The weakest Knight and the largest of the Knights, Kouga is sensitive about his ugliness, which led to him being mistreated as a child. He is extremely arrogant and dense, harboring a strong dislike for anyone with good looks, such as Alviss, whom he claimed had a dark heart during their fight. Despite his magical powers and ÄRM strength being more aligned with the Bishop class, Kouga achieved Knight Class status due to his immense strength and robust stamina, allowing him to withstand even the most destructive attacks with minimal damage.
Kouga remains cloaked for much of the series until the 6th round of the War Games, where he faces off against Alviss and loses. In a filler episode of the anime, he teams up with Pinocchio and Girom to attack Dorothy, Ginta, and Alviss. After being repelled, Diana sends them on a mission to kidnap the Caldian Grand Elder, but they are later defeated by Dorothy and Ginta. In the anime, Kouga is last seen riding a Kung Fu frog with Pinocchio and Girom. He specializes in using ninja-themed Weapon ÄRMs.
