History

Ninja Village Era

The Ninja World was originally divided among major and minor Ninja Villages, whose ninja clans competed for influence while feudal lords supplied funding and exercised political authority. The village system replaced the Warring States Period's clan conflicts, but did not end the cycle of war; tailed beasts became military weapons, and repeated Ninja World Wars followed 92.

Its conventional training structure was fragmented. The Ninja Hospital offered basic theory and training, but advancement from Chunin through Jonin and Elite Jonin lacked a unified standard; strength and opportunities depended heavily on missions, clan inheritance, and bloodlines 59.

Konoha's Rise and the Fourth Ninja World War

After becoming Fifth Hokage, Naruto/Xuanming establishes the Konoha Alliance and begins extending Konoha's influence through infrastructure, resource extraction, and military organization 56. His stated objective is to end the Ninja Village era by unifying the world under Konoha rather than preserving Hashirama Senju's balance of competing villages 82 92.

The Five Kage Summit collapses into open hostility when Naruto refuses to submit to the other Kage's demands. The Land of Iron abandons neutrality and joins the opposing camp, setting the Fourth Ninja World War in motion 92.

Konoha and its allies win the war. Naruto announces that the surviving villages will be absorbed into the Konoha Alliance, while Combat Ninja Force units called the Shadow Division spread across newly annexed territories 133.

Formation of the New Ninja World

Naruto declares Konoha the world's only main Ninja Village; former villages may retain branch names but must recognize him as the sole Kage. Feudal lords remain responsible for funding their regions, while Konoha takes control of strategic resources, railways, ports, shipping, and industrial development 134.

The former Five Kage are reduced to regional leaders of the Combat Ninja Force and answer directly to the Hokage of the Ninja World 137. Ninjas who refuse the new order are classified as rogue ninja or rebels 135.

The postwar world undergoes mass resurrection, increasing Konoha's population fivefold and forcing major expansion projects. Hashirama and Madara use Wood Release to support construction, while former ninja and civilians struggle to adapt to changed families, careers, and social roles 145.

Sage Art Era

Naruto creates Sage Towers across the Ninja World to prepare humanity for a future Otsutsuki invasion. The towers offer a common cultivation path that can improve physical ability, chakra capacity, techniques, bloodlines, and longevity 153.

Traditional ninja ranks and clan monopolies gradually lose importance as more people focus on Sage Art cultivation. The Chunin Exams become a commemorative event rather than the central measure of a ninja's advancement 223.

Timeline Separation and Universal Merger

At the pseudo-sixth level, Xuanming separates the Sage Art Ninja World from the original timeline and resets the latter. The separated world gains an independent future, while the reset timeline continues without Naruto's direct intervention 214.

In the reset world, the old cycle of village wars resumes. Konoha eventually disappears, resources are depleted through recurring conflict, and the world regresses toward a new Warring States-like era 216 219.

Later, Naruto restores lost memories, fuses the entire Ninja World universe into one, and becomes its governing will, able to determine its future time and space 235.

Government & Administration

Era	Political arrangement
Ninja Village Era	Independent villages, clan factions, and feudal lords share authority; each village maintains its own military traditions and interests 59 92.
Konoha Alliance	Konoha forms alliances with villages such as Sunagakure, Amegakure, Kirigakure, and Otogakure while building centralized military departments 114 120.
New Ninja World	Konoha becomes the sole main Ninja Village; all former villages become branches under Naruto as sole Kage 134.
Regional Combat Administration	Former Kage lead regional Combat Ninja Forces but remain subordinate to the Hokage of the Ninja World 137.

Society

Ninja Clans and Commoners

The New Ninja World weakens the old clan hierarchy by allowing ordinary ninja to earn merit and exchange it for ninjutsu, Kekkei Genkai, bloodlines, and access to chakra experimentation pods 77 157.

• Techniques such as Scorch Release and Dust Release become exchangeable rewards rather than exclusive inherited powers 77.
• Chakra pods are intended to make the entire population capable of becoming ninja 133.
• Bloodlines gained through exchange can be inherited by descendants 157.
• The Byakugan, Sharingan, Shikotsumyaku, and Uzumaki chakra are all presented as obtainable rather than clan-exclusive powers 157.
• The Hyuga Clan abolishes the Caged Bird seal on resurrected members 145.

Combat Ninja Force

Naruto creates centralized forces independent of the old village-clan model. Their members are trained, modified, and equipped through Konoha's systems rather than relying solely on hereditary techniques 120 122.

• Shadow Division — Combat units established in former villages after the Fourth Ninja World War 133.
• Explosives Unit — Led by Deidara 120.
• Puppet Unit — Led by Sasori 120.
• Hokage Guard Unit — Led by Yamato, with Neji Hyuga and Sai as members 120.
• Academy of Sciences — Provides technical support and counters abnormal forbidden techniques under Kabuto 120.

Science, Industry, and Entertainment

The Academy of Sciences drives the Ninja World's industrial transformation.

• Railways, oil extraction, tree-planting projects, factories, and regional science bases are ordered during Konoha's expansion 56 134.
• Roads, highways, and rail networks eventually reach distant regions, including formerly isolated mountain areas 146.
• Kumogakure develops airports and explores aircraft powered by propellers, Wind Release, Fire Release, or passenger chakra 146.
• Wireless networks, game consoles, mobile phones, manga, online novels, and games become widespread after the war 191.
• The moon is hollowed out and converted into humanity's first major space base 149.

Sage Arts & Cultivation

Sage Art is the New Ninja World's universal cultivation system. Naruto presents it as both a route to individual growth and a collective defense against the Otsutsuki Clan 153.

• Sage Towers stand throughout the world, including in former villages 153.
• The towers are living beings created by Naruto; Sage Art practitioners become part of his Sage Clan 153.
• Cultivation can grant enhanced bodies, extensive chakra, access to natural sage chakra, varied chakra natures, space-time techniques, secret arts, and fused Kekkei Genkai 153.
• The standard growth cycle is to cultivate, complete missions, earn merit, exchange for techniques or bloodlines, and repeat 157.
• Sage Art draws in former rogue ninja, many of whom seek qualification to cultivate in exchange for clearing their crimes 154.

Major Locations

• Konoha — The sole main Ninja Village after unification and the political center of the New Ninja World 134.
• Sage Towers — Global cultivation structures that provide the fifteen-level Sage Art path 153.
• Academies of Sciences — Research centers responsible for chakra pods, industrialization, technology, and scientific ninja tools 56 120.
• Moon Interior — A hollowed-out lunar space transformed into a super base and future staging point for space exploration 149.
• Former Ninja Villages — Retained as named branch regions under Konoha's centralized authority 134.
