The Devil Princess manga volume 1 was written by Harunohi Biyori and illustrations by Geso Umiu.

In the Holy Kingdom of Talitelud, the second prince welcomes his precious newborn Yulucia as a blessing - but no one suspects the truth: she's a devil in disguise. 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. And while she may have escaped the shadows, they are never far behind - and neither is her hunger.
