Aria (manga)

Aria (stylized as ARIA) is a Japanese manga series written and illustrated by Kozue Amano. The series was originally titled Aqua (stylized as AQUA) when it was published in Enix's Monthly Stencil magazine in 2001, and retitled when it was transferred to Mag Garden's Comic Blade, where it continued serialization from 2002 to 2008. Aqua was collected in two tankōbon volumes, and Aria was collected in twelve volumes.

Hal Film Maker has adapted the manga into several anime television series. A first season was broadcast in 2005, a second season in 2006, an OVA released September 2007, and a third season in 2008 that ended around the same time as the manga serialization. An OVA, titled Aria the Avvenire, was released in the anime series' 10th anniversary Blu-ray box sets between December 2015 and June 2016. A film to celebrate the 15th anniversary of the anime series titled Aria the Crepuscolo premiered on 5 March 2021. A second anime film titled Aria the Benedizione premiered on 3 December 2021.

ADV Manga released English translations of the first three volumes of Aria in 2004 before dropping the license. Tokyopop then acquired the English-language rights to Aqua as well as Aria. Tokyopop released the two volumes of Aqua in October 2007 and February 2008 and six volumes of Aria between January 2008 and December 2010. The anime is licensed in North America by The Right Stuf International, which released all three seasons in box sets under its Nozomi Entertainment imprint between 30 September 2008 and 2 March 2010.

The series is set in the 24th century on a terraformed Mars, now named Aqua, and follows a young woman named Akari Mizunashi as she trains as an apprentice gondolier (known as Undines). The series has been praised for its calm pacing, optimistic worldview, beautiful art, and for the anime, the quality of the soundtrack.

Story
Aqua and Aria take place in the early 24th century, starting in 2301 AD, in the city of Neo-Venezia (ネオ・ヴェネツィア Neo Venetsia, literally "New Venice") on the planet Aqua (アクア Akua, formerly Mars, sometimes stylized as in the manga with the base text for "Mars" serving as a gloss), which was renamed after being terraformed into a habitable planet covered in oceans around 150 years beforehand. Neo-Venezia, based on Venice in both architecture and atmosphere, is a harbor city of narrow canals instead of streets, traveled by unmotorized gondolas.

At the start of Aqua, a young woman named Akari arrives from Manhome [sic] (マンホーム Manhōmu, formerly Earth, sometimes stylized as  with the base text for "Earth" serving as a gloss) to become a trainee gondolier with Aria Company, one of the three most prestigious water-guide companies in the city. Her dream is to become an Undine, a gondolier who acts as a tour guide (see Terms below). As she trains, Akari befriends her mentor Alicia, trainees and seniors from rival companies—Aika, Alice, Akira, and Athena—and others in Neo-Venezia. Aqua covers Akari's arrival on Aqua and her early training as a Pair or apprentice. Aria continues her training as a Single, or journeyman, culminating in the graduation of Akari, Aika, and Alice as full Prima Undines.

Each chapter is a slice of life episode of Akari's exploration of the worlds of gondoliers, Neo-Venezia, and Aqua itself. Amano frequently uses several pages of lush art to depict an environment, showing the wonder of both everyday activities as well as one-of-a-kind events. It has been described by reviewers as very similar in tone and effect to Yokohama Kaidashi Kikō.

Aria Company
Aria Company is a small water-guide company that starts with only two employees. Its uniforms are lined with blue, and its president (and namesake) is Aria Pokoteng.
 * Mizunashi Akari (水無 灯里)
 * A native of Japan on Manhome (Earth) who immigrates to Aqua when she is 15 to become an Undine. While not as skillful at rowing a gondola as Alice nor as familiar with the history of her adopted city as Aika, Akari makes friends quickly and easily converses with customers and other strangers. She is depicted as optimistic and cheerful, finding enjoyment in things or events that others think humdrum and mundane, for which Aika and Alice call her "mysterious"; in the anime, Aika and Alice separately comment that Akari seems to attract mysterious phenomena to her. Akari often says Hohe or Hahi, which is her short version of "wow". When Akari used gondola simulations on Manhome, she accidentally learned how to row backwards and has to relearn the proper method when she starts at Aria Company; however, as Alicia puts it, "When rowing backward, Akari-chan is unrivaled!"
 * Most chapters of the manga and episodes of the anime are framed with narration taken from e-mails written by Akari. In the anime, the recipient is a young girl named Ai, a customer in the first episode who becomes Akari's pen pal, but in the manga the recipient is someone she does not name and is referred to as zenryaku but has never seen.
 * At the start of Aqua, Akari arrives on Aqua as a new Pair (apprentice) at Aria Company. In chapter 5 of Aqua, when Aika is promoted to Single (journeyman), Alicia tests and promotes Akari as well. Later, in chapter 58 of Aria and episode 12 of Aria the Origination, after Aika is promoted to Prima (full Undine), Alicia gives Akari the test for Prima. When Akari passes, she is given the title "Aquamarine" (遙かなる蒼).

When Akari passes, she is given the title "Aquamarine" (遙かなる蒼).


 * Arishia Furōrensu (アリシア·フローレンス)
 * The only other Undine with Aria Company, Alicia is one of the Three Water Fairies of Neo-Venezia, known by the title "Snow White" (白き妖精). At the start of the series, she is 19 years old and the most popular Undine in the city, noted especially for her graceful rowing style. She was promoted to Prima at 15, the youngest ever to do so. Like Akari, she is relaxed and easy-going, but she also likes to tease others, especially her childhood friend Akira. Her favorite phrase is "My, my" (ara ara; "Well Well") and she frequently giggles, to Akira's annoyance. According to Grandma Akino, she is an excellent Undine because of her ability to enjoy everything.
 * At the end of the series, Alicia announces her upcoming marriage and retirement to take an administrative position within the Gondola Association. She tells Akari she had put off her Prima exam because she had been planning to retire after that and did not want to leave her student and friend. According to issue No. 6 of Monthly Undine, after her retirement, "Snow White" is designated the 8th "honored appellation" by the Gondola Association, as an Undine who made great contributions to the industry.

 * Ametsuchi Akino (天地 秋乃) Guranma (グランマ)
 * A famous and long-serving Prima Undine, who started Aria Company with Aria Pokoteng after realizing she was missing too much of life as Himeya's top ace. She was Prima Undine for 30 years and mentor to Alicia, her last disciple, to whom she left the company on her retirement. She is highly respected by younger Undines, who call her "Grandma".

 * Aino Ai (愛野アイ)
 * A girl from Manhome. In the anime, she befriends Akari in episode 1 and becomes Akari's e-mail correspondent, while visiting Aqua whenever she can. In the manga, she first appears in chapter 60 as Aria Company's newest employee. In both versions, at the end of the series she becomes a Pair under Akari after Alicia's marriage and retirement. At some point before the start in the OVA Aria the Avvenire, she becomes a Single.

 * Anna (アンナ)
 * A retired Undine who trained under Grandma Akino, becoming a Prima before Alicia. She left Aria Company shortly after Alicia was promoted to Prima to marry a fisherman named Alberto. She has a son named Ahito, and lives with her family on Neo-Burano Island.

Himeya Company
Himeya Company is the oldest and currently second-ranking water-guide company in Neo-Venezia. It employs 80 Undines, with a uniform lined with red. Its president is Hime Granzchesta.
 * Aika S. Granzchesta (藍華·S·グランチェスタ)
 * The first friend Akari makes on Aqua, Aika is 16 when they meet. Aika is a Pair and then Single at Himeya Company. She is the only daughter and heir of Himeya Company's owners. However, she does not enjoy the distinction as she feels the company's employees fawn on her too much. Aika speaks bluntly and often responds to Akari's idealistic comments with "Embarrassing remarks are not allowed!" (恥ずかしいセリフ禁止!). Despite their contrasting personalities, she gets along well with Akari and Alice. However, she frequently squabbles with her mentor, Akira, whom she resembles. Aika considers herself reliable, especially compared to the distractible Akari and antisocial Alice, but both her friends call her a crybaby for her tendency to tear up when emotional. She is proud of her gondola skill as an Undine and can be very competitive about it. She also greatly admires Alicia and finds any excuse to visit Aria Company—and once tells Akari that if not for her family obligations, she would have joined Aria Company. Over the course of the series, Aika develops feelings for Al.
 * In chapter 58, Aika becomes a Prima, taking the title "Rosen Queen" (薔薇の女王). She takes charge of a newly opened Himeya branch office in preparation for taking on the whole company one day.

 * Akira E. Ferrari (晃·E·フェラーリ)
 * One of Neo-Venezia's Three Water Fairies and a native of Aqua. As a Prima Undine, Akira is called the "Crimson Rose" (真紅の薔薇) and is famed for her conversational skills. She has many admirers among her customers, especially her female ones, but she considers herself very feminine. In flashbacks, Akira is shown as very tomboyish when young, to the point of using a male pronoun for "I" (俺) (see gender differences in spoken Japanese) and being mistaken for a boy by Akatsuki. Akira is a mentor to Aika, who calls her the Demon Instructor for her strictness and loud, brusque personality. Akira is particularly harsh with Aika because she believes there is potential in her, and Aika admits that it is only due to Akira's strictness and honesty that she has become a good Undine.
 * Akira and Alicia are childhood friends, and their relationship mirrors Aika and Akari's. However, Alicia teases Akira far more than Akari does Aika. Akira still resents that Alicia became a Prima before her. Upon Alicia's retirement at the end of the series, Akira becomes the undisputed top Undine in Neo-Venezia.

 * Ayumi K. Jasmine (アユミ·K·ジャスミン)
 * Ayumi appears in the Origination series as a cheerful Single for Himeya Company, who often works as a traghetto rower with Atora and Anzu from Orange Planet. Unlike many Undines, Ayumi doesn't plan to become a Prima because she wants to specialize in the traghetto, which gets her involved with the city and its people as well as lets her make money.

Orange Planet
Orange Planet is the largest water-guide company in Neo-Venezia, employing 81 Undines (including 20 Primas). Its uniforms are lined with yellow, and its president is Maa.
 * Alice Carroll (アリス·キャロル)
 * Alice is a 14-year-old Undine for Orange Planet. She first appears (in volume 3 of Aria/episode 3 of Aria the Animation) as a standoffish, detached girl. Aika later describes her as anti-social and complains about her tendency to put on a grim face and speak in a quiet voice. Alice speaks in a deadpan manner, though she frequently uses dekkai (でっかい) as an intensifier. Although initially only a Pair, her rowing already surpasses both Aika and Akari's—for which skill Orange Planet scouted her despite her young age. Despite working for rival companies, Alice, Akari, and Aika often practice together, and Alice sincerely enjoys the others' company, though this does not stop her from telling them to be quiet when they argue. Because of her age and lower status, Aika often addresses her as "kōhai-chan" (後輩ちゃん). Through her friendship with Akari and Aika, Alice lightens up as the series progresses. However, she still struggles with her detachment.
 * For a long time, Alice was not confident in her singing skills until Athena advised her to enjoy what she sings and not worry about her performance. In volume 11 of Aria, after Alice graduates from middle school, she is promoted to Prima straight from Pair, the first Undine to do so, and is given the title "Orange Princess" (黄昏の姫君).

 * Athena Glory (アテナ·グローリィ)
 * One of Neo-Venezia's Three Water Fairies, known by the title "Siren" (天上の謳声) for her beautiful singing voice. She is Alice's mentor at Orange Planet. She is quiet most of the time and often appears to be an airhead who does not pay attention to her surroundings (in the anime, she is shown more than once forgetting to duck while rowing under a bridge), but she genuinely cares about Alice. Athena has a strange laugh that comes out sounding as though she is angry. She was a trainee Undine with Alicia and Akira. She joined them in joint practice sessions like Akari, Aika, and Alice do now. At the conclusion of the series, Athena semi-retires from being an Undine to debut as an opera singer.

Cats
Because blue-eyed cats are considered lucky on Aqua, all Undine companies have a blue-eyed cat as a mascot, who is given the title President. Cats on Aqua have been bred to be as intelligent as humans, though they cannot speak.
 * President Aria Pokoteng (アリア·ポコテン)
 * President and namesake of Aria Company, and an Aqua cat. Aria is large and fat, massing 10 kg. He is attracted to President Hime, who does not appear to reciprocate his sentiments; his pursuit of her is a common comic relief scene.

 * Cait Sith (ケット・シー)
 * A huge cat with mysterious powers, said to be Cat-sìth from Scottish folklore. He has been the king of the cat kingdom in Aqua for at least 100 years. In the anime, Alicia and Akari suggest that he is the spiritual guardian of Aqua. Jun'ichi Satō, the anime director, claimed that his interpretation is "a little different from the original manga's interpretation". It is hinted at various times throughout the manga as he secretly guides and protects Akari to the seven mysteries of Neo Venezia, and is ultimately revealed that he is Akari's pen pal and the final mystery.

Other characters

 * Akatsuki Izumo (出雲 暁)
 * Akari's first customer as a Single. He is a tall, impatient young man who calls Akari "Pigtails" or "Sideburns" (momiko) to tease her. He works as an apprentice Salamander, someone who helps maintain Aqua's climate in the floating buildings that are tethered overhead. Although drawn like a typical bishōnen, his constant scowl combined with a loose-fitting robe usually covers up his more "attractive" features, which he rarely displays. Akatsuki has an older brother who teases him to the point of rage.
 * Akatsuki is not on the ground often, so every visit to the surface is an adventure for him. He claims to be in love with Alicia, though Alicia and his older brother suggest that he is really attracted to Akari. In any case, every visit to Neo-Venezia, no matter his official reason, he spends most of his time with Akari.

 * Udo Ayanokoji the 51st (綾小路宇土51世)
 * More commonly known as "Woody". Woody is a Sylph who delivers packages and other goods to people in Neo-Venezia. He has a bad sense of direction and cannot navigate without a map. His physique is well-built, and he is usually seen wearing goggles. He was childhood friends with both Akatsuki and Al.

 * Albert "Al" Pitt (アルバート·ピット)
 * Al is a Gnome, a person who lives underground regulating Aqua's gravity so that it is the same as Manhome's. Gnomes rarely come to the surface except to shop. He looks younger than Akari and Aika, but he is actually three years older. His young appearance is due to the stronger gravity underground making him smaller.

 * Namihei Anno (庵野波平) Mr. Postman (郵便屋さん)
 * An elderly mailman in Neo-Venezia, called Mailman-san or Mr. Postman by Akari. He is the first person that Akari meets after arriving on Aqua. He is a kind man who is devoted to his work and his younger co-workers. Akari does not learn his name until near the end of the series when he hires her for a gondola ride after retiring from his job.

Terms
Several terms of the world of Aqua are derived from elemental mythology:


 * Undine: A gondolier acting as a refined tour guide for visitors to Neo-Venezia. All known Undines are young girls and women, except those of the gender-flip parallel world in the Special Navigation of volume 6.
 * Pair (ペア): An apprentice Undine who has just begun practicing sculling a gondola. A Pair is recognized by her pair of gloves, worn to protect her hands as she builds up calluses. When a Pair is promoted to Single, she removes one glove. This is translated by Nozomi and ADV as "Pair", and by Tokyopop as "apprentice".
 * Single (シングル): A journeyman Undine qualified to take customers only under supervision. So-called because she wears only one glove. Nozomi and ADV translate this as "Single," and by Tokyopop as "journeyman."
 * Prima (プリマ): A graduated Undine who is no longer a Single. Once an Undine becomes a Prima, they can take customers without supervision. This is translated by Nozomi and ADV as "Prima", and by Tokyopop as "full-fledged Undine".
 * Salamander: A person working at controlling the weather and adding heat to the atmosphere as part of terraforming Aqua. Salamanders live in floating islands tethered at high altitude.
 * Gnome: A person working underground to regulate the gravity of Aqua, so that it is as strong as Manhome (Earth). Because of their environment, most gnomes are short and have bad eyesight.
 * Sylph: A person who makes deliveries by air bike. Deliveries are done by air in Neo-Venezia because only unpowered watercraft such as gondolas are allowed in the smaller canals of the city.
 * Traghetto: A gondola designed to ferry several people across the Grand Canal. Because of its size and the number of passengers, the gondola is rowed by two Singles.
 * Three Water Fairies (水の三大妖精): Neo-Venezia's three most accomplished Undines at the time of the series: Alicia Florence, Akira E. Ferrari, and Athena Glory.
 * Seven Mysteries of Neo Venezia (ネオ・ヴェネツィアの七不思議): The seven mysteries of the city of Neo Venezia that very few people have ever gotten to witness. Akari is the only person to do so when the story takes place, thanks to personal guidance from Cait Sith. Those mysteries include the endless waterway hall, the Carnival Casanova, the mirage coffee shop, the galactic train that runs in the night sky, the legendary lady of San Michele Island, the (street) stone of misfortune, and Cait Sith himself.

Development
According to her original afterword to Aqua volume 2, Kozue Amano's goal in writing the series was to have readers find happiness in small things and to not focus on their failures. In another afterword, she stated that writing Aria has forced her to pay attention to the four seasons and that she hopes the series shows her appreciation for them. Amano developed a 24-month calendar system for Aqua, based on Mars's real orbital period of 668.6 local days (see Timekeeping on Mars), making every season 6 months long. Amano marked the passage of time and the seasons throughout the series through such means as Akari explicitly telling her correspondent the time of year and depicting seasonal observances such as fireworks at the end of summer (Aqua volume 2, Navigation 9 and Aria volume 4, Navigation 20), New Year's Eve (Aria volume 2, Navigation 9), or birthdays of characters (Aria volume 10, Navigation 46).

In the universe of Aqua and Aria, Neo-Venezia's builders modeled it after the city of Venice before its demise in the 21st century, including counterparts to such public landmarks as the Piazza San Marco and the Bridge of Sighs. In creating Neo-Venezia, Amano also based some of the fictional locations of the series on real Venetian locations. Examples include:
 * The Aria Company headquarters corresponds to the location of a vaporetto stop.
 * The Himeya Company headquarters is in the Danieli Hotel, located on the southern promenade, near Piazza San Marco.

Other locations on Aqua that Amano based on real places include the Japanese shrine visited in Aria volume 1, based on Fushimi Inari-taisha near Kyoto.

Adaptation as an anime
As part of the preparations for the first season of the anime adaptation, the production crew led by director Jun'ichi Satō made a trip to Venice for location research. As a result of filming the movements of gondoliers sculling, they had to redraw the animation of Undines rowing in the first episodes to make it realistic. Satō said that seeing a gondolier use his paddle to toss a bottle out of the water inspired the scene in episode 11 of Aria the Animation where Alicia does the same with a ball, which was not in the manga. As part of the production company's commitment to adapting the manga faithfully and gesture of consideration toward the voice actors, they provided the collected volumes of Aqua and Aria to date, rather than requiring them to purchase their own or giving stacks of photocopies.

According to Jun'ichi Satō, it was a struggle to fit the available material into the 13 episodes of the first season, which focused closely on Akari. The title of the second season, Aria the Natural, came about because he had 26 episodes to work with, letting him treat the story in a more "natural" manner, allowing the series to develop other characters more.

Choro Club and Takeshi Senoo composed 30 works of music for the first season of the anime and 15 for the second. Jun'ichi Satō and sound designer Yasuno Satō assigned Choro Club and Takeshi Senoo abstract themes instead of plot points, which was an unfamiliar method for the composers who did not have much experience working for anime shows. Takeshi Senoo and the three members of Choro Club make a cameo appearance as musicians in episode 23 of Aria the Natural. Jun'ichi Satō has commented that the lyrics for the songs "Barracole" and "Coccolo", sung by Eri Kawai as the voice of Athena Glory, were gibberish. The lyrics for the first two seasons' theme songs were also initially meant to be gibberish, but after reading the manga Eri Kawai decided to write Japanese lyrics: "I read the original manga and wrote the lyrics, using my image of Neo-Venezia as a starting point. Then did my best to match words that flowed with the melody." Kawai made demo recordings for Yui Makino as a guide for her performance of the theme songs. Takeshi Senoo has described "Smile Again", the second ending theme song of Aria the Natural, as a song about the end of summer, and envisioned it being sung by Erino Hazuki as Akari.

Manga
The manga was written and illustrated by Kozue Amano and has a complicated publishing history. Aqua was originally published by Enix in Monthly Stencil magazine from January to September of 2001 and collected in two tankōbon volumes. When the series moved to Mag Garden's Comic Blade magazine in February 2002, the title changed to Aria. Mag Garden later re-released the two volumes of Aqua with additional material and new covers. Serialization completed in February 2008. In all, the 70 serialized chapters of Aqua and Aria were collected in 14 tankōbon volumes, each volume containing five chapters covering a season of the year. Each volume is called a "voyage," and each chapter a "navigation."

In English, Aria (but not Aqua) was originally licensed by ADV Manga, who dropped the license after publishing three volumes. The North American license for Aqua and Aria was picked up by Tokyopop, which began releasing the series starting with the first volume of Aqua. The series has been licensed in France by Kami, in Germany by Tokyopop Germany,  in Italy by Star Comics,  in Indonesia by M&C Comics,  in South Korea by Bookbox, in Spain by Editorial Ivrea, in Taiwan by Tong Li Comics, and in Thailand by Bongkoch Comics.

Anime
Aqua and Aria were adapted by Hal Film Maker as a 54-episode anime television series comprising two seasons titled Aria the Animation and Aria the Natural, an original video animation (OVA) titled Aria the OVA: Arietta, and a third season titled Aria the Origination. The series was directed by Junichi Sato with character designs by Makoto Koga, and broadcast on the TV Tokyo Network between 2005 and 2008. All three seasons have been released on DVD in Japan. A special OVA series, Aria the Avvenire, received an event screening on 26 September 2015. It was animated by TYO Animations.

Reception
In Japan, new volumes of Aria routinely reached the best-seller list for manga, and had sold over 3 million copies as of July 2007, representing 11% of all manga volumes ever sold by its publisher to date. In 2009, this number increased to 4 million.

The English translation of the Aria manga was described by a reviewer at The Comics Journal as "quite conceivably the best comics series ever created for elementary-school girls," calling it "a masterpiece of storytelling and illustration, gorgeous to look at and a feast for the young imagination in its ability to present an inviting, fully realized world." Aqua and Aria together have been praised for their joyful calm, vividly depicted futuristic world, moments of magic, and sense of whimsy. Amano's artwork is praised for her crisp lines and details, especially in the backgrounds and landscapes. Amano has also been criticized for confusingly giving every character a name that begins with A, for letting some slice-of-life stories "drift too far out," and for making Akari's character too sweet and effusive.

In 2006, the anime of Aria was ranked in the top 100 animated television series of all time in a poll by TV Asahi. As of June 2007, the first two seasons of the anime adaptation had sold more than 300,000 DVDs.

The anime has been praised for its quiet atmosphere, beautiful visuals —especially the backgrounds and character designs —and exceptional soundtrack. Anime News Network described the first season as "a gorgeous future fantasy populated with loveable characters", where "each episode is a finely fashioned tone poem steeped in a love of the slow rhythms of everyday life and told with an elegant self-possession that places it light-years beyond the vulgar moralizing of most "uplifting" stories." IGN contrasted Aria with Maria-sama ga Miteru as another series where not much happens, noting that "Maria-sama ratchets up the tension level whenever possible, though, and never mind that all the drama revolves around something completely inconsequential. Aria, on the other hand, is calm and relaxed. It freely admits that the plot is not the point." Several reviewers cited the characters as key to the appeal of the series, though some criticized the characters as unrealistic; the voice acting of Erino Hazuki (Akari) and Junko Minagawa (Akira) were particularly praised. Several reviewers point out that the series does not fit all tastes, being a slow-paced drama with an optimistic outlook.
