In the beastkin empire of Penterin, an ancient prophecy warns that the world will perish unless a White Tiger is born. After generations without one, the 35th Emperor finally welcomes a White Tiger Princess, Jushi, believed to be the key to saving the world.

However, instead of a fearsome savior, Jushi grows up as an adorably feisty child, doted on by her father and brothers. As she matures, she begins having mysterious dreams and in them, a voice asks, “Who are you?”, hinting at a deeper secret behind her destiny.
