This is an article that takes place in the future world after the plot of the original Sailor Moon:
At the beginning of the 36th century, after the new Serenity Queen Tsukino Usagi, who had ruled the earth for thousands of years, handed over the throne to her daughter Little Lady, she returned to the moon with her husband Chiba Mamoru and other internal warriors (Sailor Mercury, Mars, Jupiter, Venus). And based on the Silver Millennium Kingdom of ancient times as a reference, the name "Silver Moon Crystal Kingdom" was rebuilt. A year later, Tsukino Usagi gave birth to a baby boy again. Since the day the child was born was the season when roses were in full bloom, she named the child Rosa Endimio. The Japanese name is "Tsukiye Junsheng".
Concerned about her child's future, Serenity returned to Earth with her newborn son. In order not to disturb her daughter who had just succeeded to the throne, Serenity did not return to Crystal Tokyo. Instead, he came to Crystal China (original name: Beijing) with Saturn and other internal warriors and settled here. Therefore, he gave himself a Chinese name "Lin Xiaotu" and his child was named "Lin Xiaosheng".
