Two days after asking Gifted for this teaching, Kelvin Stone woke up before the sun.
He hadn't slept—not really. His body lay still for hours, but his mind raced through forests of flame and lightning, through hospital corridors that smelled of antiseptic and failure. When gray light finally seeped through his window, he was already dressed in his training gear, sitting on the edge of his bed, staring at his hands.
Weak.
The word tasted like copper.
He closed his fingers into fists, feeling the knuckles crack. Then he stood and walked to his brother's room.
Cavil Stone answered the door looking like he'd been awake for days himself—hair matted, eyes red-rimmed, the academy uniform he'd fallen asleep in wrinkled beyond salvation. At seventeen, he was lean where their father was broad, sharp where Thomas was steady. The balaclava mask from that night patrol was stuffed in his back pocket, visible enough to remind Kelvin that his brother, too, carried secrets.
"You look terrible," Cavil said.
"I need you to train me."
The words came out flat. No pleading. No explanation. Kelvin had spent the night rehearsing arguments, preparing to beg, to bargain, to barter his pride for knowledge. But looking at his brother's exhausted face—mirroring his own—he found he had no energy for performance.
Cavil studied him for a long moment. Then he stepped aside, letting Kelvin into the room that smelled of sweat and steel polish.
"Close the door."
Kelvin did.
"Mom know you're here?"
"No."
"Good." Cavil moved to his desk, picking up a half-empty canteen and draining it. "Because she'd try to stop this. She thinks you're still—" He caught himself, shaking his head. "She thinks you need protection."
"I need to get stronger."
"For what? The academy? Rankings?" Cavil's voice sharpened. "Or because you think you can help Dad?"
Kelvin flinched. "I heard what that man said. In the forest. About me changing everything."
Cavil's hand froze halfway to setting down the canteen.
"You were listening."
"I was there. When they brought him in. I heard—"
"Kel." Cavil turned, and for the first time, Kelvin saw real fear in his brother's eyes. Not concern. Not worry. Fear. "That man had a Sharingan. Do you understand what that means? He could have killed Dad without trying. He chose to talk instead. People like that don't warn you unless they want something."
"Then I need to be strong enough that it doesn't matter what they want."
Silence stretched between them, thick enough to choke on.
Finally, Cavil exhaled through his nose, a sharp sound like a blade leaving its sheath. He walked to his closet, pulled out a second training outfit—black, simple, worn at the knees—and tossed it at Kelvin's chest.
"Change. Meet me in the backyard in five minutes."
"You're going to—"
"I said five minutes." Cavil was already unbuttoning his wrinkled uniform, not looking at him. "And Kel? I don't care if you're my brother, if you're younger, if you just watched Dad almost die. I'm not going to coddle you. You want training? You'll get training. But you'll hate me for it."
Kelvin caught the outfit, feeling the fabric's rough weight.
"That's fair," he said.
The backyard wasn't large—a narrow strip of earth between the Stone house and the neighbor's fence, barely twenty meters of packed dirt and stubborn grass. Thomas had installed training posts years ago, wooden pillars now gray and splintered from weather and impact. A single lantern hung from the eave, unlit in the dawn dimness.
Cavil was already there when Kelvin emerged, dressed in black, doing stretches that looked more like combat forms than warm-ups. He didn't pause when Kelvin approached.
"Your stance is wrong," he said immediately.
Kelvin looked down at his feet, positioned the way his father had taught him—shoulder-width apart, weight balanced, hands loose at his sides.
"Too defensive," Cavil said, finally turning. "You're preparing to receive an attack. Not to create one." He moved suddenly, a blur of black cloth, and Kelvin found himself on his back before he could react, dirt in his mouth, Cavil's knee pressing into his sternum.
"Again," Cavil said, rising smoothly. "This time, expect me."
Kelvin scrambled up, adjusting his stance, trying to find aggression in his posture. Cavil circled him like a shark, and Kelvin forced himself not to track the movement, to keep his eyes forward, to—
Cavil struck from the left, a palm aimed at his ribs. Kelvin blocked—barely, awkwardly—and tried to counter with a knee that hit nothing but air. Cavil had already vanished, reappearing behind him, and a chop to the back of Kelvin's neck sent him sprawling.
"You're thinking," Cavil said, not even breathing hard. "Gifted told you to stop thinking, didn't he? During your little playground sessions?"
Kelvin pushed himself up, jaw tight. "He said to flow. Like jazz."
"Gifted is an idiot savant who can't read a textbook but can kill a man twelve different ways with a spoon." Cavil resumed his circling. "But he's not wrong. Thinking is slow. Knowing is fast. You need to train until your body knows what your brain is still figuring out."
They trained for two hours before the sun cleared the horizon. Two hours of being knocked down, corrected, knocked down again. Cavil showed him three D-rank jutsu—basic techniques academy students weren't meant to learn until their second year.
"Substitution Jutsu," Cavil demonstrated, vanishing in a puff of smoke and reappearing on the fence. "Requires timing, not chakra. You replace yourself with an object at the exact moment of impact. Too early, they see the switch. Too late—" He dropped back down, landing silently. "—you're hit."
"Transformation Jutsu," he continued, his features blurring, shifting, becoming a perfect replica of their mother for three seconds before snapping back. "Maintaining the illusion drains chakra constantly. Most academy kids use it for pranks. You'll use it to survive."
"And this—" Cavil formed hand seals faster than Kelvin could follow, ending with his palms pressed together. "—is the Clone Jutsu. Not shadow clones. Not water clones. Just basic chakra constructs. Distract, confuse, buy time."
A pale, translucent version of Cavil stepped out from behind him, moving stiffly, clearly artificial. It dissolved after ten seconds, chakra dissipating like morning fog.
"You're not ready for that one yet," Cavil admitted. "Your reserves are too small. But Substitution and Transformation—you can manage those. Practice them until you can do the seals blindfolded."
When their mother called them for breakfast, Kelvin's body felt like ground meat. Every step sent fresh pain through muscles he hadn't known existed. Cavil walked beside him, barely sweating, and said nothing until they reached the door.
"After school," he murmured, too quiet for their mother to hear. "Same place. Don't tell Dad."
Kelvin nodded. It was the first time he'd felt like he was doing something instead of just waiting for the world to hurt him again.
The academy day passed in a blur of exhaustion.
Kelvin sat through lectures on chakra theory, barely keeping his eyes open. When the instructor called on him to explain the relationship between nature transformation and elemental affinity, he answered correctly by reflex—Cavil had drilled him on it that morning, between throws and takedowns.
Gifted noticed. Of course he did.
"You're different today," Gifted said during the lunch break, sliding onto the bench beside Kelvin with his usual grace. "Slower. But also... sharper? Like a knife that's been used too much but hasn't broken yet."
"Poetic," Kelvin muttered around his rice.
"Accurate." Gifted studied him with unsettling intensity. "You're training with someone else. I can tell. Your blocks changed. More efficient. Less... Gifted-influenced."
Kelvin considered lying. Considered deflecting. Then he remembered Cavil's words: Thinking is slow.
"My brother," he said. "Older. Final year. He's teaching me D-rank jutsu."
Gifted's eyebrows rose. "Illegally?"
"Technically."
"Beautiful." Gifted grinned, sharp and genuine. "I knew you had larceny in your soul. Rank Ninety-Seven, breaking rules, lying to authority figures—"
"I'm not lying."
"Omitting is lying's elegant cousin." Gifted stood, stretching arms overhead. "Fine. Keep your secrets. But if you're getting private lessons, I expect improvement. Tomorrow, we spar. No holding back."
"Tomorrow I might be dead from today's training."
"Then I'll fight your corpse. More challenging than most live opponents." Gifted walked away, whistling something off-key, leaving Kelvin to wonder if that was affection or threat.
Evening brought the second training session.
Cavil was merciless in ways Gifted never was. Where Gifted flowed around attacks, Cavil crashed through them, teaching Kelvin that sometimes the best defense was making your opponent afraid to attack. They practiced Substitution until Kelvin's hands cramped from the seal formations. They drilled Transformation until he could hold his mother's appearance for thirty seconds before the chakra drain made his vision swim.
When they finally stopped, stars had replaced the sun, and Kelvin's clothes were soaked through with sweat and dirt.
"Again tomorrow," Cavil said, tossing him a towel. "School, then me, then sleep. No exceptions."
Kelvin caught the towel, too tired to nod.
"And Kel?" Cavil's voice softened—just slightly, just enough. "Visit Dad. He asks about you. But don't—" He paused, choosing words. "—don't tell him about this. He'd blame himself. For not being there. For making you feel like you had to... compensate."
"I know," Kelvin said quietly.
He did visit. Every night, without fail, he sat by his father's hospital bed and talked about academy gossip, about Gifted's latest idiocy, about the theory test he'd barely passed. He described the weather, the food, the way the training grounds looked at sunset. He omitted the bruises, the blood in his spit, the way his hands shook when he tried to hold a pencil after too many hours of seal practice.
Thomas listened, half-conscious most days, painkillers dragging him under. But his eyes—when they opened, when they found Kelvin—held something fierce and grateful.
"Growing up," Thomas whispered once, voice rough as gravel. "Too fast."
"Someone has to," Kelvin replied, and his father closed his eyes, unable to argue.
His mother found out on the third day.
Not because Kelvin told her. Because she woke before dawn, unable to sleep, and saw the backyard lantern burning while her sons moved through kata like mirror shadows. She didn't interrupt. She watched until they finished, until Cavil walked Kelvin through the Transformation Jutsu one more time, until Kelvin collapsed against the fence post and laughed—actually laughed—at some joke Cavil made about his footwork.
Then she brought them water. And supplements. Small pills in a amber bottle, unlabeled, that she pressed into Kelvin's palm with trembling fingers.
"For recovery," she said, not looking at Cavil. "Your father used them during the war. They boost chakra circulation, speed healing, keep the mind sharp when the body wants to quit." She finally met Kelvin's eyes, and he saw the fear there, the same fear he'd seen in Cavil's. "But they don't make you invincible. Push too hard, take too many, and your body will break. Not gradually. Catastrophically. Your chakra pathways will scar. Your potential will burn out before it ever ignites."
"I understand," Kelvin said.
"Do you?" She caught his wrist, grip surprisingly strong. "Your father is a veteran of three wars, and he still wakes up screaming. Your brother was twelve when he killed his first man—twelve, Kelvin—and he still flinches at sudden noises. This path you're walking... it doesn't lead to glory. It leads to survival, if you're lucky. And if you're not—"
"I understand," Kelvin repeated, softer now. He covered her hand with his own. "But I have to walk it anyway."
She released him. Turned away. But she left the supplements on the fence post, and she didn't forbid the training.
That was permission enough.
One week later, Kelvin Stone was no longer Rank Ninety-Seven.
He hadn't climbed to Gifted's forty-nine—that would require official tournament results, practical demonstrations, instructor evaluations. But in the private ledger of his own improvement, he had become something else. Someone who could form hand seals in his sleep. Someone who could Substitution-jutsu out of a surprise attack nine times out of ten. Someone whose body no longer trembled after Cavil's training, but hummed, ready, waiting.
Gifted noticed.
They stood in the training grounds as the sun bled gold across the horizon, long shadows stretching into infinity. Other students had left for home. The evening air smelled of cut grass and distant cooking fires.
"Rules," Gifted said, rolling his shoulders loose. "No surrender. No yielding. No 'I give up' or 'that's enough.' We fight until one of us cannot stand. Unconsciousness is the only victory condition."
"That's insane," Kelvin said, but he was already loosening his stance, finding that aggressive edge Cavil had taught him.
"That's honest." Gifted smiled, fierce and bright. "All our other spars, we've held back. Worried about injury, about rules, about tomorrow's classes. Tonight?" He raised his hands, chakra already flickering at his fingertips. "Tonight we find out who we really are when nothing matters but the next breath."
Cavil appeared from the tree line, silent as smoke, taking position at the field's edge. He said nothing, gave no signal, but his presence was permission and judgment both.
Kelvin and Gifted circled each other, and the world narrowed to a single point.
Gifted struck first.
Not with a punch—with a feint, a subtle shift of weight that drew Kelvin's guard left before Gifted's real attack came from the right, a palm strike aimed at Kelvin's temple. Kelvin barely Substitution-jutsued in time, leaving a log to take the impact while he reappeared three meters back, heart hammering.
"Already?" Gifted laughed, destroying the log with a follow-up kick. "Cavil's been generous!"
Kelvin didn't answer. He was moving, using the Transformation Jutsu mid-stride—becoming Cavil, becoming their mother, becoming a training post—anything to break Gifted's visual tracking. Gifted hesitated for half a second, and Kelvin struck from his true position, a spinning heel kick that caught Gifted's shoulder and sent him stumbling.
"Better!" Gifted recovered with a back handspring, landing in a crouch. "But predictable!"
They clashed again, and this time neither pulled away. Punches became blocks became counters became throws. Kelvin felt Gifted's knuckles crack against his forearm, felt his own elbow graze Gifted's ribs. They moved through the dust like dueling storms, and Cavil watched without expression, without intervention.
Kelvin tried the Substitution Jutsu again, but Gifted anticipated it—his hand closed on Kelvin's wrist before the seal completed, and he pulled, using Kelvin's own momentum to slam him into the ground. The impact drove air from Kelvin's lungs, stars exploding behind his eyes, but he rolled immediately, avoiding Gifted's stomp by centimeters.
"You're faster," Gifted admitted, breathing harder now. "But you're still thinking in sequences. A, then B, then C. I just... go."
He demonstrated, attacking in a blur of motion that seemed to come from three directions at once. Kelvin blocked two strikes, took a third to his thigh that numbed his entire leg, and retreated, limping, forcing his chakra to compensate.
They fought for ten minutes. Twenty. The sun touched the horizon, then dipped below it, painting them in twilight purple.
Kelvin's body screamed. His reserves—expanded by a week of brutal training, supplemented by his mother's pills—were draining fast. Gifted looked no better: a cut above his eye bled freely, his left arm hung slightly wrong, and his usual grace had degraded into something desperate, hungry.
"Clone Jutsu," Gifted gasped, and three translucent versions of himself stepped forward, moving in imperfect synchronization.
Kelvin closed his eyes.
Not thinking. Knowing.
He felt the chakra signatures—two faint, one strong. He attacked the strong one, driving his palm through the illusion's chest and into Gifted's real sternum. The clones dissolved. Gifted coughed blood, stumbled back, and smiled.
"Finally," he whispered.
They collided one last time, neither defending, both attacking, a mutual destruction of fists and elbows and knees. Kelvin felt his nose break, felt ribs crack, felt consciousness flickering like a candle in hurricane wind. He saw Gifted's eyes rolling back, saw his body beginning to fall, and threw one more punch—a wild, hopeless thing that connected with Gifted's jaw and sent him falling too.
They hit the ground simultaneously.
Dust settled.
Silence.
Cavil walked to where they lay, two meters apart, both unmoving. He knelt by Kelvin first—pulse thready but present, breathing shallow but steady. Then Gifted—similar state, perhaps slightly worse, the blood loss from his cut eye taking its toll.
He stood between them and began to count.
"One."
The evening wind stirred the dust.
"Two."
A bird called, distant, confused by the silence.
"Three."
Kelvin's fingers twitched. His eyelids fluttered. But his body—pushed past every limit, drained of every reserve—refused to obey his will.
"Four."
Gifted's chest hitched. A groan escaped his throat. His right hand spasmed, grasping at dirt, finding nothing.
"Five."
Kelvin's mind screamed at his muscles. Up. Stand. Fight. You promised. You can't lose. Dad is watching. Cavil is watching. The man with the Sharingan is watching. UP.
His body didn't answer.
"Six."
Gifted's eyes opened—slits of consciousness, barely there. He saw the sky, purple and endless. He saw Cavil's silhouette, counting, judging. He tried to move his legs. Nothing.
"Seven."
Kelvin heard the number through a fog of pain. Heard how close it was to ending. Ten, he remembered. Gifted said ten counts. Unconsciousness is victory.
His fingers dug into the earth. His back spasmed, trying to arch, failing.
"Eight."
Gifted rolled onto his side, vomiting blood and bile. The movement cost him everything—his vision grayed, his hearing muffled to underwater silence. But he was vertical, technically, partially, his weight on one elbow and one knee.
"Nine."
Kelvin's eyes opened fully. He saw Gifted's position, understood the geometry of defeat and survival. He tried to push himself up, managed to lift his head six inches from the ground, then collapsed, consciousness finally, mercifully fleeing into darkness.
"Ten."
Gifted—still on one elbow, still technically upright through sheer, stupid, stubborn will—coughed out something that might have been a laugh.
"Default," he whispered. "Victory by... default."
Then he, too, fell unconscious.
Cavil stood over them both, the first stars appearing above, and said nothing for a long time. When he finally moved, it was to lift Kelvin gently—more gently than he'd ever handled him in training—and carry him toward the house where their mother waited with healing hands and fearful eyes.
Behind them, Gifted lay in the dirt, smiling even in unconsciousness, having learned exactly what he'd wanted to know.
They were both still alive.
That meant they could both still grow.
And somewhere, watching through red-tinted eyes, someone noted the names of two boys who refused to die.
