Getsuga (Race)

Getsuga were a race of people that lived on Earth's moon a couple thousand years before the start of the series. After a long and fierce war with the Balancers of the Soul Society, the Getsuga were permanently sealed on the moon, never allowed to leave. A few hundred years after that they ended up breaking out and had another war with Soul Society. The conclusion of that war resulted in almost the entire racer being annihilated. Only five of the Getsuga remained, and those five were once again sealed on the moon. However, this time, to prevent them from escaping, the Balancers zapped their power.

Overview & History
While very little is absolutely certain about Getsuga aside from what the old Balancers like Joel Goldsmith and Shikyo Fushiawase have relayed, it is known that they were some sort of offshoot of Shinigami. Each one of them had a Zanpakuto, but very few were able to release it. Those who did possessed a Moon Type Zanpakuto. Also, those who did became the leaders of the race. Tensho has remained the leader for nearly 1,000 years before they were wipped out. They were known to worship the Moon God Tsukuyomi and the Sun Goddess Amaterasu, and their powers were said to be derived from their blessings. This is why they became known for possessing control over both the power of the moon and the power of fire, more specifically a black flame. They are also said to be the earliest known descendants of the Kurosaki Clan, which is why current members like Ichigo, Isshin, Karin, and Kazui Kurosaki possess Moon Type Zanpakuto.
