Born on August 19, Ryuga Kou is Momoka's childhood friend. He is of Chinese descent and comes from a long lineage of magic masters. The dragon serves as his family's guardian deity. Members of the Kou family possess the ability to predict the future and can banish demons using their magical powers. Ryuga is intelligent and handsome but can sometimes come off as arrogant and sarcastic. In his right ear, he wears a jade amulet that is a family heirloom. He consistently comes to Momoka's rescue whenever she finds herself in trouble. Although he is aware that she has feelings for him, he refuses to acknowledge his own emotions for her.
