Heyu stood in the dimly lit chamber, his eyes fixated on the massive glass bowl that housed the deep-sea demonic beast. The creature's presence was both awe-inspiring and intimidating, its sheer size and power evident even in its subdued state. Heyu, however, regarded it with a peculiar fondness, as if it were a mere pet rather than a formidable entity capable of untold destruction.

The beast floated languidly, its scales shimmering under the faint light that filtered through the chamber. Heyu, with a childlike curiosity, leaned closer to the glass, his breath fogging the surface. "You look lonely," he murmured, his voice barely above a whisper. "Perhaps you need a friend."

With a mischievous grin, Heyu reached into his pocket and pulled out a small, brightly colored toy fish. It was a simple trinket, its vibrant hues stark against the muted tones of the chamber. Without a second thought, he dropped the toy into the water.

The reaction was immediate and violent. The deep-sea beast thrashed wildly, its massive body colliding with the confines of the glass bowl. Water splashed over the edges, drenching the floor as the creature's agitation grew. Heyu stumbled back, eyes wide with surprise at the unexpected chaos he had unleashed.
