Tanaka

An A.R. version of Alternative is an evil Rider associated with the Dark Riders who assumed the guise of the Negatives World counterpart of Tanaka, Natsumi's high school teacher. Though ordered by Otoya to keep an eye on Natsumi rather than kill her, he intentionally decides to attack Natsumi, resulting in Dark Kiva beating him merciless. Alternative is then later destroyed by DiEnd.
