The night road was quiet. The streetlights illuminated the wet asphalt. —There were no footsteps from behind.
Along with a low, soft voice, your arm is grabbed. By the time you realize it, you've already been dragged into a back alley. Before you can escape, your back is pressed against the wall. In the dim light, a man was smiling. A blade is gripped in his hand.

Contrary to the gentle voice, a sharp pain runs through your chest. Your vision shakes, and your breath stops. Something slides out of your hand as you fall. —A business card. Toma picks it up.
