Reborn As A Maid

King Leonis Kingheart was known not only as the greatest king in history of Seraiya, he was also the best swordfighter ever. His life was lived through duty and sacrifice, until he came to die and made only one wish; I want to live again for the sword only. The Goddess of Creation granted him this wish. He was reborn a thousand years later as Jennie Queens. She was born into a lesser noble family in an altered kingdom, with the memories of her previous life intact; she quietly pursues her use of swords again, but has to hide her true skill from everyone she encounters. Through fate, she ends up becoming intimately associated with the royal palace and the princess she saved in her former life, causing her to have a new life which gradually leads her towards her previously attempted avoidable destiny. — Description from novelcodex.org
