Yes, Haruka and Michiru are middle school students like most of the other Senshi, but they do not attend just any school. Mugen Academy is a massive elite complex founded by the Sailor Moon S antagonist (the scientist Souichi Tomoe), where only genius students are admitted.

In the particular case of Haruka and Michiru, they appear to be from wealthy backgrounds. Haruka is a car and motocross racer, active and cool. She is also shown to play the piano in the last Sailor Moon season from the 90s (Sailor Stars). As for Michiru, she is a talented violinist and painter. Her instrument is even used to attack enemies, and becomes some sort of musical trademark for the duo’s appearances as Sailor Senshi. Now, that’s classy!

Faithful reflections of their talents, this pair is an interesting and well balanced combo. Haruka is a tomboy who is pretty much like the wind: easy-going, free and somewhat mischievous. As Sailor Uranus, she also has a protective personality, although sometimes we see her reacting rather strongly.

As for Michiru, she is the ideal complement for Haruka, as she is feminine and kind. Her violin has been described as “the sound of the sea” by Naoko Takeuchi (Sailor Moon’s original creator). When Michiru is angry, she is composed, cold and sharp. She might look frail at first sight, but as Sailor Neptune, she is as effective in battle as Sailor Uranus.

One of the best early examples of how well both girls personalities are combined is shown in episode 93, when Haruka mischievously throws a lemon towards Michiru’s violin and she keeps playing, balancing the fruit.

By now it’s quite clear that this pair is independent. We know that most of the Inner Senshi live with their parents or, in the case of Rei Hino, with her grandfather. But there’s little official information about Haruka and Michiru’s parents. They have lived on their own since we met them, and Haruka even mentioned they had “wealthy patrons” once. Of course that, being famous and having such careers, it’s expected. They even have helicopters to ride to school (as shown in episode 92), which they know how to pilot.

We can only expect that, as Sailor Moon Crystal is more similar to the manga in general, we will see more of those helicopters and other daring scenes both in their daily lives and as Sailor Senshi.

Throughout Sailor Moon S, this pair is shown to have a peculiar sense of humor. When they were around the Inner Sailor Senshi they made fun of themselves, especially Haruka. In episode 92, the other girls took her for a man, as she usually dresses like one and addresses herself as “boku” (a male form of “I”). Haruka did not make an effort to correct that impression until much later, which led to comical situations.

Haruka also flirts with Usagi, who eventually flirts back, once she understands it’s not a serious business. But when Haruka and Michiru are shown interacting with each other, it is obvious their relationship is strong and positive. In episode 94, they talk about kisses with Usagi and the conversation could have lead to jealousy. Instead of that, Michiru states that people want to make the most of their first kiss and glances at Haruka, who stares back and chuckles. So, flirting is just a game and they know it.

Again, in the case of Crystal, these two girls might be more flirty when they interact with Usagi and her boyfriend Mamoru. That would spice things up a little!

With such stylish personalities and their independent natures we can only expect that Sailor Uranus and Sailor Neptune are more into the adult world than the Inner Senshi. The contrast is especially prominent in the first version of the anime, where our five girls are childish practically most of the time. Introducing the Outer Senshi to the story helped to give the female cast more balance.

Also, this pair tend to keep themselves in their private little world. It might look at first sight as a protective shield, away from the fame of their civilian lives. But once we discovered they also were Sailor Senshi, we found out that what they ultimately wanted is to protect their Princess (Sailor Moon) without hurting her or the others. In episode 98, Haruka even states that they made the promise of fulfilling their mission as Sailor Senshi even if one of them dies. These girls take matters on their own hands!
