The eyes were wrong.
Kagetsu had catalogued every larval variant this colony had produced across four separate mutation lines, and none of them — not the armored ones, not the fast ones, not even the failures — had eyes that tracked.
This one tracked him.
---
He didn't move.
Behind him, Minato had gone very still, kunai already loose in his hand from a habit that hadn't faded since the desert.
"Kagetsu." His voice was low. Controlled. "Step back from the dish."
"Give me a second."
"That wasn't a request."
Kagetsu didn't step back. He leaned in, close enough to fog the glass, and watched the sixth larva's pupil — if it was a pupil, if that word even applied — contract in response to his shadow falling across it.
Light reactive, he thought. Not just alive. Aware.

[Talent Card: Divergent Expression]
World: Bleach
Quality: Rare
Effect (updated): One divergent branch has stabilized into a Dormancy-class specimen exhibiting delayed neural onset — cognitive activity beginning hours after morphological completion, rather than concurrent with it.
The bracket text blinked into existence at the edge of his vision, and Kagetsu felt something settle in his chest that was half relief and half a colder feeling he didn't have a name for yet.
It's not malfunctioning, he thought. It's on a different clock.
---
"Kagetsu." Minato's voice hadn't relaxed. "What does that mean. In words I can use."
"It means the sixth larva didn't glitch." Kagetsu straightened, finally, giving Minato the reaction he wanted. "It means its brain finished building itself three hours after the rest of its body did. Like — imagine being born already grown, and then waiting three hours for the lights to turn on inside your own head."
"That's not comforting."
"It wasn't supposed to be comforting. It was supposed to be true."
---
The larva pressed itself against the glass.
Not aggressively. Curiously — the same way a child might press a palm to an aquarium, testing whether the world on the other side was real or only pictured.
Kagetsu felt the hair on his arms rise anyway.
"The others didn't do this," he said, quieter now, more to himself than to Minato. "The armored ones react to threat. The fast ones react to stimulus. This one is reacting to me specifically. It's oriented toward the observer."
"Meaning?"
"Meaning I don't think it's looking at a shape in front of the glass." Kagetsu didn't look away from the dish. "I think it's looking at the first thing it saw when its head turned on. And I was standing here when that happened."
---
Minato's kunai hand had not relaxed one degree since the larva moved.
"You're saying it imprinted."
"I'm saying I don't have a better word for it yet." Kagetsu tapped the glass once, gently, and the larva's whole body turned to follow the sound, quick and eager in a way that made his stomach twist somewhere between fascination and something closer to guilt. "Give me time and I'll have a better word."
"You don't get unlimited time." Minato's voice sharpened, some of the desert still audible underneath it. "That's the whole reason I'm standing in this lab. Someone dangerous has taken an interest in what you build here, Kagetsu. I need you treating every single thing in this room like it might be evidence in a case you don't know you're on trial for."
Kagetsu finally turned to look at him fully.
"You still haven't told me who."
"I can't."
"Can't, or won't."
"Both," Minato said, and for the first time there was something almost apologetic underneath the urgency. "It's not my call to make. I know how that sounds coming from the man who just told you to be careful without telling you why. I know it's not fair."
"Fair's not really the metric I'm working with," Kagetsu said. "Useful is the metric I'm working with. And right now you're giving me a warning with the details filed off, which is the least useful shape a warning can take."
---
Minato exhaled, long and slow, and for a moment looked less like the Fourth Hokage and more like a man who hadn't slept in two days, because he hadn't.
"I fought someone in the desert," he said finally. "Someone I couldn't touch. Someone who read one of my own techniques before I'd finished forming the hand seals for it — not guessed. Read. Like the jutsu existed for him a half-second before it existed for me."
Kagetsu went quiet.
"That's not a shinobi ability," he said slowly. "That's a data problem. That's someone operating with access to information that shouldn't exist yet."
"I know."
"And this person knows my name."
Minato didn't answer that. He didn't have to. The silence did the answering for him, and it was the loudest thing in the room.
---
The larva pressed harder against the glass.
Kagetsu looked back down at it — this small, wrong, curious thing that had opened its eyes and immediately, instinctively, chosen him as the first fixed point in an otherwise unmapped world — and felt the shape of a decision starting to form somewhere he couldn't quite articulate yet.
"I need to accelerate the colony program," he said.
"That is the opposite of careful."
"No." Kagetsu shook his head, already turning toward his workbench, already reaching for a fresh sample tray. "If someone with information from outside normal time is deciding whether I'm an asset or a liability, then the only leverage I have is making the asset side of that equation heavier than the liability side. I can't out-fight whatever you fought in that desert. I can build something that makes killing me a worse trade than not."
Minato's jaw tightened.
"That's not the plan Hiruzen and Orochimaru discussed."
"Then it's a good thing," Kagetsu said, not unkindly, already pulling on a fresh pair of gloves, "that I wasn't in the room when they discussed it."
---
Behind him, in its dish, the sixth larva let out a sound.
It wasn't a chirp. It wasn't a hiss. It was something in between, something that hadn't existed in any of Kagetsu's recordings of the colony before this exact moment — a low, rhythmic pulse of noise that repeated three times, paused, and repeated three times again.
Kagetsu turned back slowly.
"That's not a distress call," he said. "That's a pattern."
He reached for a notebook with a hand that wasn't quite steady.
"It's trying to say something."
And on the fourth repetition, the pulse changed.
It stopped sounding like the larva at all — and started, unmistakably, impossibly, sounding like a fragment of human speech.
