Spiritists and demons have been enemies for thousands of years. Both have their own injuries in the fight, and it's unclear who has the advantage. It was only thirteen years ago that the two Demon Lords of the Demon Tribe attempted to open the gate between the two worlds so that the Demon Tribe could reach the human world at will. Thousands of spiritualists sacrificed one after another to stop the Demon Tribe's intention. One of the two demon kings of the demon clan was injured and the other was sealed by the blood formation. The fortune teller at that time predicted that sixteen years later, the Demon King would break through the seal and open the door to the two worlds again. How can the young generation of spiritualists save the world again? What life choices will they make?
