In a world that is very similar to ours but full of magical power, there is a type of person called a copyist. A copyist has the ability to find something from people's memories and turn it into a physical entity. The more detailed things are memorized, the easier it is to successfully manifest them, but no matter how powerful the copyist is, they can only make the entity exist for 15 minutes at a time, and then it will disappear again. In this world, all abilities require the consumption of things containing the same amount of energy. For example, those who can manipulate natural elements need to use ores or other things with natural energy. The copyist, on the other hand, gives his own emotions and uses his own emotions to reproduce the things in people's memories. Those who have the gift of copywriting are sentimental people. While they continue to realize memories for people, they see through the world bit by bit, and eventually become indifferent and no longer moved by the troubled world. The copyist can embody all items that can be recalled, but cannot embody emotions. Even if the embodied person is very similar to a real person, it is just a puppet that acts according to the customer's wishes and memories. There is no emotion in what he says or does. People say that's because the copyist puts in his emotions, and the emotions don't come back.
