Natsu Dragneel was suppose to join the Light Guild, Fairy Tail. But fate had other ideas. Sending Natsu to walk the path of darkness.
Natsu was a typical Dragon Slayer, but the dragon who raised him was the Fire Dragon King Igneel. After Igneel 'disappeared' Natsu wandered in the world alone, until the Dark Guild, Hell's Wrath, found him. As the young boy he was, he didn't know what was right and what was wrong. So he listened to them. Raised in that dark guild, he learnt how to kill, murder, steal, and rob, earning himself the nickname; The Darkness's Choice. The nickname suggests if darkness was to choose a person it favors, it will be someone like him. But, because he was suppose to be in the Light side, he mind can't stand being in the Dark side. So slowly, he'll fall into insanity and that will unlock the demon within him, and everything will be destroyed.
But, on that day, when Darkness's Choice clashes with the Fairies. He runs. He meets a dragon that claims to be him. How is Zeref even connected to this? Can Natsu even save himself?
