It tells the story of a "Strange House" grocery store in a downtown neighborhood. The goods in it seem ordinary, but they all have strange functions. The owner Damon recorded their instructions for use in "Strange Notes", and customers can choose items according to their needs. People of all kinds come to the Strange House. They all encounter their own difficulties and want to find a way out of the difficulties, but in the end they always find that the solution to the problem is not these strange groceries, but their love and faith. The play is adapted from the anime of the same name.
