The earth swallowed them before the screams could begin.
One moment, the Rain ninja were advancing.
The next, stone spikes erupted from the ground like a petrified forest, skewering bodies, pinning limbs, silencing the air with a wet, puncturing finality.
The Iwa squad didn’t bother with flashy techniques—just brutal, efficient geology.
The Rain Jonin’s face contorted, a mask of rage and ash.
“Now!” he roared.
His men shattered clay canisters at their feet.
Purple gas bloomed across the field, a toxic flower swallowing the Iwa ninja whole.
They choked, stumbled, collapsed into the mud.
Even the Jonin wobbled, their chakra systems seizing.
The Rain survivors rose from the carnage, eyes like shards of broken glass, and began their revenge.
Their swords rose and fell not with skill, but with a raw, shuddering hatred.
They weren’t fighting soldiers; they were butchering symbols.
From the tree line, the Senju watched.
A collective breath, held too long, escaped in a low hiss.
That poison would have dropped them, too.
The gas thinned, carried away by the borderland wind.
It left behind a tableau: a hundred Iwa bodies, still.
Twenty Rain ninja standing amidst them, chests heaving, blades trembling with exhaustion.
“Lady Tsunade,” Ryuichi’s voice was a gravelly whisper.
“The weeds are spent.
Time to pull the roots.”
Tsunade’s jaw tightened.
She gave a single, sharp nod.
Uchiha Ren scanned the horizon with his Sharingan—nothing but the chakra-emptiness of recent death.
He mirrored her nod.
The Senju descended.
It wasn’t a battle.
It was an execution.
The exhausted Rain ninja barely lifted their weapons.
Then one fell to his knees.
He was young, maybe sixteen, his face streaked with grime and tears.
He pressed his forehead into the bloody earth before Tsunade.
“Mercy!” The word was a cracked, desperate thing.
“Great Lady of the Fire Country, we had no choice!
Please!”
Tsunade’s step faltered.
Her hand, raised to strike, hesitated.
The boy’s eyes flicked up.
The despair in them crystallized, hardened into a pure, sharp hatred.
He moved—a desperate lunge, a long sword flashing upward toward her heart.
His chakra snapped out, a magnetic pulse rippling through the iron-rich soil.
[Magnetic Release: Sand Binding Coffin]
Dirt and sand erupted, not from the ground, but from the boy’s own clothes, from the blood on his skin, coalescing around him in an instant.
It wrapped his limbs, sealed his mouth, yanked the sword from his grip.
It left only his eyes visible, burning with that same, undiluted hate.
“You great nation devils!” The curse was muffled by the sand.
“Your hands are soaked in it!
You’ll drown in it!
Ha—”
Ren closed his left fist.
A wet, dense crunch, like a log snapping under a great weight.
The sand sphere darkened from brown to a deep, spreading crimson.
He flicked his wrist, sending the grotesque package tumbling into the distant ravine.
He didn’t let his eyes follow it.
He kept them on Tsunade.
The Senju around him shifted, a subtle settling of shoulders.
This was clean.
This was what a shinobi did.
Ryuichi stepped closer.
“My lady?”
Tsunade was staring at her own clean, unmarked hands.
“Are our hands… really that stained?” Her voice was too quiet for a battlefield.
The silence was answer enough.
“The stain isn’t the sin,” Ren said.
Every eye turned to him.
“The sin is the world that makes the stain necessary.
Yes, our hands are red.
We chose the red that keeps our home’s rivers from running with it.” He swept his gaze across the surviving Senju—the veterans with their grim acceptance, the younger ones with their pale, set faces.
“You pull the weed by the root.
Especially here.
Look around you.
We won.
We lost no one.
That is the only arithmetic that matters.”
A few of the older Senju studied him, their looks shifting from appraisal to a grudging respect.
The kid talked like a general who’d seen a dozen campaigns, not a clan outcast on his first real mission.
Tsunade inhaled, the scent of poison and iron filling her lungs.
Her spine straightened.
“You’re right.
I was… hesitating.
Forgive me.”
A chorus of reassurances rose from the Senju ranks.
Ren felt a strange, hollow pang watching them.
Such easy loyalty.
Such unquestioned unity.
The Uchiha would have been dissecting his technique, measuring his worth, calculating his threat.
Tsunade walked up to him, stopping an arm’s length away.
Her gaze was direct, stripped of its earlier confusion.
“Ren.
Your command of the field is instinctive.
From now on, you are this unit’s strategist.
In matters of tactics, even I will follow your lead.”
He had expected this.
The next move was more delicate.
“I accept.
On one condition.” He let his voice carry to the listening Senju.
“When we return to Konoha, the official report states all successes were under Lady Tsunade’s direct command.
My involvement stays here, in this forest.
All of you are witnesses to that secrecy.”
The atmosphere shifted.
The older ninjas understood immediately—this was a gift, and a shield.
It bolstered their princess’s prestige and protected this oddly capable Uchiha from inconvenient attention.
Their expressions warmed toward him, a silent gratitude.
“I can’t let you do that,” Tsunade protested, a flush rising on her cheeks.
“That’s stealing your valor.”
“It is preserving my utility,” Ren corrected gently.
He went to one knee, the gesture formal, decisive.
“This is my condition for serving as your strategist, Lady Tsunade.
Please.”
A middle-aged Senju with a scar across his chin stepped forward.
He placed a heavy, approving hand on Ren’s shoulder.
“The young master’s loyalty to the mission—and to you—is clear, my lady.
It would be an insult to refuse such a selfless offer.”
There it is, Ren thought, keeping his head bowed.
The smart one.
Under the collective, insistent gaze of her clansmen and Ren’s unwavering posture, Tsunade relented.
“Alright.
But I’ll remember this debt, Ren.”
Nominally, she remained the commander.
In truth, the unit’s direction passed to the Uchiha perched on Ryuichi’s back, his single tomoe spinning slowly as it scoured the landscape for the next threat.
They moved out, a silent, integrated machine.
And as the taste of copper and regret faded from the air, Ren knew the real poison wasn’t in the gas canisters.
It was in the choices that remained, waiting for them all further down the road.
