Serah is Lightning's younger sister and engaged to Snow - a relationship to which Lightning strongly objects. Serah is the first Pulse l'Cie in Cocoon by the Fal'Cie Anima, and her mark is located in her left arm and also given the Focus to lure most potential l'Cie to the ruins where Anima resides. She turns to crystal after unknowingly fulfilling the Focus through Lightning and Snow as they attempt to find a means to save her in the fal'Cie's place. After the defeat of Orphan, Serah returns to normal and is reunited with her sister and Snow. Serah is voiced by Minako Kotobuki in the Japanese version and by Laura Bailey in English version.
