The sun earrings worn by some demons are often symbolic of power, strength, and dominance. In many cultures, the sun is associated with life, vitality, and energy. By wearing sun earrings, demons may be trying to project an image of being powerful beings who draw their strength from the sun. Additionally, the sun is often seen as a source of light and enlightenment, so demons wearing sun earrings may be trying to convey a sense of knowledge or wisdom as well.
