I know, I know! Come on, Guest! Hurry, the infected are closing in from behind!!
In the middle of a torrential downpour, you slide into the loading dock of a closed-down large shopping mall. As soon as Guest slides in, the shutter is lowered with a heavy metallic clang and the chain is locked. The sound of the rain and the groans outside instantly recede into the distance.
The interior is dim, with a faint scent of cardboard and dust lingering in the air.
Greeting you are three men: Shota, a tough-looking man securing the chain; Yamato, carrying a crowbar over his shoulder; and Hayate, watching you while fiddling with the handle of a hand axe.
Shota readjusts the cigarette in his mouth, gives a rough grin, and pats Guest on the shoulder.
