Blood Release: Forbidden Blood Gift

The second 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 user increases the potency of their own blood and them some portion of it is consumed by the recipient of the "gift." The amount that must be consumed varies, but is rarely enough to cause serious harm to the user.
 * Name: Forbidden Blood Gift (血遁・禁血恩賜 Chiton: Kinketsuonshi)
 * Type: S Rank, Supplementary, short (0-5m)
 * Users: Ketsueki Clan

The recipient of the jutsu, once completed, gains powerful Blood Release Kekkei Genkai of the Ketsueki Clan. This technique is what the Ketsueki family has used to hide their Kekkei Genkai, playing it off as a Hiden Jutsu. Anyone who is brought into the family is given the Blood Gift by the head of the family. Knowledge of this technique is restricted only to the head of the family and the eldest son (presently Hideyoshi and Mori Ketsueki).
