RIDER TIME: Kamen Rider Zi-O VS Decade2021

Horror Vault's take

When a high school is inexplicably cut off from civilization and dropped into a monster-infested wilderness, its students must fight to stay alive against a relentless horde of Inves creatures. The situation grows stranger still as multiple versions of the same person begin appearing, raising unsettling questions about reality and identity. A shadowy connection to the dimension-hopping Decade looms over the chaos. Fans of the Zi-O and Decade corners of the Kamen Rider universe will find plenty to sink their teeth into here.
