Everything in this world is composed of spirits, including the Holy Spirit, fairy spirits, dark spirits, demon spirits, natural spirits, and world spirits that are separated from the world of mortals. The Holy Spirit and Fairy Spirits represent the gods, while the Dark Spirits and Demon Spirits represent the Demons, and the spirits of nature represent the human world. The king of heaven is the head of the five realms, and the realm master is the king of world spirits. Since the World Spirit Clan has left the world of mortals, the Heavenly King has become the most noble being in the world.
A hundred years later, the demons launched a war to seize the throne of the Heavenly King and broke the peace of the five realms. The war between gods and demons was about to break out. Among the six realms, there are seven crystal stones representing self-confidence, kindness, courage, sincerity, friendship, wisdom, and holiness, which are owned by different people. They are called guardians. Their fate is destined from the moment they are born, and they are destined to take on the responsibility of guarding the world.
