Isaac is an ordinary guy from the UK, who was living a normal life, just going through his days, playing online games, and watching good old fashioned anime. One day, a mysterious package arrives for him in the mail from something called the Lobelia Organization. When Isaac opens this package, he finds a strange looking Fruit with a swirly pattern inside. Soon after opening the package, Isaac is transported to the world of Equestria, appearing within the Royal Garden. 

Meanwhile, Princess Celestia is hosting the annual Grand Galloping Gala, when suddenly, she senses the arrival of something strange and dark, little knowing that her Kingdom is about to be changed forever. 

This is the dawn of a new age. 

The Age Of Devil Fruits.
