Set in an imaginary world, the Earth Land, there exists a Mage Guild called "Fairy Tail". Fairy Tail is stationed in the town Magnolia, residing in the Kingdom of Fiore, and is currently governed by Makarov, Guild's master.
Lucy Heartfilia, a 17-year-old girl, wishes to become a full-fledged mage and join one of the most prestigious Mage Guilds in the world, Fairy Tail.
One day, out of pure coincidence, she meets Natsu Dragneel, a boy who is transportation-sick, but very cheerful in nature. However, the thing she does not know is that Natsu is the closest connection to Fairy Tail, as he is a Mage in Fairy Tail.
