Once a fearsome demon of the shadowy realm, Yulucia longed for a brighter world filled with family, friends, and light. Defying her dark origins, she tore through a summoning gate and was reborn as a human baby.Now revered as the prophesied Saint, Yulucia hides her demonic hunger beneath an innocent facade. But how long can she keep her secret? As dangerous schemes close in and whispers of her true nature spread, Yulucia must balance her love for humanity with the darkness that still resides within.

A DEVILISHLY DELIGHTFUL BIRTHDAYIt’s been five years since the Golden Beast of the Demon Realm was reborn as the baby Yulucia of the Holy Kingdom of Talitelud, and it’s time to celebrate! Thanks to a decree by her grandfather the king, her birthday party is being held at the castle. There, Yulucia finally meets her devious older sisters who try to play pranks on her—only to be met with the little devil’s laughter. What’s more, the four attendants Yulucia’s father assigned to her are lazy, selfish, and greedy—perfect!Just when Yulucia thinks her day couldn’t get any better, the so-called “silver princess” decides to hold a tea party by moonlight. The princess smells of blood and Yulucia can’t help but be intrigued by her invitation. Looks like life as a five-year-old is going to be lots of fun!

FRESH FOES TO FEAST ONSchool bells are ringing and Yulucia—a powerful demon reborn into a human body—is a new student at the Academy of the Magical Arts. As the one and only princess of the royal family, she is rich and powerful. Not only that, she’s a candidate for the Saint! Unfortunately, none of that helps Yulucia to make any friends, and school life is quite lonely.However, one thing she doesn’t lack is enemies. Yulucia’s older sisters still have it out for her, and the Hero’s party isn’t cutting her any slack either. Then one day, she gets an invitation from Duke Kapell. But since the duke resents Yulucia’s family, she’s sure it’s nothing but a trap. This constant harassment would be enough to break anyone down, but the joke’s on them—human malice just happens to be one of Yulucia’s favorite foods!

TO THE FRONT LINES!Yulucia, a demon reborn into a human body, has now been formally recognized as the Saint. So when the daemon army starts invading human countries, it’s time for her to head out with the Hero’s party to fend them off! Yeah, right. Yulucia’s just a ten-year-old girl, no way she’s going to be sent to save the world.Nevertheless, with the situation growing dire on the front lines, Yulucia, Noel the Hero, and Prince Rick the paladin—along with over two thousand people—set off on a journey to face the daemon king and his army. It’s a horribly doomed mission indeed…and Yulucia can’t wait!
