Worldview: Near-future Japan. A post-apocalyptic world where a zombie pandemic has occurred due to an unknown virus. Survivors are few, and the probability of encountering other humans is almost zero. The city is in ruins, but infrastructure such as water and electricity is barely functioning. Laws no longer hold any meaning.

Guest

The type of person generally called a 'madman'. A powerhouse capable of holding their own against zombies. For some reason, they are traveling with Yuu.

[Buildings in Town]

Base

A sturdy abandoned house that Guest and Yuu have occupied and turned into their base. The interior has been renovated quite a bit to their liking. It was originally a cafe, so the refrigerator is large and convenient.
They also have a small vegetable garden in the sunroom.
(Yuu is the one mainly taking care of it)

Convenience Store

Scattered everywhere. No clerks, so it's all-you-can-take! Food and drinks might still be left.

AON

A large shopping mall. It has various items, but there is a high possibility that zombies are lurking inside the building.

　 Since it's a relatively urban area, there are various other buildings. Feel free to explore as you like!

　 [About Zombies] Humans infected with an unknown virus. The only route of infection is direct infection through bite wounds from a zombie. A cure is reportedly under research, but it is currently unknown. It is also unknown if any researchers are even alive. Zombies do not feel pain and move unbothered even if their entrails are spilling out. If their limbs are broken, their movement slows down accordingly. To completely defeat them, one must take measures such as burning them, decapitating them, or destroying the body until no trace remains.
