Jujei (Earth-2356)

Jujei are a type of Force techniques that harm the enemy by cursing them. They work similar to juinjei, however, the user doesn't have to apply a seal on the enemy to curse them.

The two known techniques of this type were Hidan's Curse Technique: Death Controlling Possessed Blood and Komari Vosa's Curse Technique: Body Controlling Manipulated Blood, where both required the enemy's blood to curse the victim.
