Summary: Lucy Heartefilia was a mermaid, that fell in love with a human. (Basically a Nalu version of 'The little Mermaid') This is my first fanfic!

Disclaimer: I do not own Fairy Tail or The Little Mermaid, they belong to Hiro Mashima and Hans Christian Anderson

People thought mermaids were just mythical creatures and didn't exist, like dragons and fairies. But who could prove that? Well I can tell you one thing: mermaids don't have souls. Nope, they don't have souls like humans, when they die of whatever reason, they just pop like a bubble. This is a tale of how a mermaid got a soul.

"We'll be back soon!" Levy called back to the castle, as she swam away with her sisters.
Lucy sighed, she really wanted to go with them, but she had to be fifteen before she could do that.

"You should be careful because the world above is scary and full of danger!" Layla Heartefillia shouted back to her older daughter that has just turned fifteen.

"We will!"

"I wish I could see the world above the sea..." muttered Lucy as she watched her older sisters swim away.

"You can't go until you're fifteen."

"Sigh",Lucy thought "I can't wait 'till I'm fifteen."

*time-skip*

"We're home!" Shouted Levy as she swam in the huge doors of the castle.

"Sis, what did you see?" Lucy eagerly asked as she went to greet her sisters.

"I saw the beautiful lights of the city!" exclaimed Ezra, being to oldest of the sisters, she saw the most beautiful sights out of all of them.

"I heard the bell ringing from a nearby church." boasted Cana as she combed her wavy brown hair.

"I saw a very tall tower!" Levy eagerly told Lucy what she had seen.

"I'm so sick and tired of those things now, I like it here back at the castle the best." said a very bored Erza.

*time-skip*

"Happy birthday my dear!" said king Jude to his daughter "you finally turned fifteen, now you can go and see the world above!"

"Thank you father!" Lucy excitedly replied, she couldn't wait!

After the party Lucy swam up above to the surface of the sea. What she saw made her gasp! She saw the most magnificent ship she has ever seen!

"Oh how amazing!" she gasped.

"Happy sixteenth birthday, prince."

"Thank you" Natsu said looking out to sea.

A/N I hope the ending wasn't too confusing! This is my first fanfic so please tell me if I'm doing something wrong! Hope this chapter is good enough!
