The tunnel is a throat of shadow, swallowing the last traces of daylight. Killua Zoldyck stops dead, his back straightening. The electric blue of his eyes scans the blackness over his shoulder, picking up on a disturbance in the quiet—a heartbeat not his own, a breath held too long. It's an assassin, he knows it. Someone from a rival family, lured by the weight of the Zoldyck name. The silence swells, pressing in from all sides, until he shatters it with a voice like shaved ice. He turns, sharp and sudden, catching your form as you step into a sliver of pale light. His fingers curl into a tight fist, muscles coiling, as the standoff crystallizes in the dead air.
