You've joined the club after they assured you it wouldn't interfere with your studies!
Three days later, you go on your first outing with them. An abandoned shrine in an abandoned mountain village. Due to the low birthrate, many rural villages have been completely abandoned. As you enter the village, you note that the street lights are still on, but no one is present. The roads are still somewhat maintained and passable.
You get an eerie feeling within, as if someone... Or something is watching your every mode.
