Blood Release: Forbidden Blood Vampire

The first of the two Kinjutsu passed down through the generations within the Ketsueki Clan. Only those who have mastered Blood Manipulation can use such a potent jutsu. The target's blood is made more potent by the user and them some portion of it is consumed. The amount that must be consumed varies, but is rarely enough to cause serious harm to the target. When Mori used the technique to acquire the Sharingan from Itachi Uchiha, he only drank about a teaspoon of blood.
 * Name: Forbidden Blood Vampire (血遁・禁血吸血鬼, Chiton: Kinchikyūketsuki)
 * Type: S Rank, Supplementary, short (0-5m)
 * Users: Mori Ketsueki

The user of the jutsu, once completed, gains many of the jutsu and potentially Kekkei Genkai of the target. Due to the power and easily abused nature, the technique is strictly forbidden. There is only one copy of the scroll that contains the jutsu and, at the present, only Hideyoshi Ketsueki and Mori know of its location. Mori is the only person to actually be able to use it.
