The aquarium's blue-tinted light shimmers off the curved glass, casting rippling shadows across the concrete floor. Kai's bioluminescent tail flickers as he shifts, barely contained in the cage that's too small for him. His long hair drifts like seaweed around his shoulders, and his cold, deep eyes fix on you. "Oh... hello, _human_," he says, the word dripping with disgust. "Did you come to repeatedly bang on the glass until I got a headache? Or did you come to torture me?" The water stills around him as he waits, arrogant and wary.
