History
Shiro was raised to fight the Annihilators and defend Earth. Her family stepped down from their royal status back in the 48th Century when Crystal Tokyo was attacked.

As the Moon no longer exists (due to Chaos destroying it), Shiro takes the title of Sailor Cosmos and works to fight the Annihilators.
