Chapter 4

The silence that followed Kasumi's accidental display of Ice Release stretched taut between them, thick and cold as the frost she'd summoned. Ryuu sat rigidly at the low table, his small hands clenched in his lap, his mind racing. 

He didn't dare move, didn't dare speak, simply watched as Kasumi finished packing the fish with jerky, almost violent efficiency. Her usual grace was replaced by a brittle tension, her movements sharp, economical to the point of severity.

When she finally turned back to him, her dark violet eyes were shuttered, her face an impenetrable mask. There was no acknowledgment of what he'd seen, no explanation offered. She simply resumed their evening routine – preparing the meagre meal, checking the door latch, ensuring the paper screens were perfectly aligned. 

But the air in their small house had shifted irrevocably. The unspoken had been witnessed, and the fragile semblance of normalcy they maintained had cracked.

Ryuu understood the implicit command in her silence: We do not speak of this. It did not happen.

But it had happened. And it colored everything.

Kasumi's vigilance, already high, ratcheted up to an almost unbearable degree. Every creak of the floorboards outside, every unfamiliar voice carried on the wind, seemed to make her freeze, her head tilting, listening with an intensity that sent prickles of borrowed fear down Ryuu's spine. 

Her training sessions, disguised as games, became more frequent, more demanding. The focus shifted subtly from general survival skills to drills emphasizing absolute stillness, perfect concealment, and recognizing minute changes in the environment. She was honing his senses, sharpening his awareness, preparing him for flight or fight at a moment's notice.

He saw the strain it placed on her. 

Fine lines deepened around her eyes, and a permanent shadow of exhaustion seemed to settle beneath them. Sometimes, late at night, when she thought he was asleep, he would hear her pacing softly in the main room, the whisper of her feet on the wood a counterpoint to the rhythmic sigh of the nearby sea. 

His own efforts redoubled. The chakra control exercises Kasumi had begun teaching him took on a new urgency. He spent hours meditating as Kasumi instructed, chasing the elusive inner warmth, trying to coax it, command it, pull it towards his limbs.

It felt like trying to funnel mist with his bare hands. He could feel the potential, that faint current deep within, but directing it remained agonizingly difficult. His child's body, though recovering, lacked the developed chakra pathways, the sheer internal energy – the stamina, as Kasumi had simplified it – needed for easy manipulation. Progress was measured in fleeting sensations – a momentary warmth in his fingertips, a brief concentration of energy in his palm before it dissipated like smoke. Each small success was hard-won, leaving him feeling drained and shaky.

His body was far too young, so the progress was slow. If he had done this process just a year later the difference would have been massive, as the body developed, chakra manipulation and quantity increased.

Kasumi monitored his progress closely, offering quiet corrections on his posture, his breathing. "Patience, Ryuu," she'd murmur, seeing the frustration clouding his young face. 

He tried. He truly did. But patience felt like a luxury he couldn't afford. Every creaking floorboard, every distant shout, every unfamiliar boat sighted off the coast was a potential Kiri patrol, a potential discovery, a potential death sentence. The need to gain control, to unlock the power that might be his only shield, burned within him.

Life in Shiosai continued its harsh, unyielding rhythm. Ryuu accompanied Kasumi on her necessary errands, always under the shade of the umbrella, always wrapped against the elements and prying eyes. He saw the weariness deepen on the villagers' faces as supplies from the mainland remained delayed. 

He heard more hushed whispers about the masked Kiri boats demanding tolls, their demands growing bolder. Fear was a constant undercurrent, masked by gruff resilience.

One blustery afternoon, while Kasumi bartered herbs with Old Lady Misaki – the same woman Emi had quoted about red eyes meaning demons – Ryuu lingered near a group of fishermen repairing a large tear in a communal net. Their conversation was low, serious.

"...never seen the Mist act so openly before," one man, stout with a thick grey beard, muttered, his needle flashing expertly through the heavy twine. "Used to be sneakier. Now... it's like they don't care who sees them taking what they want."

"It's the Mist shinobi," another man spat, his voice tight with remembered fear or perhaps fresh anger. "Heard stories from my cousin in the capital... things are bad there. They are purging the cursed bloodlines..."

Ryuu's blood ran cold. Cursed blood. The euphemism was clear. Kekkei Genkai. The purges weren't just rumored, they were happening, escalating. While Yagura might not yet be the Mizukage, since he had heard that the third Mizukage was still in office, the situation was odd.

He knew that Madara had manipulated the events with Rin, resulting in her suicide, with Yagura becoming the next jinchuriki of Isobu, but he didn't know if the events had yet to happen.

There was a severe lack of information.

He felt a renewed urgency to push Kasumi towards leaving. He began subtly weaving his fears into their conversations, framing them with childish innocence.

"Kaa-san," he'd ask, using the intimate term for mother that felt both alien and strangely right on his tongue, "are the masked boats scary?"

Kasumi's hands would still momentarily in her task – mending clothes, preparing food. "They are just shinobi doing their job, Ryuu," she'd reply, her voice carefully neutral. "We have nothing to fear if we obey the laws and keep to ourselves."

"But... Old Man Takeda looked scared," Ryuu persisted, injecting a quiver into his voice. "And Emi said... she said people disappear."

Kasumi would pull him closer, her grip tight. "Shiosai is small, Ryuu. We are safe here. No one pays us any mind." But her eyes would betray her words, flicking towards the door, her jaw tightening almost imperceptibly.

He knew he was playing a dangerous game, poking at her deepest fears, but it felt necessary. He needed her fear directed outwards, focused on the encroaching threat from Kiri, rather than solely inwards on concealing their secret within the village. He needed her to see Shiosai not as a sanctuary, but as a trap waiting to be sprung.

———————————————————————————————————————

The accident happened during one particularly frustrating chakra control session. He sat cross-legged on the floor, sweat beading on his brow despite the cool air, his small fists clenched in concentration. He was trying to channel the flow down his arm, to pool it in his palm. 

After he was done with this, he could finally start the leaf concentration exercise, just like the naruto characters did. He pushed, mentally straining, focusing all his will, his desperation, his adult frustration at this childish body's limitations.

He felt a surge, stronger than before, a rush of that inner warmth – but it was cold, sharp, almost painful. It shot down his arm not as a gentle current, but as a jagged spike of energy. He gasped, his eyes flying open.

The air around his outstretched hand shimmered. The wooden floorboards directly beneath his palm suddenly bloomed white. Not frost this time, but a thin, brittle sheet of clear ice, maybe only an inch across, spreading outwards in delicate, crystalline patterns. It glittered unnaturally in the dim light of the room.

He stared, mesmerized and terrified. It was beautiful. It was impossible. It was Ice Release. His Ice Release.

The sound of a sharp, indrawn breath made him flinch. Kasumi stood frozen in the doorway to the main room, a basket of herbs dropped forgotten at her feet, its contents spilling across the floor. Her face was utterly devoid of colour, her eyes wide with a raw, visceral terror that went far beyond her usual caution. It was the look of someone staring death in the face.

In two swift, silent strides, she was across the room, kneeling before him. Her hands clamped down on his shoulders, her grip surprisingly strong, almost painful.

"Ryuu!" Her voice was a harsh, panicked whisper, shaking slightly. "What did you do?"

He couldn't speak, just stared at the ice patch, then up at her terrified face.

"Did anyone see?" she demanded, her eyes darting frantically towards the screen door, then back to him.

He shook his head mutely. They were alone.

Kasumi seemed to deflate slightly, but the terror remained etched onto her features. She reached out, her trembling fingers hovering over the ice patch. The moment her skin brushed against it, the ice dissolved rapidly, leaving behind only a dark, damp spot on the wood and a lingering, unnatural chill in the air.

She grabbed his small hand, turning it over, inspecting it minutely, then looked deep into his eyes, her own dark violet pools swirling with fear and something else… anguish?

"Listen to me, Ryuu," she said, her voice low, intense, each word laced with desperate urgency. "You must never do that again. Not ever. Not unless I am here, and I tell you it is absolutely necessary. Do you understand me? Never."

He nodded again, swallowing hard against the lump forming in his throat. The sheer force of her fear was more terrifying than the accidental manifestation of power.

"This…" she struggled for words, gesturing vaguely at the damp spot, "…this is why we hide. This is why we are careful. There are… people… who hunt those with abilities like this. They fear it. They hate it. They will kill for it, Ryuu. They will kill us."

Her voice broke slightly on the last word. She pulled him into a fierce, trembling hug, burying her face in his ridiculously white hair. He could feel the rapid beat of her heart against his small chest, the tension thrumming through her body.

He remained stiff in her embrace, his mind whirling. He hadn't needed the confirmation, but her raw terror hammered it home. The Yuki bloodline wasn't just a disadvantage, it was a death sentence in this land, at this time at least. Kasumi wasn't just cautious, she was living on a knife's edge, her every action dictated by the need to conceal the truth that could get them both brutally murdered.

When she finally pulled back, her composure was partially restored, the mask sliding back into place, though her eyes remained haunted. "We will continue your chakra training," she said, her voice regaining some of its usual firmness. "Control is paramount. Absolute control. You must learn to feel it, direct it, but never, ever let it manifest like that again. Not here. Not now."

He nodded solemnly, understanding the gravity of the command. This accidental slip had changed the stakes. Kasumi now knew he possessed the potential, the dangerous inheritance. Her training would become even more focused, perhaps even harsher, driven by her desperate need to ensure he could control it, conceal it.

But for Ryuu, the incident solidified something else entirely. He had the potential. Locked away, underdeveloped, dangerous – but there. Ice Release. A powerful Kekkei Genkai, one he knew could be honed into a formidable weapon, a tool for survival.

Kasumi saw it as a curse to be hidden. He, armed with knowledge she couldn't possibly possess, saw it as a key. A key to power, a key to changing their circumstances, a key to surviving not just Kiri patrols, but the apocalyptic future he knew was barreling towards this world.

He met Kasumi's worried gaze, offering the most reassuring expression his small face could muster. Inside, however, his resolve hardened like the very ice he had unintentionally created. 

He would learn control, yes. He would obey her warnings, for now. 

But he would not let fear be his cage. He would master this power, secretly if need be. And he would find a way to steer them away from this isolated coast, towards the turbulent heart of the world where knowledge and power resided. 

Towards Konoha. 

The path was fraught with danger, but staying here, waiting for discovery, was no longer an option. It was simply a slower form of suicide.
