Gather intelligence, determining enemy patrol ranges, and mapping the environment. Formulate a plan. Execute. Kill. Move.
Repeat.
For the weeks and months that followed, that cycle became the rhythm of Yuji and Sasori's existence on the battlefields of the Land of Grass.
They never stayed in one place long. Every few days, sometimes every few hours, they relocated.
Always moving, staying one step ahead of the net that Konoha was slowly trying to close around them.
The individual kills weren't dramatic. No major engagements.
Just steady, methodical elimination of Konoha's smaller units. Supply runners, messenger squads, patrol teams caught in transition between positions. Medical convoys moving wounded back from the front.
Small numbers each time.
But small numbers, compounded over weeks and months, stopped being small.
Before long, it wasn't just Konoha that had taken notice.
Word had spread to Iwagakure as well. Rumors filtered through the Stone's own intelligence channels about a three-man Sunagakure squad operating deep in Konoha's rear areas across the Land of Grass. Highly mobile. Difficult to pin down. And led, apparently, by two exceptionally young shinobi whose age belied their lethality.
On the battlefield, age was a meaningless metric. It didn't matter if a shinobi was nine or thirty. What mattered was whether they could kill you. And Yuji and Sasori had proven, repeatedly, that they could.
Neither Konoha nor Iwagakure was making the mistake of underestimating them anymore.
Half a year passed.
Six months of continuous field operations. Six months of sleeping in shifts, eating what they could scavenge, and never once letting their guard fully drop.
Yuji felt every one of those months in his bones.
The battlefield wasn't just dangerous because of the fighting. The fighting was almost the easy part, brief, intense, and then over. What ground a person down was everything else.
The constant vigilance. The awareness that every movement could be the one that tripped a trap or drew a hunter squad. The knowledge that Konoha's forces in the region were actively looking for them, and that the longer they stayed active, the tighter the noose became.
Their operational pattern demanded multiple layers of confirmation before any engagement. Scout the target, verify the intelligence, check for traps, confirm escape routes, double-check the escape routes. Only then move.
Even the simplest kill required hours of preparation. And every hour spent preparing was an hour spent exposed.
The Land of Grass wasn't large. That was the core problem. They'd been rotating through combat zones within the region to prevent Konoha's local forces from predicting their movements, but there was only so much ground to cover. The more time passed, the more data Konoha accumulated on their patterns. The more patrols adjusted.
If Konoha decided to invest serious resources into hunting them down, it wouldn't be difficult.
So the squad lived on a razor's edge.
A single missed detail could mean walking into a kill box.
And then there were the practical realities.
Supplies ran thin fast. A three-man squad operating independently in enemy territory couldn't carry much to begin with.
In the early weeks, they'd supplemented their provisions by looting what they needed from the dead. Soldier pills, kunai, wire, ration bars. The corpses of Konoha shinobi provided well enough.
But as time went on and their targets grew warier, the scavenging opportunities dried up. Missions became leaner. Engagements were faster, leaving less time to strip the fallen.
The mental strain was worse than the physical kind. Six months of never fully relaxing. Six months of sleeping with one ear open in whatever hole they'd dug or cave they'd found.
It wore on a person. Even a person like Yuji.
Inside a camouflaged cave, somewhere in the eastern reaches of the Land of Grass.
Yuji sat with his back against the rough stone wall, one leg stretched out, the other drawn up with his forearm resting on his knee. His special scalpel spun lazily between his fingers, catching the faint light from the cave entrance in dull silver flashes.
A habit he'd picked up over the past few months. Idle hands made him restless, and the repetitive motion gave his fingers something to do while his mind worked.
Beside him, Sasori sat cross-legged on the ground, surrounded by puppet components laid out with meticulous precision.
They'd spent enough time together now that Yuji had developed a genuine appreciation for what Sasori actually did.
Puppet mastery wasn't just about the ability to control puppets in combat. That was the baseline.
What separated a good puppeteer from a legendary one was the craft itself, the engineering, the design philosophy, the ability to build something that was more than the sum of its parts.
Sasori was in a class of his own.
Where another puppeteer might load a puppet with three or four mechanisms and call it complete, Sasori would arm the same frame to the teeth without sacrificing structural integrity or combat responsiveness. Every joint was engineered to support the weight and movement demands of the systems installed. Nothing was redundant.
From the largest articulated limb assembly down to the smallest wooden panel, Sasori knew every component of his puppets the way a surgeon knew the organs of the human body.
The materials he selected, the market availability of components suitable for puppet construction, the combat roles he envisioned for each puppet before a single piece was assembled were realized with almost disturbing precision.
It was, on some level, genuinely impressive.
Yuji could admit that much. Watching Sasori work on his puppets was like watching a master surgeon operate.
On some level, Yuji understood why Sasori called it art.
Because in a certain light, it was.
The parallel to medical ninjutsu wasn't lost on him either. A medical ninja's value wasn't just in the ability to perform techniques. The ninjutsu was the visible part, the flashy application that people saw and praised. But underneath that, supporting everything, was the knowledge.
Anatomy, Physiology, Pathology.
The deep, comprehensive understanding of the human body that made the difference between a competent healer and a genius one.
Sasori's puppet craft worked the same way. The jutsu was the surface. The engineering was the foundation.
And lately, Sasori had been digging into a foundation that hit very close to Yuji's area of expertise.
Human anatomy.
It had started as casual questions. Offhanded. Almost throwaway. But Yuji recognized the pattern immediately.
Sasori wasn't asking out of idle curiosity. He was building toward something specific.
Human Puppets.
Sasori could already create them, in a technical sense. He had the ability to convert a human body into a puppet shell. But the current results were cosmetic at best. They looked human. They moved like puppets. The distinction between a human puppet and a regular one was purely aesthetic.
What Sasori wanted was something that would make human puppets fundamentally different from wooden ones.
He wanted a core mechanism that could drive the puppet to perform the ninjutsu its original body had used in life.
And that meant understanding the mysteries of how chakra networks, tenketsu points, and living tissue actually functioned. How jutsu were channeled through a body. How the physical architecture of a human being translated into the ability to mold and release chakra.
The mysteries of life itself.
In that domain, Yuji was the expert. And not by a small margin.
Sasori had a foundation, built partly from Chiyo's teachings and partly from his own obsessive research. But it wasn't on the same level.
The gap between a puppeteer's understanding of the human body and a medical ninja's understanding was vast, and Sasori knew it.
So he asked. And Yuji answered.
Yuji was naturally happy to help Sasori create the 'puppet core' ahead of time... so the two would discuss and experiment privately whenever they were free.
Of course, all of the puppet core research happened behind Arai's back.
The captain didn't need to know. Wouldn't understand the significance even if he did. And more importantly, some things were better kept between the two people involved.
Yuji and Sasori had an unspoken agreement on that much.
"I've never been away from the village this long before."
Yuji said it to no one in particular, his voice carrying the dull weight of someone who had been living out of caves and ditches for half a year.
Beside him, Sasori didn't look up from his work. Puppet components clicked together in his hands with practiced precision.
"Judging by the recent momentum on the battlefield," Sasori said, his tone flat and analytical, "Iwagakure probably doesn't intend to fight Konoha to the finish. They'll pull back soon."
Yuji heard him but was already somewhere else in his head.
"I really want to eat Uncle Masao's rice balls," he murmured, licking his lips. "I've almost forgotten what they taste like."
Silence.
Sasori didn't even dignify that with a response.
"In the blink of an eye, we're both ten years old. Time really flies..."
Yuji sighed, tilting his head back against the cave wall.
"What is inside your head?" Sasori's voice was cold. "Don't forget, you're still on the battlefield."
"I know, I know."
Then, simultaneously, both of them went still.
A bird's cry from outside the cave.
Arai's signal.
Yuji responded with a low whistle, two short notes followed by one long. The all-clear reply.
A moment later, after confirming the exchange was genuine, Arai slipped through the cave entrance and crouched beside them.
"The village received word," he said without preamble. "Several of Iwagakure's rear front lines have already begun withdrawing."
Yuji and Sasori exchanged a brief glance.
It was the confirmation of what Sasori had already predicted. Iwa was pulling out.
The truth was, the only reason their three-man squad had survived this long in the Land of Grass wasn't just skill. It was information.
Intelligence shared between multiple villages, all of whom had a vested interest in making life harder for Konoha, had kept them one step ahead for six months. Sunagakure's own network provided the baseline. Iwagakure's battlefield intelligence filled in the gaps about Konoha's deployments. And beyond that, a steady stream of purchased intel from the underground black market had rounded out their operational picture.
The black market was one of the shinobi world's open secrets during wartime. Organizations and independent operators who made their living selling information to anyone willing to pay. No loyalty to any village. Just commerce.
It was one of the reasons the Land of Grass was crawling with foreign ninja and rogue operatives right now. Where there was war, there was profit.
But with Iwagakure withdrawing, that intelligence pipeline would dry up fast. And without it, operating in Konoha's backyard went from dangerous to suicidal.
"Is it about to end..." Yuji said quietly.
He'd expected this. The signs had been building for weeks. But hearing it confirmed still shifted something in his chest.
With Iwa pulling back, the open warfare between the major villages would narrow down to a single front. Kumogakure versus Konoha. Everything else was winding down.
And in the end, Iwagakure had failed to gain any meaningful advantage over the Leaf. Despite the scale of their commitment, despite the resources poured into the Land of Grass theater, Konoha had held.
A significant part of that was Orochimaru.
Yuji had never encountered the Sannin directly, and he intended to keep it that way. But the man's impact on the war was undeniable.
As a battlefield commander, Orochimaru hadn't just held the Land of Grass with personal power. He'd orchestrated defensive strategies, troop rotations, and counter-operations that had systematically neutralized Iwa's numerical advantages.
Looking purely at contributions to the village during this war, Orochimaru's role had been monumental.
A thought flickered through Yuji's mind, quiet and analytical.
'In the future Third War, he'll put in just as much effort. And it still won't be enough.'
Orochimaru would be passed over for Hokage. Despite everything he'd done. Despite the blood he'd spilled and the victories he'd secured. The position would go to someone else, someone brighter, more beloved, and trusted by the people.
And that rejection, more than anything else, would be what eventually drove Orochimaru out of Konoha entirely.
It was a cautionary tale. One Yuji had internalized long before he ever set foot on a battlefield.
Achievements alone weren't enough.
You needed the people behind you. You needed a reputation that went beyond fear and respect.
You needed to be liked. Trusted.
Seen as someone who belonged in that chair not just because of what you could do, but because of who you were.
Minato Namikaze understood that. Naruto, in his own clumsy, loud way, would understand it too.
Orochimaru never did.
Yuji's entire strategic approach to building his position in Sunagakure was, in no small part, modeled on the lesson of Orochimaru's failure.
Earn the achievements. But also earn the hearts.
Do both, or the chair would always belong to someone else.
"Let's move," Arai said, standing. His tone had shifted from informational to urgent. "Erase our tracks. The mission is officially over."
"Also, we need to leave ahead of schedule. Once Iwa withdraws and Konoha frees up resources from that front, they will absolutely redirect attention toward hunting down anyone still operating in their rear areas. That means us."
"Got it," Yuji said, pushing himself to his feet.
