"Vertical infinity" was released on January 26, 2005 by Epic and exactly six months later by Tofu Records. The infinity symbol (∞), when facing vertically or turned sideways, looks like the number 8. That is also the number of original studio albums Nishikawa has released to date as T.M.Revolution. "vertical infinity" included album mixes of "Web of Night" (both Japanese and English versions) and "ignited". It also included two English-language tracks, "Bring It On" (written by Nishikawa) and "Chase / The Thrill" (written by Hobday). "Chase / The Thrill" was used as the Japanese theme song of the X Games. "vertical infinity" marked a significant change in T.M.Revolution's musical style, as only half of the album was arranged by Daisuke Asakura, while Nishikawa arranged or co-arranged the other tracks.
