"The Beginning of the Nightmare!!" (悪夢の始まり!!, Akumu no Hajimari!!) is chapter 317 of the original Naruto manga.
Deidara and his new partner, Tobi, confront the Three-Tails. Although it is his assignment, Tobi runs away in fright, forcing Deidara to intervene. In Konoha, Naruto makes steady progress with his Wind Release training. He nevertheless asks if there is someone else in Konoha who can use wind and could give him pointers. Kakashi directs him to Asuma. Asuma explains to one of Naruto's shadow clones that wind has great piercing potential. Naruto suggests that ordinary weapons would be better for such a purpose, so Asuma demonstrates how superior wind is to every other possible weapon. The clone disperses and passes what it has learned to the others. Meanwhile, word reaches Tsunade of Akatsuki's attack on the Fire Temple. She orders the Nijū Shōtai be gathered.
