Takeru Kamishiro is an ordinary office worker stuck in a dull routine and wishing for change, until a god sends him to Madeus, a sword-and-magic world caught in a repeating cycle of collapse. The god hopes his arrival can save it and gives him a new body with strong magic and enhanced strength, a bag with no bottom, and a skill for finding and appraising valuable materials and treasures. Takeru sets off to wander at his own pace, gathering valuables to sell, with a freshly hatched dragon at his side. Quietly, his actions begin to shift the world's future. The series is a laid-back isekai mixing adventure, comedy, fantasy and slice of life.
