Kanon follows Suzaku to the Kururugi Temple in order to capture Zero; while there, he obtains conclusive evidence not only of the masked terrorist's identity, but also of the existence of Geass. This evidence proves essential in convincing the leaders of the Black Knights to betray Zero. When Schneizel decides to stage a coup d'état, Kanon notes that he's finally made the decision, but seems apprehensive about it. During the battle above Mount Fuji he is appalled by Schneizel's decision to use the F.L.E.I.J.A. warhead to destroy the "Damocles" as a means of killing Lelouch; he is also surprised by Schneizel's willingness to sacrifice Nunnally. He is taken captive by a Britannian officer under the control of Geass, and he looks on as Schneizel himself is taken under control by Lelouch. He is present when Lelouch announces his intention to control the world, and he is last seen being taken to execution along with the others who rebelled against Lelouch.
