A celestial maiden born of the heavens and a prince born of the earth meet to weave a whole new interpretation of the swan maiden tale!

“I’m giving you this ring to show that I place my trust in you.” “I will support you so that you become the Emperor.” To save the marriage of her elder sister, which was on the brink of collapse due to an ancient family stigma, celestial maiden Nadeshiko descends to earth to reclaim a certain treasure. Lost in an unfamiliar world, she is rescued by Prince Kikyo, who promises to return the treasure if he ascends to the throne. However, Kikyo was from a maternal clan and was hiding his true, manipulative side: he would scheme, lie, and do absolutely anything to seize power.
