Sailor Mercury

Ami's most emphasized character trait is that she is extremely intelligent—in the anime and manga she is rumored by other characters to have an IQ of three hundred, while in the stage musicals this is stated as a fact.[3] She is adept at English in both the musicals and the anime, and in the live action it was clearly, although briefly, demonstrated by the actress portraying her (actress Chisaki Hama was speaking to an English speaking character as her character was visiting the United States as a medical intern).[4] Her peers view her with a mixture of awe and distaste, misinterpreting her inherent shyness as snobbery, and so she tends to have a difficult time making new friends.[5] Ami is depicted as kind, sweet, gentle, and loyal, as well as slightly insecure. She also dislikes the fights of Sailor Moon and Sailor Mars.[6] Anne Allison describes her as "a smart girl who needs to relax", calling her "conscientious" and "studious", "everything Usagi is not".[7] Early on in the story, she relies heavily on the approval of her mother, teachers, and friends, but as the series progresses she becomes stronger and more confident in herself. She is generally the most sensible of the main characters, and is often the only one embarrassed when the group has a dull-witted moment. As the story begins, she attends Azabu Jūban Junior High along with Usagi Tsukino and, later, Makoto Kino.

Throughout the series, much of Ami's free time is spent studying. She loves to read, and dreams aloud of one day being a doctor like her mother and becomes one in both Parallel Sailor Moon and the live action series. In the musicals, Ami's dream of being a doctor and leaving Japan to study abroad is a recurring theme.[8] The first part of the song Dream Yume wa Ookiku (ドリーム　夢は大きく, lit. Dream - Dreams are Huge) shows Ami's conflict between studying abroad and growing up or being with everyone else and staying a young girl. She faces a similar dilemma in the anime, but very directly; given the opportunity to study in Germany, she gets as far as the airport before deciding to stay in Japan and fight evil alongside her friends.[9][10]

Ami has a great appreciation for art as well as science, and, contrary to the usual depiction of a bookworm, enjoys pop culture and romance novels (though she is usually embarrassed to admit it). In both the anime and the manga, Ami's diligence in her studies becomes a running gag; she often comically scolds Usagi and the others for not doing their homework, and she can become obsessive about being the best student. Her character has been interpreted as a political commentary on the education system of Japan.[11] She sometimes displays attraction to boys her age, and other times aversion to the idea. Love letters are listed as the one thing she has most trouble with,[12] and when she later receives one, it gives her a rash.[2] In the anime, a classmate named Ryo Urawa learns her identity and expresses attraction to her, but this is never resolved, as he disappears after just two appearances in the first series.[13]

Besides reading, Ami is shown playing chess and swimming in order to relax.[12] As the team scholar, computers are listed her strong point; she even belongs to the club at school.[14] She loves all her classes, especially mathematics. Her favorite foods are given as sandwiches and anmitsu, with her least favorite being yellowtail.[12] Other loves include cats,[15] the colors aquamarine and blue, the flower Water Lily, and the gemstone sapphire.

Ami is one of the few girls in the series whose family situation is explicitly mentioned in the anime. Her parents are divorced, and she lives with her mother, a busy doctor who is not home very often, named Saeko in the live-action series.[16] They look very similar, and Ami admires her mother and longs to live up to her example.[11] Besides her workaholic tendencies, Dr. Mizuno is portrayed as a good person who openly resents not having more time to spend with her daughter. Ami's father is never named, but is stated in the manga and anime to be a painter. The manga says that he never visits them, having decided one day not to come home from the forest where he was relaxing and painting, but he sends her postcards on her birthday. Thinking about this, Ami sometimes resents her parents' selfishness in separating,[17] partly because divorce in Japan is taboo.[18] However, in the anime Ami seems to appreciate her father and seems to share some of his artistic traits, at one point even composing matching lyrics for a tune that had none.[19] In the manga, Ami's mother is revealed to be fairly rich, as they live in a condominium.[20] Ami is shown testing the strength of a sword that the Sailor Soldiers received on the Moon by using it to chip a diamond ring. (Classically, a diamond is the hardest mineral.) When the girls panic, she calms them by saying that her mother has many more.[20] In the live-action series, Ami is especially shy and usually wears glasses while in public, even though she does not need them.[21] At her middle school, she has no friends before meeting Usagi and always eats lunch alone on the roof so she can study.[22] Usagi seems to be the only one to realize that Ami is merely shy, not truly standoffish, and in befriending her gradually helps Ami to learn that she is more than just a bookworm. By Act 34, when Ami's mother attempts to transfer her to another school because she thinks Ami's friends are bad influences, Ami rebels, avoiding the admission interview and spending the night at the Sailor Guardians' hideout with Rei Hino. Later she tells her mother that what she's doing in her life right now is more important than studying, and her mother understands.[23]

Ami is a kind and gentle girl who dislikes quarrels and abhors harming innocent people. These traits are even cited in the title of an anime episode, "Believe in Love! Ami, a Kind Hearted Soldier", where she persuaded Sailor Uranus and Sailor Neptune not to kill Hotaru. Like her comrades, her loyalty to Sailor Moon is unwavering, and she would sacrifice her life for her princess if necessary.

As a character with different incarnations, special abilities, powers, transformations, and ageless extended longevity; an extremely long lifetime virtually spanned between the Silver Millennium era and the 30th century, Ami gains multiple aspects and aliases as the series progresses.

Sailor Mercury using Mercury Aqua Mist in Sailor Moon Crystal.

In the manga, Ami can dowse without any aids.[35] Otherwise, she is not shown using any special powers in her civilian form, and may not be able to.[36] She must first transform into a Sailor Guardian by raising a special device (pen, bracelet, wand, or crystal) into the air and shouting a special phrase, originally "Mercury Power, Make-up!"[37] As she becomes more powerful and obtains new transformation devices, this phrase changes to evoke Mercury Star, Planet, or Crystal Power.[38]

Sailor Mercury has the power to create and manipulate water.[39] For the entire first story arc, she uses her water-manipulating capabilities only to create solid and dense clouds of mist and fog, chilling and blinding the enemy while her allies prepare more direct attacks. In the manga she usually does this without speaking, while in the anime it is given the name Shabon Spray.[40] In the updated renewal manga, this power is renamed Mercury Aqua Mist to match the live-action series and the second anime series, in which she has an offensive beam attack by that name, capable of destroying weaker enemies. She uses a total of five attacks in this series, most of which are variations on the first.[41]

Sailor Mercury's first major offensive attack is Shine Aqua Illusion, introduced in the second story arc, which can be used as a projectile, to freeze the enemy in solid ice, or to create a defensive barrier out of solid ice.[42] Aside from variations on her other powers (mostly improving their strength with the addition of "Freezing" or "Snow"), her next named attack is Mercury Aqua Mirage, used during the third arc of the manga and again in the special side-story "Ami's First Love" (manga and anime) and she also uses this attack in second anime series. Her final and greatest strength and power comes in the fourth story arc, when she takes on her second Sailor Soldier form (Super Sailor Mercury in the anime). At this stage she acquires a special weapon, the Mercury Harp,[17] and with it Mercury Aqua Rhapsody, which is her primary attack for the duration of the story. In the anime Mercury gains the harp deep within her subconscious. The manga took a different approach with the Mercury Harp making it more of an item rather than a harp formed due to the attack. Furthermore, Sailor Mercury gained the harp through her power guardian. In the manga the Mercury Harp, as well as the other Sailor Soldiers' weapons have their own "wills" and can even speak and give input.

In addition to her own powers, Sailor Mercury has more non-magical items than any other Sailor Soldier. Early on in the series she makes frequent use of an extremely powerful "Micro-miniature Super Computer"[43] that enables her to make special calculations, scan her surroundings, track the movements of allies as well as foes, and determine her enemies' weak points. The computer works in sync with her Mercury Goggles,[44] which analyze the area around her and display information in front of her eyes and on the Computer. The visor may be a hologram of some sort; it materializes across her face when she touches her earring. The manga sometimes shows her wearing a small microphone connected to her earring, which she uses to communicate with Luna at the Sailor Soldiers' hideout during the manga's first arc. All of these devices gradually fall out of use as the series progresses. In the live-action series, like most of the other Sailor Guardians, she receives a tambourine-like weapon called the Sailor Star Tambo.[45] She is one of two Sailor Guardians to use it for a named attack (Mercury Aqua Storm), and later can transform it into a sword. She also creates swords out of water, both as Sailor Mercury and as Dark Mercury.

In the manga, the Mercury Crystal and Mercury Harp are among her most significant magical possessions. The former is her Sailor Crystal and the source of all of her power, which becomes especially important in the fifth story arc. The harp's form is actually that of a lyre, a stringed instrument smaller than a harp, which according to Roman myth was invented by the god Mercury.

Noriko Sakai, circa. 2000 - Takeuchi describes Ami as looking like Noriko Sakai.

Ami was not included in the original proposal for a hypothetical Codename: Sailor V anime, which instead featured Minako's very similar-looking best friend from that series, Hikaru Sorano.[46] She was present, however, by the time the concept was expanded to center on Sailor Moon.

Creator Naoko Takeuchi designed Ami as the "team brain",[1] giving her genius-level intelligence to create the impression that she was not quite human—in fact, the character was originally intended to be a cyborg with an accelerator. One possible storyline involved her losing an arm or being injured in some other way and dying from it, but Takeuchi's editor objected, so Ami became a fully human character.[47]

Sailor Mercury's original costume design, like the others', was fully unique. It featured full-length sleeves, pink ribbons, shoulder guards, green accents, buttons on the stomach, and high-tech goggles. Later, Takeuchi was surprised by these sketches and stated that she did not remember drawing them.[48] She also describes Ami as looking like Noriko Sakai,[1] a J-pop idol of the early 1990s, and in Ami's original debut, Usagi thinks to herself that Ami resembles Miss Rain, a character from another Takeuchi series. This reference was removed in the 2003 renewal manga.[49]

The kanji in Ami's last name translate as "water" (水, mizu) and "field" or "civilian" (野, no); and her first name translates as "Asia" or "second" (亜, a) and "beauty" (美, mi). It is structured as a pun, as the syllable "no" indicates a possessive, so that her name can also be understood as "Beauty of Water." It is frequently mistranslated as "Friend of Water" because of the French word ami, which is included in some Japanese dictionaries.[50]

The official Sailor Moon character popularity polls listed Ami Mizuno and Sailor Mercury as separate entities. In 1992, readers ranked them at seventh and fourth respectively, out of thirty eight choices.[57] One year later, now with fifty choices, Ami was the eighth most popular while Mercury was ninth.[58] In 1994, with fifty one choices, Ami was the fifteenth most popular character, and Mercury was sixteenth.[59] In early 1996, with fifty one choices, Ami was again the fifteenth most popular character, and Mercury was the nineteenth.[60] Ami was the most popular female character in Animage's May 1993 poll, and an episode featuring her, "Love for Ami?! A Boy Who Can Predict the Future", was the eleventh favorite episode.[61] The following year she came second behind Belldandy,[62] and in 1995 she came fifth. In 1995, an episode featuring Ami, "The Labyrinth of Water! Ami the Targeted", was the ninth favorite episode.[63] In 1996, after the debut of Neon Genesis Evangelion, she came sixteenth,[64] and in 1997 she came twentieth.[65]

A five-book series was published, one book on each of the Sailor Soldiers and Sailor Moon. Ami's was released in 1996.[66] This book was later translated into English by Mixx.[67] The episode where Sailor Mercury gained her powers was novelised by Mixx.[68]

She was popular with the male audience of Pretty Soldier Sailor Moon due to her computer use and skills.[69]
