On Halloween, ghosts wander around and the town is offering sacrifices to the dead. Because Ikaya was born at this time, she accidentally provoked the ancient demon spirit. The demon appeared to do evil, and the church in the town managed to suppress it through fighting and seal it again. Because the demon is too powerful and the priest has limited power, he can only seal it away for seventeen years. Seventeen years later, the seal will expire and the devil will return to the world. When the demon spirit was sealed, a curse was planted on Ikaya: seventeen years later, Ikaya was turned into a demon puppet to control and massacre the town. Since only the top-notch white magic sealing spell could subdue this ancient devil, the king began to arrange candidates for practicing the sealing spell. The town's priest Troy has mastered the forbidden black magic and plots to seize the magic spell. Trying to personally subdue the devil and drive it to realize his own conspiracy. After being cursed, Ikaya is withdrawn and likes dark and dilapidated things. Later, he was chased by Troy and fled into the deep forest alone. In the deep forest, Ikaya met the evil witch Tata, and learned from the witch that she was cursed by an ancient demon, which unexpectedly gave rise to a strange talent: the speed and effect of learning black magic will be several times that of ordinary people. Tata taught Ikaya black magic, and Ikaya became a black magic witch. In order to avoid Troy's pursuit, Ikaya hid in the family castle and found that the ancestors in the family cemetery had all turned into vampires. The vampire count handed over the top black magic spell to Ikaya for practice. Troy used magic to release the devil early. Ikaya, with all the forces of justice, launched an earth-shattering epic battle with the devil.
