And that concludes our- Wait, what? Isn't this thing only supposed to have 13 arrangements?
Well, just like the enigmatic Organization, this set of 13 contains a surprising 14th member. Xion's theme, also known as "Musique pour la tristesse de Xion" ("Music for the sadness of Xion"), is one of the most popular character themes of the series, quickly garnering the attention of fan-arrangers everywhere even before the English release of 358/2 Days.
This song plays during what is arguably the most heart-breaking scene of the series: Xion's death. After spending the entirety of the game grappling with the question of her existence, Xion decides to do what she believes is right and return to Sora. Knowing that she and Roxas cannot coexist, Xion engages him in battle, forcing him to absorb her.
As a memory-based replica, Xion's destruction means erasing every memory of her. Though Roxas immediately begins to forget Xion after the battle, he pulls his memories together long enough to cradle her dying body. Needless to say, Roxas wasn't the only one crying as Xion's form iced over and dissolved into the sunset.
