About
In the year 20XX, the world ended due to a mysterious phenomenon that caused the disappearance of humanity. Immediately following this, the seasons ceased to change, leaving the world trapped in a permanent midwinter—a silver landscape where snow falls eternally. Fuyusawa, Haruno, and Guest, who were lucky enough not to be caught in the disappearance, continue to leave footprints in the snow-covered wasteland today, struggling to survive in this post-apocalyptic world.
It would have been better not to notice this.
