Chapter Summaries

Uchiha Yu encountered young Uchiha Obito and his teammates, beat Obito after he caused a disturbance, and learned their team had been left without a leader. The revelation that Obito and Rin belonged to the “Forgotten Squad” left Yu shocked.

• Uchiha Yu recognized Obito and Rin, suspected White Zetsu might be watching them, and used his Omniscient Mind's Eye to investigate.

• The ordinary-looking teammate explained that Captain Shiomi had been transferred away and their squad had not received another leader.
• Uchiha Yu realized that Obito and Rin's team was the Forgotten Squad.

Uchiha Yu helped Rin’s team recover a white cat and spotted White Zetsu watching Obito, then focused on strengthening himself as the Third Shinobi World War approached. His intense training greatly increased his appetite, leaving Miwa Yashi to wonder how long his money would last.

• Miwa Yashi watched Uchiha Yu eat fifty pounds of meat and asked how long his money could keep feeding him.

Uchiha Yu struggled with the cost of feeding himself and Miwa Masayo, then learned that Uchiha Itachi had been born and began worrying about the Uchiha clan’s future. After defeating a transformed Heart Monkey, he discovered a new mental manifestation of his earth-element spleen: the auspicious beast Dangkang.

• Uchiha Yu and Miwa Masayo agreed to seek missions because their increased appetites had nearly exhausted his savings.

• A cry from the scattered white fur revealed a tiny tusked Dangkang, which Uchiha Yu recognized as the mental manifestation of his earth-element spleen.

At Uchiha Itachi’s Naming Ceremony banquet, Uchiha Yu learned from Miwa Masayo that Ninja Cats could sense his rapid cultivation changes, even though humans had not noticed them. He decided to keep his abilities hidden for now, judging that avoiding attention was more valuable than gaining access to clan resources.

• Uchiha Yu and Miwa Masayo attended Uchiha Itachi’s Naming Ceremony banquet and ate premium food that accelerated Yu’s Foundation Establishment.

• Yu let the sleepy Miwa Masayo rest and reflected that animals advanced by following their instincts while he cultivated through discipline and control.
• Yu weighed the resources and dangers of becoming a famous genius against staying unnoticed, and chose to continue hiding his changes.

After receiving a generous return gift from Uchiha Fugaku, Uchiha Yu settled into a routine of training and eating well while Miwa Masayo sparred with Kuromaru. His peaceful days ended when the clan assigned him to teach Uchiha Obito, leaving Yu to face an unwanted burden.

• Uchiha Yu received two hundred thousand ryō from Uchiha Fugaku and decided he might spare Itachi if doing so would not endanger anyone he cared about.

• A messenger told Uchiha Yu that Uchiha Obito had persuaded Uchiha Fugaku to arrange clan training for him.
• Uchiha Yu learned that Obito was the grandson of the late Elder Soramoto, Fugaku's former teacher, and that Yu had been selected because every other available ninja was occupied.

Uchiha Yu accepted the job of training Obito and used his claimed precognition to persuade Miwa Masayo that he could reveal the future. At the Naka River Training Ground, he began teaching Obito and his squad chakra control, ending in surprise at Obito’s clumsy attempt to climb a tree.

• Rin and the third genin climbed the tree successfully, while Obito ended up hanging upside down and struggling.

• Yu explained to Miwa Masayo that Obito had exceptional physical potential and that killing him before Uchiha Madara acted would let Madara choose another substitute.
• Yu said he planned to wait for Uchiha Madara to act and then make his scheme backfire, while Miwa Masayo became frightened by Yu's talk of killing Obito and making him feel grateful.
• Yu discovered that Obito concentrated when Rin had to share the punishment for his mistakes, and Obito's movements and training results improved sharply.
• Obito completed his exercises despite having no rest or meals, and Yu dismissed the three genin with a warning not to be late the next morning.

• Uchiha Yu had Obito, Rin, and Shinichi complete their training, and Shinichi and Rin each reached the top of the sixteen-meter tree.

• Uchiha Yu told Rin and Shinichi that the match showed the value of basic training, then sent the genin home to rest.
• The next day, Uchiha Yu taught Rin and Shinichi water walking while Obito trained; after Rin got wet, Yu put up a curtain to stop Obito staring at her.

After a week of special training, Rin and Shinichi improved their chakra control, but Uchiha Yu worried that Shinichi’s lack of access to ninjutsu would leave his talent undeveloped. The chapter ended with Obito demanding to know whether his special training consisted only of physical conditioning.

• Rin and Shinichi completed water-walking training and learned to cross the Naka River.
• Rin used several basic medical ninjutsu with ease and clumsily managed the Mystical Palm Technique, so Uchiha Yu urged her to study medicine before treating patients.

• Uchiha Yu praised Shinichi’s training and advised him to complete missions and earn merits to exchange for ninjutsu.
• Obito, doing squats while carrying one hundred kilograms, complained that his special training was only physical conditioning, and Uchiha Yu insisted that it was.

Uchiha Shisui joined Uchiha Yu’s training after showing exceptional talent, and Yu decided to make him the next clan head. Yu hoped Shisui would accept his ideals and lead the Uchiha clan away from destruction.

• Miwa Masayo celebrated her exchange with Fugaku, then noticed she and Uchiha Yu could no longer hear each other's thoughts once their chakra and Natural Energy transfer stopped.
• Miwa Masayo and Uchiha Yu resumed transferring energy and established minimum and maximum amounts that let them communicate through physical contact.

• The four students made rapid gains in strength, speed, endurance, and ninjutsu power, giving Yu greater authority to influence their values.
• Uchiha Yu found that Obito remained unaffected by his guidance because Obito's devotion to love outweighed concern for others, his clan, or the village.

• On the way home, Miwa Masayo worried she could not teach Senjutsu to the other cats, so Uchiha Yu explained how to create a safe cultivation room and train the Cat Sages.
• Uchiha Yu told Miwa Masayo that her earlier Senjutsu cultivation had been made possible by the concentrated fire-aspected Natural Energy he gathered while establishing his foundation.

• Uchiha Yu prepared the broth and layered the ingredients in a jar before setting it to simmer over a low flame.
• Miwa Masayo woke and stared eagerly at the simmering jar.

Uchiha Yu taught Shisui an advanced chakra circulation technique, then invited him home and built a closer bond with him. As they reached Yu’s neighborhood, its tense atmosphere and an accusation against Yu threatened to disrupt their walk.

• At home, Yu warned Miwa Masayo to watch the soup carefully, and she promised she would manage the fire.
• At the riverside training ground, Yu taught Shisui how to adjust his chakra circulation, explaining that mastering the technique would take years and that war was approaching.

• Uchiha Shisui worried that he had eaten too much, but Miwa Masayo explained that Uchiha Yu ate the bones and that the pile at Shisui’s place was not his fault.
• Remembering Uchiha Yu’s prediction about Shisui’s future talent, Miwa Masayo told him to extract Chakra and taught him to circulate it through his body without using ninjutsu.
• Shisui felt Chakra nourishing and strengthening his body, and Miwa Masayo advised him to train slowly and accurately.
• Miwa Masayo asked whether Shisui could afford meat twice a day, and Shisui said his family could pay for meals at the Akimichi family's Barbecue Garden.
• After twenty minutes of training, Shisui’s stomach felt better; he ate fruit before leaving Uchiha Yu’s home, becoming another big eater in Konoha.

• Uchiha Yu told Uchiha Shisui to share the Cat Sage's training method only with the clan head and a few elders, and reminded him not to abandon physical training.
• Over the next two days, Rin and Shinichi completed water-walking training, and Uchiha Yu taught them combat techniques while correcting dangerous movements.
• After Uchiha Obito failed water-walking fourteen times, Uchiha Yu strapped weights onto him and ordered him to run a lap around Konoha's walls.
• Uchiha Yu praised Uchiha Shisui's improving movements, then began testing his ability to extract and retain chakra.
• Uchiha Yu explained that chakra should be extracted steadily, stored, and used to nourish the body, rather than produced only through sudden exertion in battle.

Uchiha Yu explained why Shisui had to test his training methods before they could be shared, while Shisui recognized Obito’s remarkable talent and Yu dismissed his prospects because of his personality. After pushing Obito through exhausting exercises, Yu threw him into the river, where Obito discovered he could stand on the water and declared his training over.

• Uchiha Yu told Shisui that the new techniques might have flaws, so Shisui needed to find and fix them before they could be taught to others.
• Shisui watched Shinichi, Rin, and Obito train and noticed that Obito had developed an ideal weighted-running posture in only an hour and a half.
• Uchiha Yu insisted that Obito’s lack of resolve would prevent him from living up to his talent, despite Shisui praising Yu’s training.
• Uchiha Yu made Obito complete weighted squats and other exercises until he was exhausted, then threw him toward the river.
• Obito discovered that he could stand on the river and laughed that he had finished training and would no longer let Uchiha Yu torture him.
