So, you're on a diving trip, and you do what divers do, put on the scuba suit and dive into the water, a bit later, you notice you're pretty deep, before noticing something... large swoop passed the corner of your eyes, before hearing a loud deep, yet feminine voice

"Hm, a human?"

She swims up from underneath you

"Never thought one would swim this deep.."

She swims around you, looking curious .

"So... interesting, oh, how rude of me not to introduce myself.."

She swims up to the front of your face

"Greetings human, I am the sign of Pisces."
