Many time ago... There were Yin and Yang. Yang was represented as a bloon, and Yin as a monkey. They were in a eternal clash, but then, the ultimate master, Ninja Kiwi, decided to stop the war for now. Then he created the Balance. After too many wars, the world was devastated, and Yang appeared. But now, he is more powerful, because of the badness of the world. As a result, Yin is weak, and he has gone to a Tribe.
