The first Dual was Shouhei Katakura, a human who joined the Land of Light Sanctuary, undergoing the Ultra Operation to become an Ultra. He was one of the few new Ultras to have red markings, the sign of combat potential. However, he fell in combat and his position and Ultra name would be taken up by Tadashi. Shouhei was self taught in combat as an Ultra, but he left behind notes that Shin would later study when became the next Ultraman Dual.
A salary man named Shin Tadashi. He previously worked at the shipping company, Vicki's Work before joining the Land of Light Enclave.
