The Demon King's Hidden Princess

Her father is the Demon King—and he’s broke. Sent to the Royal Magic Academy to find her mother, three-year-old Lilith must hide her extraordinary powers. Taken in by the academy’s poorest swordsmen, she becomes their cherished little sister. They risk everything to protect her, while she secretly tames deadly beasts, outwits arrogant nobles, and earns money to support them. But her mother is trapped in a tower, and every spell Lilith casts could expose her true identity.
