Overview (Goal: 160-220 words):
On April 8th, 2014, a catastrophic event known as the Global Freeze occurred, during which hundreds of people were killed by an assault from mechanical life forms called Roidmudes. This event resulted in a phenomenon referred to as Density Shift. Six months after this occurrence, the narrative follows Shinnosuke Tomari, a former police officer who has been demoted to the Special Investigations Division. This specific division is tasked with investigating the various Density Shift events that have taken place. During the course of these investigations, Shinnosuke is chosen by the Drive Driver, which allows him to transform into Kamen Rider Drive. His primary mission is to battle and destroy the 108 Roidmudes that threaten the world. The stakes of his mission are high, as he must stop these mechanical entities before they are able to eliminate the human race entirely. Shinnosuke's role as Kamen Rider Drive is central to the struggle against the Roidmudes and the ongoing consequences of the Global Freeze.
