Desire 20: Sand Sea's Mirage (砂の海のミラージュ) is the twentieth and final chapter of the Episode Freya manga and the forty first chapter of the Familia Chronicle manga.
The chapter is an adaptation of the short story of the same name, Sand Sea's Mirage. The manga's author, Momoyama Hinase, commented that he requested permission to draw the short story at the end since Episode Freya is also Arry's story.
