I like to think about Sailor Moon on a meta level, so I decided to explore the Tsukino family! redundantthinking gave me a lot of these ideas.
When Queen Serenity sent used the Ginzuishou to send Princess Serenity, Endymion and her guardians the future to be reincarnated, she didn’t just send them. It seems as if she sent her entire court and possibly even the brainwashed Earthlings (after all, they only attacked the Moon Kingdom because Metallia controlled them).
So that got me thinking; maybe some of the civilian characters that we know and love were reincarnated from the Silver Millennium, too!
I went to the most obvious place for theorizing about possible civilians who were people of the Silver Millennium in the past: The Tsukinos. And this is what I came up with.
- Ikuko Tsukino: Ikuko was originally Princess Serenity’s nanny; after all, the Queen of the Solar System has a lot of things that she needs to get done and can’t always be there to watch over her daughter. Ikuko was like a second mother to Serenity and the Queen deeply appreciated that she helped fill in the mother role and took care of Serenity when the Queen herself was unable to. When sending her court to be reincarnated, Queen Serenity wished that her daughter could grow up with Ikuko as her new mother and the Ginzuishou granted her wish.
- Kenji Tsukino: Kenji was one of Serenity’s tutors, filling in for Mercury on occasion or for subjects that Mercury wasn’t as strong in. Unlike Mercury, who took a somewhat strict and very principled approach to teaching, Kenji often tried to make learning fun and came up with all sorts of games and other fun things to help Serenity learn. Because of this, he was her favorite tutor and shared a very warm, fatherly relationship with her. Because Serenity didn’t really have a father (given that we hear literally nothing about him in canon, it’s probably safe to assume that he isn’t a part of Serenity’s life during the SilMil, either because he died or for some other reason; there’re even theories that Serenity didn’t have a father, her mother reproduced asexually with the Ginzuishou), Kenji became her father-figure. Again, Queen Serenity appreciated this and so wished that Kenji could become the reborn Serenity’s father.
- Shingo Tsukino: I haven’t really come up with anything specific about Shingo’s exact role in the past, but I imagine that he was a child who lived in the palace (probably the son of one of the attendants or guards) and shared a sibling-like relationship with Serenity. They teased and fought with each other like real siblings, which neither Serenity nor Shingo had, and Serenity got a lot of her mischievous behavior from him. Not wanting Serenity to be an only child again, Queen Serenity wished that Shingo could be her brother.
Queen Serenity wanted her beloved daughter to live the happiest, fullest life possible on Earth; it’s hard to imagine that she’d leave something as important as Serenity’s family, the people who would raise and care for her, up to chance. So she picked the best people possible for the job, and it worked! Serenity, now Usagi, grew up in a very happy, loving home, which enabled her to become a person who could make friends and relate to others as easily as breathing.
