Sailor Mars

Sailor Mars is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sailor Mars rather than just read about it. In short: Rei Hino (Japanese: 火野 レイ, Hepburn: Hino Rei; renamed Raye Hino in some English adaptations), better known as Sailor Mars (Japanese: セーラーマーズ, Hepburn: Sērā Māzu), is a fictional character in the Sailor Moon manga series written and illustrated by Naoko Takeuchi.

Key takeaways

  • Sailor Mars belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sailor Mars to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sailor Mars from memory before moving on to harder problems.

Reference excerpt

Rei Hino (Japanese: 火野 レイ, Hepburn: Hino Rei; renamed Raye Hino in some English adaptations), better known as Sailor Mars (Japanese: セーラーマーズ, Hepburn: Sērā Māzu), is a fictional character in the Sailor Moon manga series written and illustrated by Naoko Takeuchi. In the series, Rei is her sailor form's alternative human identity as part of the Sailor Guardians, female supernatural fighters who protect the Solar System from evil. Rei is the second Sailor Guardian to be discovered by Usagi, following after Ami Mizuno. She possesses powers associated with fire, the Ofuda charm, and psychic clairvoyance. Aside from the main body of the Sailor Moon series, Rei is featured in two different manga short stories. The first, Casablanca Memories, is entirely about her and her past; the second, Rei and Minako's Girls School Battle, is shared with Minako Aino. A number of image songs mentioning her character have been released as well, including the contents of three different CD singles. Takeuchi based Rei on her own personal experience as a miko. Originally designed with her own unique outfit, when Takeuchi decided to give all of the Guardians identical outfits, Rei's high heels were the only aspect that was carried over. A cold and aloof character in the manga, her personality was drastically changed in the anime adaptation at the behest of Kunihiko Ikuhara, where she became stubborn.

Profile Rei first appears as a miko at the Hikawa Shrine, and is shown to have an affinity with two crows who live there. It is revealed in the manga that as a child, the crows "told" her that their names are Phobos and Deimos (the same as Mars' two moons). In the manga, she is portrayed as imperial, ancient, conservative, old-fashioned, traditional, serious, disciplined, and practical, having contempt for men and disliking modern romantic relationships. In the anime adaptation, Rei is a disciplined and practical person. She is also greatly interested in pop culture, and she excels at music—composing songs for a school festival. Rei and Usagi Tsukino have a very tempestuous relationship, and argue frequently. Though these arguments are usually petty, early in the series Rei attempts to usurp Usagi as the leader of Sailor Guardians. Even though Rei does become more loyal to Usagi, with slightly calmer emotions in the later seasons, she still remains somewhat more of a typical teenager than her manga counterpart. In the anime, Rei also tends to engage in long periods of antagonizing Usagi (who returns the same reaction), as a running gag in their arguments. Rei goes to a different school from the other girls, namely T*A Private Girls School, a Catholic institution run by nuns. She herself is a practitioner of Shinto, living and working at Hikawa Shrine with her grandfather, its head priest. Her mother died when Rei was very young; her father is a famous politician who cares more about his job than about her (though in the live-action version he still tries to be involved in her life), and who only visits Rei on her birthday. She carries a certain amount of dislike towards him, especially in the live-action series, in which the character of her grandfather does not appear.

Worked examples

Example 1 — a first encounter with Sailor Mars

Start with the simplest possible case. Write down what Sailor Mars claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sailor Mars before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sailor Mars ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sailor Mars

In research
Sailor Mars appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sailor Mars in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sailor Mars is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anime and manga characters introduced in 1992, Fictional Martians, Fictional archers, so understanding it makes those chapters shorter.
In everyday life
Look for Sailor Mars outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
