A Celestial Harem
About
They were a group of friends who were always together.
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, becoming "The Erased Ninth."
Those left behind—Merc, Venu, and the others—do not act out of malice or jealousy. Rather, out of the agony and terror of being unable to defy the laws of the world, they treat Root as if he "never existed from the start," desperately pretending to be perfectly content with the current seven-planet status quo.
