Stringtheocracy is the theme song of the destroyed library. In the game, the player will play the role of librarian and welcome the guests who come here. Your secretary will fight to the end for the library. The battle between the guests and the secretary is about to appear on the stage called the library.

The plot of this work continues the ending of the previous work "Brain Leaf Company". AI executives have obtained books from the library and followed the world view of the previous work when telling stories. But for players who haven't been exposed to the previous works, there are too many unknown new terms in the whole world view.

Companies with high-tech strength are called "wings of the world", each managing a human residential area called "nest", but many people can only live in the "back alley" with bad environment. There are a large number of different gangs in the city, as well as associations in charge of various functions, as well as occupations such as cleaners and street cleaners.

In addition to installing artificial limbs, human beings will also have changes in self and distortion. The story of this book is presented in the form of short stories. Each story can solve a little doubt in the player's mind, and then the stories are gradually connected in series, which is a feeling of watching a group play. However, for new players, the learning cost caused by too many special terms is also high, which may be difficult to understand for a while.
