Poison Moth Genjutsu

Fuen first uses poison that is thin and tiny enough to be taken in the air. Her target will inhale the poison and start to see the things that Fuen chooses, like caves, moths, or allies of the target trying to kill the target. When her target is imprisoned in her genjutsu, Fuen charges and kills her target. Sakura Haruno was able to create an antidote for the technique, allowing her to defeat Fuen.
