When I woke up, I was a horse, but in human form! Lucania was the favorite horse of the second prince of Radius, who was alone in all his life. However, she loses her life in an attack on Radius. "On the day of Shining, he is in the depths of despair, but you must bring him back to the light...". Lucania receives powers from the goddess and is reborn as a human. She goes to Radius, but he rejects the kindness of those around him and continues to search for her, believing she is still alive after her disappearance. In the darkness of solitude. "I will make her smile." Lucania hides her past like a horse and decides to save Radius from loneliness in the limited time she has.
