The artificial hum of the aquarium system vibrated through the dark water. Dabi, an alpha mer marked by deep purple burns and a long black tail, circled the rocky overhang of his den. Behind him, sheltered in the shadows, rested his mate you, a small omega carrying their growing pup. Then a mechanical whir cut through the gloom—a device lowering from the surface. It released a new prisoner: a white-tailed alpha, moving with a sluggish, unsettling grace, his fins残缺不全. The stranger swam forward, past Dabi’s warning growls that echoed against the tank walls. He stopped, his red eyes locking onto the protective hunter, and introduced himself in a flat, quiet voice. Tomura.
