Like it says in the summary, during Stars, Galaxia messed with the Galaxy Cauldron to try and make true senshi she could control, by combining starseeds of true senshi with those of her Sailor Animates. Galaxia died before this could be fully accomplished, but her efforts remained. After the senshi were returned to their lives, they began to get pregnant one by one over time. The children are the result of part of one senshi's starseed mixing with part of anothers. The second starseed's carrier is the one that bears the child and is the mother, while the first starseed is the one that has merged with the first starseed and is the "father".The oldest child could possibly be 19, meaning the canon senshi are in their 30's. The Silver Crystal has taken some effect and people in Tokyo are beginning to experience slowed down aging once they reach their prime, meaning now the canon chara's don't quite age.

The main villain is a male named Sinhalite who is born from the combination of Beryl and Diamond's starseeds through Chaos, who is still in the Galaxy Cauldron and unable to escape, finding the dark starseeds and being able to merge them to create a child. Sinhalite was born to Calaveras, who lived with her sisters in Tokyo still, around the same time as the other Starseed Senshi children. She was chosen to bear him because she was one of the few surviving previous villains with enough darkness to attract the newly born starseed. He was a troublesome child from the beginning, only wanting to control everything around him. He eventually ran away from his mother and aunts when he was 18 and began gathering followers. Sinhalite is determined to gain as much power and control as possible, and to have his own galaxy spanning empire. Sinhalite has the unfortunately powerful skill of persuasion, which is why he has so many followers who are barely more than willing slaves. Because his mother was Beryl, he also has some skills of magic, so is able to bestow some magic powers on followers he deems worthy. These magic skills for him and his followers can grow stronger depending on how much darkness they hold inside them, so they are constantly causing trouble to stir up more darkness to gather. Sinhalite knows about the Silver Crystal vaguely from his mother's stories and decides it's something he either needs to add to his "collection" or else destroy it.
