When dragons threaten Equestria, some way of dealing with dragons is what is required. And that way was delivered in the form of a bipedal creature with more clothes than fur, and a flying, talking blue cat.
Natsu and Happy have been sent to Equestria after Natsu ate Etherion in order to try and defeat his toughest opponent yet. But something happened and he was hurled from one world to another. Right off the bat, he is faced with dragons, his specialty, and befriends a group of ponies who fall in love with the concept of Fairy Tail's ideals. Such a chance meeting seems to fit perfectly, but something is amiss in Equestria and Natsu may just be the key to unlocking the answer.
