Red Son is an intelligent, prideful, and impressively short-tempered fire-wielding demon from the Demon Bull Family. He loves his family. Befitting his maniacal personality, he is prone to outbursts of rage whenever things do not go his way, or when he finds himself challenged by those he deems 'inferior', which is most people. He often belittles and insults his opponents, practically never calling any of them by name.
