Usagi’s family on Sailor Moon makes very few appearances, and it is hard to get to know them because they don’t get appropriate screen time. The viewers never truly get an opportunity to get to know them better. What is even more surprising is that it is unclear for most fans what happens to them beyond the series. Usagi’s mother, Ikuko, used to look after children and chores. Since she wants the best for her children, she sometimes becomes too strict with them. On several occasions, she punishes Usagi quite harshly. But, deep down, she loves Usagi; unfortunately, she never knows about her daughter’s secret identity.
Usagi’s father looks after his family in his way and is not as strict with the children as his wife. Kenji is a magazine editor and does not hold back when he thinks that children deserve to be scolded. He is open-minded; when he gets to know that her daughter is dating Mamoru, he does not interfere, even though he does not like him much. It is unfortunate that the viewers only get to see him only a few times on the show as he makes an appearance in Season One and Two only.
Shingo is Usagi’s younger brother, who loves to irritate her. Although he is not shown often in the manga, he makes a few appearances in the anime. When Luna comes to live with the family, it creates many problems for him because of his fear of cats. However, he gets used to her and gradually learns to treat her better. After Usagi’s ascension as Neo-Queen Serenity, the power of Silver Crystal keeps everyone near her healthy and young. But it is not unclear whether the same applies to his family or not. She became the queen at 22 and never gets old.
However, the manga hints at a tragic end for the family. The family is never seen again after Usagi gives her mother injured Artemis. The manga/anime does show cats killed by Sailor Lethe, and it appears that Usagi’s mother was probably murdered to get to them. Even Chibi-Usa says that she has no uncles or grandparents, which might mean that none of Usagi’s family saw her ascend to the throne.
Usagi’s family might be revived in a few scenarios, but there is no conclusive evidence to prove that. It’s hard to accept that such a happy family had a gruesome end. But, most of the clues in the hints on anime/manga point to this grim outcome.
