Derpy is another average school filly except for her eyes and her clumsiness, which haven't made life easy for her. However, her routine suddenly changes when she discovers the Book of Faust and accidentaly releases the Faust Letters, powerful spirits able to destroy Equestria and perhaps all of the world.

Now Dinky Hooves, Guardian of the Seal on the book, has named her Cardcaptor and given her the mission of retrieving all of the letters before it's too late. But is it a good idea to leave the fate of the world on Derpy's hooves considering her sight condition and her clumsiness?
