The heroine fell into the water from modern times and traveled to a mysterious different world. During the journey, she discovered that she could communicate with evil spirits and signed a contract to borrow their abilities. As more and more contracts are signed, the heroine's abilities become stronger and stronger, and at the same time, the secrets of this world are gradually revealed. It turns out that the heroine came to another world for another reason.
Is all this a coincidence? It was already planned! A palace buried deep in the ground, a crying baby deep in the palace, a deviant temple, a devil's cave deep in the desert... This is a fantastic journey, but also a story about love, responsibility and faith.
