Reincarnation Ninjutsu

are techniques that require or accomplish the transfer of life force between people. Under normal circumstances, due to the death of the user being involved, such techniques are generally classified as kinjutsu. The restoration of one life usually requires the sacrifice of another. However, though considered a kinjutsu, Impure World Reincarnation is an exception among Reincarnation Ninjutsu as the user's life is not at any risk.
