On the opening day of the Interstellar Academy of Abilities, Su Luo is tested as F-grade, placing at the very bottom of the school. No one knows that dormant within her body are the dual bloodlines of an SSS-grade Nine-Tailed Fire Fox and a Nirvana Phoenix. Even less do they know that hidden inside the Phoenix necklace around her neck is the truth about her parents being murdered. She only wants to keep a low-profile disguise and investigate her bloody vengeance. Yet the dark night crown prince's spiritual entity lingers stubbornly by her feet, the holy son's unicorn rubs endlessly against her hand, and the flame dragon prince's cub wags its tail begging her to pet it. Three of the most powerful men in the interstellar world have unknowingly set their sights on this "good-for-nothing".
