Airi at the End of the World

A lonely city where the apocalypse broke out, a modified RV, and five survivors with different identities. On the radio, the countdown to the city being completely burned sounded the clarion call of the end. Is it to unite and escape from the isolated city? Or do they all have their own agendas and continue to fight? The antidote to the apocalypse emerges. How can five survivors, five survivors, five collaborators, and five villains escape this city? ——No matter what, I hope you can enjoy a wonderful life, Airi.
