Demon Hunter Organization

The Demon Hunter Organization (taima soshiki) is a important element of the Nasuverse within the stories of Tsukihime, Kara no Kyoukai, and Kagetsu Tohya. Though it is not often referred to directly it is related to many of the core characters of those stories. The Organization is made up of four families all of whom have a psychic ability (Thaumaturgy?).

The Families
Nanaya
 * Considered one of the most powerful families. Their psychic ability is a form of magan (Magical eye) that allows them to see people easier and see emotions(?). What makes them so powerful is their assassination skills which allow them incredible athletics and acrobatics (running/walking across walls like spider). Their skills and ability were transferred through bloodline, there Nanaya were incestuous to maintain the bloodline. Nanaya Kiri was the head of this family and also was one of the best assassins of the Organization. The family was slaughtered by Kishima Kouma who was ordered by Tohno Makihisa. One child survived the attack, Kiri's son, Nanaya Shiki who would later become known as Tohno Shiki.

Fujyou
 * The exact ability of this family is vague but as having a superior view of the world through blindness. The family seems to have collapsed though the exact cause is unknown. Known descendants of the family include: Fujyou Kirie who had the ability to project a ghost image of herself. Aswell as Hisui and Kohaku who had the synchronizer's ability to give life through fluid sharing (ie: intercourse).

Ryougi
 * The ability of this family is to create multiple personalities within themselves. The personalities are used to gain multiple skills (ie: one for acting normal and one for fighting). When a child is born they are given one name written two different ways in Kanji. This family is apparently still active but no longer fighting demons. The only known descendant of the family is Ryougi Shiki.

Asagami
 * The ability of this family is powerful telekinesis. This families main branch collapsed but one of the minor branches still exists (but is a business organization). The only known descendant of the family is Asagami Fujino. It is unknown if the family bears any relation to the Asagami Academy that Tohno Akiha attends.

The Purpose of the Organization
The main purpose of the organization is simple: destroy demons or demon hybrids that have thick demon blood. The Hunters of the Organization consider the demons a abnormality that must be corrected.
