Junketsu Clan

The Junketsu Clan is a nomadic ninja clan that never joined any of the ninja villages. The reason they did not assimilate into any of the ninja villages was not due to unwillingness on their part. Rather it was villages themselves that rejected the clan. This was because the Junketus had earned an extremely infamous reputation on account of their Kekkei Genkai, which allowed them to drain the blood from others and store it in their own bodies, a necessity for the clans special physical enhancement jutsu. This lead many to believe that the Junketsu were not actually human, and thus were literally monsters. This misunderstanding persisted until the Junketsu had to go into hiding, and became the stuff of legend. The Junketsu remain in hiding, but hope for the chance to regain their lost glory.
