After losing his leg as a newbie adventurer, he retired and returned to his hometown in the countryside. Doing things such as collecting medicinal herbs, exterminating magic beasts and wild beasts, and helping with the villagers' farm work, it's hard to decide whether to call our protagonist an adventurer or a handyman. And while doing these things his age quickly approached thirty. One day while searching the mountains for herbs, he discovered an abandoned child. Thinking that he couldn't just leave it, he took it home and raised it until his age approached forty.

After another five years, the protagonist now in his forties is still acting as a pseudo-adventurer in the countryside, however, his daughter—now a distinguished S-Class adventurer—hasn't returned home even once yet...
