Mamoru Miyano
A common trope Clamp enjoys using is identical characters. When the manga "Tsubasa: Reservoir Chronicle" was made, Subaru was envisioned as Kamui's twin brother. Clamp had fun writing this version of these characters despite not being identical brothers. Subaru was intended to have a larger role in "Tsubasa", mentoring the protagonist Syaoran, but he was replaced by Seishirō. As in the original Clamp works "Tokyo Babylon" and "X", Subaru was chasing Seishirō; Clamp decided to reverse this for "Tsubasa", making Seishirō the one chasing both brothers. In "" OVAs, Kamui is voiced by Mamoru Miyano in Japanese and Micah Solusod in English.
