Rider Wars Start

Rider Wars Start (ライダーウォーズ開戦) is the seventeenth episode of Kamen Rider Build. It features the debut of Kamen Rider Cross-Z Charge and the full debuts of Kazumi Sawatari, Akaba, Aoba and Kiba.

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?
