無能令嬢は竜を操る ~偽りの貌で、真の復讐を~

To avenge her mother's murder, a legendary witch masquerades as a useless heiress. Backed by her four elite brothers, she rejects a royal marriage, secretly commands dragons to crush her enemies, and tears down the scheming fake daughter—while these supreme brothers willingly drop to their knees as her most devoted knights.
