Chapter Summary: Susanoo: Third Form

Key Plot Points and Events

• In a tavern on Tanzaku Street, Jiraiya tries to persuade Tsunade to return to Konoha and become the Fifth Hokage following Hiruzen Sarutobi’s death.
• Tsunade rejects the position, claiming she has long abandoned both Konoha and the idea of becoming Hokage. Jiraiya then reveals that an individual in Konoha has awakened Wood Release.
• The revelation immediately captures Tsunade’s attention because Wood Release was the signature power of her grandfather, Hashirama Senju, the First Hokage.
• Naruto enthusiastically identifies the user as Uchiha Yao, describing how Yao defeated Gaara’s transformed Shukaku during the Chūnin Exams with a massive Wood Release construct and overwhelmed its Tailed Beast Bomb.
• Jiraiya confirms that Yao is a twelve-year-old Uchiha orphan, Kakashi’s student, and the older brother of Sasuke. Reports from Kakashi and the Anbu suggest that Yao’s Wood Release is extraordinarily powerful, potentially resembling Hashirama’s abilities.
• Tsunade is deeply unsettled by the fact that an Uchiha can wield Wood Release, since the Uchiha’s Yin-based Sharingan and the Senju’s Yang-based Wood Release are fundamentally different. She suspects that forbidden experimentation may be involved, but the mystery also strengthens her desire to return to Konoha.
• Meanwhile, Yao teleports via the Flying Thunder God Technique to a secluded mountain valley to train away from Konoha.
• His main focus is improving his newly mastered Susanoo and refining his Mangekyō Sharingan.
• Because Yao possesses the Sage Body, his exceptional vitality and regenerative abilities largely counteract the physical damage and risk of blindness normally caused by Mangekyō use.
• Through repeated practice, Yao rapidly improves his control. His Susanoo now forms smoothly and can maintain its third form for several minutes, with increasingly powerful armor, chakra density, and weapon strength.

• Naruto: Shows his usual energetic admiration for Yao, proudly recounting Yao’s achievements and emphasizing their friendship.
• Uchiha Yao: Continues evolving from a talented young shinobi into an exceptionally powerful one. His Sage Body allows him to train the Mangekyō without the normal consequences, enabling rapid mastery of Susanoo.

Significant Themes

• Duty versus disillusionment: Tsunade’s refusal to become Hokage reflects her rejection of the village and the pain associated with her past, while Konoha’s crisis pressures her to resume responsibility.
• Inheritance and bloodlines: Yao’s Wood Release challenges established ideas about Kekkei Genkai inheritance and the division between Senju and Uchiha powers.
• Power and physical cost: The Mangekyō Sharingan is portrayed as a power that normally destroys its user, but Yao’s Sage Body alters that balance and allows him to develop it safely.
• Mystery and forbidden experimentation: Yao’s impossible combination of Uchiha heritage and Wood Release raises suspicion that his abilities may have a hidden or unnatural origin.
• Training and mastery: Repeated use transforms Susanoo from an unstable technique into a controlled, increasingly formidable weapon.

Important Character Interactions

• Jiraiya and Tsunade: Their conversation forms the central interaction. Jiraiya appeals first to Tsunade’s responsibility, then successfully uses her emotional connection to Hashirama and Wood Release to spark her interest.

• Tsunade and Yao, indirectly: Though they do not meet, Yao’s powers strongly affect Tsunade and become the main reason she considers returning to Konoha.

• Naruto and Sasuke: Become Yao’s temporary subordinates, placing him in a position of authority and responsibility over both promising Genin.
