the keepers of an ancient secret jutsu, the kura clan is extremely secluded. They live in the forests in between konohakagure and sunakagure, but no one knows exactly where. Not much is known about the clan, except that whenever a member is seen in town, a death soon follows.......
Bloodline: chirouki summon
The members of the kura clan have an extremely rare ability. When a member of this clan kills there first person, the chirouki that lies within them comes out onto their skin. The chirouki is like a leech, that feeds off death. The more people a person that has the chirouki kills, the stonger the chirouki gets. The chirouki is like a factory, and it produces chakra for its host to use. The stronger the chirouki gets, the more chakra it makes for the user.
