Genjutsu: Ketsuryūgan

By establishing direct skin or eye contact with a target, the user can lock them within a genjutsu for one of various purposes. They can brainwash them into mindless drones with a set order to follow, or trap them into a dream-like state. For more defensive means, this technique can create a powerful barrier against mind reading, protecting information from being acquired. In the novel, it also allows the user to see through the target's memories.
