Wind (episode)

is episode 55 of the Naruto: Shippūden anime.

Synopsis
Kakashi was released from the hospital and promptly began Naruto's training program. Naruto learned that he has wind-style chakra. Yamato helped by setting up the training field with his special technique. Naruto also learned that he can use his Multiple Shadow Clone Technique to speed up his training, since whatever the clones learn, the original user learns upon the clone's dispersal. Naruto and his mass of clones each took a leaf and attempted to slice it in half with wind chakra as the first step to creating his new technique.
