At the beginning of the 36th century, after the new Queen Serenity, who had ruled the earth for a full 1,000 years, handed over the throne to her daughter Little Lady, she returned to the moon with her husband Endymion and other internal warriors (sailors Mercury, Mars, Jupiter, and Venus). And rebuilt the "Moon Silver Millennium" kingdom on the moon. A year later she gave birth to a baby boy named Endymion II. 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 (China) and settled here. As a result, he gave himself a Chinese name "Lin Xiaotu" and named his child "Lin Xiaosheng".
