Tooru has always been a rather ordinary young man living in modern-day Japan. One day he was taking a stroll with his girlfriend and the two followed a strange cat to a mysterious castle. There, they met an old man who said he was Fermata, the court magician of the Kingdom of Nyuckel located in a parallel dimension where magic dominates over technology. A great war is taking place there. Erion, prince of Nyuckel, was cursed, and his soul transmigrated into Tooru's body. Taking the role of the prince, Tooru must command ten female officers and their armies and repel the invaders.
