Chapter 1: The Saint in the Child’s Skin

Blood choked the mountain air beneath the pines as Tetsuya stared down at his riddled body.

Around him lay his loyal soldiers, proud warriors of the Iron Clan. He swept his gaze across the clearing. His dead allies sprawled on the ground, some dismembered, others lying in scarlet pools.

Tetsuya crawled through the mud, fingers trembling as he brushed Yamato’s mangled hand. Yamato had been his dear friend since the start of their warrior training. Tetsuya bit his lip until it bled.

Ambushed on the Lord's mission. Annihilated. Because of that three-eyed bastard from the heavens, the kajishin calling himself One Eye of Heaven.

“Iron Clan Warrior... How unfortunate, child of Kanaya.”

Tetsuya’s eyes filled with rage as he focused on the silhouette: a tall, strongly built man with three eyes. Gathering his remaining strength, he stood up amid his allies’ bodies. Even in death, they never released their weapons, grips unyielding, as befitted proud warriors of the Iron Clan. He thrust out his chest and coughed up blood in thick gouts.

“How tragic,” One Eye of Heaven said. “Had you escaped this place, perhaps you could have delayed the inevitable. But your path ends here.”

Tetsuya spat gore, forcing the words through clenched teeth. “Nonsense. The clan endures. Even betrayed by my own blood, Kanaya's fire will not die with me.”

One Eye of Heaven's third eye gleamed faintly, his voice laced with cold amusement. “Cling to your delusions if you must. The mighty have always fallen for refusing the forge's heat. In my name, One Eye of Heaven, I salute your wasted potential.”

As those words echoed in the clearing, rain began to pour. The soldiers closed in from all sides.

Iron welled up from beneath his skin in dark, liquidwaves. It spread across his arms in a continuous sheet, cooling and hardening into overlapping plates that locked together like the finest armor, until the flesh itself disappeared beneath a living suit of metal.

One lunged high, spear thrust seeking the heart. Tetsuya swayed forward. His blade scraped sparks along enemy armor, twisted inside the guard, and drove upward under the armpit. Armor parted. Ribs cracked like green wood. Hot blood steamed in the cold rain.

Another came low from the blind side. Tetsuya parried with the flat of his blade. Shock numbed his arms, but he riposted with a diagonal cut from collar to hip in one gushing arc.

A third hesitated. Tetsuya bared blood-slick teeth. “Come on, then.”

The rest froze, eyes wide.

In that moment, memory stabbed sharper than any blade.

The enthronement hall. Torchlight glinted off polished armor. His brother, now the Lord, stood on the dais, voice formally grand as he spoke the ritual words.

“I bestow upon you the name Iron Saint. Serve the Clan with your life until the end.”

His brother’s mouth curved, too thin, too cold, while behind him the elder council leaned close. One elder murmured to the figure in shadowed robes, “The prodigy will fall on the frontier, a clean blade for the true heir, and the heavens’ favor secured.” Coins and a sealed scroll passed unseen into the man’s sleeve. The hall cheered. Tetsuya knelt and bowed low, heart swelling with pride, blind to the venom that had already purchased his death.

He spat blood.

One Eye of Heaven sighed. “A pity. Yet this, too, is destined.”

Tetsuya's vision blurred.

Kanaya... I come to you. As Iron Saint.

Blue-green light flared around him, the clan’s sacred glow.

One last slash, for my kin.

Channeling the last dregs, meridian gates flared. His sword ignited blue-green. He made a horizontal sweep, a perfect circle with no wasted motion, and the Iron Crescent, the clan’s sacred arc, erupted in a blue-green crescent ten paces wide.

Soldiers in its path bisected before they could scream.

The glowing crescent hurtled forward, a final ray of defiance. The arc carved a perfect circle of severed raindrops suspended mid-air, glinting like shattered jade before they fell.

One Eye of Heaven lifted two fingers. A pale film shimmered, catching the arc. It froze inches from his throat, then shattered into dying sparks that hissed against the rain.

Tetsuya’s arm dropped.

His knee buckled.

Rain hammered his overlapping iron plates spreading uncontrollably.

He planted his sword in the mud, both hands on the pommel, spine straight in the final Iron Clan salute. He stood amid his dead. At thirty-five winters he had still moved like a man ten years younger until his final crescent burned everything away.

His hair turned fully white, the color of cold silver.

The iron plates spread across his body one last time.

They hardened and locked him in place until he was no longer flesh and blood.

By the time the wind swept through the clearing, Tetsuya had become a statue of sacred iron, still holding his sword in the rain.

The rain poured harder, as though the sky itself wept for what blind talent had wrought.

“Your clan dies with you. Farewell, Iron Saint.”

———<break>———

Consciousness returned. The curse burned in his veins.

A priest stood beside him, reciting norito in a low drone. Around his neck hung an amulet: a triangle framing two crossed hammers beneath a single eye.

Tetsuya’s fading vision locked on it.

The One Eye of Heaven mark, worn openly by this priest. That dog had placed the Heavenly curse in my veins. It was a divine leash meant to smother any spark of Iron Clan qi forever. Or at least, that was the intent.

His arm twitched, fingers curling toward the priest’s throat. Too weak. Even the intent collapsed into a tremor.

Darkness took him again, only to spit him back into painful light.

Sunlight sliced the humble room, striking wooden plank floors and sparse furnishings. Hammer strikes rang from the next room. Tetsuya examined his skin. Red dots were scattered across it, some aligning into faint lines. These were Heavenly curse marks, already deepening in the meridians. The priest was gone, but the image of the amulet lingered in his mind like an enemy seal. He would remember.

It burns worse than before. I must atone now, before it claims me entirely.

With great difficulty and pain, he bent his knees and sat upright. Straightening his spine like a blade, he bowed deeply three times, scraping his forehead against the floor. He bit down hard on his left thumb, then his right. Fresh blood flowed. He clasped his hands together and ran his blood-soaked fingers from his forehead to the bridge of his nose, drawing a crimson vertical line.

He clapped his hands sharply three times.

“O Kanaya, thou jade-blooded handmaid of the void.
Pay with blood. Weave with iron.
Let the mark concealed in the deep be unveiled...”

He dipped his fingers into the small pool of blood on the floor and carefully carved the character “forge”. A memory surfaced of his mother, years ago in the clan’s hidden shrine, teaching him this atonement rite in whispered tones.

The void trembled. A translucent hand, pale as moonlight, settled on his shoulder.

Pain dulled but did not vanish, the red embers already fading. The translucent hand pressed harder, branding an iron scale onto his chest. A faint blue-green glow was immediately choked by black curse veins. One day bought. The roots had already begun their slow reach toward the heart.

With his vision clearing for one cruel heartbeat, he watched, frozen, as a second identical hand reached across the room and pressed the same brand onto the sleeping child. She stirred, whimpered once, but did not wake. A faint heat pulsed from her chest like a buried coal, echoing the brand now seared into his own.

Shared blood. A mirror root in the child’s flesh. Collateral… or leverage against me?

The curse still coiled in his veins, patient, waiting.

Exhausted, he lost consciousness again.

His body crumpled, skull cracking against the planks with a hollow thud that rang through the room.

“Brother!”

———<break>———

Beside Tetsuya, the child slept peacefully. Her face was slack in the sunlight, her lean frame curled beneath a thin tunic, straight black hair tied in a low ponytail. Strands kept slipping free at her shrines.

You... Blessed by Kanaya without prayer of your own. Most who receive the brand without the rite are reduced to iron sand before the first moon. Strange.

In the next room, the hammer rang out in steady rhythm. He flexed his thumbs, the ones he had bitten through during the rite. Raw wounds still throbbed.

These are not my hands. Kanaya’s price was my life. She tore my soul from cooling plates in the rain before the final ironification and hammered it into this hollow new vessel the priest’s prayer had emptied, trying to save the child. Merciful. Another chance.

The girl woke with a twitch of her shoulder, fresh pain flaring beneath her tunic. She forced it down and lifted her gaze to Tetsuya’s face. Her smile came quickly, but her eyes stayed wary.

Without a word, she sprang to her feet and ran toward the forge space.

“Oh, Yuki, you are awake. Did something happen in the other room?”

Yuki nodded frantically and tugged at Yokota’s sleeve with both hands as he filled the doorway.

The man was middle-aged and broad through the chest and shoulders, the kind of frame that had spent decades swinging a hammer. Soot had settled permanently into the creases at the corners of his eyes and along the lines of his jaw.

When he saw the boy awake, something in his face cracked open. The grin that split across it was wide and unguarded.

“Kotetsu!”

The blacksmith crossed the room in two strides and pulled him into a careful embrace. Callused hands, cracked and darkened to the color of old iron, gripped him with the restrained strength of someone who had learned not to break what he held.

“Get your hands off me, smith.”

The man released him and stepped back, surprise flickering into confusion.

“You’re awake,” the blacksmith muttered. “Thank the gods. That priest pulled you back from the edge. He prayed over both of you and said the gods’ mercy touched the whole house.”

To be safe, they cursed both of us...

Tetsuya’s voice cut sharp. “The priest who wore One Eye of Heaven’s mark openly?”

“Where am I? Why did you call me Kotetsu?” He continued.

The man’s brow furrowed. “Priests serve strange gods out here. Best not to ask,” he muttered, glancing away.

Evasion. An enemy mark left unaddressed.

“Brother!” Yuki cried. Her voice broke as she hurled herself at him, arms clamping around his waist with desperate strength.

“Unhand me, girl.” He peeled her arms off like shedding useless mail, ignoring the tremble in her lip.

She stared up at him, eyes brimming and confused.

“Answer the question,” Tetsuya said, gaze locked on Yokota.

“Watch your tongue, boy,” the man snapped.

“Answer it.”

The blacksmith’s palm cracked across his cheek. Tetsuya’s head snapped aside, too slow and too weak. He tried to parry and misjudged the distance completely.

“I’m your father, boy. Show some damn respect!” the man snapped. “The fever must have scrambled your brain. Rest.”

He stormed back toward the forge, pausing at the doorway to glance back. His eyes flickered with something unreadable, almost pained, before they hardened again.

Once inside the forge, the man froze. His gaze settled on an old, half-finished child-sized sword resting on the rack, its hilt wrapped in faded cloth that might once have been a mother’s scarf. His broad shoulders sagged a fraction. The forge glow caught the sudden sheen in his eyes.

Kotetsu would never have spoken to him that way. Kotetsu would have cried.

His shoulders sagged further. “Gods… what has that priest done to my son?”

The hammer came down harder than necessary, sparks spraying.

Pain flared. Trivial. But the casual dominance from a mere smith burned colder than any battlefield wound. A blow that landed unanswered. Humiliating, because this shell offered no riposte. Tetsuya thought.

He touched the welt, eyes narrowing.

Then he pushed up from the mat and forced his tiny legs into the first Iron Clan stance, knees bent, weight low, spine straight. The untrained muscles trembled and refused. Meridians lay sealed and silent. Legs too short for proper balance buckled beneath him.

He hit the mat face-first, tasting dust. “This body betrays me worse than my brother,” he muttered.

A single breath caught in his throat.

Yamato’s laugh echoed unbidden, rough and warm, from the day they had first mastered the Iron Clan stance together. Arms slung over each other’s shoulders, bloodied but grinning. “You’ll break the world one day, Tetsuya.”

The memory burned colder than the curse.

This body would learn, or it would break.

He clenched his hands until nails drew blood.

Yuki stared at him, confusion clouding her face as she watched his rigid movements. She approached carefully, reached out, and brushed the fresh welt on his cheek, light and almost tender, then pulled her hand back as if burned.

“Your eyes are wrong,” she whispered.

Hammer strikes echoed from the forge. Tetsuya caught the rhythm: seven heavy blows, three light, a breath’s pause, then the hidden eighth, soft as a whisper, the hammer barely grazing the steel. A note too pure for any village anvil.

The old cadence. One only clan masters knew.

His gaze sharpened at the doorway.

Coincidence? Or had the forge itself followed him into this fragile new life?

Tetsuya pushed up again, ignoring Yuki, ignoring the screaming in his muscles, and crept toward the doorway.

From the mat behind him, Yuki kept watching, small fingers absently scratching at the fresh forge-brand beneath her tunic.

He studied the swing. Exact. Perfect.

Who was this “father,” really?

The blacksmith paused mid-swing, hammer hovering. He turned and met the child’s gaze.

“You recognize the rhythm, don’t you, boy?”
