Fairy Tail is set in Earth-land where wizards coalesce into guilds to apply their magical abilities for paid job requests. Novice wizard Lucy Heartfilia runs away from home to join Fairy Tail, a guild famous for its members' overly destructive antics. She is invited into the guild by Natsu Dragneel, a dragon slayer wizard 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, which is later joined by ice wizard Gray Fullbuster, armored wizard Erza Scarlet, and dragon slayer Wendy Marvell. The team embark on numerous guild missions together, which include subjugating criminals, illegal dark guilds, and ancient Etherious demons created by the immortal dark wizard Zeref.
