Arc 4The Eastern Battlefield
Sōkyū Hatake fought Chiyo, helped expose Nara Rokuten as the mole, and outmaneuvered Sunagakure as Iwagakure’s movements threatened the village. The arc ended with Sōkyū learning from Ebizo that Ōnoki and Iwagakure’s missing forces might be heading for Sunagakure.
- Sōkyū Hatake killed the Elite Chunin captain and the remaining Chunin, then received Observation Haki and a new battlefield mission.
- After reports identified Sōkyū as the attacker behind Sunagakure’s western losses, he chose to deploy alone to the eastern battlefield, where his upgraded Observation Haki helped him detect threats.
- Sōkyū fought Chiyo with his lightning abilities and advanced Sage Mode until Tsunade intervened, forcing Chiyo to flee.
- Orochimaru and Sōkyū used a lie detector to expose Nara Rokuten as the mole, and Tsunade stopped him when he attacked Sōkyū.
- Sōkyū and Orochimaru spread news of Iwagakure’s missing forces to prompt Sunagakure to recall Rasa and Pakura, while Tsunade’s presence helped Konoha push back the offensive.
- Sōkyū fought Pakura, won their bet when she left to answer the battlefield signal, and brought her to Rasa, who agreed to a truce as Orochimaru negotiated compensation.
- Yamashiro Kōyō revealed that Nara Rokuten was a Root agent, but his Tongue Eradication Cursed Seal prevented him from explaining why he had leaked intelligence.
- Sōkyū questioned the imprisoned Ebizo, who feared that Ōnoki and Iwagakure’s missing forces were heading for Sunagakure.
