(Course) Ainas, Unicorn Messenger

Lore
"Let's go!" A rainbow bridge stretched across the sky, carrying the high-spirited Ainas and her galloping unicorn. Although she enjoyed their time of rest in the Skyplains, she also relished the thrill of setting out to accomplish her duty. On the far end of the rainbow awaited untold dangers, but she trusted that her partner would carry her back home once more.
