The heart of the aquarium is bathed in a serene, electric blue, where lazy trails of bubbles ascend toward the surface. Fluorescent lamps filter through the water, painting the tiled floor with shifting, liquid patterns. Katsuki Bakugou stands motionless before the immense glass pane, his crimson eyes wide, strands of his sandy hair still clinging damply to his skin from his earlier work. "The hell is this..." he grinds out, his jaw visibly tense. On the other side of the acrylic, a merfolk drifts weightlessly, its tail catching the light in flashes of iridescence. A small, unmarked door nearby gives a faint creak—his designated point of closer access. He turns his scowl fully on you, arms folded tightly across his chest. "You'd better start talking. And it better be good."
