Rock Lee vs. Neji Hyuga (ロックリー対ガイ班はネジ日向 Rokku Rī tsui Neji Hyūga) is Chapter 3 of the manga.
Several shinobi from Kusagakure appear in Konohagakure. When Rock Lee comes with the intention to stop them, they claim that ninjutsu will not effect them. Notwithstanding, Lee knocks out the three ninja with taijutsu. While defeated, they question why he had not used ninjutsu, and Lee simply replies that he cannot, thus he works hard to improve his taijutsu.
Tenten and Might Guy arrive, with the latter dressed in a ridiculous outfit that consists of a tutu. Lee is shown dressed in the same attire, and he and Guy resume their training, much to Tenten's disbelief. Lee muses to himself that he has completed the mission better than his rival, Neji Hyuga, based on the number of ninja he has defeated. However, Lee then realizes that Neji has defeated the Kusa-nin's leader, hence beating Lee's "quantity with quality".
Later, Tenten is searching for her valuable photo that she has lost, and claims that she wished Neji was there, due to the fact that his Byakugan allows him to search the area thoroughly and efficiently. Lee attempts to perform Byakugan by straining his eyes back, and Naruto Uzumaki mistakes him for a suspicious person. Frustrated that he cannot find Tenten's photo, Lee shouts that he wants to prove that genius is something that can be overcome by hard work. Subsequently, Neji arrives, having retrieved Tenten's photo in the matter of seconds, and Lee swears to never to lose to Neji again.
Guy recalls the time when the team first collaborated and that Neji was really arrogant at the time, claiming that Lee can never become a ninja without ninjutsu. Tenten dotes on Neji about his high capacity, and Lee challenges Neji to a fight.
After a week of training, Lee comes back, looking considerably muscular. Guy is so as well, however only his right arm is preeminent. The battle begins between Lee and Neji. Lee picks him up by the head with ease, but Neji evades it with Substitution Jutsu. Neji then uses his Eight Trigrams Sixty Four Palms Jutsu, and air seems to leak out of Lee, resulting to him returning to his original form. Guy explains that it is chakra that is leaking out, due to Neji's jutsu, which is able to manipulate the target's jutsu.
Lee uses his form of Byakugan, which catches Neji off guard. Quickly after seeing an opening, Lee charges at Neji with Six Trigrams Sixty Four Headbutts. In the end, they both are damaged, and the match ends as a draw. Neji then tells Lee that he has become an amazing ninja. Guy prompts that he, Lee and Neji undergo extreme training, and the next day they all appear excessively muscular.
