Ritsuka was halfway down the ridge when the sky turned orange. She had been tracking the Grin‑Eater through the valley, her steps swift, her En coiled tight. Soru was behind her, his breath ragged, his blade drawn. They had lost the trail at the edge of an orchard, where the ash was thick and the ground was warm, and now the fire was blooming in the hills, moving against the wind, curling toward the village below.
"Captain,"
Soru gasped.
"What is that?"
She did not answer. She was already running.
The fire was not a wildfire. It moved with purpose, seeking, curling around trees, leaping from house to house. Beneath it, a shape, tall and gaunt, its jaw unhinged, its teeth black as coal. Ash‑Grin had stopped running. He was feeding. She reached the entrance of the village as the first houses collapsed.
The streets were empty, the doors open, and the people already hollowed. She saw them in the doorways, their faces smooth, their eyes empty, their mouths open in screams that had no sound. She pushed past them, her blade in her hand, her En rising.
Soru caught up to her, his face pale.
"Where is it?"
She pointed toward the orchard at the far end of the village. Ash‑Grin stood there, his arms spread, his jaw open, black smoke pouring from his throat. He did not see them. He did not see anything. He was feeding, and the village was dying.
"We seal it," she said.
"Now."
She moved forward, her En shaping into a blade of light. She was still twenty paces from the orchard when Ash‑Grin turned. Its eyes were pits. Its face was a ruin. But for a moment, something flickered in the hollows, a recognition, a memory. It looked past her, toward the center of the village, and then it crumbled. Not attacked. Not sealed. Crumbled. Tooth by tooth, ash by ash, until nothing was left but a pile of black teeth and a silence that had not been there before.
Soru lowered his blade.
"What happened?"
Ritsuka did not answer. She walked through the village, past the empty houses, past the bodies that were no longer bodies, until she reached the orchard. There, in the ash where the Grin Eater had fallen, she found the boy. He was small and thin, his clothes torn, his face streaked with blood. He stood over the scatter of black teeth, his hands at his sides, his chest rising and falling. He was alive.
Soru stared.
"He's just a kid."
"Captain," Soru said, his voice tight. "What do we do with him?"
She approached slowly, her hand still raised. The boy looked over his shoulder. His face was streaked with ash and blood. And he was smiling. She did not speak for a long moment. The smoke drifted between them. Then she said,
"You should be dead."
The boy's smile flickered. "I know." He swayed. She caught him before he fell.
She carried him away from the ash and into the hills, to a stream where the water ran clear. The sun was low, the sky grey, and the smoke from the village rose behind them like a wound that would not close. She laid him on the bank and washed his face, his hands, and the wound on his chest that should have killed him. It was already sealed, the skin pink and new, and beneath it, she felt a pulse that was not his. She pressed her fingers to it, and for a moment, she felt something else, a presence, old and patient, watching. Then it withdrew, and the pulse was only a boy's heartbeat again.
She sat back and looked at him. He was young. Too young to have killed a Grin‑Eater. Too young to carry whatever he was carrying. His teeth were white, untouched by En. They were the teeth of a boy who had never bound a Fang‑Cursed, never broken an oath, never known hunger. But she had seen the fire stop. She had seen the Grin‑Eater crumble. She had seen black energy pour from his throat, energy that was not the corrupted En of a Bitten. It was older. Cleaner. It had left no mark on him. She sat beside him and waited for him to wake.
He opened his eyes at dusk. The sky was grey, the stream running clear, and she was still there.
"What are you?" she asked.
He looked at his hands, then at the water, then at her.
"I don't know."
She nodded slowly.
"I am Ritsuka. Captain of Black Fang."
He said nothing.
"The thing that burned your village, I was hunting it. It was a Grin‑Eater, a Hollowed Bitten who had lost everything.I was too slow."
He looked at the scar on his chest.
"It spoke to me."
She leaned forward.
"What spoke?"
"Something in the smoke. Something old. It asked if I would carry it.
I said yes." "Carry what?" He touched his jaw. "I don't know what it is. It didn't give a name."
She studied him, searching for any sign of deception. She found none. He was a boy who had been dying, given a chance to live, and had taken it without understanding the price.
"You bound something," she said slowly.
"But you didn't defeat a Fang‑Cursed. You didn't swear an oath. You have no black teeth."
"No."
She reached out and pressed her fingers to his chest, over the sealed wound. The pulse beneath was steady, human, but when she let her En touch it, something pushed back, not with hunger but with stillness. A presence that did not wish to be known. She withdrew her hand.
"The En you used," she said, "it was not like any En I have seen. It was black, but not corrupted. It did not burn. It stilled."
"You are not a normal Bitten," she said. "You have made no oath, yet you carry power. You have no black teeth, yet you stopped a Grin‑Eater. What you carry, whatever it is, it has marked you. There are things in this world that will sense it. Things that have been waiting for something like you." He frowned.
"What things?"
"Demons. Hollowed. Things that feed on what you now carry." She looked at him, and for the first time in years, she felt something she had thought long dead, hope. "They will hunt you. You will have to learn to fight."
He looked at the water, then at the sky, then at the smoke still rising from the valley where his home had been. "I would rather not fight," he said. She stood. "Then you will die. And the next village will burn. And the next. Until there is nothing left to protect." He looked at her. His eyes were grey, like the ash, but behind them, something was stirring. The smile had faded, but it was not gone.
"Teach me," he said.
She held out her hand. "Then come." He took it.
