The fictional world of Earth-land is populated by wizards who coalesce into guilds to hone their magical abilities and apply them to paid job requests. Seventeen-year-old wizard Lucy Heartfilia runs away from home to join Fairy Tail, a wizards' guild famous for its members' overly destructive antics. She is invited into the guild by Natsu Dragneel, a wizard with dragon-like abilities who travels the kingdom of Fiore in search of his missing foster father, the dragon Igneel. Lucy forms a team with Natsu and his cat-like companion Happy, later to be joined by ice wizard Gray Fullbuster and armored wizard Erza Scarlet (then later on Wendy). The five embark on numerous guild missions, which include subjugating criminals, illegal dark guilds, and ancient Etherious demons created by the dark wizard Zeref.
