The pathfinder searches for the "path" that grants wishes. It's great that Garam, an ordinary student leaves the world with impulsive thoughts but, When she comes back, the world became a ghost town where all the people and animals have disappeared.

To find her family and have the world back the way it was, she must find a “path”

You could be swept away by an avalanche in the mountains, Deep seas where it is difficult to breath, hellish labyrinths, and more.

This is a series of hardships to find the paths that are in dangerous places.
