The white hair was the first thing they noticed. Always.
Ren kept it cropped short, military-style, trying to hide the color in plain sight. But in the Sakura orphanage, where every boy was issued the same grey tunic and the same wooden practice sword, white hair drew eyes like blood in water. The sisters called it "unripe." The brothers called it worse. Father Oren called it nothing at all, which was somehow worse than either.
Ren was seventeen today. Seventeen meant the Awakening.
He stood in the courtyard with thirty-two other boys, all of them shifting in the morning cold, all of them trying not to look at the dais where the priest waited. The cherry blossoms were late this year. The trees were bare, skeletal fingers pointing at a grey sky. Ren found that appropriate.
"Stop slouching," hissed the boy beside him—Taro, 2★ Defense, already manifested, already smug.
Ren straightened to his full height. Six feet two inches. He'd grown another quarter-inch in the night, he was certain of it. He'd felt his spine stretch while he dreamed of nothing. Now he forced himself down, shoulders rounded, neck tucked, presenting the smallest possible target. The target of a 0★. The target of nothing.
The priest raised his hands. The courtyard fell silent.
"Today you receive your stars," the priest intoned. "One for the will to harm. Two for the will to endure. Three for the will to restore. Four for the will to perceive. These are the gifts of the Four, the completion of creation, the judgment of worth, the sacrifice of self, the silence of knowing."
Ren had heard this speech seventeen times. Once for each year, watching older boys step forward, watching light descend, watching faces transform with joy or crumble with disappointment. He knew the words better than his own name. He knew what came next.
"Step forward when called. Receive your classification. Become what you are meant to be."
The first boy stepped up. Akira, small, nervous, hands shaking. The priest touched his forehead. Light descended—golden, warm, the color of approval.
"One star," the priest announced. "Attack. The will to harm."
Cheers from the crowd. Akira's face broke open, relief and terror in equal measure. He would be a soldier now. He would kill, and be killed, and be remembered as a number in a ledger. He was grinning.
Ren watched his own hands. They were steady. They were always steady. He'd trained them that way.
The ceremonies continued. Two stars. Three. Four. The courtyard filled with light of different colors—red for Attack, blue for Defense, green for Repair, silver for Watch. Boys embraced their guardians as they manifested. A wolf of moonlight. A ceramic turtle. A thousand eyes that blinked in unison.
Ren catalogued them automatically. Threat assessment. Habit.
Taro stepped up. The priest touched him. Light—blue, solid, dependable.
"Two stars," the priest said. "Defense. The will to endure."
Taro's guardian manifested immediately—a stone wall given legs, silent, stoic, already positioning itself between Taro and the world. Taro beamed. Second-class citizenship. Better than third. Better than fourth. Infinitely better than none.
"Ren."
His name. His turn.
He walked to the dais feeling every eye on his white hair, his too-tall frame, his wooden practice sword that he carried always, pointlessly, because 0★ weren't issued steel. Because 0★ were issued nothing.
The priest's hand was cold. The light that descended was not.
Ren had prepared for absence. For the hollow feeling of classification failed, for the shame of 0★ made official, for the familiar weight of nothing.
Instead, the light was silver.
Not the silver of Watch. Not the silver of any star he knew. It was mercury, it was mirror, it was the color of a question without an answer. It poured into him and through him and around him, and for one terrible moment Ren felt seen—not his body, not his training, not his concealment, but something underneath, something he didn't have words for.
The priest jerked his hand back. His face went slack, then fearful, then furious.
"Nothing," the priest said, too loud, too fast. "Classification failed. Zero stars. The boy is empty."
The courtyard erupted. Whispers, then shouts. Taro laughed, high and nervous. Someone made the sign against evil—not the five-pointed sign of the heretic, but the four-pointed sign of the failed, the empty, the waste.
Ren stood very still. The silver light was gone, but he could feel it still, settling behind his ribs like a second heartbeat. Cold. Curious. Amused.
He bowed, perfect form, and walked back to his place. The boys parted around him. No one touched him. No one would touch him now, not until the quarantine, not until the tests, not until they confirmed what everyone already knew: that white hair meant broken, that Ren was nothing, that he would be cast to the Borderlands or worse.
Father Oren was watching from the chapel steps. Their eyes met. Oren's hands were clasped so tight the knuckles were white. He did not make the sign. He did not look away.
Ren looked down. The silver behind his ribs pulsed once, twice. Fun, it seemed to say. This is fun.
He didn't know what it meant. He didn't know anything, except that he was still standing, still breathing, still holding his wooden sword like it mattered.
The ceremony finished. The boys filed out, newly classified, newly whole. Ren walked alone to the infirmary for quarantine processing. Sister Yuki met him at the door. Her eyes were kind and tired and did not blink enough.
"Zero stars," she said. Not a question.
"Zero stars," Ren agreed.
She bandaged a cut on his hand he didn't remember getting. The bandage came away silver-stained in the candlelight. She burned it without comment.
---
The quarantine cell was stone, three paces by four, with a single high window that showed only sky. They brought him water, bread, a bucket. They did not bring light. The Church believed darkness helped the "empty" accept their condition.
Ren sat against the wall, wooden sword across his knees, and waited for the silver to speak.
It didn't.
For three hours, nothing. The silver behind his ribs was content, patient, watching. Ren could feel its attention like a hand on the back of his neck. Not hostile. Not kind. Simply there, in a way that made his own heartbeat feel borrowed.
He tried to sleep. The silver pulsed: No.
He tried to meditate, the way Father Oren had taught—breath in four counts, hold, release, hold. The silver disrupted the pattern, inserting an extra beat, a fifth count, wrong, wrong, wrong.
"Stop," Ren whispered.
The silver pulsed: Fun.
"What is?"
You. Trying. Failing. Fun.
Ren opened his eyes. The cell was darker than before, or his vision had changed. He could see the mortar between stones, the individual dust motes in the air, the scratch marks where previous occupants had counted days.
Previous, the silver noted. They counted. They defined. They limited. Not fun.
"Who are you?" Ren asked.
The silver considered. The cell filled with light—not the warm gold of 1★, not the solid blue of 2★, not the healing green or perceptive silver of 3★ or 4★. This light was mercury and mirror, the color of the question, the color of undefined.
It coalesced in the corner opposite him. Small. Child-sized. Lean muscle in wrong proportions, silver skin that shifted like oil on water, and where the face should be—nothing. An oval. Smooth. Tilted slightly, as if curious.
"You're not a guardian," Ren said. His voice was steady. His hands were not. They gripped the wooden sword hard enough to hurt.
Guardian, the thing repeated. Definition. Limit. Not me.
"What are you?"
The oval tilted further. The light in the cell bent around it, gravity negotiating, time hesitating.
I am, it said, and the words came from everywhere, from the stones, from Ren's own mouth, from the space between heartbeats, the sixth. The undefined. The fun.
"Sixth? There is no sixth."
Exactly! Delight, real and childlike, filled the cell. No sixth! No classification! No limit! I looked at one through four and said: boring. I looked at five and said: devil, contract, hunger, not fun. I looked at nothing and said: maybe? I looked at you and said: maybe!
Ren's wooden sword was vibrating. He realized he was shaking. "You chose me?"
You chose me! The silver child bounced on its heels, coiled muscle releasing and catching, a predator's grace in a playground gesture. You didn't sleep. You didn't dream their perfect dream. You stayed awake. You stayed awake and you were boring and I was bored and then—
It stopped. The oval faced him directly, featureless, seeing.
Then you smiled. In your sleep. At nothing. At no one. At me, maybe, before I was here. And I said: fun. I said: him. I said: let's play.
Ren didn't remember smiling. He didn't remember sleeping, either. The silver had filled his rest, his dreams, his waking.
"Play what?" he asked.
The silver child extended its hand. In its palm: a pebble. Ordinary grey stone, the kind from the courtyard, the kind boys threw at birds when the sisters weren't watching.
Tag, it said. You're it. Catch me, or be caught. No rules. No definition. Just—
It threw the pebble. Ren caught it without thinking, muscle memory from a thousand training drills, a thousand hours of hiding his skill behind apparent clumsiness.
The silver child laughed. The sound filled the cell, overflowed it, pressed against the stone walls until Ren thought they might crack.
Fun! it declared. You're fun! I'm Kai! You're Ren! We're fun!
"Kai," Ren repeated. The name felt strange in his mouth. Foreign. Right.
Kai! the silver child agreed. The sixth! The undefined! The— It paused, head tilting, searching for words in languages that didn't exist yet. The bee's knees!
"The what?"
Outdated, Kai admitted, without shame. Old words. Old fun. New fun now. Vibe? Is that right? Vibe?
"I don't know what that means."
Neither do I! Kai crowed. Fun!
The cell door was locked. The window was high, barred, too small for a man. Ren had spent three hours measuring it, cataloguing escape routes, finding none.
Kai walked to the door. The silver child pressed its palm against the wood. The wood negotiated—grain by grain, molecule by molecule, becoming something else, becoming open, becoming invitation.
The door swung outward. The corridor beyond was empty. The sisters were at prayers. The brothers were at dinner. No one expected the 0★ to escape because 0★ had nothing to escape with.
Run? Kai asked. Or stay? Your choice. Always your choice. That's the fun.
Ren looked at the open door. He looked at his wooden sword. He looked at Kai, faceless, silver, waiting.
"Run," he said.
They ran.
---
The forest was three miles from the orphanage, across rice paddies that reflected starlight, through a village where dogs barked at something they couldn't see. Ren ran until his lungs burned, until his white hair came loose and streamed behind him, until he forgot to slouch and ran at his full height, visible, undeniable.
Kai ran beside him, sometimes ahead, sometimes behind, sometimes through—appearing on Ren's other side without transition, without sound, without respect for distance.
Faster! Kai urged. They're waking up! They're noticing! Fun fun fun!
They noticed. Torches behind them, shouts, the bell from the chapel tower that meant heretic or escape or hunt. Ren didn't look back. He'd spent seventeen years looking back, measuring threats, calculating concealment.
Not tonight. Tonight he ran.
The forest swallowed them. Ancient cedar, bare branches, the smell of moss and cold stone. Ren collapsed against a trunk, gasping, his wooden sword digging into his side where he'd shoved it through his belt.
Kai appeared on a branch overhead. The silver child crouched, lean muscle coiled, watching him with that faceless curiosity.
You're it, Kai said, and threw a pebble.
Ren caught it. Instinct. Training. The pebble was warm from Kai's hand, or from something else, something that didn't have temperature in the normal way.
"That's not how tag works," Ren managed, still breathing hard.
How does it work?
"You tag someone. They become it. They tag someone else."
Boring, Kai declared. Rules. Definition. Limits. My way: you catch, or you're caught. No rules. Just...
The pebble in Ren's hand shifted. Became heavier, lighter, existed in multiple states. Ren's fingers spasmed. The pebble fell.
Kai was gone from the branch. Appeared behind him. Pressed something into his hand—another pebble, or the same one, negotiated back into existence.
Tag, Kai whispered. You're it again.
Ren threw the pebble without aiming. It curved around a tree, struck a rock, ricocheted toward Kai's head. The silver child ducked, laughing, and the forest bent—the tree Ren had aimed around was now behind him, the rock was above, the sky had become sunset when it had been midnight seconds before.
"Cheating," Ren said.
Cheating implies rules, Kai repeated, delighted. Rules imply definition. Definition implies—
"Boredom," Ren finished. "You said."
I said! Kai agreed. You're learning! Fun!
They played for hours. Or minutes. Time moved strangely when Kai was having fun—which was always, which meant Ren stopped trusting his own sense of duration. The forest became a maze of impossibilities: paths that looped back on themselves, trees that grew sideways, a stream that flowed uphill.
Ren didn't question it anymore. He ran.
His white hair flowed behind him, unmistakable, visible, ridiculous. He'd stopped slouching. There was no one to see, no one to judge, no priest with cold hands and fearful eyes. Only Kai, who saw everything and judged nothing.
"Faster!" Kai called. "You're almost—no, you're not, that was a trick, I'm over here!"
Ren vaulted a fallen log. His wooden sword—still wooden, still ridiculous—caught the light. He'd tried to leave it behind that first night, after escaping quarantine, after finding Kai waiting in the basement with a pebble in his hand and a head-tilt that might have been curiosity.
You carry that, Kai had said. Why?
I don't know.
Fun, Kai had decided. Carry it. Let's see what happens.
What happened was this: a 0★ boy and a faceless silver god, playing tag in a forest that couldn't decide which way was up.
Ren caught movement in his peripheral vision—silver, lean, there. He threw his sword.
Not at Kai. Past him. The wooden blade struck a branch that shouldn't have been in that position, triggering a cascade: branch to vine to rock to the exact spot where Kai would dodge.
The silver child walked into it. The pebble that had been meant for Ren struck his own shoulder.
"Tag," Ren said, grinning. "You're it."
Kai went very still. The forest went very still. For a moment, Ren thought he'd done something wrong—crossed a line, broken a rule, defined something that shouldn't be defined.
Then Kai laughed. The sound came from everywhere and nowhere, a child's delight and something older, something that remembered when the world was whole and didn't care that it wasn't.
"Again!" Kai demanded. "Again again again! You're fun, Ren! You're the bee's knees! The cat's pajamas! The—" He paused, head tilting. "What do they say now? The... vibe?"
"The vibe," Ren agreed, not knowing what that meant, not caring.
"Let's hunt something," Kai said. "Real hunting. With pebbles. You throw, I... encourage."
They found the boar in a clearing that hadn't existed thirty seconds ago. It was massive, tusks yellowed with age, eyes too intelligent for a beast. It looked at them and saw—Ren didn't know what it saw. Something that made it hesitate.
"Your throw," Kai whispered. He pressed a pebble into Ren's palm. It was warm. It was wrong—too heavy, too light, existing in multiple states at once.
Ren threw.
The pebble didn't fly straight. It negotiated with gravity, with air, with the boar's own instinct to dodge. It curved, paused, accelerated. It struck between the eyes with a sound like a temple bell.
The boar fell. Didn't die—Kai wouldn't let it die, Ren somehow knew, death wasn't fun—but slept, deeply, dreaming of forests that made sense.
"Again!" Kai demanded.
They hunted until Ren's arm ached and his white hair was full of leaves and he was laughing, actually laughing, with a faceless god who thought "vibe" was the highest compliment.
"You're still it," Kai said finally, appearing on a branch that overlooked a valley Ren didn't recognize. "You'll always be it. I choose you. You're fun."
Ren leaned against a tree that grew in spirals. His wooden sword was back in his hand—he didn't remember retrieving it. Everything hurt. Everything felt real.
"What am I?" he asked. Not who. What.
Kai's head tilted. The silver oval caught starlight—actual stars, finally visible, the cherry blossoms still bare above them.
"Undefined," Kai said. "Like me. Like us. Like..."
He threw a pebble. It didn't come down.
"Like fun," Kai finished. "Let's do it again tomorrow. And tomorrow. And—"
"And," Ren agreed.
He didn't return to the orphanage that night. Or the next. Father Oren would report him missing. Sister Yuki would burn another bandage. The Definer would begin his hunt, and the Five Devils would stir in their contracts, and the Soul Kings would feel something shift in their architecture.
But in the forest, in the undefined space between a boy who hid and a god who waited, they played tag.
And it was enough.
