Chapter 32:

"A Tool Called Shinobi" – Gatô arrives with a small army of hired thugs, and the proceeds to kick Haku’s corpse in revenge for him guarding the recovering Zabuza. Naruto’s emotional outburst to protect those who love you inspires Zabuza, who borrows his kunai. Zabuza runs the gauntlet of thugs and slays Gato in front of them by clutching the kunai in his teeth and decapitating Gatô.

Chapter 33: "The Bridge of Heroes"

– Sasuke comes back from the brink of death, apparently “killed” in the same way Haku “killed” Zabuza. Sakura rejoices too soon as Gatô’s army closes in to finish their job, however, Inari and the rebels appear in far greater numbers. Naruto and Kakashi back them up with each performing Kage Bunshin. After the thugs flee, Zabuza and Haku are buried together as companions. Out of respect for Naruto’s deeds, Tazuna names the completed bridge after him. The team departs for Konoha, ending their adventure in the Wave Country.

Chapter 34: "Intruders!?"

– Introduces Moegi, Udon and the Konohamaru Corps. Being his usual perky self, Naruto runs around Konoha being loud and meets Konohamaru and his new play-gang. Sakura has a bad first impression of them which sends them fleeing, until Konohamaru literally bumps into an unknown pair of ninjas. The male one takes offence and grabs him violently. Then the Third Hokage announces to an assembled group of Jounins that soon, the Chuunin (mid-level ninja) Exam will begin.
