Chapter Summaries

Ruri assigned Kakuzu to manage the Shinobi World Library and oversee a shinobi world encyclopedia that would organize knowledge from across the world. When Kakuzu worried about keeping the encyclopedia current, Ruri showed him a publication called United Nations Weekly.

• Kakuzu examined a rubbing about the origins of Puppet Theater and asked Ruri about the library’s collection of eighty million volumes.
• Ruri told Kakuzu that the library was his to manage, adding that Linglong would work nearby as the daimyo of the Land of Waterfalls.
• Ruri tasked Kakuzu with organizing an encyclopedia covering chakra training, ninjutsu, records, literature, and professional experience.
• Kakuzu questioned whether making ninjutsu widely available would weaken shinobi who had developed original techniques, and Ruri explained how grading and talent would address the concern.
• Kakuzu worried that the encyclopedia would become outdated as ninjutsu and technology advanced, so Ruri showed him United Nations Weekly.

Ruri established United Nations Weekly as a research journal that rewarded accepted submissions with mission pay and experience, and Kakuzu saw a new way to profit from his research. After submissions began arriving, Dodai’s research on a durable new type of rubber impressed Ruri and offered a promising material for ships and other machinery.

• Ruri explained to Kakuzu that United Nations Weekly would publish research and reward accepted submissions with mission pay and mission experience.
• Kakuzu worried about the cost of the rewards, then agreed to serve as an evaluator and considered submitting his own research anonymously for manuscript fees.

• Dodai submitted a lengthy analysis describing a durable rubber made with Lava Release that resisted heat, cold, water, and impacts.
• Ruri recognized Dodai’s rubber as a promising material for ships, machinery, and buildings, and anticipated that studying it could eventually enable industrial production.

Ruri reviewed the research submissions, including Minato’s findings that compressing chakra could increase a ninjutsu’s power, and suggested that the principle might enable Scientific Ninja Tools. She also learned how Might Duy’s teaching experiments led Konoha to develop a movie camera, while suspecting Konoha had publicized its research to strengthen its standing in the United Nations.

• Minato studied the Rasengan and Tailed Beast Bomb with Kushina and concluded that compressing a ninjutsu while preserving its chakra could increase its power.

• Ruri explained that the university would offer genin four years of study before evaluating them for promotion, while experienced jonin would teach.

• A proposed an affiliated Shinobi World United Nations School to train genin and accommodate exchange students using Takigakure's educational methods.

After Hidan and Hanzaki recognized Kabuto as the author of a chakra research submission, they carried him off to meet Hidan’s sister and the others, leaving Kabuto hopeful that his work had been accepted.

• Hidan endured Fuma Hanzaki’s attacks and incessantly urged him to worship the First Takikage, prompting Hanzaki to regret agreeing to spar.

The magazine became a hit, and Kakuzu and Crimson Lotus enjoyed the rewards of their successful work as the shinobi world moved toward peace.
