Chapter Summaries

Uchiha Hikari challenged Sarutobi Hiruzen’s claims about the Uchiha and demanded greater integration between the clan and Konoha. She left the meeting seeking to build Uchiha alliances, aware that Obito and Black Zetsu still threatened the clan’s survival.

• Sarutobi Hiruzen argued that the Uchiha’s intense emotions and Sharingan made them vulnerable to hatred and darkness.
• Uchiha Hikari challenged Hiruzen by citing Orochimaru and Shimura Danzō as proof that non-Uchiha could also go astray, and condemned his defense of Danzō.
• Hiruzen proposed cautiously reviewing the Uchiha’s requests for more Military Police Force positions and jurisdiction and greater access to Anbu.
• Hikari demanded that Uchiha be allowed to serve as team-leading Jonin and Ninja Academy teachers and leave the village for missions, while other clans could join the Military Police Force under a three-party review.
• Hikari decided to become involved in Uchiha affairs because the clan remained threatened by Obito and Black Zetsu.

Uchiha Hikari warned Sarutobi Hiruzen about the surviving impostor calling himself Uchiha Madara and planned to investigate the Uchiha bloodline for ways to understand and control Sharingan evolution. The next morning, she met a young clan member named Izumi Uchiha.

• Uchiha Hikari warned Sarutobi Hiruzen that the man who triggered the Nine Tails Riot was still alive and could bypass Konoha's barrier, and Hiruzen agreed with his advisers to treat her intelligence as true.

• Uchiha Hikari considered tracing the clan's bloodline to its origin and finding ways to produce Mangekyō Sharingan or Rinnegan without emotional trauma.
• The next morning, Uchiha Hikari stopped a young girl delivering vegetables, who introduced herself as Izumi Uchiha.

Uchiha Hikari established her authority among the Uchiha and urged Fugaku and the elders to trade some Military Police Force power for greater influence in Konoha’s other institutions. She offered to train the clan and left them to decide whether to accept her plan.

• Uchiha Hikari followed Izumi to the Uchiha Compound, where Fugaku introduced her to the clan and several elders suggested she demonstrate her Mangekyō Sharingan.

• Uchiha Hikari offered to personally train the clan and asked Fugaku and the elders who agreed with her proposal and who opposed it.

Uchiha Hikari collected Uchiha blood samples for Dr. Brief to study the Sharingan and Mangekyō, then returned to the Dragon Ball World. She left Fugaku to negotiate with the Third Hokage and warned him about a masked man claiming to be Uchiha Madara, while Bulma pulled her into the lab to inspect a new weapon.

• Uchiha Fugaku gave Uchiha Hikari samples and records from seventy-one clansmen, including Mangekyō samples from Uchiha Shisui and himself, and confessed that he had secretly awakened the Mangekyō during the Third Shinobi World War.

• Dr. Brief asked Uchiha Hikari to help protect Bulma, and Uchiha Hikari agreed.
• Bulma took Uchiha Hikari into her laboratory to show her a new ultraviolet weapon.

Uchiha Hikari tested Bulma’s new inventions, visited Korin to learn about ki, and was offered a black Flying Nimbus before leaving. Korin’s cloud did not require a pure heart, but Hikari worried it might throw her off in midair.

• Bulma showed Hikari a Laser Sword, an Ultraviolet Protection Suit, and a Mini Bracelet, and mentioned an unfinished High-Energy Particle Gun.
• Hikari and Bulma agreed on a departure date for the Demon Slayer World, and Hikari flew to Korin Tower with entertainment gifts for Korin.

Uchiha Hikari traveled to the Demon Slayer world after Tanjiro accepted her request for help, arriving in the middle of a fight with Susamaru and Yahaba. She healed Tanjiro with half a Senzu Bean and confronted Susamaru, catching one of the demon’s temari balls barehanded.

• Bulma explained her research into sunlight and Nichirin Blades, and Hikari asked for the Laser Sword and Protective Suit to test.
• Hikari left the motorhome and headed toward the House of Demons, leaving her Shadow Clone to guard Bulma and Nezuko.

Uchiha Hikari tested a Laser Sword and Protective Suit while fighting demons in the labyrinthine house. She defeated the long-tongued demon and sealed Kyougai, but her blinding light also temporarily blinded Tanjiro and the others.

• Uchiha Hikari used her Laser Sword to wound the long-tongued demon, discovering that it slowed the demon's regeneration but did not kill it immediately.

• Uchiha Hikari spotted a giant demon at a settlement on a mountain plateau, activated her Protective Suit, and launched Falling Star Flash toward it.

Uchiha Hikari survived her Falling Star Flash with Bulma and fought Rui’s spider-faced “Dad,” but her remaining Chakra and broken blade limited her. She confronted Lower Moon Five, Rui, and ended the chapter beginning a Demonic Illusion technique against him.

• Uchiha Hikari landed amid the ruined stone houses with Bulma safe in her pocket, while “Dad” lay buried beneath the rubble.

• Uchiha Hikari challenged Rui over his fake family and asked what he took life for.
• Rui experienced Muzan’s fear through his cells and became too terrified to move as Hikari began Sun Breathing’s Seventh Form: Solar Bloom Thrust.

Uchiha Hikari disguised herself as Tsugikuni Yoriichi to terrify Muzan while defeating and sealing Rui. Afterward, Muzan mistook her for Yoriichi reincarnated as a girl and ordered Nakime to summon Kokushibo.

• Rui unleashed his Blood Demon Art, but Hikari cut through his threads and sliced his body apart with a Sun Breathing imitation laced with Amaterasu.

After dawn, Uchiha Hikari and Bulma returned from Spider Mountain and met Shinobu Kocho and Tomioka Giyu, who had been ordered to bring them before the Demon Slayer Corps Master.

• On the morning of the third day after the Spider Mountain incident, Kakushi escorted Uchiha Hikari, Bulma, and Tanjiro’s group to the Ubuyashiki Clan estate.

Uchiha Hikari met the Demon Slayer Corps Master and Hashira, offering information on the Twelve Kizuki in exchange for instruction in Breathing Techniques. After Sanemi demanded proof of her strength, Hikari demonstrated her ninjutsu and overwhelmed him in a spar.

• Ubuyashiki Kagaya introduced Hikari and Bulma to all nine Hashira and explained their role in the battle against Rui.
• Hikari clarified that she did not intend to join the Corps and offered either intelligence on the Twelve Kizuki or three miraculous healing pills in exchange for Breathing Technique instruction.

• After Shinazugawa Sanemi admitted defeat, Himejima Gyoumei asked Uchiha Hikari about her ninjutsu, and she demonstrated the Transformation Technique for the Pillars.

• Hikari suggested exchanging the swords for intelligent crows, crafts, toys, or objects tied to myths and legends, and Kagaya agreed to make a list.

Uchiha Hikari studied all ten Breathing Techniques and discovered that maintaining their Total Concentration Constant improved her Chakra refinement and elemental Ninjutsu. She considered combining the styles and planned to guide Tanjiro, whose growth had been delayed by her interference, while Uzui Tengen asked her to teach him ninja techniques.

• Uchiha Hikari asked Ubuyashiki Kagaya to summon Kuwajima Jigorou and warned him to investigate Kaigaku’s role in the deaths at the temple.
• Bulma examined Nichirin materials, while Tanjiro, Zenitsu, and Inosuke trained at the Butterfly Mansion with Shinobu Kocho and Kanao Tsuyuri.
• Uchiha Hikari used Shadow Clones to learn ten Breathing Techniques from the Hashira and Kuwajima Jigorou, then mastered their Total Concentration Constant.
• Uchiha Hikari found that Breathing Constants boosted Chakra refinement and matching elemental Ninjutsu, and she considered developing a combined Ten Breathing Styles.
• Uchiha Hikari realized Tanjiro and Nezuko had missed the growth they would have gained from fighting Rui, and she decided to guide them later.
• The Hashira reacted to Uchiha Hikari’s rapid progress, and Uzui Tengen privately asked her to teach him flashy ninja techniques.

Uchiha Hikari taught Uzui Tengen to use basic ninjutsu by supplying him with Chakra, while the Demon Slayer Corps investigated Kaigaku and tracked down the Upper Moon Six siblings in Yoshiwara. As the battle there reached its turning point, Hikari arrived and sealed Daki and her brother with ease.

• Uchiha Hikari gave Uzui Tengen Chakra and taught him the Three Body Techniques, which he learned to use imperfectly.
