In the Battle of Spells, Xia's body was not treated in time, which led to his body and magical power being occupied and controlled by a magical spirit that seemed to be a "brain flower". The five consciousnesses in "Curse Back to War" killed Xia to protect Nitrate, but the five consciousnesses did not give Xia's body to Nitrate, but disposed of Xia's body privately, giving him a chance to control his body. Brain flower is a kind of magic spirit, which controls Xia's actions by occupying his body to achieve his own goals. Xia, the character in The Battle of the Curse, was born on February 3rd. He used to be a student at the Tokyo Institute of Pravda and a close friend of Wu Wu. However, after the plasma escort incident, Xia began to think about how to save mankind, and finally embarked on an extreme road and became the pioneer of a magician's paradise regarded by all magicians. Xia's operation method is the operation of the spell spirit, which can soothe and manipulate the spell spirit. This technology is often used as a means of fighting. Xia used to be one of only four super magicians. In the plot, Xia's body is controlled by brain flowers and becomes a threat.
