Chapter Summaries

Aoba secretly watched Minato develop the Rasengan, studying each attempt to learn from his process. Jiraiya caught him and brought him before Minato, where Aoba introduced himself as a Konoha Hospital medical-ninja intern.

• Aoba worked out Minato's training schedule and concealed himself to watch him develop a new chakra technique.
• Aoba observed Minato repeatedly form and lose control of a spinning chakra sphere, using his Chip to record and analyze the attempts.
• Jiraiya joined Minato, discussed the difficult technique, and protected him from a failed attempt with the Wild Lion's Mane Technique.

• Jiraiya confronted Aoba in his viewing tree, and Aoba apologized before introducing himself as a medical-ninja intern.
• Minato told Aoba that secretly watching someone train was not a good thing, while Jiraiya questioned whether Aoba was really a medical ninja.

Aoba proved his medical training and mastery of Tsunade’s Strength of a Hundred to Minato and Jiraiya, earning permission to watch Minato’s technique practice. After seeing Minato’s chakra ball explode when he tried to launch it, Aoba identified the technique he was attempting to imitate as a Tailed Beast Ball, leaving Minato and Jiraiya surprised by his knowledge.

• Minato questioned whether Aoba was really a medical ninja, and Aoba showed his hospital internship certificate and used Medical Ninjutsu.
• Aoba demonstrated Tsunade’s Strength of a Hundred, impressing Minato and Jiraiya and prompting Jiraiya to let him stay and watch.
• Minato tried to launch his stable chakra ball, but it lost its shape and exploded, forcing Jiraiya to shield them with Wild Lion's Mane Technique.
• Jiraiya gave Aoba a popsicle as the three rested beneath a tree.
• Aoba asked Minato whether he was trying to fire the chakra ball like a Tailed Beast Ball, then explained he had read about the beasts and their chakra attacks in Konoha Hospital’s archives.

Aoba explained to Minato that he should stabilize his chakra ball before trying to make it a long-range attack, helping Minato rethink his Rasengan development. Minato began focusing on stability, but by the third day the chakra ball still formed inconsistently and dissipated.

• Minato told Aoba that the Tailed Beast Ball had inspired him to develop a seal-less ninjutsu.
• Aoba demonstrated his Chakra Absorption Technique Version 2.0 on Jiraiya, but could absorb only a tiny amount of Jiraiya’s chakra.

• Minato began focusing on stabilizing the chakra ball, but it continued to explode or dissipate inconsistently.
• Jiraiya suggested refining chakra in the direction of a hair whorl, and Minato silently doubted the idea.

Minato completed a stable chakra sphere after Aoba’s suggestion helped him escape a dead end, and Jiraiya recognized the technique’s potential. Minato offered to teach Aoba a ninjutsu as thanks, but Aoba asked instead for Jiraiya’s hair technique.

• Minato thanked Aoba for his suggestion and offered to teach him a ninjutsu.
• Aoba declined Minato’s specialties and asked to learn Jiraiya’s hair technique, leaving Minato silent and looking toward his teacher.

Aoba chose Jiraiya’s hair-based ninjutsu to study and learned the basics of the Wild Lion's Mane Technique in a few hours. After hearing about rising tensions with Iwagakure, he began planning experiments to improve his sand control and stopped at a Nara herb shop.

• Aoba chose Jiraiya’s hair-based techniques, and Jiraiya enthusiastically agreed to teach him.

• Minato told Aoba that Iwagakure was unusually active and that Konoha’s jonin were preparing for missions.
• Aoba considered mixing hair, blood, nails, or cloned tissue with sand to improve his control, then entered a Nara herb shop.

Aoba used Jiraiya's Wild Lion's Mane Technique as a clue to improve his sand-control experiments. Blood mixed into sand let him control it with ease, and he planned to develop a scalable biological coating in the hospital laboratory.

• Aoba reasoned that hair's affinity for chakra might help him overcome sand's poor conductivity and high chakra cost.
• Aoba ground his hair and nails into powder, mixed them with sand, then added his blood to a second sample.
• Aoba found that the blood-infused sand resonated with his chakra and moved as easily as his own fingers.
• Aoba concluded that biological material containing his DNA improved sand control but sought a safer, more abundant alternative to his blood.
• Aoba considered growing his own cells into a biological coating for sand and decided to borrow the hospital's laboratory.

Aoba completed a successful first-generation Living Coating experiment before being summoned to an emergency operation for Namikaze Minato. Tsunade arrived but froze outside the operating room because of her hemophobia, leaving Minato's surgery in doubt as the crowd witnessed her trauma.

• The medical staff and onlookers realized that Tsunade's hemophobia had been exposed, while Minato remained in critical condition.

Tsunade overcame her blood phobia enough to direct the medical team treating Biwako, and Aoba assisted until the operation succeeded after twenty-three hours. Three days later, Aoba checked on Minato and Kushina, while Root learned that he had visited the Nine-Tails Jinchuriki.

• Ueno shielded Tsunade from the operating room and urged her to direct the treatment using her medical knowledge.

Sarutobi Hiruzen investigated Yamashiro Aoba after learning of his connections to Minato, Jiraiya, and Tsunade, while Danzo considered recruiting Kakashi into Root.

• Danzo read Aoba’s combat assessment and decided that his talent and business profits made him an ideal recruit for Root.

Aoba began carrying his chakra-infused sand gourd at the Ninja Academy, startling his classmates with its automatic defense and revealing to readers that it could also let him fly.

Aoba joined Minato, Akimichi Choza, and Aburame Shibi on an A-rank mission to Rōran to protect Sara and investigate the queen's disappearance. At the Land of Wind's border, Aoba used his sand to conceal the team as they prepared to cross the exposed desert.

• Aoba's medical work and earth-nature training strengthened his skills and let him control sand as an extension of his body.
• Minato recruited Aoba for an A-rank mission in the Land of Wind alongside Akimichi Choza and Aburame Shibi.
• Minato explained that the team had to protect Rōran's princess, Sara, and determine what had happened to the queen after contact was lost.

• At the desert border, Aoba swept up sand to raise a cloud of dust and hide the team from Sunagakure patrols.

Aoba used his sand to scout Rōran and learned that Anrokuzan had killed the queen and built a vast army of Puppets to control the Dragon Vein. As Minato and his team searched underground for Princess Sara, they found a blond boy wearing a Konohagakure forehead protector under attack.

• Aoba flew above Rōran and discovered that the citizens moving through its underground city were Puppets.

• Aoba used sand to pull Yamato from the Dragon Vein, and his Chip detected an encrypted electronic data packet in the energy.
