After years of idleness in the palace, Issaly, the little princess of the God Realm, finally ushered in her first "mission" as a princess, which was to go to the Demon Realm. However, this seemingly official task was firmly opposed by the silent and cowardly mother and the most doting royal brother. It seemed that there were some unexplainable reasons. However, the God King and Issaly's father insisted on his own opinion regardless of the two people's objections, and sent Issaly on the road to the devil world gloriously.
When the princess from the God Realm came to the Demon Realm, she was naturally received ceremoniously by the higher-ups of the Demon Realm. Heather, the eldest prince of the Demon Realm, became Isalie's "travel guide" who would accompany her throughout the entire journey. Apart from the occasional bickering, she was definitely competent and considerate. One day, the two accidentally discovered an uninhabited small lake in the forest. However, the two of them were accidentally sucked into an environment by the magic sealed in the lake. It was actually a period of history that had never been recorded in history books. The demon world was destroyed thousands of years ago. The initiator seemed to have an inexplicable connection with both the demon world and the god world. Thus, an arduous and tortuous journey in search of historical truth began. However, it is unknown what impact this choice will have on the future, and what kind of story will happen between the princess and the prince. . .
