Fairy tail

In a land far far away there is a kingdom called Fiore where magic flourish and those who use magic are called a mage.

Here mages gather together to form a guild and Fairy tail is the number one guild in Fiore.

The Sex Note found itself falling through the air, cascading down and falling on the ground just outside the Fairy tail guild in Magnolia.

The question is, who ends up stumbling upon this magical book?
