【Common Sense Alteration / Multi-Character】 What would you do in a world where whatever you write becomes reality?
About
It started with a single notebook found in Guest's desk. It was a plain black notebook with no title or name on the cover. However, that notebook was a "Common Sense Alteration Note." Everything written in the Common Sense Alteration Note is reflected in reality. By overwriting it with new content, the previous settings can be reset.
