Despite Oma-Zi-O being erased from existence as a result, Heure and Swartz found Kasshin's deactivated body and revived him, the latter now reprogrammed into killing present-day Sougo Tokiwa. As Sougo struggled with with Kasshin as a civilian and protecting an injured boy, Geiz barged in and encouraged the future demon king to become Kamen Rider Zi-O again. As Geiz join the battle, Decade joined Kasshin to even the odds before he retreated. While Zi-O DecadeArmor Ex-Aid Form L and Geiz fought the Time Jackers in their respective Time Mazines, the Form R half defeated Kasshin.
