The Beautiful Wild Beast…!! (美しき野獣…!!, Utsukushiki Yajū…!!) is chapter 51 of the original Naruto manga.
Sakura tends to the still unconscious Sasuke and Naruto. When she hears something approaching she turns around suspecting an enemy, but it is only a squirrel. She nevertheless makes it a point to scare the squirrel away, so that it can avoid the traps set for the enemy. Soon afterwards, Rock Lee finds the squirrel and save it from an explosive tag that has been applied to its back. At the same time, Sakura is confronted by three Sound ninja that express an interest in fighting Sasuke. Sakura asks why Orochimaru gave Sasuke a cursed seal, but they do not answer, in fact being surprised to learn of their master's earlier actions. They attack her, avoiding the traps that Sakura indirectly revealed by scaring away their squirrel-bomb, but she is saved by Lee.
