Shiro Tomoe

He is a new racer in the Orcs GP, aiming to overthrow the Loser King. He is a talented racer with a promising future, but his results aren't great, as he rarely finishes a race thanks to consistently overworking his machine beyond the limit of the engine. Initially being on the verge of death following a Stampede-related incident, he miraculously survived after his heart was replaced by an experimental engine, the Tomoe Drive. However, due to the handicap caused by the weight of the Tomoe Drive and regulation checks, he is no longer allowed to compete in established races.
