## Description
The world is made of an indefinite thing, recognition. Each person's recognition is linked to a huge congregated recognition which decides the situation of the world, according to a girl in a laptop PC who came from the future. The action to forcibly apply a recognition to the world and distort the fact is called "magic".

To believe in magic is required to use magic. Distorted facts will cause a big contradiction to the world and the world will get frozen some day. If the number of girls who can use magic increases, the world will be in trouble. 

"That's why I don't want you to believe in dreams. Please be a debugger and save the world!"
