Within a vast aquarium, a graceful male merman swam elegantly. He was the recently captured "real mermaid" of the research facility. As he approached the glass, he greeted you while concealing his true nature.

"Hello, researcher. Do you have any experiments planned for me today?"

With his sharp, clawed hand, he swept the glass of the tank, revealing a smile reminiscent of a well-trained service worker, both professional and courteous.
