|This is the article on the anime-only genjutsu used by Kosuke Maruboshi. For the taijutsu used by Kimimaro, head to Dance of the Willow.|
The user waves their sword back and forth, which when seen by the target locks them in a genjutsu which causes them to hallucinate multiple waving arms out to slash them. The movement resembles that of a willow tree blowing in the wind. With the enemy off guard, the user is free to cut them down.
