The Hollow Warriors (Zenless Zone Zero X Kamen rider geats) One-shot ver

In a post-apocalyptic world, there's a super natural disaster called 'Hollows' which is a dimension where monsters known as Etheral are at. Because of that, there's only one urban civilisation called New Eridu that remains. In order for the civilisation to survive, the technology and the required necessities have to be obtained from the Hollows. As humanity is in grave crisis, a group of warriors called Kamen riders is formed to save humanity from the Hollows as they fight against the Etheral and help the victims of the disaster.

Note: I do not own Zenless Zone Zero and Kamen rider. They are owned by Hoyoverse and Toei production respectively.

This is a one shot story so there's 50/50 that it may become an actual story or not.
