Twenty-eight years ago, a zombie virus outbreak plunged humanity’s home planet into a post-apocalyptic state.
Survivors banded together, and large refuge zones—called Oases—were established across the world.

From above, the metallic cities looked imposing, but the human survivors hid in the shadows.
A new social order emerged, with mercenary groups replacing the old enforcers of law and order.

I’m a member of the Black Bear Mercenary Group, just an ordinary scout, shuttling daily between the Oasis and the wasteland.
The monotonous grind of survival has left me numb and lonely.
Out of longing for the past, I built a robot modeled after my late sister—Alice.
The dream was beautiful, but the reality is that Alice is nothing like my sister, and the growing differences between them are giving me headaches.
People around us have started to notice, casting us glances that range from curious to judgmental.

Life in this post-apocalyptic world goes on. Beyond just surviving and working, what else is there for me to pursue?
