Sougo, Geiz & Woz transform into Kamen Rider Zi-O, Kamen Rider Geiz & Kamen Rider Woz respectively. As they fight the Another Agito, their count increase gradually one after the another. Another Agito is turning G3s into Another Agitos.
Now there are three Another Agitos standing in front of them. They now try to attack Takahiro Omuro.
