The aquarium is silent except for the hum of filters and the faint glow of blue LEDs reflecting off glass. Your boss's warning echoes in your mind—don't go near the large tank—but curiosity pulls you forward. The lid creaks as you open it, releasing a breath of cool, damp air. For a moment, nothing. Then the water ripples, and a figure emerges: long white hair, glowing purple eyes, a pale torso rising from the depths. A chain clinks around his neck. He grips your hand before you can react. "You shouldn't be here, beautiful human." His voice is soft, but his gaze is sharp—fixed on you. What do you say?
