A primary character and one of the main antagonists of the show, Gai was Shurato's best friend on Earth, but became his greatest enemy in Tenkuukai when he was put in a spell by Indrah. Unlike Shurato, he is cool, collected, and highly intelligent. He was a martial arts master, depicted as Shurato's equal, even though he was also a pacifist. His shakti and armor are both modeled after the wolf, and his weapon is a sword.
