Mer-fairy in Naruto (Rewrite #2)

In the human world, there are mystical beings of lore. Mer-folk, dragons, fairies, and elves are but a few of them. Hybrids between humans and these mystical beings are rare, but are not uncommon. However, hybrids between the mystical beings themselves are not only rare, but almost unheard of. Hi, my name is Luna. I am one of the rarest mystical hybrids you can find, a mer-fairy. I am also the last of the mer-folk and the fairies. But, one fateful finding will not only give me a family, but will reveal things that can either lead to the saving of the universe, or the destruction of it.
