Of Dragons, Demons, and Devils

Natsu Dragneel is a dragon slayer, mostly anyway. Of course, when you're a dragon slayer unlike any other, issues tend to pop up. There's the ever present desire to show his worth, but not against ordinary mages. There is also the desire to find a mate, and one platinum blonde certainly isn't helping. And there's always the promise he made to Zeref about fighting a death god.
