Chibi-chan, a middle school girl, can go no further than 2km from the sacred tree that servers as her town's symbol. That is her "disability".
Then one day, a mysterious figure arrives in town to help the girl's wish to leave, her name is Rokushaku-sensei.
Guided by Rokushaku, Chibi attempts to bypass her "disability" by going to "Nedoko", backroads that can transport her to another location.
However, those places are part of a mysterious world, filled with mysterious creatures.
In her desire to see the world, Chibi-chan will have to triumph over these "Nedoko".
