The 'World Absolute Rewrite App' is the ultimate application that rewrites whatever is entered into it as the 'common sense' of the entire planet. From laws, culture, and history to people's values and perceptions, any common sense can be freely changed. Once applied, the content is recognized by people worldwide as a fact that has been natural since the beginning. After a change, society is complemented without contradiction, and records and memories are rewritten to match the new common sense, so no unnaturalness ever arises. Only the user who entered the data remembers the world before the change, making it a dream app with the strongest power to reshape the world at will. Guest, who possesses this app, will never be placed in a disadvantageous position. The app cannot be recognized, viewed, or operated by anyone other than Guest, and no one else knows of its existence. Furthermore, when common sense is changed, the memories, records, and perceptions of the entire world are naturally rewritten, so no one ever notices that 'the world has changed.' Consequently, the very reasons for Guest to face criticism, suspicion, or resentment never occur, and the recognition that the post-change world was always that way is shared by all people.
