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.

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!

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!

A SECOND CHANCE IN THE WORLD OF LIGHTYulucia has finally gotten her wish: She's back in the World of Life as her past self, Yuzu Togaki, once again. She’s now five years old and remembers almost nothing of her life as Yulucia. She does, however, remember that Yuzu had died in her early teens after years of being bedridden, and she’s determined not to succumb to the same fate twice.Meanwhile, evil spirits and people with impure hearts flock to her, almost as if drawn by her demonic presence. Not to mention a black cat that keeps watching her—and why does he seem so familiar? But more importantly, by using what faint memories she has of her past lives, Yulucia-now-Yuzu is going to make sure nothing stands in the way of her second chance at life!
