Hashira Ueki died after falling down the stairs, exhausted from overwork. As a child, he had helped to fix up the shrine of the plant god, so in gratitude, the god grants his wish to "live a laid-back life, surrounded by nature, like when he was little." However… he ended up being reincarnated into the middle of a vast wilderness surrounded by deep forest!
