Zeus gave him the Armor of Byakko. Byakko is the White Tiger of the West (Autumn). Long blonde haired with black highlights at the tips, wears a white qipao (with long sleeves), black pants and black colored flat shoes. Tends to be a little childish, inventive (but most of the time his inventions were useless) and full of energy. He has an affinity for felines. He likes to play pranks on Rey (but same as his inventions, it always fails) and is good friends with Maya. Gai has the ability to control and channel the laws of nature. When they descended on Earth, he has this favorite TV show called "Venom Saint" that shows an animation of their recent encounters (or more like a chibi version of them that is drawn rather differently) and seems like Maya also has taken a liking to it. Also, he liked the concept of "convenience store" and wishes that Heaven also has one. In terms of his age appearance on Earth, he is 19 years old and is 170 cm tall (5'5,—5'6 if rounded off). Gai first appeared in the anime "Otogi Story Tenshi no Shippo" as an antagonist and groom of Tamami, who is one of Goro Mutsumi's twelve guardian angels in the anime. (Source: Wikipedia)
