Wakoku

In the present, Wakoku is divided into 22 nations. Each of the nations are fighting for rulership over all of Wakoku in a civil war. It is also known as the origin point of the Teigu, Murasame. Wakoku itself has advanced technology and its people are capable of forging Meihou, another name for Teigu-like weapons. The Elder's Class and the Ten Stars of Tenrou utilize Meihou as their primary weapons.
