Small history:
This clan was made before 1000 years. Each 8 years there is a war named "The Holly grail war" in which 7 warriors would participate. Each warrior had a summoning that could be summoned only once from the same person. They called them servants. But to win the war the warrior had to kill all the warriors or their servants. If the servants would get killed they would get back to their previous status and wait for another 8 years to be summoned from another warrior. For the winner of the war the Holly grail will revile himself and granting any wish they want. But the results of the war would be catastrophic. A lot of innocent people would die and the warrior that has won the war has never been seen again. When Kaemon participated in the war and won he saw that the Holly grail was responsible for the destruction and than he destroyed it and finishing the war forever. Than he was proclaimed as the leader of the clan.
Now the clan lives peacefully without worrying for the war. The clan is settled few kilometers from Konoha. Not all members of the clan have this bloodline. Only 20% of the clan got the bloodline.
