Ryuujin no Saiaikon: Suterareta Hime Miko no Koufuku na Yomeiri

She was a frighteningly beautiful person who was far from human." Kuguu Yuzuki, who was born as a twin shrine maiden in a family that has the power of purification for generations, has a dragon-shaped birthmark on her back that is considered ominous. As a princess shrine maiden, she is tired of being used only by her power as a tool for Mizuki, who gathers the support of the villagers. As if in response to her despair when she learned that her wish would never come true, a cursed god in the shape of a dragon that covered her heavens appeared in the village. Forcibly presented as a sacrifice to her, while her memories of her previous life flash back, the Dragon God Sogyoku appears in front of Yuzuki in her human form and embraces her. "I will never let you go again. You are my one and only bride." A real princess shrine maiden who was offered as a sacrifice in place of her sister. Despair evokes the promise and miracle of the previous life between the dragon god and the bride.
