A long time ago, there was once love & peace between the Moon Kingdom & the Earth Kingdom. But they were attacked by invading forces of Earth Condemnation Group Yuumajuu. But to their shock and surprise, they had Guardian Angels from Earth itself from the heavens, they are Gosei Angels, the three tribes of Earth's source that protect life of the planet for a long time. With a combined effort, they seal the Yuumajuu in Erurei Box the Yuumajuu made as both kingdoms had help from legendary warriors they look up to the most. They promise to Gosei Angels to keep secrets about their society as they always fulfill their promise that day. Later on, after the downfall of Silver Millennium from the force of the Dark Kingdom, the Sailor Senshi were reincarnated as new people in the modern day after the seal was complete thanks to the power of Silver Crystal.
