Half a month slipped by quietly amid a regular routine and intense mental activity.
Kyohaku Uchiha's life gradually settled into an almost rigid pattern. Every morning, he woke to the familiar soreness in his right leg, washed up, drank the milk delivered to him, and prepared a simple breakfast. In the mornings, if the weather was decent, he endured the discomfort and practiced the most basic throwing stances and methods of exerting force from his father's notes in the small courtyard, moving with extreme slowness. Naturally, he used that set of wooden ninja tools. Every attempt to steady his center of gravity, every adjustment to the balance between his crutch and body, came with fine beads of sweat and gritted determination. The afternoons were, without fail, reserved for the library.
The Konoha Library became his window into this world. He was no longer content with broad geography and history; he began gathering information systematically and purposefully. The professional habits from his past life as a forensic examiner resurfaced perfectly—observation, induction, classification, and building files.
He found large numbers of outdated or semi-public issues of the Konoha Ninja Mission Gazette, Analysis of the Shinobi World's Situation (Internal Reference), records of the customs and cultures of various countries, and even several biographies. Like a greedy sponge and a precision instrument, he devoured information madly and began constructing a vast, complex database in his mind.
[Macro Structure of the Shinobi World]
[Comparative Analysis of the Strength of the Five Great Nations and Their Hidden Villages]
[Konoha's High-Level Political Structure and Potential Factions (Hiruzen Sarutobi, Shimura Danzō, Mitokado Homura, Utatane Koharu...)]
[Current State and Historical Development of the Uchiha Clan (Focus: its estrangement from the village, the duties of the Konoha Military Police Force, personality analysis of major clan figures)]
[Intelligence on Notable Jonin (the Legendary Sannin, the White Fang, the Ino-Shika-Cho trio, the Hyuga clan head, and others... combat evaluations, personality tendencies, mission styles)]...
Information fragments were continuously gathered, assembled, and verified. He no longer viewed things through the filter of having read manga in his past life. Instead, he tried to reconstruct a real, cruel, and logically coherent shinobi world from cold text, data in mission reports, and indirect descriptions of people's words and actions.
As his understanding deepened, a cold and clear realization gradually took shape in his mind.
"What are shinobi?" Sitting in a cold chair at the library, he unconsciously ran his fingertips over the casualty figures from a border conflict recorded on the page. "Put simply, they're... assassins, spies, and special forces soldiers who wield the extraordinary power called chakra. Tools—the sharpest tools."
His gaze swept across the bustling crowd on Konoha's streets beyond the window, where children ran past laughing. "And the entire system of the Ninja Continent, as I see it, is more like a deformed, highly militarized mercenary market. Every hidden village is one of the largest mercenary groups."
He continued his analysis, comparing the characteristics of the major hidden villages as he tried to find corresponding models from his past life:
"Konoha," he mused, "is probably the one with the best humanitarian concern among them. It emphasizes the Will of Fire, protecting comrades, and has the Ninja Academy system. To some extent, it tries to raise 'tools' into 'people.' But at its core, it is still a mercenary base. It accepts commissions and funding from the Daimyō Court, provides military force to complete missions, and trades that for the resources needed to survive. Hiruzen Sarutobi... is like a patriarch trying to strike a balance between ideals and reality, mercy and ruthlessness, but he is probably often powerless to do so."
"Kumogakure," he recalled the style of the Land of Lightning described in the materials, "follows a completely militarist path. Its indoctrination is far more thorough than Konoha's. Absolute obedience to superiors' orders, worship of martial strength, missions above all else. If you fail a mission, you die; even in death, you must create value for the mission... This style is efficient, but also extremely cruel."
"Iwagakure," he compared it against the intelligence on the Land of Earth, "is somewhat like... North Korea from my past life? It follows a military-first policy. Shinobi hold the highest status in the country and receive the best treatment and resources. Everything good is supplied to shinobi first. This has resulted in an enormous number of shinobi. They speak of the 'Will of Stone' and are famous for human-wave tactics. Correspondingly, however, the average individual shinobi's equipment and ninjutsu may be relatively outdated. They place greater emphasis on group coordination and defense."
"Sunagakure and Kirigakure take the elite route. Sunagakure is forced into it by its environment. The Land of Wind lacks resources, so it must cultivate high-quality shinobi. Puppet Technique and poison are its specialties. Kirigakure... does not seem to have reached the most terrifying era of the Bloody Mist Village yet, but the signs of isolationism and cruel selection systems are already beginning to show. Every shinobi it produces is a vicious character."
Based on mission frequency, population size, wartime losses, and the rough public descriptions of each village's scale, he even began attempting quantitative estimates.
"Konoha currently has somewhere between ten thousand and thirteen thousand shinobi, judging by mission volume and personnel allocations," he calculated rapidly. "Among them, Jonin are the core elite and mission leaders, so there cannot be too many—probably around five hundred to seven hundred. Chunin are the backbone, handling most B-rank missions, and should number around three thousand. The remainder is the Genin population of more than ten thousand, including newly graduated academy students and the grassroots forces carrying out D-rank and C-rank missions."
"As for ordinary residents—including merchants, farmers, craftsmen, administrative personnel, and their families—there are probably more than a hundred thousand. By that measure, Konoha itself is a fairly large city, roughly comparable in scale and population structure to a prefecture-level city from my past life."
After reaching these conclusions, he felt a deep chill. This was no longer a passionate adventure story. It was a mixture of an immense, precise, ruthless war machine and social structure. Every shinobi was a cog in that machine, regardless of size.
And he, Kyohaku Uchiha—a disabled Uchiha orphan living alone away from his clan—was merely the most insignificant, most easily replaced and discarded cog among those tens of thousands.
If he wanted to survive, if he wanted to control his own fate, he had to possess greater value, or... become one of the people who controlled the machine.
He closed the book in his hands. Outside, the setting sun stained the library a dim yellow. The weight of knowledge pressed upon his heart, yet it also made his gaze sharper and clearer.
The more he learned about this real Shinobi World, the more he felt his own insignificance—and the clearer his path forward became: hide himself, accumulate strength, and then find an irreplaceable place in this cruel world of mercenaries.
