Shōsei

Star of Leadership (将星 Shōsei) is a star belonging to the Nanto Roku Sei constellation and symbolizes supremacy. It is also called the Pole Star (極星, Kyokusei) and the Star of the Southern Cross (南十字星, Minami Jūji Sei). Those born under this star will inherit dominion over the other five Nanto Rokusei Ken and are therefore invincible against them.
