Jujutsu (呪術, Viz: Curse Jutsu, Literally meaning: Curse Technique) are a type of techniques that harm the enemy by cursing them. They work similar to juinjutsu, however, the user doesn't have to apply a seal on the enemy to curse them.
The two named techniques of this type are Hidan's Curse Technique: Death Controlling Possessed Blood and Ryūki's Curse Technique: Body Controlling Manipulated Blood, where both requires the enemy's blood to curse the victim. In The Last: Naruto the Movie, an unnamed jujutsu was applied to the Tenseigan orb, making it impossible to be destroyed by anyone not part of Hamura Ōtsutsuki's lineage, instead draining them of their chakra. Mitsuki is noted to be skilled in jujutsu.
