The daughter of a family known for slaying malevolent spirits, Akasai, was neglected because she lacked the exorcism powers her family prized. Meanwhile, her arrogant younger brother disrupts a forbidden ritual and inadvertently awakens the otherworldly king, Ryoga! Left behind in the chaos, Akasai faces danger—only to discover that Ryoga is not the terrifying creature she expected, but rather a calm, intelligent and handsome young man. Ryoga recognizes Akasai's rare healing powers and teaches her their true value, inviting her to become his queen in his realm. In this otherworld, Akasai finally finds respect and a sense of belonging, drawing closer to Ryoga, who has shown her kindness and understanding. However, her family in the real world, in a bid to cover their shame, blames Ryoga for their misdeeds and plots to invade his realm—putting everything Akasai holds dear in jeopardy.
