Kenichi, a middle-aged man, is transported to a different world while gathering in the mountains. He survives by using a special ability that allows him to shop online and exchange otherworldly items for goods from his original world. His modern products gain popularity when sold locally, bringing him success. Instead of expanding his business, he prefers a quiet, self-sufficient lifestyle on the town's outskirts. However, various problems begin to appear, disrupting his peaceful existence.
