The weakest Knight and the largest of the Knights. Kouga is sensitive about his ugliness, due to which as a child he was always treated miserably. He's extremely arrogant and dense, and hates anyone with good looks (e.g Alviss, as he claimed in their fight) as he thinks people with good appearance carries dark hearts. Although his magical powers and ÄRM strength are more along Bishop class, Kouga rose to Knight Class due to his vast amount of strength and a sturdy stamina which takes in unusually low damage from the most destructive of attacks.

Kouga appears cloaked throughout most of the series until War Games' 6th round, wherein he fights 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 then sent them on a mission to kidnap the Caldian Grand Elder, and is later defeated by Dorothy and Ginta. He is last seen (in the anime only) somewhere with Pinocchio and Girom, riding Kung Fu frog. A user of ninja-themed Weapon ÄRMs.
