The air changed. Not violently. Not explosively. But undeniably. Even Kakuzu felt it. A shift in the battlefield itself, like something ancient had just stepped into the fight.
Shinji's hand moved through a seal before slamming against the ground. "Summoning Jutsu." Smoke burst outward across the clearing, thick enough to momentarily consume the battlefield. Then a figure stepped through it calmly, staff resting against his shoulder, sharp eyes already analyzing everything around him. Enma had arrived.
Kenta's jaw dropped immediately. "No way…" Aiko's eyes widened slightly as she stared toward the clearing. "A summoning…" Daiki stayed silent, but his focus sharpened instantly because this changed the fight completely.
Enma glanced around once before his gaze settled on Shinji. "You don't call me lightly." Shinji never looked away from Kakuzu. "I didn't." Enma followed his line of sight toward the Akatsuki member, his expression shifting subtly as understanding settled in. "I see… Good."
Kakuzu watched the two of them without visible concern. "Another body won't change the outcome." Enma's eyes flicked toward him coldly. "You talk too much." Even from the distance Kenta grinned slightly. "Okay… I like him already."
Shinji stepped forward slightly, his voice calm. "Enma… we're ending this." Enma tightened his grip around the staff. "Finally." Kakuzu moved first, the masks surging outward as fire and wind combined instantly while lightning gathered above them. Threads lashed across the clearing from every direction in a coordinated assault.
But this time Shinji didn't retreat. "Now." They moved together instantly, their coordination seamless like this had been practiced for years. Enma's staff expanded violently, smashing through the incoming flames and tearing apart the inferno through sheer force alone.
Shinji slipped through the opening immediately, closing distance on Kakuzu before the Akatsuki member could fully reset. Threads snapped toward him, but Enma intercepted first, spinning the staff through multiple attacks at once. "Stay focused!" Enma barked. "I am," Shinji replied calmly as he entered close range.
Shinji struck first, forcing Kakuzu to block, but Enma followed immediately behind him. The staff slammed into Kakuzu's side hard enough to drive him backward across the clearing. He landed while sliding through cracked earth before finally stopping. For the first time there was visible resistance in his movement.
"Two of you…" Kakuzu muttered. "Better." From the distance Aiko narrowed her eyes slightly. "The pressure shifted…" Daiki nodded slowly. "Sensei's not being contained anymore." Kenta grinned. "Yeah… now it's starting to look unfair."
Kakuzu's threads expanded again, more aggressive now, more violent. But Shinji and Enma never separated. Every attack Kakuzu launched was met with an answer, every opening punished instantly. Enma controlled the battlefield itself while Shinji operated inside the chaos with terrifying precision.
One of the masks unleashed lightning directly toward Shinji, but Enma intercepted instantly, redirecting the strike into the ground. The explosion shook the clearing as smoke burst upward everywhere. Shinji emerged from it already moving, his strike slamming directly into Kakuzu's torso. The impact forced Kakuzu to stagger slightly.
"You've improved," Enma said quietly. Shinji didn't answer, but his Mangekyō Sharingan burned brighter now, active and watching everything. Kakuzu noticed immediately. "…So this is your real level." Shinji stepped forward slowly. "Not yet."
The pace of the fight accelerated again. Kakuzu pushed harder, multiple masks attacking simultaneously while threads weaved between them in increasingly complex patterns. Fire, lightning, and raw physical force layered together relentlessly. But now Kakuzu wasn't controlling the battle anymore, he was reacting to it.
Enma moved like a force of nature, his staff crushing through attacks and breaking Kakuzu's rhythm repeatedly. Shinji followed every disruption perfectly, turning each opening into another precise strike. Then it happened. Kakuzu shifted his defense toward Enma for a fraction of a second and left himself exposed.
Shinji saw it instantly. The Mangekyō sharpened as his movement blurred forward. His strike landed cleanly through Kakuzu's guard, and for a split second the battlefield fell silent. Then one of Kakuzu's masks shattered violently in a burst of chakra.
Daiki's eyes widened slightly. "He destroyed something…" Aiko nodded slowly. "Not just damage." Kenta leaned forward, staring at Kakuzu. "He took something from him…" Kakuzu stepped back slowly, his hand moving toward his chest where the destroyed mask had been.
For the first time his expression changed. Not fear, but recognition. "So that's how it is…" he muttered. Enma glanced toward Shinji and finally saw it clearly now: the control, the precision, the Mangekyō, the presence. A single thought crossed his mind. This boy has surpassed Hiruzen.
Shinji stood there breathing steadily, eyes locked onto Kakuzu. "You're not leaving with that bounty." Kakuzu straightened slowly, threads tightening around his body once more, but now he was cautious. Measured. "…We'll see."
Kakuzu stood still for the first time since the battle began. Not attacking. Not advancing. Thinking. Three hearts remained inside his body, and across from him stood Shinji Uchiha and the Monkey King Enma. The battlefield itself felt tense now, like the forest understood something decisive was about to happen.
The air had grown heavier. Not from killing intent, but from something deeper. Something building beneath the surface of the fight itself. Shinji exhaled slowly as the Mangekyō pulsed within his eye, his vision flickering slightly at the edges from the strain. He could feel the cost already building inside his body, but this needed to end now.
Kakuzu moved first. Not recklessly, but with full commitment. Threads surged outward while the masks attacked in perfect coordination, lightning crashing down from above as fire and wind tore through the clearing together. It wasn't probing anymore. It wasn't testing. It was a kill attempt.
"Stay sharp!" Enma barked as his staff expanded violently, smashing through an incoming wave of flames before they could consume the battlefield. "I know," Shinji replied quietly. But there was something different in his voice now, something deeper and more focused than before. Then he stepped forward, and the world itself changed.
It wasn't visible at first. The shift wasn't dramatic or explosive. But Kakuzu felt it instantly. Space around him tightened unnaturally, forming an invisible sphere no larger than three meters wide. Small. Compact. Absolute.
Kekkai Ten'i.
The domain formed around Kakuzu completely, and suddenly his movement slowed. Not stopped, but resisted, like the air itself had gained weight and begun fighting against him. "…What is this…" he muttered as his stance faltered slightly. Shinji's right eye pulsed hard, blood tracing slowly down his cheek.
"Jūryoku Enatsu."
The pressure crashed downward instantly. Violent gravity slammed into Kakuzu hard enough to crater the ground beneath him as his body dipped under the force. "…Ghh—!" The black threads reacted immediately, trying to stabilize him, but even they slowed under the crushing pressure dragging against them.
From the distance Kenta felt it immediately. "…Why does it feel like everything just got heavier…" Aiko's eyes widened as she stared toward Shinji. "…He's controlling the space itself…" Daiki stayed silent, but he understood exactly what this meant. Shinji was finally going all out.
Even Enma went silent for a moment as he watched the battlefield shift again. Then chakra began forming around Shinji's body. Golden energy flickered outward at first in incomplete skeletal shapes before rapidly solidifying into something undeniable. A Susanoo.
Yellow skeletal armor wrapped itself around Shinji, towering over the battlefield with overwhelming presence. One arm carried a spear while the other formed a shield of condensed chakra. Kenta's voice dropped almost instinctively. "…What… is that…" Aiko didn't answer because she couldn't. Even Daiki had no words left.
Enma's grip tightened slightly around his staff as his eyes narrowed. The domain. The gravity manipulation. The Susanoo. The precision required to control all of it simultaneously. That thought crossed his mind again, clearer now than ever before. He's surpassed Hiruzen.
Kakuzu struggled against the pressure surrounding him. His movements had slowed drastically while his masks destabilized under the domain's influence. "…You…!" he growled, but it was already too late. Shinji moved, or rather, the Susanoo did.
The massive construct stepped forward once, and the ground shattered beneath its weight. Then the spear came down. Fast. Precise. Completely unavoidable within the confines of the domain. Kakuzu tried to move, tried to shift around the attack, but the gravity held him in place just long enough.
Impact.
The spear drove cleanly through him with devastating force. For a single moment the battlefield went completely silent. Then two of Kakuzu's masks exploded outward simultaneously in violent bursts of chakra.
Kakuzu's body jerked violently as the destroyed hearts disappeared completely. Three hearts gone. Only one remained. The domain faded moments later as the crushing pressure finally lifted from the battlefield, and Shinji's Susanoo flickered before disappearing entirely.
Shinji staggered once. Barely noticeable, but real. Blood continued running from his eye while his breathing grew slightly heavier, though still controlled. Across from him Kakuzu landed hard against the ruined ground, his body barely holding itself together anymore. One heart. One chance.
Kakuzu looked toward Shinji first, then toward Enma standing untouched nearby with his staff already lowering back into position. A calculation formed instantly in his mind. Could he still win? Maybe, if Shinji stayed weakened long enough. Maybe, if he pressed immediately.
Then Enma shifted slightly.
That alone answered the question.
No. Not worth it.
Kakuzu stepped backward slowly as his threads pulled inward to stabilize his damaged body. "…You're not worth dying for," he said flatly. Shinji didn't move. Didn't chase him. He already understood the fight was over.
Space warped slightly before Kakuzu vanished back into the forest completely. Gone.
Real silence settled over the clearing for the first time since the battle began. Then the tension finally broke. Kenta dropped onto the ground immediately. "…YEAH—okay—no one tell me that was normal." Aiko exhaled deeply beside him. "…We survived." Daiki kept his eyes on Shinji. "…We won."
Shinji stood still for another moment, letting his chakra settle and the strain pass through his body before finally speaking. "…We completed the mission." Simple. Final. Enma glanced toward him before giving a faint huff.
"You've grown."
Shinji gave a small nod. "…So have the stakes."
Enma smirked faintly at that. "…Next time, call me sooner." Then smoke burst around him as the Monkey King disappeared from the battlefield entirely.
The team regrouped afterward without even realizing it. Closer now. Not spread apart like before. Together. Kenta looked at Shinji differently than he had at the start of the mission. "…Sensei…" He paused briefly before shaking his head. "…You're insane."
Aiko didn't disagree. "…That power…"
Daiki finished the thought quietly. "…You trusted us enough to hold the line."
Shinji looked at them carefully for a moment. Really looked at them. "…You did more than that." A brief pause followed before he continued. "…You adapted."
Kenta smirked slightly. "…We asked for help too."
"…Eventually," Aiko added.
Daiki allowed himself a small breath. "…And it worked."
Shinji turned back toward the road ahead. "…Then remember that." His voice remained calm, but firm enough that all three of them understood the weight behind it. "…Because next time, it won't be this controlled."
They moved out together soon after. By sunset the caravan reached its destination safely, the mission completed successfully without further incident. But that night something had changed within the team itself.
For the first time since their formation, they didn't just feel like a team anymore. They knew they were one.
Kenta laughed louder than usual around the campfire while Aiko finally relaxed enough to stop monitoring everything around her every second. Daiki no longer carried every responsibility entirely on his own shoulders. And Shinji simply watched it quietly from a short distance away.
Because this was what he had truly wanted all along. Not just strength. Not just power. But something that lasted beyond the battlefield.
