Kogasu is a shinobi from Yoshigakure, and a member of the Taiyōkami Clan, specializing in the use of Scorch Release and is currently the partner of Osamu Otsutsuki. Due to his innovative skills and mastery over the Scorch Release kekkei genkai, as well as his unorthodox fighting style, he was given the moniker "Taiyokami" (太陽神, Sun God). After serving his country for years on end alongside his best friend Osamu Otsutsuki, he was christened the title of Shukage (守影, Safeguard of the Shadows), just one of several in the different sectors of Yoshigakure.
