The door didn't open.
It exploded inward.
Wood splintered. Metal screamed. A man stepped through the wreckage, his boots crunching on broken planks. He was large not tall, but wide, his shoulders filling the frame. His arms hung loose at his sides, thick with muscle that had been earned in places where losing meant death. His face was hard, scarred across the jaw, the eyes flat and cold.
He didn't look at the guards. He looked at Arin.
"I've been waiting," he said. His voice was low, rough. "You don't answer my door. You don't wait for permission. You walk in like you own the place." He took a step forward. "So tell me. Who the hell are you?"
The men who had been standing guard pressed themselves against the walls. The scarred man's face was pale. He tried to speak. "Boss, they came for—"
"I didn't ask you."
The man's mouth closed.
Arin didn't move. He felt the weight of the man's presence pressing against him, heavier than the dust, heavier than the heat. The hum in his chest stirred. Not loud. Not warning. Just... aware.
"We came for the woman," Arin said. "The one you're holding. I want to take her back."
The man's eyes narrowed. He looked at Arin, then at Ren, at Hana, at Maya and Dmitri standing in the shadows. His gaze lingered on Ren's katana, on Dmitri's metal arms.
"You came to my place. With weapons. With soldiers." He took another step. "And you want to take what's mine."
"She's not yours."
The man's mouth curved. It wasn't a smile.
"She owes. She pays. That's how the world works."
"She's the only one who can help my sister."
The man tilted his head. He looked at Arin for a long moment. Then he laughed. Short. Flat.
"You got guts. I'll give you that." He stepped back, spread his arms. "But guts don't pay debts. Guts don't buy what's mine." His eyes moved over them again, slower this time. Measuring.
"So here's how it's going to work."
He pointed at the back of the warehouse. "There's a place. Underground. They fight there. Rich people come, watch, bet. Winner takes the pot." He let his arm drop. "You want the woman. You earn her."
Arin's jaw tightened. "You want us to fight."
"I want you to prove you're worth my time." The man's eyes were hard. "You pick someone. One of yours. They fight. Five rounds. Win all five, you take her. Lose one—" He shrugged. "She stays. And you walk out with nothing."
Hana stepped forward. "That's not—"
"That's the deal." The man's voice didn't rise. It didn't need to. "You don't like it? Walk. Now. Door's right there."
Silence.
Ren's voice came from behind Arin. "And if we don't walk?"
The man's eyes moved to him. A flicker of something—respect, maybe. Or recognition.
"Then you fight."
Arin looked at the woman.
She was standing near the back wall, a guard's hand on her arm. Her face was bruised, her clothes torn. But her eyes were on him. Watching. Waiting.
He turned back to the man.
"Five rounds."
"Yes."
"One fighter."
"One fighter."
Arin was quiet for a moment. Then: "Where?"
The man smiled. It was a slow thing, like oil spreading over water.
"Follow me."
The arena was beneath the warehouse.
A stairway led down, narrow, steep, the walls close on either side. The air grew colder with each step. Heavier. The sound of voices drifted up from below—low, excited, hungry.
They emerged into a wide space. A pit, sunk into the earth, its walls reinforced with metal. Lights hung overhead, harsh and bright. Around the pit, rows of seats rose in tiers, already filling with people in fine clothes, their faces hungry for something to break the night.
The man led them to the edge of the pit. "You got five minutes to choose your fighter."
Arin turned to his squad.
Hana spoke first. "I can't. My abilities—they won't work in a place like this. Too many people. Too much noise."
Maya shook her head. "I'm a healer. Not a fighter."
Dmitri's metal arms gleamed under the lights. "I can do it."
Ren's voice was quiet. "No."
Dmitri looked at him. "Why?"
Ren's eyes moved to the ring. "Because they'll know you. The arms. They'll know what you can do before you step in." He looked at Arin. "This has to be someone they don't expect."
Arin understood.
He stepped toward the edge of the pit.
The man's eyebrows rose. "You?"
"I'll fight."
The man studied him. "You don't look like much."
Arin met his eyes. "I've been told."
A laugh. Genuine, this time. "Five rounds. Win all five, she's yours. Lose one—" He spread his hands. "No hard feelings. You walk out. She stays."
Arin looked at the woman. She was watching him. Her face was unreadable.
"I won't lose."
The man smiled. "We'll see."
