The rain over Jeju Isle never washed away blood. It only spread it.
Sejin Yun learned this at seven, watching his mother turn to black dust between his fingers. He learned it again at ten, crawling from a mass grave of Ura victims, their faces frozen in the same scream. He learned it now, at seventeen, as his shadow stretched across the cobblestones like a hungry mouth.
The Shade Ura didn't see him coming.
It was crouched over a merchant's body, its elongated fingers peeling flesh from bone with methodical patience. Once, this thing had been a woman. He could see it in the way it tilted its head, the ghost of human curiosity still flickering behind its hollow black eyes.
Sejin didn't hesitate.
His shadow moved before he did. A tendril of pure darkness shot from the ground, wrapping around the Shade's throat. The Ura hissed, twisting, but Sejin was already behind it. His right hand—bandaged, always bandaged—pressed against the back of its skull.
"Mold: Severance."
A blade of condensed shadow erupted from his palm, through the Shade's head, and out the other side.
The Ura crumbled. Its body dissolved into grey mist, joining the rain. For a moment, Sejin stood still, breathing hard. His left hand—the one wrapped in black bandages, the one that thrummed with something that wasn't his heartbeat—pulsed once.
Then stopped.
"You hesitated," a voice said inside his skull.
Sejin ignored it.
"You saw her face. The woman she used to be. And for a breath, you pitied her."
"Shut up," Sejin whispered.
"She would have eaten you. Slowly. From the feet up. That is what Uras do. That is what all of you become, eventually."
Sejin wiped his blade-hand on his coat. The shadow dissolved, leaving his palm clean. He turned and walked away from the corpse—the merchant's corpse, not the Ura's. The merchant had a family. Somewhere. Maybe.
Not his problem.
None of this was his problem.

The innkeeper didn't look up when Sejin entered.
"Late," the old man grunted, sliding a bowl of cold rice across the counter.
"Ura," Sejin said. That was explanation enough.
He ate alone. The other patrons—drunken fishermen, tired guards, a woman with hollow eyes—sat in clusters, laughing, whispering, living. No one sat near Sejin. No one met his eyes. The bandages on his left hand were enough to keep them away. The rumors did the rest.
Shadow boy.
Cursed.
His mother was a witch.
He's already turning. Look at his eyes. Too dark. Too empty.
Sejin finished his rice. He left coins on the counter. He climbed the stairs to his room—a closet, really, with a mattress and a single window that faced the sea. He locked the door. He sat on the mattress. He unwrapped the bandages on his left hand.
The skin beneath was black.
Not burned. Not bruised. Black. Like someone had poured ink into his veins and let it spread. Purple light pulsed faintly under the surface, a heartbeat that wasn't his, a rhythm that didn't match the one in his chest.
"You look at it every night," The Other said. "As if staring will make it disappear."
"I'm checking if it's spread."
"It has. One millimeter since yesterday. At this rate, you have... eleven years. Perhaps twelve. Then the seal breaks completely, and I take your body forever."
Sejin rewrapped the bandages. Tight. "Eleven years is enough."
"For what?"
He didn't answer. He lay down on the mattress, stared at the water-stained ceiling, and listened to the rain. The Other didn't speak again. He never did when Sejin was falling asleep. Even monsters needed rest.
Or maybe The Other was just bored.
---
Three knocks.
Sejin's eyes opened. The rain had stopped. The room was pitch black—no moon, no stars, just the thick darkness of a cloud-choked sky.
Three more knocks.
Not on his door. On the building's front door, two floors down. He heard the innkeeper's shuffling feet, the creak of old hinges, then—
"Lord's men," a voice said. "We're looking for a boy. Seventeen. Black hair. Bandaged left hand."
Sejin was already moving.
He slipped out the window, landed on the awning below, rolled onto the street. His feet made no sound. His shadow wrapped around him like a cloak, dulling his silhouette, blending him into the darkness between the alley walls.
He didn't run.
Running was loud. Running was desperate. Sejin walked—fast, silent, purposeful—through the back alleys of Jeju Isle's lower district. He knew these streets better than the Lord's men. He'd been avoiding them for seven years.
"They're getting closer," The Other observed. "Every month, more questions. Every month, fewer places to hide."
"I noticed."
"You could let me handle it. One night. One conversation. No more Lord's men."
"No."
"You are tedious."
"And you're trapped inside a seventeen-year-old. We both have problems."
Sejin reached the docks. Fishing boats bobbed in the black water. Beyond them, the open sea—and beyond that, other islands. Other Lords. Other people who would fear him, use him, or try to kill him.
There was nowhere to run.
There was only survive.

He found a empty warehouse near the eastern pier. Collapsed inside. Sat against a crate. The rain started again, dripping through holes in the roof, forming puddles on the concrete floor.
Sejin closed his eyes.
He didn't sleep. He never really slept. He just... waited. For dawn. For the next mission. For the next Ura. For the moment when The Other would finally get bored enough to stop asking and just take.
"You're thinking about death again," The Other said.
"I'm always thinking about death."
"Most your age think about girls. Or food. Or revenge."
"I'm not most."
"No," The Other agreed. There was something almost like respect in his voice. "You are not."
Silence.
Then—
A scream.
Not close. Not far. Somewhere in the district, a woman's voice, cut short. Then another scream. Then a crash.
Sejin was on his feet before he decided to move. His body knew what to do. His body had been doing this for seven years.
"Ura," The Other said. "A strong one. Several, actually. Wisps. Maybe a Shade leading them."
Sejin was already running.
"You don't have to do this."
"Yes I do."
"No one will thank you. No one will pay you. No one will remember your name."
"I know."
"Then why?"
Sejin leaped onto a rooftop. Below, in the street, three Wisps were tearing through a merchant's stall. A family huddled behind an overturned cart—a father, a mother, two children. The father held a broken bottle. It wouldn't help.
Sejin dropped into the street.
The Wisps turned. Their hollow eyes fixed on him. They were newly turned—still wearing the clothes they'd died in, still leaking the memories they'd once been. One had been a baker. Another a seamstress. The third... a child. No older than ten.
Sejin's jaw tightened.
"Mold: Severance."
Two shadow blades. One in each hand. He moved.
The first Wisp didn't even see the strike. Its head left its shoulders. The second lunged—Sejin sidestepped, drove his blade through its chest, twisted. The third, the child, stumbled back. Whimpered.
It whimpered.
Sejin's hand shook.
"It's not a child anymore," The Other said quietly. "It's a Wisp. It will eat that family. Then it will find more. Then it will grow. Kill it."
The child-Wisp opened its mouth. Black fluid dripped from its teeth.
Sejin killed it.
One motion. Clean. The body crumbled to mist. The family behind the cart stared at him—not with gratitude, but with fear. The father pulled his children closer. The mother whispered a prayer.
Sejin turned. Walked away.
No thank you. No payment. No one remembered his name.
"Satisfied?" The Other asked.
"No," Sejin said. "Neve
He was three blocks from the warehouse when the arrow hit him.
Not in the back—he heard the whistle, twisted, took it in the shoulder instead of the spine. White-hot pain. He stumbled, caught himself on a wall, ripped the arrow out. The tip was barbed. Flesh came with it.
Four figures stepped from the shadows.
Lord's men. Elite Vessels. Their Source glowed faintly—Terra, Ventus, two Ignis. The leader, a tall woman with a scarred face, held a second arrow.
"Sejin Yun," she said. "By order of Lord Park, you are under arrest for unregistered Vessel activity. Resist, and we kill you."
Sejin's blood dripped onto the cobblestones.
His left hand pulsed.
"Four on one," The Other said. "You're wounded. Tired. Outnumbered."
"I noticed."
"Let me out."
"No."
"You'll die."
"Then I'll die."
Sejin raised his right hand. His shadow stretched across the street, toward the four Vessels. They tensed. The leader notched her arrow.
"You can't win," she said.
"I know," Sejin replied. "But I can make you remember me."
He smiled.
It was not a kind smile. It was not a confident smile. It was the smile of a boy who had died three times already and had stopped being afraid of the fourth.
"I hate you," The Other whispered.
"Get in line," Sejin said.
And then he moved.
