Finn sat with his tea and said nothing for a moment.
His brows had drawn together slightly — not deeply, not in a way that looked like alarm, just the minor furrow of a man turning something over. Black Zetsu watched it and did not allow himself to feel encouraged yet. Men who were genuinely unsettled showed more than that.
"Interesting," Finn said at last. He took a sip. "So after all of that, the conclusion is: give back the Rinnegan."
Black Zetsu paused, then gave a small nod. "For the purposes of what I described — the resurrection, the subsequent steps — the Rinnegan is a necessary component, yes."
"Mm." Finn set the cup down. His expression shifted — not quite a sneer, but something in that direction. "If you genuinely believed a few sentences would convince me to hand that over, you overestimated your own persuasiveness considerably."
Black Zetsu did not argue the point. He let a beat pass, then slid a scroll from his sleeve and held it out with both hands.
"We didn't come expecting something for nothing," he said. "We brought a gift."
Finn looked at the scroll without taking it yet. "Tell me what it is."
"You have Sharingan in your possession — we're aware that Orochimaru brought them from Konoha. Having the eyes is one thing. Understanding what's actually inside them is another matter entirely." Black Zetsu kept his tone even and informational, the register of someone offering a practical exchange rather than a bribe. "This scroll contains a complete record of the Sharingan's deeper techniques — the specific eye abilities, their mechanisms, the conditions for their use. Madara-sama's personal understanding of them, compiled in full. As the Uchiha clan's former pinnacle, his knowledge of the Sharingan was unmatched."
Finn reached out and took the scroll.
He held it without opening it, feeling its weight. His expression remained composed, but something behind his eyes had shifted from the quality of polite attention to the quality of genuine calculation.
This is precisely what I needed and didn't have a clean path to get.
The Sharingan techniques — Izanagi in particular — were Uchiha clan secrets. Not ninjutsu you found in a general library, not techniques that leaked into the wider world through ordinary channels. Danzo had them, probably, and Finn had been vaguely considering how to arrange that conversation. Failing that, the night of the Uchiha massacre would eventually produce opportunities, but that was years away and contingent on events he had no intention of accelerating.
And now Black Zetsu had walked in and handed him the complete documentation.
Izanagi was, at its core, a mechanism for treating a moment of death or defeat as if it had never occurred — rewriting a single catastrophic outcome back into the realm of possibility. As a contingency, it was almost absurdly valuable. No one knew when something fatal would arrive unexpectedly. Having a way to un-happen a killing blow, even once, was the kind of backup that changed the arithmetic of survival in ways that were difficult to overstate.
Beyond that, the detailed understanding of the Sharingan's full capability range would accelerate Orochimaru's research substantially. In the original arc, Orochimaru had spent years working from incomplete material — feeling his way forward without a map, relying on whatever Danzo made available and whatever he could deduce independently. This scroll changed that entirely.
"The gift is appropriate," Finn said. He set the scroll on the table beside the sword rack. "I won't be returning the Rinnegan. Not at present."
"I understand," Black Zetsu said, and he did. The first contact was never the close. The first contact was the opening.
"However," Finn continued, and his tone shifted slightly — not warmer, but more focused, the way a man sounds when something has genuinely caught his attention. "The stronger and higher-level power you described. You mentioned Nagato would have been able to resurrect Uchiha Madara at the right moment. When exactly is that moment?"
There it is. Black Zetsu felt the shift and was careful not to let his satisfaction show. The bait was in the water.
"It depends on specific conditions being met, Lord Finn. You captured what you likely know as the Outer Path Demon Statue during the Rain Country operation."
Finn raised an eyebrow. "The Gedo Mazo."
"Yes. That statue was constructed specifically by Madara-sama as a container — a vessel built to receive and hold the chakra of the tailed beasts." Black Zetsu paused here, omitting cleanly. No mention of the Ten-Tails. No mention of the Divine Tree. The simplified version was the only version Finn needed for now.
"The right moment comes when all nine tailed beasts have been collected and sealed within that statue. At that point, a person possessing the Rinnegan activates the seal, and Madara-sama returns. With the combined chakra of all nine beasts at his disposal, he would then possess the means to unlock a level of power that hasn't existed in this world since the Sage of Six Paths himself."
Finn nodded slowly, following the logic. "The power of nine tailed beasts combined. And that unlocks what, specifically?"
"The path to Six Paths power," Black Zetsu said. "The Outer Path Demon Statue, fully activated by that combined chakra, becomes something entirely different from what it currently is. Anyone sealed within it as a Jinchūriki at that moment would stand at the threshold of the Sage's realm."
"Interesting," Finn said, in the tone of a man who genuinely finds something interesting. His eyes were calm. "So there is a prerequisite."
"One condition," Black Zetsu said. "The process requires the Sharingan — or more precisely, the bloodline of the Uchiha clan. It cannot be bypassed."
The temperature of Finn's attention changed. Not dramatically, but the quality of his focus sharpened, and with it came something at the edges that was not quite warmth.
"Why," he said flatly.
"The Uchiha clan descends from the Sage of Six Paths' lineage. The bloodline carries a specific resonance with the power in question. Without that key, the door cannot be opened. The records are clear on this point."
He can't verify it, Black Zetsu noted internally. And anything he reaches for to verify it will only confirm what I've told him, because I've built it around things that are fundamentally true.
Finn was looking at him with an expression that contained a flicker of something cold — not anger exactly, but the careful assessment a man makes when he is deciding whether the person in front of him remains useful.
"Don't be concerned," Black Zetsu said, before that assessment could crystallize. "Once Madara-sama is resurrected and reaches the level of the Six Paths Sage, he would possess the authority to dissolve that bloodline barrier entirely. He could grant the same access to others. To you, specifically, if you were party to making it happen."
Finn stared at him.
Then he laughed.
It wasn't performed. It came from somewhere more genuine — short, slightly sharp, the sound of someone who has heard a sufficiently audacious thing and found, despite themselves, that they respect it.
"So the arrangement is: I help resurrect Uchiha Madara, he achieves godhood, and then — out of the goodness of his heart — he lifts me to the same level." Finn let the laughter finish. His eyes settled on Black Zetsu with an expression of clear, open amusement. "You're asking me to trust that Uchiha Madara, after reaching the apex of power, would willingly share it with someone else. You understand how that sounds."
"I understand how it sounds," Black Zetsu said.
"Then explain to me why I should believe it."
"Because he is Uchiha Madara."
Finn blinked.
He looked at Black Zetsu for a moment with something that might have been genuine surprise — not at the content of the answer, but at its simplicity. The complete absence of elaboration. Four words delivered with the calm certainty of someone stating a fact about the nature of the tide.
Several seconds of silence.
Then the laugh came back, longer this time, and fuller. It filled the room and tapered slowly down into something quieter and more considering.
"You're right," Finn said. He nodded once, and it looked like genuine appreciation. "That's actually correct."
Everything Black Zetsu had described was almost certainly fabricated. The precise mechanism, the tailed beast collection sequence, the bloodline prerequisite, the path to Six Paths power — all of it constructed carefully around a core of real lore, engineered to lead Finn toward conclusions that served someone else's project entirely. He knew this with near certainty.
But the final claim — that Madara, upon reaching such a level, would keep his word rather than eliminate a potential rival — that one happened to be true.
Uchiha Madara was many things. He had manipulated Obito with sustained and calculated cruelty, had arranged events across decades like a man moving pieces across a board he'd designed himself, had done things that a simpler moral vocabulary would call unforgivable. But at the foundation of his character there was something that remained genuinely inflexible: he would not stoop. He would not break a promise because he was afraid of what someone else might become. The pride that made him dangerous was the same pride that made that particular betrayal impossible. He would rather be matched by an equal he had created than survive as the man who had cheated to prevent one.
If this were real, and if Madara had made such an agreement, he would keep it. Not because he was good. Because he was Madara.
"Interesting," Finn said, setting the word down with care. "I'm not agreeing to anything. This needs consideration — it's not a small matter." He waved one hand toward the door. "You can go."
Black Zetsu appeared to have more to say. He looked at Finn's face and decided to leave it for another visit. A small incline of the head, and he moved toward the door, White Zetsu following close behind.
The door closed.
Finn remained at the tea table. He picked up the scroll Black Zetsu had left and turned it over once in his hands, then set it back down.
Two actors had performed for each other in a closed room, each fully aware the other was performing, neither one willing to break character first.
He picked up his cup. The tea had gone slightly cool.
Not bad, he thought. Not bad at all.
