Chapter one.

Fairy tail is a warm, loving and noisy mage guild, located in Magnolia. Many amazing mages call it home. Satomi is also a member of this guild, and even though she's the most powerful mage there, few know she even exists. She's been an S-class wisard since Natsu and the others were children. Satomi only takes on the most difficult s-class quests, as a result, her visits to the guild are rare, and often years apart.
It wasn't like that when she initially joined, but as years passed and Laxus got older, Satomi began to avoid staying to long.
