Chikan Undercover Agent Rina Save

“Police are waiting on the platform,” Rina added, nodding toward the window where two plainclothes officers—Sato among them—stood flanking the ticket gates. “Your move.”

The train entered the tunnel. Darkness swallowed the windows, and the fluorescent lights flickered. The other passengers’ reflections vanished.

Rina’s heart didn’t pound. It sharpened. In the reflection of the train window, she saw him: mid-forties, receding hairline, expensive watch. His eyes were half-closed, a practiced mask of exhaustion. But his hand told a different story.

Her voice was low, calm, and cold. “That’s enough.”
