The 40th century, Crystal Tokyo. The faces of the residents who had always lived a relaxed and happy life now have an indelible sadness on their faces. The two siblings who brought joy to everyone in the palace every day no longer smile, and their green faces are mixed with a hint of heaviness and sadness.
In the palace, Queen Serenity and the sailor warriors were busy dealing with state affairs. The king had just passed away in January, and all parties involved and the training of heirs had to be put on the agenda, and the restoration of the Silver Millennium Kingdom on the moon was nearing completion. But although there are many things to be busy with, it does not mean that the queen is so busy that she loses her rest time. Mars and the others looked at each other, looking worried at Queen Serenity's increasingly pale face.
