Blue Demons

Lightning and Ring each have mysterious powers that allow them to freely manipulate electricity and water, and each time their abilities are discovered, they transfer to another school. In fact, their father, who died when they were young, was a dragon god, and for that reason they both had special abilities. Then, the demons that his father risked his life to seal come to the city after the seal is broken in order to develop the land. The demons are invisible to normal people, but they appear to be thunder and sound, and the two use their abilities to defeat them.
