During the final years of his life, Hiraku Machio remained confined to a hospital bed with a terminal illness until he finally passed away. Taking pity on the unfair life he lived, a god decides to reincarnate Hiraku in another world where he can live as he pleases. Wanting to try farming in this new life, he is bestowed with an all-in-one "Almighty Farming Tool" that can transform into any useful implement he wishes. Hiraku is then transported to a forest seemingly far from civilization. Here, he plans to build and farm everything from scratch—gradually developing the lifeless area into a thriving new society.
