The young girl Lillian dropped into Blood Moon Academy, the highest institution of the blood race, with the silver left behind by her mother. Her blood test revealed that she was a lowly mixed-race, and she was bullied by the pure-blood noble Elinor and others. She rescued the seriously injured werewolf Kane, so she was put on trial by pure-blood law enforcement captain Noah; the human paladin Arthur broke with the family to protect her, and the thousand-year-old mysterious professor Sebastian secretly taught her ancient magic. During the Blood Moon Trial, Lilian activated the power within her body and revealed her life experience: she was the only bloodline of the Blood Moon Queen who was murdered by the four major families and the alchemist Sebastian thousands of years ago. Noah, Kane, and Arthur, who were enemies in the past, chose to follow her and united with the dragons and elves to form a cross-racial coalition to overthrow the old rule that relied on blood to distinguish superiors and inferiors, abolish racial oppression, and reshape a new order of equality on the continent.
