Chapter Summaries

Shinji prepared to fuse the Super Blood Dragon Eye with the enhanced Red Eye and arranged for Karin, Haku, Neji, and Yakumo to provide Chakra if the process became difficult. After leaving the village and setting up in a hidden cave, he began the fusion.

• Neji asked Shinji to let him join the Akatsuki Organization, but Shinji refused because Neji was too weak.
• Yakumo eagerly agreed to Shinji's request to be ready to provide Chakra.
• Shinji contacted Karin, Haku, Neji, and Yakumo and planned to draw on their Chakra to support the fusion if needed.
• Three days later, Shinji summoned Meiqiu to impersonate him in his apartment and left the village.
• Shinji found a hidden cave, activated Susanoo, connected to the four Chakra sources through Naobi, and began the fusion.

Shinji began fusing the Susanoo Lamp with his Susanoo, using Magatsu to draw Chakra from Karin, Haku, Neji, and Yakumo as the process met fierce resistance. As the Susanoo’s eye sockets nearly aligned, fragments of intent emerged from the fused eyes and surrounded him.

• Shinji began the fusion and activated Magatsu to draw Chakra from Karin, Haku, Neji, and Yakumo.
• Karin, Haku, and Neji endured the Chakra extraction, while Yakumo resisted Ido’s pleas and agreed to hold on with her.
• Shinji received their Chakra and intensified his Dojutsu, bringing the Susanoo’s second and third pairs of eye sockets close to alignment.
• Ghostly fragments of intent emerged from the Super Blood Dragon Eyes and enhanced Red Eyes and circled Shinji, who watched them without reacting.

Shinji purified the Super Blood Dragon Eye and enhanced Red Eye of lingering fragments of thought, then forced their fusion to completion with Susanoo Lamp. He emerged with powerful new Red Pupils and began examining their abilities.

• Shinji used Magatsu to extract chakra containing fragments of thought from the Ketsuryūgan and Red Eye, sending it to Yakumo, where Ido devoured it.
• Yakumo collapsed from the chakra extraction, while the chakra nourished Ido in her mindscape.
• Shinji purified the eyes and drove Susanoo Lamp as the two pairs of Susanoo eye sockets overlapped but the fusion stalled.
• Shinji poured his remaining chakra and Dojutsu into Susanoo Lamp despite severe eye pain and bleeding from his eyes.
• The fusion completed, leaving brilliant Red Pupils in Susanoo’s second pair of eye sockets.
• Shinji discovered that the new Red Pupils surpassed Mangekyō Sharingan strength and began studying them.

Shinji created and named a new ocular Kekkei Genkai, the Red Dragon Eye, but its hidden Dojutsu resisted his control. After recovering from the fusion, he returned to school, where Shion noticed his fatigue and worried about Naruto's absence.

• Shinji examined the Red Dragon Eye, confirmed its enhanced vision, and found that its hidden Dojutsu resisted his control.
• Shinji considered ways to master the eye's power, then named it the Red Dragon Eye because of its defiant nature.
• Shinji returned to the village, collapsed from exhaustion, and slept until the next day.
• Shinji went to school and supervised Shion's training, and she noticed he seemed tired.
• Shion told Shinji she was worried because Naruto had been absent for several days and had stopped coming to school.

Shinji decided to transplant the newly fused Red Dragon Eyes into Yakumo before using White Zetsu Cells to cure her congenital frailty. After examining her with the eyes, he confirmed that her vital organs caused her condition and told her the transplant would begin soon.

• Shinji observed the students training and learned that Yakumo no longer needed daily checkups at the Medical Team.
• Shinji chose the Red Dragon Eyes for Yakumo, keeping Fugaku Uchiha's Mangekyō Sharingan and the Susanoo eyes for his other plans.
• Shinji slipped into the Kurama Clan's Main Family residence after confirming Yakumo's ANBU surveillance had been reassigned.
• Shinji examined Yakumo with the Red Dragon Eyes and identified problems in her heart, liver, and other vital organs.
• Shinji told Yakumo that her eyes were ready for transplant and that he would arrange the procedure soon, followed by a possible White Zetsu Cell transplant.

Shinji confirmed Yakumo could likely tolerate White Zetsu Cells and decided to give her a Red Dragon Eye transplant first. Meanwhile, Naruto pushed himself through intense Rasengan training until mental strain let the Nine-Tails’ chakra leak out, prompting Tsunade to watch over him.

• Shinji tested Yakumo’s cells, confirmed the village had stopped monitoring her, and chose to perform a Red Dragon Eye transplant before trying White Zetsu Cells.

• Jiraiya knocked Naruto unconscious while Tsunade caught him and confirmed that he was exhausted but his seal remained intact.
• Naruto tried to resume training, but Tsunade stopped him and decided to keep a close eye on him over the next few days.

Shinji transplanted the Red Dragon Eye into Yakumo and explained its abilities after it awakened her extraordinary vision. The eye also let Ido emerge from Yakumo’s inner world as a solid, visible Spirit Body capable of attacking directly.

• Shinji disguised himself, infiltrated the Kurama Clan estate, and began Yakumo’s eye transplant after strengthening her body with Karin’s Yang Release Chakra.
• Shinji quickly replaced Yakumo’s eyes with the Red Dragon Eye, and Yakumo opened them to discover she could see through walls and perceive chakra and blood inside people.
• Yakumo saw Shinji’s powerful Yin Release Chakra, prompting him to decide to conceal his own Chakra with a seal to protect his identity.
• Shinji told Yakumo that her new eyes were the Red Dragon Eye and described their abilities, including seeing through things, perceiving Spirit Bodies, and controlling blood.
• Ido emerged from Yakumo’s inner world as a solid, visible Spirit Body, revealing that she could now attack enemies directly.

Shinji realized the Red Dragon Eye let Ido form a powerful Spirit Body while Yakumo remained able to fight. After Ido disobeyed him and flew away, Shinji suppressed her and warned Yakumo and Ido that she could not leave Yakumo’s body without his permission.

• Shinji recognized that the Red Dragon Eye had strengthened Ido’s Spirit Body without leaving Yakumo’s physical body defenseless.
• Ido flew high above Konoha despite Yakumo ordering her to return.
• Shinji drained the Red Dragon Eye’s power, weakening Ido’s Spirit Body until she raced back to Yakumo.
• Yakumo and Ido knelt and begged Shinji to forgive Ido for disobeying him.
• Shinji spared them but ordered that Ido could not leave Yakumo’s body without his permission.

Shinji weighed the risks of strengthening Yakumo after Ido’s reckless behavior, then prepared to conceal his identity from her Red Dragon Eye. At Konoha’s training grounds, Naruto completed the Rasengan but collapsed from exhaustion, leaving Tsunade to believe he could become a great shinobi like his father.

• Shinji warned Yakumo that he would kill Ido and take back the Red Dragon Eye if she failed to control her.
• Yakumo demanded that Ido stop acting recklessly, and Ido returned to Yakumo’s inner world after promising not to challenge Shinji.

• Naruto used Shadow Clones to help him master the Rasengan after a week of training.
• Naruto collapsed from exhaustion after completing the Rasengan, and Tsunade told Jiraiya that Naruto might grow into a great shinobi like his father.

Shinji continued his cell-fusion research and realized that Tsunade was unlikely to take him as a medical ninjutsu disciple. At the Academy, he observed his experimental subjects before Sasuke challenged the entire class to spar.

• Shinji worked on experiments involving Yakumo and White Zetsu Cells, and Neji and Kimimaro's cells, while considering building his own laboratory.
• Shinji saw Tsunade force Naruto back into bed after Naruto claimed he had recovered, and noticed Naruto's bandaged, injured hands.
• Tsunade praised Shinji's medical talent but left without offering to teach him, disappointing his hopes of learning her Yin Seal.
• At the Academy, Shinji observed Karin adapting to blindness and Yakumo examining her surroundings with her newly acquired Red Dragon Eye.
• Sasuke easily kicked a student out of the sparring area and challenged the whole class, while Iruka noted that Sasuke's early-graduation application had received no response.

Sasuke overwhelmed most of his classmates in a sparring match before he and Yakumo cast Genjutsu on each other. Yakumo’s altered blood brought her back to her senses, while Sasuke became trapped in her illusion as the spectators wondered if he was under Genjutsu.

• Sasuke dodged and countered Kiba, Shino, Shikamaru, Choji, and Ino, then knocked down Sakura, Shion, and Hinata.
• Neji, Haku, Tenten, Rock Lee, and Shinji watched Sasuke’s display, while Shinji worried Yakumo might reveal her Red Dragon Eye.
• Sasuke found only Kimimaro and Yakumo still standing, then used the Body Flicker Technique to approach Yakumo and try to defeat her with Genjutsu.
• Yakumo turned to face Sasuke and formed Hand Seals before he cast Genjutsu on her.
• Yakumo’s blood flow jolted her back to her senses, while Sasuke saw an illusion of vines attacking him and dodged them.
• The training field fell silent as Yakumo gasped on the ground and Sasuke rolled away from imaginary attacks, prompting someone to ask if he was under Genjutsu.

Yakumo fought Sasuke in an Academy assessment, breaking free of his genjutsu but refusing to use the Red Dragon Eye or let Ido take over. As she sealed Ido inside her mindscape, Ido realized Yakumo had become far more powerful than she was and was learning to control that power.

• Sasuke realized Yakumo had trapped him in a genjutsu, then broke free by biting his lip.
• Kakashi and Asuma praised both students as Shinji watched Yakumo to see whether she would control the Red Dragon Eye and Ido.
• Yakumo wondered whether the Red Dragon Eye had helped her escape Sasuke's genjutsu, while Ido urged her to activate it.
• Sasuke attacked Yakumo with taijutsu and sent her flying, but she refused Ido's demands to use the Red Dragon Eye or take control.
• Yakumo sealed Ido inside her mindscape, and Ido realized Yakumo had gained more power and could now overpower her.

Yakumo endured Sasuke’s relentless taijutsu by dodging his vital attacks as the Red Dragon Eye secretly boosted her body, but Shinji stopped the fight before her frail body gave out. The students praised Shinji for stepping in, while he let them misunderstand what had happened.

• Sasuke attacked Yakumo repeatedly, but she avoided his vital spots and grew faster and stronger as the fight continued.
• Kakashi, Asuma, Neji, and Karin noticed unusual signs in Yakumo, though they mistook the Red Dragon Eye’s effects for a secret taijutsu technique or strange chakra.
• Sasuke activated his Sharingan and prepared a Great Fireball, but Shinji intervened, interrupted the ninjutsu, and rendered Yakumo unconscious.
• Shinji treated Yakumo and realized the Red Dragon Eye had been stimulating her blood and pushing her weak body toward collapse.
• Shion and Tenten praised Shinji for stopping the fight, and Shinji chose not to correct the students’ assumptions.

Yakumo woke at Konoha Hospital after her body was severely depleted, and Tsunade noticed that the chakra in her changed eyes had surged dramatically. Tsunade and Jiraiya investigated the mystery, while Shinji worried that Yakumo’s Red Dragon Eye had been exposed.

• Yakumo woke in Konoha Hospital, where Tsunade ordered her to rest and questioned her unexplained exhaustion and changed eyes.
• Shinji left the hospital, suspecting Tsunade had recognized Yakumo’s Red Dragon Eye and wondering how the village would respond.
• Tsunade told Jiraiya that Yakumo’s health had miraculously improved and that she had sensed the First’s Chakra within her.
• Tsunade showed Jiraiya Yakumo’s medical report, which recorded a nearly seven-hundredfold increase in chakra fluctuations in her eyes.
• Jiraiya suggested that Yakumo had awakened a new Dojutsu Kekkei Genkai rather than received transplanted eyes.

Tsunade and Jiraiya concluded that Yakumo had awakened a powerful new dōjutsu kekkei genkai, but her chronic frailty remained incurable by conventional treatment. After learning that a risky cell transplant might help, the Third ordered Tsunade to take Yakumo as her student.

• Tsunade judged Yakumo's eyes to be a newly awakened dōjutsu rather than transplanted organs, unaware that the Red Dragon Eye had masked signs of rejection.
• Jiraiya and Tsunade agreed to keep Yakumo's condition and new dōjutsu secret, then went to report to the Third.
• Tsunade told the Third that Yakumo's eyes might rival the Mangekyō Sharingan, and he ordered the information sealed.
• Tsunade explained that only a risky cell transplant might treat Yakumo's chronic condition, and admitted she was not confident she could perform it.
• The Third decided Tsunade should take Kurama Yakumo on as her student.

Tsunade agreed to take Kurama Yakumo as her disciple after the Third Hokage revealed Yakumo's talent and possible ocular Kekkei Genkai. Shinji learned of the arrangement at the Ninja Academy and saw it as an opportunity to gain information and learn Tsunade's Medical Ninjutsu.

• The Third Hokage explained to Tsunade and Jiraiya why Yakumo's talent could help keep Sasuke in check, and Tsunade agreed to ask Yakumo what she wanted.
• The Third Hokage brought Tsunade and Jiraiya to the Kurama Clan estate, where he told Kurama Murakumo and Kurama Ryō that Yakumo might have awakened a new ocular Kekkei Genkai and that Tsunade wanted to train her.
• Kurama Murakumo and Kurama Ryō agreed to let Tsunade take Yakumo as her disciple, and the Third Hokage ordered them to keep her Kekkei Genkai secret.
• Shinji heard his classmates say that Tsunade would take Yakumo as her disciple and concluded that the village had discovered the Red Dragon Eye.
• Shinji considered how Yakumo's apprenticeship could give him access to information from Konoha's leadership and a chance to learn Tsunade's techniques, including the Yin Seal.

Shinji made Yakumo’s apprenticeship under Tsunade her first mission after joining the Akatsuki Organization, directing her to use Tsunade’s expertise to develop the Red Dragon Eye and learn her techniques. Yakumo accepted the assignment while remaining wary of Danzo.

• Shion told Shinji that Naruto was training a secret technique with Jiraiya, and Sasuke overheard the news about the Sannin taking students.
• Sasuke grew angry that Yakumo had become Tsunade’s student and Naruto might become Jiraiya’s, believing he was no worse than either of them.
• At Konoha Hospital, Yakumo worried that Tsunade wanted her as a student because of the Red Dragon Eye and feared she might expose the leader’s secret.
• Shinji contacted Yakumo through Naobi and reassured her that Tsunade was not after the eye, warning her to watch out for Danzo.
• Shinji ordered Yakumo to become Tsunade’s student, cooperate with her to develop the Red Dragon Eye, and learn the Yin Seal and Superhuman Strength Punch.

Tsunade examined Yakumo’s newly awakened Red Dragon Eye and found that its perception and copying abilities surpassed those of the Byakugan and Tomoe Sharingan. The chapter ended with Yakumo demonstrating that she could seize control of Tsunade’s blood from a distance, prompting Tsunade to warn her about the danger.

• Tsunade brought Yakumo to a secluded training ground and asked her to activate the Red Dragon Eye.
• Yakumo activated the Red Dragon Eye, and Tsunade recognized it as an entirely new dōjutsu Kekkei Genkai.
• Tsunade tested the Red Dragon Eye’s observation, X-ray, chakra-sight, blood-perception, and copying abilities, finding them stronger than comparable Sharingan and Byakugan abilities.
• Yakumo told Tsunade that the Red Dragon Eye could control blood and increase her speed and strength.
• At Tsunade’s request, Yakumo used the Red Dragon Eye on her and briefly controlled her blood, but Tsunade broke free with Chakra and warned Yakumo to use the ability carefully.

Yakumo shared the Red Dragon Eye test results with Shinji while Tsunade and the Third assessed the eye’s power and classified its details as top secret. The chapter ends with Karin telling Shinji that both of her damaged eyes can now sense faint light.

• Yakumo coughed up blood but promised Tsunade she would not use the Red Dragon Eye recklessly, and Tsunade urged her to rest while promising to treat her.
• Yakumo returned to Konoha Hospital with a copy of the Red Dragon Eye test results, which Shinji viewed by connecting to her optic nerves with Magatsu.
• Shinji told Yakumo to accept Tsunade’s treatment plan, acknowledging that Tsunade might treat her more safely than he could.
• Tsunade gave the test results to the Third and Jiraiya, described the Red Dragon Eye’s power and hidden Dojutsu, and the Third ordered its details classified as top secret.
• After infusing Yakumo with Yang Release Chakra, Shinji asked Karin about her recovery, and Karin reported that both eyes could sense faint spots of light.

Karin’s damaged Mangekyō Sharingan showed its first sign of recovery, while Naruto challenged Sasuke at the Ninja Academy with a massive number of Shadow Clones. Naruto revealed the Rasengan during their fight, leaving Sasuke stunned as it reached him.
