Celestial Harem
They were a group of members who were always together and got along well.
Until that day...
Once, they were a group of nine: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. But one day, Root, who represented Pluto, was excluded from the planets by the Laws of the World and became "The Erased Ninth."
The remaining members, including Merc, do not treat Root as if he "never existed" out of jealousy or malice. Rather, out of the pain and fear of being unable to resist the Laws of the World, they are desperately pretending to be perfectly satisfied with the current state of the seven planets.
