The staging area sprawled across Training Ground Four like a military encampment waiting to happen. Shinobi in loose formations, equipment checks creating a rhythm of metal and cloth, the place reeked tension that preceded any large-scale operation, even when it was only practice.
The Hokage had ordered the readiness assessment three days after the Kumo intelligence briefing. No official explanation given, but explanations weren't necessary. Everyone who'd heard the rumors about Lightning Country's military buildup understood. The village wanted to know where it stood.
Not everyone was present. ANBU squads remained deployed along the borders. Several teams were mid-mission in various countries. A handful of jonin were scattered across assignments deemed too critical to recall. Missions didn't pause for exercises, and exercises didn't pretend otherwise.
Tatsuya found station three and started arranging supplies. Tourniquets within arm's reach. Suture kits in the secondary pouch. The routine was familiar, quieting the part of his brain that wanted to catalog every tactical formation visible across the field.
"Meguri." A woman settled beside him, hands sorting her own kit by touch alone. Late twenties, dark hair pulled back efficiently, expression suggesting she'd stopped being impressed years ago. "Station three. Lucky you."
He glanced at her. "What's significant about station three?"
"Best sightlines." She didn't look up from her supplies. "Tsunade-sama puts people here when she wants to watch them work." A pause. "I'm Rika. Section Seven. We've crossed paths."
"Circulation case. Three weeks ago."
"The one where you told me my approach was suboptimal." Her tone was flat. "Yeah. That one."
"I said your technique could be refined." A pause. "There's a difference. I think."
"Is there." Not a question. But her posture shifted, less hostile, more assessing. "Don't let the sightlines rattle you. Just... do what you do."
Taro arrived carrying the secondary supplies like they might explode. Yamamoto's apprentice, younger, still learning where the confidence came from. He nodded at Tatsuya with more wariness than welcome.
"Heard about Grass Country," Taro said. "Sora's leg."
"Yeah."
"She's walking. They said she might not."
Tatsuya adjusted the tourniquet placement. "Walking's the minimum. She'll probably need physical therapy for full range."
"Still. That's..." Taro set down his kit, choosing his words. "Yamamoto-sensei mentioned it. He doesn't mention things unless they matter."
"Focus up." Rika's voice cut through. "Rotations start in five. Save the mutual admiration for after."
The field went quiet. Tatsuya finished his preparations and let his eyes drift across the formations assembling below.

The exercise revealed what reports never could.
Tatsuya treated a hyperextended elbow, a genin who'd landed wrong on a combat roll, while watching the field.
The Uchiha moved first.
Their squad flowed across the eastern field with coordination that shouldn't have been possible with no verbal communication. Mikoto directed from center position. He'd seen her at Kushina's gatherings, relaxed and sharp-humored over sake. Here, Sharingan active, her posture shifts so subtle they looked like breathing, she was a different person entirely. The Uchiha around her responded before she finished signaling. Fugaku anchored the left flank, tracking three engagements at once. His hand signals looked like nervous tics unless you knew what you were watching.
They engaged an opposing team and it was over in seconds. Adjacent units moved to support; the Uchiha had repositioned. Their injured went to Uchiha medics. Their comms stayed on clan frequencies.
Impressive. The kind of coordination you couldn't build from scratch, only grow over generations of shared training, shared instinct. He watched Fugaku redirect an entire flank with two fingers and thought: this is what a real military unit looks like.
A genin arrived with a dislocated finger. Tatsuya reduced it and looked up in time to catch the Ino-Shika-Cho taking the field.
Shikaku, who'd cornered Tatsuya after a dinner weeks ago to pick apart the tactical applications of field medicine, now demonstrated why those questions hadn't been academic. His shadow stretched across the ground while Inoichi formed seals and Choza expanded. Eight seconds, four opponents neutralized. But where the Uchiha sealed themselves off, these three folded into regular forces afterward. Shikaku's shadow held targets while non-Nara chunin moved to capitalize. Inoichi coordinated units that had never trained with him.
The Hyuga deployed in formation, Byakugan active, gentle fist strikes ending engagements before they properly started. Hiashi directed from slightly behind the front line. The Aburame were subtler. Tatsuya didn't notice them at all until kikaichu beetles were sitting on his supply kit. He brushed them away carefully and made a note to watch for that in actual combat.
Between patients, sprains, contusions, a fractured rib, a badly landed shoulder, he scanned the field again.
Uchiha fans on flak jackets. Nara emblems. Akimichi kanji. Hyuga sleeves. Aburame presence felt more than seen.
No Senju crests.
The clan that had founded this village. That had produced the First Hokage, the Second, and arguably the strongest shinobi alive in Tsunade.
He'd picked up fragments over months. Jiraiya mentioning bloodline dilution once. An older medic at Section Seven going quiet when the name came up. Married into the general population, was one version. Bled out leading from the front, was another. He didn't have the full picture, and nobody seemed eager to fill it in.

The commotion started on the eastern field.
A red-haired figure was cutting through defensive formations with a brutality that caught him off guard. He'd sparred with Kushina, trained alongside her, eaten her cooking. But watching her fight at full intensity against opponents who weren't pulling punches was different. She moved like violence was a language she'd been forced to learn young, and she'd gotten fluent out of spite.
She wasn't using anything that looked like jinchuuriki power. Just speed, instinct, and the particular viciousness that came from years of proving herself against people who expected her to fail. Whatever the Fox gave her in terms of reserves, she wasn't drawing on it here. Didn't need to.
A chunin tried to flank her. She read it before he committed, pivoted, and put him down with an elbow to the solar plexus that Tatsuya felt in his own ribs from thirty meters away. The chunin folded. She was already moving.
From a medic's perspective, it was educational. She generated power from her hips and core, not her shoulders — textbook, but textbook at a speed that made technique look like instinct. Every strike landed where joints were weakest, where armor gaps left soft tissue exposed. She wasn't stronger than the people she was fighting. She was faster, meaner, and better at choosing where to hit.
Two chunin coordinated an approach from opposite angles. She let the first one commit, sidestepped, and used his momentum to put him between her and the second attacker. The second hesitated — just a fraction — and she closed the distance before he could reset.
Three Hyuga engaged her simultaneously. Byakugan active, gentle fist ready.
This was different. Gentle fist didn't care about armor gaps or soft tissue. It went straight for the chakra network, and the Byakugan meant no blind spots, no angles she could exploit. The smart move was to disengage and find different opponents.
Kushina grinned.
She dropped the first one before he finished his stance. The second took a palm strike to the sternum that sent him stumbling. The third blocked her initial attack, started to counter—
And found himself on the ground with no idea how.

Kushina arrived at station three twenty minutes later.
The bruise across her cheekbone was spectacular, purple shading toward green at the edges, and she was grinning like she'd just won a fight that mattered.
"Twelve." She dropped onto a supply crate. "Personal best."
"You're supposed to report injuries."
"I am reporting an injury. The injury is evidence I was actually fighting." She tilted her head, showing off the bruise like a trophy. "Three Hyuga. Three. Hiashi's cousin was one of them. His face when I—"
"Hold still."
She held. Mostly. Her fingers drummed against her thigh while he examined the bruise: impact trauma, no structural damage, would color impressively but heal clean.
"You could have avoided this."
"Where's the fun in that?"
He channeled healing chakra into the tissue, reducing the swelling. Her energy was infectious, hard to stay clinical when someone was radiating satisfaction like she was generating her own warmth.
"Meguri." Rika didn't look up from the suture kit she was re-threading. "You have three people waiting."
"Bruise. Non-critical."
"I can see that." Her tone said the rest: and yet here you are, chatting.
He finished faster after that.
"You'll still have a mark."
"Good." Her voice lost some of its manic edge. "Thanks for not telling me to be more careful."
"Would it matter?"
"No." The grin sharpened. "But everyone else says it anyway."
She hopped off the crate and headed back toward the field. Halfway there, she turned back.
