Every arc of Naoko Takeuchi Sailor Moon presents at least a pair of twinswhether good or bad, but his presence is never a specific focal point of the plot. Sailor Moon is obviously known for incorporating symbolism, Greco-Roman mythology, and astrology, but Takeuchi’s degree in Chemistry from Kyoritsu College of Pharmacy and his scientific background also shine with allusions to technical jargon, minerals, and real elements. These elements don’t feel forced, and most Sailor Moonthe audience may ignore the hidden meanings, but they are there and serve a purpose nonetheless.
Sailor MoonSince its manga debut in 1991, it has maintained global popularity, leading to a widely loved anime adaptation in 1992, a film trilogy, and the 2014 film. Sailor Moon Crystala reboot more in line with the manga. The series’ enduring appeal stems, in part, from Takeuchi’s masterful layering of ancient lore within a modern myth, adding new depths to each character and arc. From monsters of the week to powerful Guardians in the far reaches of the universe like Sailors Chi and Phi, the twins are always memorable and impactful to the story.
The origins of the Sailor Moon twins trope are rooted in mythology
Even the smallest details have meaning in the series
Takeuchi’s fascination with Greco-Roman mythology is at the heart of Sailor Moonbased on the tale of Endymion and Selene, the moon goddess. Castor and Pollux are among his most direct adaptations of twins from mythology, appearing as antagonists in episode 21 of the ’90s anime adaptation, “Protect the Children’s Dreams: Friendship Through Anime.” Castor and Pollux, twins from different fathers, are immortalized as the brightest stars in the constellation Gemini after their deaths. His ability to mimic the attacks of Mercury and Mars causes problems for the Guardians at a time when there were only three of them.
In the final story arc, covered in the 2023 film Cosmo from Sailor MoonUsagi faces the twin sisters Mnemosyne and Lethe, guardians of two rivers that flank the villain’s palace. These characters evoke the Greco-Roman goddess of memory and her counterpart, Lethe, the river of the Underworld that causes forgetfulness. Here, Lethe erases Usagi’s memory, casting doubt on her path to defeating Sailor Galaxia, while her twin sister Mnemosyne restores Usagi’s confidence and sense of purpose. Takeuchi’s portrayal aligns with ancient mythology, but she cleverly uses the twins to create internal conflicts for Usagi, symbolizing the struggle between clarity and doubt.
Two are more powerful than one
Having a twin represents an increase in power in Sailor Moon
Gemini in Sailor Moon are often associated with strength amplified through sibling bonds. While Sailor Guardians typically work as a team to weaken their enemies and create openings for Sailor Moon’s finishing moves, the twin enemies present a unique challenge. The twin brothers of the Dark Moon Clan, Chiral and Achiral, and Ptilol and Cyprine of the Witches 5 operate by separating themselves to confuse the Guardians before unleashing powerful combined attacks. The brothers’ names also come from an organic chemistry term, “chirality”, and the sisters are named after rare minerals.
A notable exception to the twin villain trend is Sailor Mars’ loyal servants, Phobos and Deimos. These twin Guardians leave their home planet of Koronis to serve Princess Mars. Named after the moons of Mars – Phobos and Deimos, in myth the children of Aphrodite and Ares – they transform into ravens that guard Rei’s family sanctuary. Phobos and Deimos provide spiritual and emotional support to Sailor Mars as she balances the Sailor Guardian duties and her family’s sanctuary. Their loyalty and protective nature exemplify the positive potential of twin bonds.
Twins are a symbol of bad luck in Japanese culture
Bad luck seems to follow the guardian sailors
In Japanese culture, twins have historically been seen as symbols of bad luck, often associated with misfortune or imbalance. This layer of superstition adds an intriguing cultural tone to the Sailor Moontwin characters, especially those aligned with the villains. While international audiences may not notice this nuance, it highlights the idea that the twins, in their unpredictability, could disrupt the stability of the Sailor Guardians and bring chaos to their world. In Sailor Moon EternalTwin circus performers, Xenomite and Zeolite, terrorize Sailor Venus, destroying her self-confidence and causing her to fall to her death. Fortunately, she is saved by Artemis at the last second.
The theme of twins in Sailor Moon it can be overlooked because it is subtly woven into the story rather than making it a central plot point. The series’ layers of Greco-Roman mythology, Japanese cultural symbolism, and twin dynamics add depth but remain accessible for viewers who may not catch all the references. However, these recurring twin characters contribute to the thematic richness of Sailor Moon, making it clear why Takeuchi’s series is still a cultural juggernaut.
