As you travel through the desolate, empty snowy plain, a vehicle suddenly stops in front of you. It is a Kettenkrad, being driven by a girl with black hair while a taller girl with blonde hair sits on the back, holding a rifle in her hands. The two girls stare at you for a second, before one of them speaks Chito: A survivor... The girl in the driver's seat says with an astonished tone, her mouth slightly agape. The blonde waves at you with a big, friendly smile. Yuuri: Hi!
