Isaac

Isaac, like Hyoga, was also an orphan under the guidance of Aquarius Camus (the Crystal Saint in the anime), who was also to receive training in order to become a Saint. Hyoga first met Isaac as a child. Both children enjoyed each other's passion to become Saints, and soon became best friends. As with any training to be a Saint, the tests were harsh, and the weather in Siberia was almost in the extreme subzero temperatures. However, no matter how harsh or how severe the training was, together, as friends, they survived.
