Section Seven's patient ward was quiet. Late afternoon light filtered through reinforced windows, catching dust motes that drifted aimlessly. The usual sounds of medical emergencies, hurried footsteps and urgent commands, felt distant here, muffled by architecture designed to isolate.
Tatsuya reviewed the chart again. Hideki Tanaka. Jonin. Forty-two years old. Thirty years of active service.
The man sitting on the examination table didn't look broken. That was the cruelest part. He looked like any veteran shinobi in his forties: weathered face, steady hands, the kind of stillness that came from decades of conditioning. Only the slight tremor in his chakra signature, visible to anyone with decent sensing ability, betrayed the deterioration underneath.
"You're the one they've been talking about," Hideki said. His voice carried the resigned humor of someone who'd heard too many diagnoses. "The kid who thinks outside the manual."
"I'm not sure that's a compliment."
"Depends on who's saying it." Hideki flexed his fingers, watching them respond. "Yamamoto thinks you're either brilliant or dangerous. Tsunade-sama wouldn't have assigned you if she thought you'd waste my time." A pause. "So. What's the verdict?"
Tatsuya set down the chart. He'd spent the last hour examining the jonin's chakra pathways—what remained of them. Thirty years of high-level jutsu had left layered scarring throughout the network. The damage wasn't catastrophic yet, but it was progressive.
"I won't pretend I have better news than anyone else."
Hideki's expression didn't change. "Didn't expect you to. Let's hear it."
"Your pathways are degrading. Layered scarring from decades of chakra stress. Every A-rank technique you've used left traces, and the traces accumulated." Tatsuya met his eyes. "Current treatment protocols can slow the progression. Maybe. But they can't reverse it."
"Timeline?"
"Three to five years before you're at civilian capability. Maybe a bit longer if you reduce jutsu usage immediately. B-rank ceiling within eighteen months."
Hideki absorbed this with the stillness of a man who'd already known, who'd just needed to hear it said plainly. "That's about what the last three medics told me. Though they wrapped it in more hedging."
"I don't see the point in hedging."
"No." A flicker of approval crossed Hideki's eyes. "You don't." He rotated his wrist slowly, watching the movement as if seeing it for the first time. "Thirty years. Two wars. Hundred and forty-seven missions. And my body finally decides to quit on me during peacetime."
Tatsuya didn't respond. There was nothing to say that wouldn't sound hollow.
"The research you're doing," Hideki continued. "The cellular template work. Yamamoto mentioned it."
"It's... theoretical. Still. Probably years away from anything practical."
"Probably?"
"I don't know." The admission stung. "The foundation is sound: giving damaged tissue the information it needs to repair itself rather than forcing regeneration through raw chakra output. But turning theory into technique..." He trailed off. "I can't promise it'll work. Or that it'll work in time."
Hideki nodded slowly. "Honest. I appreciate that." He slid off the examination table, testing his balance, a habit, not a necessity. "Do me a favor, kid. Don't stop being honest when the brass starts wanting reassurances."
"I'll try."
"Good luck." Hideki moved toward the door, then paused. "Three to five years. That's more than some people get." A ghost of a smile. "Plenty of time to figure out what comes next."
He left. Tatsuya picked up his pen and started the intake report. Standard template. Progressive pathway degradation, layered scarring, palliative protocols recommended. The clinical language kept it manageable.

The door opened behind him before he finished writing.
Tsunade. He'd felt her chakra signature hovering nearby throughout the examination, observing without interfering. Now she stood in the doorway, arms crossed, expression unreadable.
"Assessment."
Tatsuya set down his pen. "Layered scarring throughout the primary pathway network. Damage is progressive, not acute. Current treatment protocols are palliative at best."
"Solution?"
"I don't have one."
Tsunade's eyes narrowed—not in anger, but in cold evaluation. "The cellular template research."
"Years away. Maybe longer. The theoretical framework is sound, but practical application requires—"
"I know what it requires." She stepped into the room, letting the door close behind her. "Kato spent fifteen years on that research. Died before he could finish it. I spent two years after his death trying to continue the work." A pause. "I failed."
"The approach was wrong," she continued. "His and mine. We were trying to preserve templates from healthy tissue—snapshots of what the body should look like. But healthy tissue degrades. The templates corrupt. By the time you need them, they're useless."
"So the information has to come from somewhere else."
"Somewhere, or something." She crossed to the window, looking out at nothing in particular. "Fourteen veterans currently on the active roster have damage similar to Hideki's. Some worse. I examined every one of them. Tried every approach I knew."
"And?"
"And they're all still dying by degrees." The words were flat, matter-of-fact. "I don't have a solution either. I've tried every approach I know." Her jaw tightened. "Sometimes that's the problem. I've been inside this research for six years. I know every dead end. Every failure mode. Hard to see past them."
"Why me?"
"Because you haven't failed at it yet." Tsunade turned from the window. "I look at Kato's notes and I see what went wrong. You look at them and see what might still work. That's not talent—that's just not carrying the same baggage."
"That's not—"
"I'm not asking you to fix everything." Her voice cut through his protest. "I'm asking you to do what I couldn't. Take the time. Find an approach that actually works." Her gaze held his. "Can you do that?"
The honest answer was that he didn't know. The research was promising but speculative. Years of work, possibly decades, with no guarantee of success.
But the honest answer wasn't what she was asking for.
"We'll see."
"'We'll see' isn't enough." No softening in her voice. "Results or nothing, Meguri. That's how medicine works. All the theory in the world doesn't matter if you can't save the patient."
She walked to the door, pausing with her hand on the frame.
"Hideki served with my team during the last war. Pulled me out of a bad situation once." A beat. "Don't let him be the benchmark for what's possible."
She left. Tatsuya stood alone in Section Seven, surrounded by charts and research notes and the weight of fourteen people whose bodies were slowly failing.
Tomorrow's problem, his mind suggested.
He filed the thought away. Some problems didn't wait for tomorrow.

Orochimaru's laboratory was exactly what Tatsuya had expected and nothing like what he'd feared.
The space was clinical and clean, every surface organized with the precision of someone who viewed chaos as a personal insult. Preserved specimens lined the walls in sealed containers, each one labeled, documented, dated. A reference library of biological curiosities.
"You seem surprised." Orochimaru's voice carried faint amusement.
"I expected something more..." Tatsuya searched for the word. "Dramatic."
"Ah. The rumors." Orochimaru moved between workstations with the fluid grace of someone entirely comfortable in his domain. "I find that reputation often precedes reality. People expect the snake den. They receive the research archive."
He gestured toward a wall of preserved specimens. "Everything here is documented and authorized. Research donations, battlefield recovery, approved experimental protocols. The oversight committee reviews my acquisition records quarterly."
Tatsuya examined the nearest container. A preserved chakra pathway network, suspended in some kind of preservation medium that maintained the tissue's integrity at a cellular level. The work required to extract this intact was remarkable.
"Impressive technique."
"Mm." Orochimaru appeared beside him. "That particular specimen came from a retired jonin. Terminal illness, no surviving family, wished to contribute to medical advancement." A pause. "The documentation is available if you'd like to verify."
