These are the Warriors. They are the most tactical and battle-hungry tribe, ready for anything basically. Here is a little bit about them.
Chikyu 地球
These are the Earth elements. They are the strongest of all the elements, and can move mountains. They are very rude.
Misuto ミスト
These are the elements of mist. They don't usually battle, but make the armor for it, and fill the rivers and streams with mist. They are the nicest of the Warriors.
Hono 炎
This element is the flame. They are the best battlers and train the hardest. They mostly do the hunting. The Hono are the most helpful.
Soyokaze そよ風
The Soyokaze make the wind and the river run. They are calm, and meditate all the time.
