Synopsis
This is Tenmochi Higashi. When Minamin and Chiaki and I fell into a well on the way home from school, it was a different world. There are no people, no civilization, in the mountains. A harsh journey has begun to find a way to survive and return without any tools. I was really impressed when the fire started for the first time! Besides, making threads and stone axes is difficult, but every day is a series of discoveries and impressions! It's really encouraging because the strong Minamin and the honor student Chiaki are together at any time. My hobbies such as handicrafts and picking edible wild plants are useful. Also, Shiba Inu's beastman, Shiba-san, is guiding me, but this kid is so cute! Anyway, we will definitely come back alive!

Authentic JK stone tool survival, the first!
