Kamui is a supporting character in Tsubasa: Reservoir Chronicle. He is the second of the vampire twins whom Seishirō is hunting, the other being Subaru. He is alternate reality version of Kamui Shirō.
He is voiced by Micah Solusod along with Subaru.
Like his brother, Kamui is a black-haired, thin, tall young man. However he is different to him because of his rush manners, and his rivalry with Fuuma, Seishirō's brother
His personality is similar to X/1999's Kamui's, cold an ruthless, and his relayionship with Fuuma, however, it differs in the fact that Kamui never cared for Fuuma (unlike in X, where Fuuma was beloved to Kamui), fiercely attacking him any time they met.
