Synopsis

At last the war has begun! Instigated by virtue of Hokuto through their prime minister's actions, the Touto government officially instigates the Kamen Rider as their military weapon. "I do not intend to become a tool of war" Sento replies. There is a reluctance in Sento's words though, as he realizes that the outbreak of this war was also due to him creating the Rider System and the Smash. Just what decision will these two warriors make?

Errors

• When Kazumi destroyed a Smash with his powered punch, after the Smash turns into green flame, no human body is seen on the ground, even though Smashes should have turned back into their original human form after they are defeated.
• Also, just before Kazumi run towards the Smash, people are still in the background behind Ryuga, but the next time the camera shows Ryuga again, all those people have disappeared.
• When Banjou transforms into Cross-Z Charge for the first time, the standby tune from the Sclash Driver is inaccurate, as it only loops the beginning part of said tune.
