"Coward…!!" (臆病者…!!, Okubyōmono…!!) is chapter 49 of the original Naruto manga.
Exam proctors find the dead bodies of three Kusagakure ninja. Anko recognises the work as that of Orochimaru and races into the Forest of Death to try and capture him. Meanwhile, Orochimaru, disguised as a Kusa ninja, recognises that Naruto is the jinchūriki of the Nine-Tailed Demon Fox. He seals off Naruto's access to the fox, takes his scroll, and throws him aside. Sakura catches him while Sasuke, inspired by Naruto's previous success, stages a counterattack. Using his Sharingan, Sasuke is able to defeat Orochimaru. As a reward for his skills, Orochimaru destroys their scroll and brands Sasuke with a cursed seal before leaving.
