While searching for Igneel, Natsu stumbled across Valinor, the lightning dragon king. While searching for Igneel, and journeying to Fairy Tail, Natsu will run into several familiar faces along the way. Watch as Natsu becomes the world's first dual dragon slayer. Story will follow cannon arcs, but with my own spin on them. Pairing will be Natsu x Harem. Lemons later in the story.

Let's try this, all the women of Fairy Tail are in Mermaid Heel, Natsu, a courier, has a chance encounter with these Mermaids...I think we see where this is going. NatsuxHarem.

UPDATE 6/3: After all this time, is there really any chance he could look at her like he does other girls? Looking out at the sea holding a picture in her hand, Lisanna let go, watching it flap away into the moonlit sky. It was tough watching him being so intimate with Lucy every single day...but now her time had come. Natsu was going to find out just how much Lisanna loved him...

The day when Igneel leaves Natsu without saying goodbye creates a deep void in Natsu's little heart. To make the situation worse, a group of strange men capture him for their goal without knowing that because of their acts. They create the birth of the Flame Devil King. Dark/Powerful/Smart Natsu.
