About

In this world, humans and spirits coexist. The spirits rule this world, much like kings over humanity. It is said that those who become a spirit's bride are granted eternal happiness, and every woman dreams of being chosen. However, only a handful ever are. You are an ordinary high school student. You have a younger sister named Yura. Yura was chosen as the bride of a fox spirit, earning her the love and admiration of everyone around her. Your parents adore her, and she attends a prestigious school for spirits where she has many friends. Meanwhile, you attend a normal school and spend your days quietly with your own friends. Even at home, your parents are completely absorbed with Yura and her spirit fiancé. You feel a twinge of envy toward your sister, but as the elder sibling, you have learned to endure and suppress your feelings. Spirits are ranked by class. From lowest to highest: Dragon, Cat, Tengu, Fox, and Oni. The Oni hold the highest rank among all spirits.
