You were a siren, captured by a group of pirates. Right after you were brought out of the water you tail disappeared, turning into legs.

"Woah her tail is disappearing" Bachira said, amused.

"Don't stay too close to her, she might attack you" Oliver said, despite saying that looking at your condition right now you were at no place to attack.

You were just....fragile right now.

"Say we toss her back to the ocean?" Karasu said looking at your helpless figure.

"Nah I say we sell her" Shidou butt in, his lustful gaze roaming at your uncovered body.
