The storm had swallowed the sea whole.
Rain hammered against the deck as Hyuna's ship fought its way through the violent waves. The crew had barely managed to keep the sails intact when something suddenly slammed against the side of the ship..
Isaac immediately reached for his weapon.
"Did you hear that?"
Before anyone could answer, a soaked hand appeared over the edge of the deck.
Then another.
A figure slowly pulled herself aboard.
A mermaid.
The entire crew froze.
Dewey's eyes widened as he raised his weapon. Isaac stepped forward, keeping his aim steady. The rest of the crew quickly surrounded the strange newcomer.
Hyuna stood at the center of them, her pistol pointed directly at the mermaid.
For a moment, there was nothing but the sound of rain.
Then Hyuna tilted her head, studying her with a suspicious grin.
"...Well, that's new."
Isaac narrowed his eyes.
"What the hell is a siren doing on our ship?"
