There is a stone bridge in a quiet and mysterious town. The town is called "Fog City".
No one knows how long the fog has existed, and no one knows where the bridge leads.
This place is shrouded in a thick layer of fog all year round, just like a fairyland on earth. The fog on the bridge is even worse. Rumors say it is a passage connecting the outside world, but for some unknown reason, no one who went out came back.
