15-year-old Yuna Lee goes for a walk - wallowing in self pity - and promptly falls down a snowy cliff.

Queen Yuna awakens at Elysian and is introduced to her three Guardian Knights, who are actually part of a plot devised by Phantasma's elders. And Rieno has agreed to become Princess Liberia's knight, making Yuna jealous and determined to win Reino over.
