Yodotai Mercenary

The Yodotai Mercenary were warriors and ambassadors at the same time, representing the Yodotai Empire in the foreign lands. They served in the armies of other kingdoms, fighting alongside their warriors, and learning about these foreign societies. When they knew all about the culture, nature, and weaknesses of the target nation, he returned to the Yodotai army and shared the knowledge. It gave the Yodotai generals a great advantage in the battlefield against these nations. It was the only Yodotai warrior who learned to fight alone, far from his brethren.
