The letter says if you fill in the blanks in the scrolls, they will lead you to treasures and if you gather all the treasures, something magnificent will happen to the world. It seems the first treasures you are supposed to find are located in Japan and the scrolls are written in Japanese. Fortunately, you have got plenty of time, so you have decided to head for the country to gather the treasures. Now your journey will begin.
