Day One – The Walk
Renji had been watching them for three weeks.
He had seen them fumble. Bicker. Laugh too loudly. He had seen sparks of leadership, flashes of raw talent — and just as often, moments of immaturity so sharp it was a miracle anyone survived training.
This three-day field exercise wasn't about strength.
It was about everything else.
Trust. Coordination. Who followed orders. Who broke them for the right reasons.
He stood quietly at the forest's edge, arms folded, watching as the students lined up for departure. Sunlight broke weakly through the morning mist. Packs were adjusted. Maps double-checked.
Then: Naruto yawned theatrically.
"We're not just walking for three days, right? There's gotta be traps or something."
Iruka didn't look up from his clipboard. "You're the explosion."
"Hey!"
Renji didn't smile.
But he almost did.
Naruto's first squad — Hinata, Shikamaru, and a lanky civilian-born boy named Tasuke — lost the trail twice, argued over leadership once, and still arrived at their checkpoint only six minutes late.
"See?" Naruto declared.
Shikamaru looked like he wanted to lie down and never move again.
Hinata had quietly done most of the navigating. She didn't brag. She just helped mark the path.
Renji, observing from a ridge, said only:
"Next time, listen faster."
Naruto's grin lasted a good fifteen minutes.
Ino's group — with Sakura, Kiba, and a quiet girl named Katsu — spent half the route arguing about direction.
Kiba claimed he could smell the way. Ino insisted "instinct" worked better than maps. Sakura threatened to throw the compass into a ravine.
Katsu, in the end, found a marker and rerouted them.
They arrived back at camp slightly bruised and slightly bickering.
Renji marked them down as: "Functional. Loud."
Camp – Night One
Camp was rudimentary. Simple lean-tos. Rough-cut tripwires made from wire and bells — just enough to signal if someone stumbled past.
There were no perimeter seals. Those were reserved for major outposts and strongholds — the kind of security that required teams of specialized shinobi to construct and maintain. Not something you could set up in the woods overnight with a dozen students and two chunin instructors.
Boiling the water took hours. Open fire, three shifts. Every canteen had to be purified to kill bacteria and parasites. No one had yet figured out a proper jutsu for it, and the water created by Water Release techniques, while clean, lacked essential minerals. It was good for washing. Useless for living.
Renji sat by the fire, checking gear tags while Iruka finished assigning the last two watches.
"You're watching them like they might explode," Iruka said.
"They're almost ready," Renji replied. "Some of them. Others are still trying to impress the wrong people."
Iruka sipped from a chipped tin mug. "They're eighteen. Impressing each other is how they think they survive."
Renji didn't answer.
But he didn't disagree.
Naruto's prank came later.
A scroll trap. A tripwire. And a terrified squirrel.
"It's called Operation Kaboom Sensei."
The squirrel got loose, bolted through Genki's tent, and caused what would later be known as the rice ball incident.
Renji confiscated the scroll.
"One hundred pushups."
"But I didn't even launch it!"
"Intent counts. And twenty more for misusing a squirrel."
Day Two – Shift
Morning came cold. Rotation changed. Squad Two now reported to Renji.
He pointed without ceremony.
"Hyūga. You're leading."
Hinata startled. "M-Me?"
"You know the terrain. You've been accurate. You're up."
She bowed faintly. "Yes, Sensei."
Her squad included Naruto, Katsu, and Choji. She began slow, checking the path three times before moving. She gave short, clear orders. When Naruto started rambling, she quietly reassigned him to carry half of Choji's gear.
They completed the loop ahead of schedule.
Renji didn't smile.
But he said, "Well planned," as they passed.
Her steps became more certain after that.
Genki twisted his ankle at the creek.
Renji appeared moments later.
"You're slowing your squad."
"I can keep up."
Renji crouched, pulled a bandage wrap and a small flask from his kit. The salve was cold and smelled sharp. Genki hissed.
"It'll numb the tendon. You'll be sore tomorrow. But it'll get you to camp."
He didn't offer to carry him. Just stood and extended a hand.
"Walk with me."
Genki nodded. Limped. Said nothing.
But he kept up.
That evening, the fire was warmer. The kids laughed easier. The work had drained most of their energy — and their pride.
They talked about childhood. Teachers. What they thought real missions were like.
Naruto tried to spin a story about outrunning a wild boar. Sakura elbowed him in the ribs.
Sasuke said nothing. But he sat closer to the group than he had before.
Ino passed Renji her bowl near the fire.
"Do I get a refill? Or do I have to earn it with flattery?"
Renji took the bowl. Refilled it.
Gave her a flat look.
She grinned. "That wasn't flirting."
He said nothing.
Just handed the bowl back.
The falcon came just before curfew.
Iruka read the message twice. Then handed it to Renji.
"Southern patrol's overdue. Last seen near Kawa ridge."
Renji scanned the scroll. "That's close. And rough."
Iruka nodded. "They have no one to send. No jōnin free. No team leads. Not even ANBU."
Renji was already adjusting his straps.
"I know the path. I'll check."
"You're not cleared for field engagement."
"I won't engage unless I have to."
"You don't want backup?"
Renji's eyes swept the fire — Naruto balancing a stick between his feet, Ino laughing at something Kiba said, Hinata quietly sketching the day's route in a notebook.
"No," he said. "I want them safe."
Iruka watched him for a long moment.
Then nodded once.
"Don't vanish."
"I won't," Renji said. "I still have paperwork."
Day Three – Fracture
Renji moved before the sun.
The woods were still and cool. No noise but breath and earth.
The signs came quickly: disturbed leaves. A blood smear on a rock. Drag marks.
Not fresh. But not old enough to forget.
He was crouched beside a scuffed root when he heard the whisper of steps.
He turned, instantly ready.
"You three—what are you doing here?"
Hinata. Ino. Naruto.
All three froze.
And then—
A shape dropped from the trees.
Armor from different sets. A half-broken Mist headband. A wild look. Bleeding from one arm. Desperate. Angry.
"You Leaf bastards don't give up."
Renji stepped forward. "They're students. Let them go."
"Already lost two to your scouts. Not letting anyone else talk."
Senbon snapped from his fingers.
Renji caught most with his blade — two embedded in his side.
He turned. More shuriken arced toward the kids.
"RUN!"
The students bolted.
Renji moved again, fast and hard.
He landed between the flying steel and the backs of his students, blade slashing, blood soaking through his vest.
He didn't falter.
He met the missing-nin's eyes.
Voice calm. Controlled.
"You want a fight?"
"Pick someone your own size."
