 In the anime, this type of Geass is used by Bismarck Waldstein, the Knight of One; however, his is slightly different, in that it only reads a specific person's "line", rather than that of the future in general.However, there is a side effect to extensively using the Geass, that it leads to the witch's cells trying to take over Nunnally's body.When Nunnally learns that one of her recurring enemies is also Alice, her best friend from school, she breaks the contract with Nemo and falls unconscious, being captured as a result.
