Chapter Summaries

Katsuo endured eye-pecking training and resisted Uchiha Izumi’s attempts to break his resolve, briefly showing signs of reaching Three-Tomoe Sharingan. After Izumi left, Katsuo learned that the dangerous training method had been discarded by Madara.

• Katsuo faced the young ninja hawk again and shouted that he was not afraid, despite the pain in his injured eye.
• Uchiha Izumi berated Katsuo and pressured him with his Three-Tomoe Sharingan, causing Katsuo’s Two-Tomoe Sharingan to spin as if nearing a breakthrough.
• Katsuo withdrew his Sharingan and declared that he could succeed if others could, and Izumi gave him medicine and instructions to continue training once a day.
• After Izumi left, Katsuo suspected that Izumi had lied about undergoing the training but decided to trust him and believed Madara had completed it.
• Uchiha Izumi asked Third Elder Uchiha Feng about the training, and Feng explained that it had been abandoned because it was dangerous and difficult, with Lord Madara responsible for discarding it.

Uchiha Feng explained to Uchiha Izumi that the ninja hawk training was meant to channel a child’s will into the eyes, not merely to strengthen will or killing intent. Katsuo continued his physical training at camp while Uchiha Feng went to meet Uchiha Sou.

• Uchiha Izumi learned that Uchiha Madara had undergone the harsh ninja hawk training twice before dismissing it as meaningless.
• Uchiha Feng told Uchiha Izumi that the training’s first step tested unwavering will and was especially suited to Katsuo’s age.
• Uchiha Feng explained that the training aimed to make each glance embody the trainee’s will through the Sharingan.
• Katsuo did push-ups with his eyes closed, avoiding the eaglet after it had pecked him.
• Uchiha Feng sent Uchiha Izumi away, then entered Uchiha Sou’s courtyard and met the Great Elder.

Uchiha Feng persuaded Uchiha Sou to treat Katsuo as a useful rival who could push Fugaku to improve, while disguising his own efforts to protect Katsuo and keep Fugaku away from Mikoto. After Feng left, Sou's advisers interpreted the visit as concern for Fugaku and Mikoto, unaware that Feng had placed his hopes on Katsuo.

• Uchiha Feng told Uchiha Sou that Fugaku needed a talented opponent to motivate him and that Katsuo could become a valuable Uchiha weapon.
• Uchiha Feng appealed to Sou by saying he did not want Mikoto to marry a weak man, and Sou agreed to supervise Fugaku's training and denied holding a grudge against Katsuo.
• Uchiha Feng left, satisfied that he had protected Katsuo, warned Sou against suppressing his branch, and discouraged Fugaku from pursuing Mikoto.
• Uchiha Sou asked his two jonin advisers why Uchiha Feng had visited, and they concluded that Feng was acting for Fugaku and Mikoto's future.
• Uchiha Sou accepted the advisers' interpretation, while Uchiha Feng's true intention was to give Katsuo time to grow stronger.

Katsuo endured weeks of eye training against a young ninja hawk and awakened his Three-Tomoe Sharingan. He began training with Old Duy, using medicinal baths to strengthen his body as he prepared for the coming war.

• Katsuo began body-tempering training with Old Duy, soaked in medicinal wine, and borrowed money through Uchiha Izumi to cover their meals and supplies.

• The Third Hokage sent Orochimaru and Tsunade to the academy, then warned Jiraiya that graduating Katsuo early would harm the five-year-old.

• A fifth-year Hyuga student used Eight Trigrams Sixteen Palms, but Katsuo blocked all sixteen strikes and assumed the Gentle Fist stance himself.

Katsuo defeated a group of students, including several Hyuga, with his taijutsu and ninjutsu before Orochimaru and Tsunade arrived. As Orochimaru became fascinated by Katsuo, Katsuo sensed his dangerous gaze and stared him down, bringing his Three-Tomoe Sharingan close to awakening.

• Jiraiya asked about Uchiha Katsuo's relationship with Uchiha Feng, and the Third Hokage summoned Feng to the Hokage Office.

• The Third Hokage confirmed that Katsuo would remain locked up for a few days and reminded Tsunade that Nawaki had also been involved, prompting her to threaten to discipline him.

While detained for attacking his classmates, Katsuo convinced the Third Hokage and the Sannin that his drive for strength came from losing his parents to war, and the Third Hokage released him after presenting the Will of Fire. As they left, Katsuo secretly revealed his Three-Tomoe Sharingan and vowed to stop relying on sympathy and pity.

• Katsuo reflected that he had chosen to align with Konoha rather than the Uchiha Clan, while still hiding his intentions behind a mask because he was weak.

• Tsunade examined Katsuo and found everything normal, while Jiraiya dismissed his complaint as a joke.

Katsuo’s body continued to weaken despite reduced training, so Tsunade examined him and Orochimaru took blood and tissue to investigate. After collapsing from a workout, Katsuo stopped training and told Might Duy he needed a few days of rest.

• Tsunade examined Katsuo with the Mystical Palm Technique but found no signs of illness, while Orochimaru asked for a blood sample and a piece of skin tissue.

• Might Duy encouraged Katsuo to balance training with rest, and Katsuo accepted that he could not continue body refinement for now.

Katsuo used shadow clones to train and continued developing a seal-less Fire Style technique suited to himself. He realized that fire’s nature transformation might be enhanced through temperature, but the technique remained unfinished.

• Katsuo created shadow clones and assigned them tasks to practice combat skills, Chakra control, and other techniques.
• Katsuo decided against copying the Rasengan or Lightning Cutter because he lacked the required Chakra nature and began developing a close-range Fire Style technique instead.
• Katsuo’s fire-playing shadow clone concluded that Chidori worked through outward Chakra flow and tested increasing the output of the flames in his palm.
• Katsuo rejected the stronger flames as ineffective and proposed skipping the explosive stage by directly enhancing Fire Style’s nature transformation.
• Katsuo and his shadow clone identified temperature as the key to that transformation, then Katsuo took the day off while his clones continued training.
