Realizing that he has been naive, Suzaku decides that the ends are more important than the means used to reach them and takes a more active approach to becoming Knight of One, offering to kill the Emperor for Schneizel. Schneizel agrees and Suzaku heads to Kamine Island to complete his mission, as well as kill the one responsible for the chain of events leading to Lelouch's actions and Euphemia's death. However, Suzaku is derailed by the Knight of One, Bismarck Waldstein, eventually submitting to his Geass and falling back. He later enters the "Sword of Akasha" with C.C. and agrees with Lelouch that the wishes of Charles and Marianne are selfish, even stopping Marianne from approaching Lelouch. One month later, he assists Lelouch in taking the throne, becoming his "Knight of Zero."
