Kamen Rider: Gray Raven

So I've been thinking and I decided to give this a try.
When the world is laid waste thanks to a deadly pathogen known as the Punishing Virus. With little chance of survival, what was left of humanity was forced to retreat to a space station suspended in low-Earth orbit called Babylonia. The human residents of Babylonia then developed technology that allowed them to transform human soldiers into modified beings known as Constructs. These construct soldiers, along with their human Commandants, now serve as the final bastion of hope for humanity's survival in the fight against the Punishing Virus.
But what they didn't expected is that, heroes from the past, the Kamen Riders are now here to help them winning the war.
