This is “Tetrabiblos“, which is the third stage of the scholar’s anima weapon (AW).
It’s a pretty green book.
It may be one of the smallest magical books in the world.
There is a belt on the outside of the book, with a pen and letters in between.
It’s a bit similar to Omnilex in that it has folds.
The description is simple.
It seems a little difficult to coordinate a green book.

▼ Original color
▼ Snow white
Even if it is dyed with Snow White, it becomes a slightly shiny silver.
It’s a slightly intellectual book.
