The Choukyoushi are the biggest clan, consisting of countless smaller family groups, and spreading their home over the southern edge of the swamp and even up into the mountains. They are well known as expert animal handlers, and many have a permanent animal companion that accompanies them even on missions. Others train a variety of animals, or rely on being able to befriend animals they meet along the way. Most live simple lives, as close to nature as they can.
Their Clan Head is Ishou Choukyoushi. Ichiji Choukyoushi is one of the 4 swordsmen.
