The uchiha’s grimoire guide to winning: interlude I: the sin known as hesitation

"Tell me Arashi, why are you hesitating?"

The question hung in the air of the dimly lit office, heavy and accusatory despite the elder's measured tone. Arashi didn't turn from the window where he stood, watching the compound below. From this height, he could see the training grounds where young Uchiha practiced their fire jutsu, the residential quarters where families gathered for evening meals, the memorial stone where names of the fallen were etched into black granite. All of it, every single person moving through those streets, every child laughing in those courtyards, every widow lighting incense at that memorial, all of it rested on his shoulders.

"Me, hesitating? What makes you think such, elder Tsurugi?"

The words came out lighter than he felt, almost casual, but Arashi knew better than to think he could fool a man who had seen two Hokage rise to power, who had fought in battles before Konoha even existed. Tsurugi had been there when Madara had walked away from the village, had been one of the voices arguing for reconciliation even as their greatest warrior abandoned everything they'd built. The old man knew hesitation when he saw it, could probably smell it like blood in the water.

"You saw what happened."

Four words. Just four simple words, but they carried the weight of everything that had transpired over the past hours, days, weeks. Everything that had shifted and changed and fundamentally altered the trajectory of the Uchiha clan.

Arashi sighed, finally turning from the window to face the elder properly. Tsurugi sat in one of the simple wooden chairs that furnished the clan head's office, his weathered face illuminated by the soft glow of the oil lamp on the desk. The man looked older than Arashi remembered, the lines around his eyes deeper, the gray in his hair more pronounced. Or perhaps it was just that recent events had aged them all.

"Yes, I did."

The admission felt like defeat somehow, like acknowledging a weakness he couldn't afford to have. But there was no point in denying it, not to Tsurugi, not to himself. He had seen it all, had witnessed every impossible moment.

He had told his nephew that only five Uchiha, amongst them his mother, his father, and his aunt, plus two Uchiha medics, were necessary to monitor his first activation of whatever abilities he had gained. It had been said with confidence, with the assurance of a clan head who knew what precautions were sufficient for testing a new bloodline ability.

The truth was that it was a lie, one they all knew without Ren. Not a malicious deception, but a necessary one, the kind of gentle fiction you told to keep a child from panicking, from understanding just how dangerous the situation truly was. Because Ren had almost died. Could even be argued to have died for some moments, his heart stopping, his breathing ceasing, his chakra network collapsing in on itself like a star going supernova. And when he had come back, clawing his way back to life, his Yin had been different. Heavier. Changed in ways that Arashi still didn't fully understand.

He had thought at first that it was because of his nephew's brush with death, the fact that he had awakened not only his Sharingan but his Sharingan with three tomoe. A complete maturation in a single moment, bypassing all the stages that normally took years of combat and loss and gradually accumulated trauma. It was unprecedented, shocking, the kind of thing that happened maybe once in a generation if that.

Things like that, changes like that, they changed your chakra naturally because your chakra, that fundamental mixture of physical energy and spiritual energy, couldn't not be affected by serious, important things happening to you. Death changed you. Coming back from death changed you even more. It rewrote something fundamental in your spiritual makeup, left scars that went deeper than flesh and bone.

Everyone's chakra had their own signature, a different color, a different texture, a different resonance when you felt it with sensory techniques. Your chakra was you, distilled into pure energy. It reflected your personality, your experiences, your traumas and triumphs, every significant moment that had shaped you into who you were. Sensor-nin could identify people by their chakra alone precisely because of this uniqueness, this fundamental impossibility of duplication.

Still, he hadn't expected that the change in Ren's Yin could have brought a mutation, a new bloodline limit. One that, like all things coming from Yin, could be said to be unnatural, different, new, foreign to what you should expect from normal human capability. Yin was deviation, after all. Yin was the power to make real what shouldn't be, to impose imagination onto reality, to break the rules that Yang enforced.

If Yang was life, the energy that animated and sustained the physical world, then Yin was death, or perhaps more accurately, the power to deny life's limitations. If Yin was what made the shape, the form, the concept of a thing, then Yang was what animated it, gave it substance and function and the ability to exist in the material world.

This was why people who used Genjutsu, who favored illusions, who were more cerebral and analytical in their approach to combat, were more inclined to Yin. They were imposing false realities onto the world, making people see and feel and experience things that didn't exist. That was pure Yin, the power of imagination and deception made manifest through spiritual energy.

This was why the strongest shinobi physically were the ones with a lot of Yang. Yang enhanced the body, made muscles stronger, bones harder, healing faster. It was additive, reinforcing what already existed and pushing it beyond normal human limitations.

It could be argued that, in other words, Yang ensured something worked the way it should, following the natural laws of the world, while Yin ensured something worked the way it could, bending or breaking those laws to achieve impossible results.

Yin was deviation from what should be the logical order of the world. Yang was advancement, an adding to something natural, an enhancement of existing capabilities rather than the creation of new ones.

This was why the Nara, with their Yin chakra, could control and manipulate shadows. Shadows weren't supposed to be solid, weren't supposed to be able to bind or strangle or move independently. But Yin made it possible, imposed that impossible reality onto the world and forced it to comply.

This was why the Yamanaka, with their Yin chakra, could read through your mind, see what you thought, access everything you had ever experienced, and warp all of it if they chose. Minds were supposed to be private, inviolable, but Yin said otherwise and made it true.

This was why the Akimichi could, with their Yang chakra, become bigger, stronger, transform into giants that towered over the battlefield. They were adding to the base they already were, strengthening the concept of their physical form, taking what already existed and multiplying it to extreme proportions.

But of all the clans in all the Elemental Nations with leanings toward Yang and Yin, it was the Senju with their Yang chakra, their Yang bodies that could sustain injuries and punishment that would kill normal shinobi, and the Uchiha with their Yin, with their Sharingan that imposed impossible perception and prediction onto reality, who did the most with their affinities.

Hashirama and Madara had been gods and demons in human shape. One who could create forests from nothing, whose Yang was so profound he could literally reshape landscapes. The other who could trap you in illusions so complete you couldn't distinguish them from reality, whose Yin was strong enough to control the most powerful of the tailed beasts.

Taking all of that into account, Ren's Yin mutation that allowed him to gain new abilities foreign to their understanding, abilities that he shouldn't have been able to possess while surprising, while extraordinarily rare, should not have been that shocking. Yin mutations happened. They were documented throughout shinobi history, new bloodline limits emerging when spiritual energy took unexpected forms.

This was what he had thought before the boy broke the greatest rule that the Uchiha clan, since its inception, had never been able to break.

The rule about unlocking the Mangekyō. The price to pay initially, blood and death of a loved one, the kind of trauma that shattered something fundamental in your psyche and rebuilt it into something harder and colder and infinitely more powerful. And the price to pay after, the progressive loss of sight the more one used the Mangekyō, darkness encroaching with every technique until you were blind, your greatest power rendered useless by its own cost.

Unless you switched eyes with another Mangekyō user, usually a close relative, creating what was called the Eternal Mangekyō Sharingan. But with how its activation was most of the time related to the demise of said relative, the murder or death of the person whose eyes you'd need to escape the blindness, and the way shinobi, especially Uchiha with their Sharingan, valued their eyesight above almost everything, that path was rarely walked. It required a level of sacrifice that most couldn't stomach, asking a loved one to give up their eyes, or worse, taking them from a corpse still warm from the kill that had awakened the Mangekyō in the first place.

The boy, his nephew, had unlocked an ability. A pink slime of all things he could summon and unsummon, manifesting it from nothing and dismissing it back into whatever space it occupied when not called. And he had said, had demonstrated with a certainty that brooked no argument, that this slime could not only heal but also, when ingested, make someone's chakra much stronger and bigger. And, most impossibly, unlock all the stages of the Sharingan without any drawback.

No trauma required. No death necessary. No progressive blindness. Just consumption of this substance and evolution, clean and simple and completely unprecedented in the entire history of the Uchiha clan.

The healing alone was proof enough that Ren was indeed the golden goose, the most valuable asset the Uchiha clan had possessed in generations, perhaps ever. Having him watched and protected by Uchiha specialized in stealth and protection details, shinobi whose entire purpose was to ensure nothing and no one could harm the boy, members beyond the five who were only supposed to be his minders and teachers, that was not just a good choice. It was the only choice, the bare minimum of what responsible leadership demanded.

Arashi had been there, even if in a way that ensured he would not be seen, his presence masked by both distance and the jutsu of the stealth specialists surrounding the testing ground. He had watched when the boy not only healed the bruises and little burns he had received from training with his aunt, injuries that should have taken days to fade vanishing in seconds under that pink substance. And he had been there when a retired elder who had once been a Jonin of significant skill, a man missing an arm lost in the wars before Konoha's founding, was discreetly brought forward so that the boy's healing could be properly tested.

The arm had literally regrown. Not regenerated slowly over weeks or months, but regrown in minutes, flesh and bone and muscle and skin forming from nothing, or perhaps from the pink slime itself, Arashi wasn't entirely sure. And when it was done, the elder looked as if too full of energy, moving like a man thirty years his junior, the chronic pain that had defined his retirement completely absent.

Just with that, all the Uchiha who were injured, who suffered from disabilities accumulated over years of service, who carried the physical costs of their sacrifice for the clan and village, could be healed. Now, each time one of them went into a mission and came back injured, came back with wounds that should be career-ending or life-altering, they could have the certainty that said family member would be healed even when it shouldn't be possible. Burns that should leave permanent scars, broken bones that should never set properly, damaged chakra networks that should end a shinobi's career, all of it could be fixed.

Of course, it should be done in a way that didn't attract the gaze of Tobirama, didn't draw the attention of the village leadership or the other clans until they were ready for that scrutiny. Sudden miraculous recoveries would raise questions they couldn't afford to answer, not yet. But still, the implications were staggering. The strategic advantage alone, the ability to maintain combat effectiveness even after injuries that would normally require months of recovery, was worth more than any number of jutsu scrolls or summoning contracts.

He had wondered immediately if this could be used to alleviate the problems that came with the Mangekyō. If it could heal the progressive damage, restore sight that had been lost to the eyes' own power. That alone would change everything.

In the clan, while all members with a mature Sharingan, the full three tomoe, who were older than thirty-five or who were proven worthy through service and accomplishment and thus permitted to know and read the Naka Shrine tablet with its secrets written in a script only their eyes could decipher, were aware of the Mangekyō's existence, there were no more than seven of them who actually possessed it. Seven users in the entire clan, and that was counting Arashi himself.

He had gained his years ago in the First Great Shinobi War, back when the villages were still finding their footing and conflicts erupted over borders that hadn't existed before the founding. His teammate had turned traitor, had led their squad into an ambush that killed three of their number and would have killed them all if Arashi hadn't done what was necessary. Putting a kunai through the throat of someone you'd trained with for years, someone you'd shared meals with and laughed with and trusted with your life, that did something to you. Changed something fundamental. And his eyes had evolved in that moment, the three tomoe bleeding into new patterns, new power, new cost.

He was the head of his clan, which meant that even without taking his eyes into account, he was strong enough to be worthy of the position. You didn't lead the Uchiha through politics alone, through clever words or family connections. You led because you were strong, because you could stand against any challenger and prove your right to command. But it didn't change that he had been losing his sight more and more since he had unlocked the Mangekyō, darkness encroaching from the edges of his vision, colors fading, details becoming harder to distinguish. Every time he used those eyes, every time he called upon their power in combat or crisis, he paid the price in increments of his vision.

If Ren's healing could put the degradation back to zero, could restore what had been lost and arrest what would continue to be lost, this would be a game-changer for the clan. For him personally. Because while the Mangekyō had heavy costs, costs that made you think twice before using it, costs that meant you saved it for only the most desperate moments, it still was powerful enough to eclipse said costs. The ability to cast genjutsu that even other Sharingan users struggled to break, to perceive time differently in combat, to access techniques unique to your eyes alone, that power was worth almost any price when your life or the lives of your comrades hung in the balance.

This was what he had thought before the boy showed the strengthening part of his ability. Before everything had shifted from "invaluable asset" to "fundamental threat to the balance of the shinobi world."

The boy had wanted to test it on himself, had volunteered with the kind of naive enthusiasm children had before the world taught them to be afraid. But the idea had been rightfully knocked down instantaneously by every adult present. The boy was too important to risk, too valuable to expose to unknown effects. What if it killed him? What if there were side effects they couldn't predict? No, testing on Ren himself was absolutely not acceptable.

The aunt of the boy, Fumiko, had made herself a volunteer instead. Had stepped forward with that reckless determination she'd always possessed, the same quality that made her brilliant in combat and terrifying in any situation requiring caution. And they had let her, partly because someone needed to test it and partly because if something went wrong, better a Jonin than the source of the ability itself.

The result of her eating part of the slime, consuming that pink substance that seemed to dissolve on contact with saliva, had been immediate and undeniable. Her chakra had exploded, surging from the respectable reserves of a skilled Jonin to something that rivaled, no, equaled what the founders of the village themselves, of Hashirama and Madara in their prime when he was young and had been lucky enough to interact with them. The sheer volume of it had been palpable even from Arashi's concealed position, washing over the training ground like a tsunami of spiritual energy, and he'd had to suppress his own Sharingan's instinctive activation in response to the threat.

But the chakra increase, as staggering as it was, hadn't been the most shocking part. What had stolen his breath, had made his heart skip beats in his chest, was what happened to her eyes.

The crimson of the Sharingan remained, but the pattern within was a spiral, elegant and hypnotic and completely unprecedented.

He knew just by looking that it was beyond his own Mangekyō. Knew it with the instinct of someone who had possessed advanced eyes for years, who understood power when he saw it. Whatever Fumiko had gained, it transcended the normal evolutionary path. It was something new, something different, something that existed outside the established rules.

And that was the reason why he was right now talking with and even entertaining elder Tsurugi's questions and concerns. Because what happened to Fumiko had proven that Ren's ability wasn't just limited to spying, healing and recovery. It was evolution, forced and artificial and apparently without limit. And that changed everything.

The logical thing, the rational choice that any clan head worth the title would make, would be to put Ren in a safe haven. A vault somewhere, protected by every seal and guard the Uchiha could muster, where nothing could ever hurt him, where no enemy could ever reach him, where he'd be completely secure from any possible threat.

He knew it was the logical thing, the choice that protected the clan's most valuable asset. Ren was too important, his abilities too precious, his potential too vast. Putting him in a cage, even if it was a golden cage with every comfort and luxury they could provide, was the thing he should do as the head of the Uchiha clan. The responsible thing. The strategic thing. The thing that ensured the boy's safety and the clan's future.

He knew this intellectually, could map out the reasoning, could articulate the arguments for why it was necessary. Yet he couldn't do it. Couldn't bring himself to give that order, to condemn a child to imprisonment no matter how gentle, to sacrifice a young life on the altar of clan security.

Because that boy was his nephew, was one of them. Was family in a way that transcended strategic value. And he didn't want to sacrifice the life, the happiness, the childhood of a boy who'd already been through too much, just for the greater good of the clan. Didn't want to become the kind of leader who saw people as tools, as assets to be protected and deployed and used up.

It would leave a bad taste in his mouth, he knew. One he would not be able to stomach, that would poison every decision afterward, that would turn him into something he'd sworn never to become. He'd seen what that path led to, had watched others grow cold and calculating and willing to sacrifice anything for power. He'd promised himself he'd be different, that he'd remember the people behind the Shogi pieces.

"I know." The words came out quieter than he intended, carrying all the weight of his internal conflict. "I know that I am hesitating, hesitating on a lot of things when as the clan head, I shouldn't. I am hesitating about how to deal with Konoha because no matter how much it tries to strangle us, no matter how many restrictions Tobirama places on our movements and our positions and our opportunities, it was born also of the will of our clan. Madara and Hashirama built it together, dreamed it into existence together, and we were part of that dream from the beginning."

He moved away from the window, pacing the small office like a caged animal. "I grew up believing in it, in this idea where children would not have to fight or be sacrificed or killed. Where they could play instead of training for war, where they could grow up with their families instead of dying before their voices deepened. That was the promise, wasn't it? That was what Konoha was supposed to be. And I still believe in that promise, even if the reality has fallen so far short."

Tsurugi watched him pace, silent, patient in the way only old men who'd seen everything could be patient.

"I am hesitating on how things should go forward," Arashi continued, his voice rising slightly with frustration. "If we should wait for long or not, wait until after the Second Great Shinobi War that we can all see coming, the one that will make the first one look small by comparison. If we should be bloody in our response to the village's treatment, show them we won't be pushed further, or if we should try negotiating, try reasoning with people who seem determined to see us as threats no matter what we do."

He stopped pacing, turned to face Tsurugi directly. "I hesitate a lot when I should not, when a clan head should be decisive and certain and willing to do whatever is necessary. But tell me, should I stop and do only the logical thing no matter how many it hurts? Should I stop hesitating, stop searching for other alternatives? Should I just lock Ren away and turn him into the clan's secret weapon, sacrifice his childhood and maybe his sanity for our security? Should I prepare for war with the village that was supposed to protect us? Should I make all the hard choices and stop caring about the costs?"

The questions hung in the air between them, desperate and genuine. Because Arashi truly didn't know. Didn't know if his hesitation was wisdom or weakness, if his desire to find another way was hope or delusion.

The elder sighed, a sound that carried decades of experience and loss. He shifted in his chair, and for a moment he looked every one of his many years. Then he stood, moving with the careful precision of someone whose body had been broken and healed too many times, and sat down on the cushioned seat beside Arashi's desk.

"To begin with," Tsurugi said, his tone shifting to something almost amused, "you should put more sake in this room. It would probably make things a lot easier in different ways. Difficult conversations go down smoother with good alcohol."

Despite everything, despite the weight of the decisions pressing down on him, Arashi felt a small smile tug at his lips. Leave it to Tsurugi to find humor in crisis.

But then the elder's expression softened, became serious again, and when he spoke his voice carried a gentleness that Arashi hadn't heard in years. "I can understand why you're hesitating. You're an Uchiha, it's in your nature to care. We feel everything more intensely than other clans, love and hatred and loyalty and grief. It's what makes our eyes what they are, that intensity of emotion. I wouldn't have pushed for you to be clan head so many years ago if you didn't care, if you were the type to sacrifice your people without a second thought."

Tsurugi leaned back, his weathered hands folding in his lap. "I can tell you only one thing, Arashi. Do what your heart tells you to do, no matter how harsh or foolish it may seem to others. In this world of war, death, and shinobi, the most important thing, what marks one as truly strong, is their heart. Their convictions. Their willingness to stand by their choices even when the whole world tells them they're wrong."

The old man's eyes, dark and knowing, held Arashi's gaze. "That's nothing but our way. The Uchiha way. We don't do things by halves, don't compromise our convictions for convenience. When we love, we love absolutely. When we fight, we fight until there's nothing left. When we believe in something, we hold to it even if it destroys us. That's what makes us strong, and it's also what makes us dangerous, to others and to ourselves."

Arashi felt something loosen in his chest, some knot of tension he hadn't realized was there. It wasn't permission exactly, but it was understanding.

"So you're saying I should trust myself," Arashi said slowly. "Even if it means going against what seems logical."

"I'm saying," Tsurugi corrected, "that logic is a tool, not a master. Use it to inform your decisions, but don't let it override what you know in your heart to be right. The purely logical choice is often the cruelest one, the one that treats people like numbers on a page. And while sometimes cruelty is necessary, it should never be your first choice. Never be something you do easily."

The elder stood, his joints creaking audibly. "Whatever you decide about the boy, about the clan, about Konoha, make sure it's a decision you can live with. Because you'll have to live with it for the rest of your life, and we Uchiha have long memories. We remember everything, our choices, our failures, our compromises. Our eyes don’t allow us to forget. Those things, they haunt us in ways other people can't understand."

Arashi nodded slowly, feeling the weight of those words settle into him. Tsurugi moved toward the door, but paused with his hand on the frame.

"And Arashi? For what it's worth, I think the boy is lucky to have you as his clan head. Lucky to have someone who sees him as a nephew first and an asset second. Don't lose that. Don't let this world take that from you. We've lost too many good men to the kind of thinking that treats people as tools."

Then he was gone, leaving Arashi alone with his thoughts and his decisions and the weight that was leading.
