object or person as well as the origin.
If they cut along the lines, they will slice through the target as easily as butter making damaging them very easy. If the pierce the target’s origin points, they will destroy the existence of the target not only effectively killing them but completely destroying any reincarnation resulting in its absolute destruction.
Shiki in the universe of Kara no Kyoukai is portrayed as a unsociable girl who denies any human contact. On the flip side she is related to a slew of mysterious deaths that have occurred around the town.
It has been said that the male protagonist, Kokutou Mikiya of Kara no Kyoukai is the prototype for the male protagonist of Tsukihime, Shiki Tohno. Also, as the “origin” story for Nasu’s works, Kara no Kyoukai introduces many themes and terms that are frequently used in later works such as Tsukihime, Mahoutsukai no Yoru, and Fate/Stay Night.
Fans of the movie series have been anticipating an actual date since the second PV revealed a Fall 2013 release. Mirai Fukuin will focus heavily on Mana Ryogi, daughter of the two main leads Shiki and Kokutou.
Up until now there have been seven movie adaptations of Kara no Kyoukai. The upcoming film, Kara no Kyoukai: Mirai Fukuin, will be the eighth one in the series. In just a short three months, the film will be hitting the big screen in Japan so be excited!
