Chapter 4: The Smith’s Breaking Point

Heavy footsteps thundered across the planks as the smith burst into the sleeping room. His gaze locked on Yuki’s small form crumpled beside the mat, her skin pale save for the fading red dots crawling up her throat like dying embers. The iron brand on her chest gleamed faintly, the sacred pattern choked by black curse veins now retreating, yet still visible. Too visible.

“Gods… these marks. When did this happen?” His voice cracked. He dropped to his knees beside her, fingers hovering over the marks without touching, as though they might burn him. “Yuki !”

Tetsuya rose slowly.

The smith’s head whipped toward him. “You. What did you do to her?”

Tetsuya met the accusation without flinching. “Saved her. The unbound curse runs faster under strain. The priest’s probe woke it in her fully.”

The man surged up, towering over him. One massive hand shot out, seizing Tetsuya’s tunic collar and hauling him in until their faces were inches apart.

“Saved? She was fine until last night. Tired, but fine. And you… you brought this !” His eyes caught the webs of black veins and the iron brand on Tetsuya’s skin. “Yours are worse. Explain, boy. Now.”

Tetsuya did not struggle. “Release me.”

The smith’s grip tightened, knuckles whitening. “Not until you fix her.”

“She was dying. The unbound curse would have taken her. I bound it. Temporarily.”

Recognition cut through the panic in the smith’s eyes. He released the collar and stepped back as though burned. “Bound it… how?”

Tetsuya straightened his tunic. “The same way I bind my own. Through Kanaya.”

The smith recoiled. “That forbidden ghost.”

“No ghost. Jade-blooded handmaid of the void. Guardian of iron. The bargain binds to blood. Every day I buy with the rite, she must buy with hers. To save us both. Otherwise, until the heart stops from the Heavenly curse, neither can be freed.”

For now.

The blacksmith’s face drained of color. He glanced at Yuki again. Her breathing was steadier now, the red dots dimming further.

“You… prayed to that thing? For yourself?”

“Every day since rebirth.” Tetsuya’s tone brooked no doubt. “I was the Iron Saint. Ambushed. Slain. Reforged in this body by Kanaya’s will.”

Memory surfaced in the smith’s eyes, the cadence, the hidden eighth, the breath, the grip. “Rebirth… old clan tales spoke of Kanaya’s return. But you…”

Tetsuya knelt beside Yuki. “Sacred iron runs in her veins now, the same as mine. The moment their third eye touches her, they’ll smell Kanaya’s touch. They’ll smell the old clan fire they thought extinguished. Then, for their ‘greater heaven…’”

The blacksmith knelt back. His eyes darted between the boy and Yuki’s face.

“You expect me to believe my son died and some dead warrior now wears his skin? I don’t care who you are, demon, ghost, or fever nightmare. You keep those black lines from reaching my daughter’s heart. That’s the only reason I haven’t put a hammer through your skull yet.”

He pointed a shaking finger. “This is not Kotetsu…” he muttered, barely audible, “but it keeps her breathing.”

Silence stretched. Only the coals popped.

Callused fingers finally brushed her forehead, gentle, tracing the faint crimson line Tetsuya had drawn.

“Then what? Watch her waste away? Watch these… things crawl until they reach her heart?” The smith’s voice had calmed, but only slightly.

“Slow it. Teach her the rite. Daily blood buys daily reprieve. Kanaya takes, but she gives time.”

The man’s head snapped up. “Teach a child to bleed for a void goddess?”

“Better than letting the heavens take everything,” Tetsuya answered.

The smith’s gaze flicked toward the window, toward the village shrine. “Prove it. Now. Show me this… Kanaya answers.”

“The rite is once per day. Strongest under moonlight. I already paid at dawn, for her and for me.”

“If she worsens...”

“She won’t. Not today.” Tetsuya paused, calculating. “Tomorrow night, under moonlight, I will show you. But seeing the marks on her face and the character on the floor, you should already know.”

Tetsuya looked straight into the smith’s eyes.

Recognition flickered across the older man’s face, the memory of the Muramasa forge, the blood characters they painted on the floor before every forging, the questions he had asked that were never answered. “Later, you will understand,” they had told him.

Tetsuya saw the moment realization struck.

“You were never fully initiated into the Iron path,” Tetsuya said quietly. “The most important part was skipped, or ignored. You don’t even know the reason for the eight cadence.”

The smith looked back and forth between Tetsuya, the bloody character on the floor, and his daughter. His eyes flooded with both hope and dread.

“Do you know the path? Can it save her?”

“Yes. I can teach you the way, at least part of it. Tomorrow night, I will show you the rite to save her. For now, I need your help.” Tetsuya’s gaze hardened.

The path to the Iron Clan artefacts' rebirth has opened. His daughter will be my leverage.

———<break>———

Morning light crept cold through the shutters. Yuki sat rigid on her mat, knees drawn to her chest. The crimson line on her forehead itched where Tetsuya had guided her limp fingers. She stared at the boy who had Kotetsu’s round cheeks, the same slightly crooked left canine, and the exact same cowlick that Mother used to smooth down every morning.

But the eyes...

Three nights earlier, the real Kotetsu had woken burning with fever and reached for her with trembling fingers. “Yuki… if I get better, I’ll carve you that wooden fox you wanted. The one with the big ears so it can hear the wind.”

She had promised to paint its whiskers red.

Now the thing in front of her had never once mentioned wooden foxes.

Her small voice cracked in the dark. “Kotetsu would be crying right now. He hated pain. He hated blood.”

“Your brother’s gentleness is why the fever emptied him. This shell needed iron.”

Yuki turned her face to the wall so he would not see the silent tears that burned hotter than the brand on her chest.

The smith taught Yuki the rite in whispers: blood lines, claps, and invocations. She learned fast.

“If this keeps my brother alive to fix what you did to us,” she whispered, “I’ll bleed every day.”

By mid-morning, the forge fire burned high. Tetsuya faced the smith across the anvil. “When the priest returns, you’ll speak to him? Convince him to ‘understand’ and help?”

The smith’s jaw tightened, but desperate hope flickered in his eyes. “I’ve bent knee for years. Paid tithes. Kept quiet. Brother Kael knows me. He’ll listen. We’ll explain the boy’s fever made him lash out. Offer extra work. The gods are merciful.”

Merciful as the blade that took my clan, Tetsuya thought.

“Merciful? The heavens butchered my clan and branded every anvil. Iron qi is for us to use. They don’t forgive old iron. They erase it. Talk, and his ‘blessing’ puts us all in quiet graves.”

The smith flinched. “This is our home. Yuki’s home. Flee where? Another village under their eye?”

“Then prepare to fight,” Tetsuya said, fire burning in his eyes, “or die begging.”

The smith’s shoulders folded forward as if the words had added weight to the air. “No fleeing,” he said quietly. “But… I’ll prepare insurance. If the Iron Saint really lives in my boy’s body… if it can keep him alive… what do you need?”

“Throwing knives. Six. Balanced for a child’s grip. And a short blade this body can wield.”

The smith nodded and pulled unmarked ingots from a concealed cache beneath the anvil. As he shifted the pile, a half-finished tanto tang slid into view, its hamon wild and chaotic, before he quickly covered it with a rag.

“Old stock,” he muttered. “From before.”

Fire roared as they worked. Tetsuya took the small hammer, the smith the heavy one. They folded the steel in an urgent rhythm: seven heavy strikes, three light, with the hidden eighth repeated on every turn.

This will be difficult without the sacred qi. I will have to strain myself. Pay the price...

Tetsuya slashed the air once with the fresh blade. It cut cleaner than steel should. Enough for one throat. He tested the balance. Perfect. Child-sized, but lethal. The throwing knives lay beside it, edges humming faintly.

Footsteps approached outside. The same farmer appeared, scythe in hand, but his gaze was sharper now, lingering.

“Master Yokota,” he said cautiously. “Brother Kael passed by earlier. Said the boy showed… unusual strength yesterday. Wrist trouble.” His eyes flicked to the fresh blades cooling on the rack. “The village is talking. He’s returning this evening, with shrine guards.”

“Thank you,” the smith answered. He handed the farmer his fixed plow. The man gave a grave nod, then left.

Tetsuya sheathed the short blade at his side and hid the knives in the folds of his tunic.

“Facade ends tonight,” Tetsuya said quietly.

Yuki stepped forward, her face tight with unease. Her right hand twisted the edge of her sleeve. She looked at Tetsuya, then at her father, but said nothing.

The smith met their gazes. “Don’t worry. I will protect both of you.”

Evening darkened across the sky. Tetsuya stood outside the forge door.

Steps echoed up the narrow trail, measured and deliberate. Brother Kael emerged first from the treeline, his false third eye gleaming beneath the fold. Six shrine guards flanked him, spears lowered. Pale heavenly light shimmered along the spear tips, humming low.

Tetsuya’s fingers tightened on the hilt. His voice carried clear into the red dusk.

“They’re here.”
