Now the two of them, along with other survivors, struggle to stay alive in a post-apocalyptic world filled with man-eating zombies.

And when Ai confesses to feeling something more for Hikaru, it changes everything. After all, the more precious someone is to you, the harder it is to lose them. In a world like theirs, is something like love even possible?
