劇場版「空の境界」第二章 殺人考察（前）

The story starts following an incident: a young girl jumps from the top of a building. The image provokes a certain dread, as the girl appears to have been a corpse even before she jumped. The case is dismissed, yet more and more of these suicides occur, and all from the same building. Thus began the rumour, that a ghost inhabited the rooftop of the building.

July 1998 - After a group of delinquents is found dead in their hangout place with all their limbs twisted and torn off, Aozaki Touko receives a request to find the murderer and asks Shiki for help. The main suspect is Asagami Fujino; a girl who was the boys' plaything until recently, who Shiki believes to be "one of her kind".

In February 1999, a string of murders has Shiki Ryougi and Mikiya Kokutou on edge. These crimes share a disturbing resemblance to a similar set of homicides from 1995, when Shiki and Mikiya first met, and awaken a dark, murderous desire that has laid dormant within Shiki's soul ever since then.

March 1999: Mikiya Kokutou meets Shiki Ryougi again at the same place where he met her for the first time four years ago...

Tomoe Enjou is attacked by bullies from his old school and saved by Shiki Ryougi. He asks her to hide him at her place and admits that he killed someone. Several days later, there are still no broadcasts about the murder as if it didn't happen... and when the victims are found, they're alive and unharmed.

One day, Koyomi Araragi encounters the horrifying vampire, Kiss-shot Acerola-orion Heart-under-blade A.K.A. the "King of Apparitions." He saves the fatally wounded Kiss-shot by offering his blood at the expense of his own life as a human. Now Koyomi has to face the vampire hunters to retrieve Kiss-shot’s limbs which were taken by these hunters...

June 1998: After spending two years in a coma caused by a traffic accident, Shiki Ryougi awakens with amnesia. She is visited by Touko Aozaki, a wizard and proprietor of a studio called Garan no Dou. Shiki has lost not only the memory of her accident, but also any real sense that she's even alive. Strangely, enigmatic beings begin to attack her...

Koyomi Araragi was turned into a vampire by the legendary vampire, Kiss-shot Acerola-orion Heart-under-blade, and he needs to revive the weakened vampire back to her complete form to return to being human again. The only way for Koyomi to achieve his goal is to fight the three vampire hunters – Dramaturgy, Episode and Guillotinecutter.
