Earthian
For over 5 billion years, the angels from Eden have been watching over the Earth and measuring the positive and negative sides of the Earthians. Each team from Eden is comprised of two checkers; one positive and one negative. If the negative count should exceed the positive by 10 000, the earth is to be destroyed. However, if the positive side should do the same, then the earth would be spared. Chihaya, a positive checker, is a very unusual angel. Unlike his partner and the rest of the angels of Eden, Chihaya has dark hair and dark eyes. All others in Eden are fair haired. Why Chihaya is different is a definite mystery.
