The Destruction Begins Now

Aruto visits a hospital run completely by HumaGears for his annual medical examinations. Despite being destroyed, the Assassin HumaGear returns with instructions to attack Yua, allowing Jin and Horobi to attack A.I.M.S. headquarters and steal weapons and data on their newest asset: the giant robot Gigers. Doing so allows them to take control of one and use its power to forcibly hack dozens of the hospital HumaGears simultaneously; doubling their casualty output. Jin and Horobi also reveal a shocking truth about themselves to Zero-One and the others before Horobi uses the Sting Scorpion Progrise Key to become Kamen Rider Horobi, who Isamu recognizes as the mastermind behind the Daybreak Incident.
