The Akatsuki Suppression Mission (“暁”討伐任務, "Akatsuki" Tōbatsu Ninmu), known as the Immortal Devastators — Hidan and Kakuzu (不死の破壊者、飛段・角都, Fushi no Hakaisha Hidan Kakuzu) in the anime, is an arc from Part II of the series. This arc sees Konoha's fight against Hidan and Kakuzu of Akatsuki. It spans through volumes 35 to 38, or more specifically, covers chapters 311 to 342 of the manga and episodes 72 to 88 of the Naruto: Shippūden anime. Kakashi explained that there were five basic types of elemental chakra: fire, wind, water, lightning and earth. He pulled out special cards which reacted differently to each person's chakra: it would burn for fire, split for wind, crumple for lightning, turn to dust for earth, and turn wet for water. Naruto flowed his chakra into the card and it split, indicating he had an affinity to wind, a type that is very well-suited for combat because of its ability to "blow past anything and slice things to bits". Meanwhile, Asuma and Shikamaru were playing shōgi. Shikamaru noticed that Asuma was playing differently from normal, and asked if something was wrong. In describing things, Asuma described Shikamaru in terms of shōgi as a Knight, being weak in terms of power but having a unique style of movement which resembled Shikamaru and his flexibility in his thinking. Shikamaru then asked what piece Asuma resembled. Asuma then answered that he was just a pawn. Shikamaru guessed that the Hokage was the king, but Asuma told him that it wasn't, and that someday Shikamaru would understand. The first phase in the training was for Naruto and his clones to cut a leaf with his chakra. Naruto asked if there was anyone in Konoha that could give him advice, and Kakashi told him to find Asuma. Asuma gave Naruto a few pointers, using his trench knives as an example. They were made of a metal that absorbs chakra, the effect of which is determined by the user's chakra nature. Asuma explained that wind chakra must be sharpened like a blade by splitting the chakra in two and bringing the parts together to form a tight edge. He demonstrated this by having Naruto toss a knife at a tree with him: Naruto's stuck in the tree while Asuma's went straight through it and pierced a rock. If he had used his full chakra, the knife would have also gone through the rock. Using this advice, Naruto was able to completely split a leaf, but passed out after dispersing his clones. Kakashi warned him that this training was going to wear him down quickly, and that he needed to rest for the next phase of his training: slicing a waterfall in half. The next step of Naruto's training progressed slowly. When Naruto complained, Kakashi noted that even Sasuke had taken several days to learn to manipulate an element, while Naruto had done it in a few hours. By nightfall, Naruto still hadn't managed to cut the waterfall. Naruto reflected on his fonder memories of Sasuke, and decided to train through the rest of the night. By the next day, he and all his clones were able to cut the waterfall. Yamato was surprised by Naruto's progress, but Kakashi wasn't, since he understood how Naruto felt about Sasuke. Kakashi declared that they could finally move into the final stage of Naruto's unique technique creation. However, the constant training had exhausted Naruto once more. Kakashi immediately rushed to his side, concerned that he might have pushed Naruto too far this time. However, when Naruto moaned that he was hungry, Kakashi relaxed.
