# Mobile Suit Gundam: The Witch from Mercury

Mobile Suit Gundam: The Witch from Mercury (Japanese: 機動戦士ガンダム 水星の魔女, Hepburn: Kidō Senshi Gandamu: Suisei no Majo) is a Japanese mecha anime television series and the fifteenth mainline entry in Sunrise's long-running Gundam franchise. The series is directed by both Hiroshi Kobayashi and Ryō Andō and written by Ichirō Ōkouchi, and aired from October 2022 to July 2023.
Set in a world where numerous companies have advanced into space and constitute a huge economic zone, the story concerns the Mobile Suits known as "GUND-ARMS" ("Gundams" for short), weapons that were developed out of diverted health technology "GUND" which compensates for physical disabilities caused by living in space.
The Witch from Mercury marks the first mainline Gundam series to air during Japan's Reiwa era, the first mainline production in seven years since Mobile Suit Gundam: Iron-Blooded Orphans, and the first TV series in the franchise to feature a female and LGBTQ protagonist. The anime revolves around capitalism and political corruption, stylistically inspired by Shakespeare's The Tempest with elements from witch trials, which inspires the titular Gundam technology.

## Story
### Setting

The series is set in the new calendar system dubbed the Ad Stella (AS). In this timeline, humanity has advanced into space yet a conflict occurred that caused a split between the inhabitants of space colonies, also called "Spacians" and the Earth-born "Earthians", with a vast economic inequality between the two. These conflicts revolved around the material, Permet, which was mined because of its information-linking properties. Various technologies have been developed by mixing Permet with other materials or propellants for control purposes, including Mobile Suit development. Several megacorporations are established in this timeline which all focus on the development of technology for Spacians but also caused the social and political divide between them and the Earthians.

### Plot

In the year Ad Stella 101, researchers at the Vanadis Institute created "GUND", an advanced brain–computer interface that enabled the human nervous system to control artificial appendages and organs. The purpose of GUND was to enable humans to survive in the harsh environment of space. After receiving funding from mobile suit manufacturer Ochs Earth, the technology was developed into the "GUND Format" and employed for military uses, leading to the creation of "GUND-ARMS": mobile suits that use the GUND Format to increase the performance of their pilots. However, extensive use of GUND-ARMS resulted in pilots being crippled or even killed.
In response, the Mobile Suit Development Council, led by the top mobile suit development companies, ordered an entire permanent ban on the GUND Format and all its applications. Council member Delling Rembran, president of the Benerit Group, deployed the special forces team Dominicus to destroy the Vanadis research facility Fólkvangr, killing everyone aboard to erase all traces of the technology. Only two people survived: mobile suit test pilot Elnora Samaya and her four-year-old daughter Ericht Samaya. In the aftermath, those responsible for the development of the GUND Format were ostracized, and because the team was primarily composed of women, they became known as "witches".
In Ad Stella 122, 21 years after the Vanadis incident, Suletta Mercury transfers from Mercury to the Asticassia School of Technology, an academic institute run by the megacorporation Benerit Group. Upon arrival, she encounters a girl escaping the institute, Miorine Rembran, who wants to escape from the control of Rembran her father. Miorine is engaged to be married to the highest scoring duellist in a mobile suit - currently Guel Jeturk.
As their paths cross in the academy with different ambitions and goals, Suletta will have to prove her worth as a pilot as she steps into the academy alongside the Gundam Aerial, a mobile suit built with forbidden GUND Format technology.

## Production and release

The series was first revealed by Sunrise at the 2nd Gundam Conference held on September 15, 2021, under Bandai Namco Group's "Gundam Project". It is the first mainline Gundam TV series in seven years, following 2015–2017's Iron Blooded Orphans. Bandai Namco Group cooperated with external partners called "G-PARTNER" to bring young people in their teens worldwide. A teaser was released on March 29, 2022, revealing the main mecha and a female character alongside a prologue episode that premiered on July 14, 2022. On June 17, Sunrise revealed the series's main plot, characters, staff, and a confirmed air date alongside an overview for the Prologue Episode. The staff working in the series were composed by director Hiroshi Kobayashi, with Ryō Andō serving as co-director; Ichirō Ōkouchi overseeing and writing scripts; mogmo designing the characters; Marie Tagashira, Shuri Toida, and Hirotoshi Takaya adapting mogmo's designs for animation; JNTHED, Kanetake Ebikawa, Wataru Inada, Ippei Gyōbu, Kenji Teraoka, and Takayuki Yanase designing the mechs; Shinya Kusumegi, Kanta Suzuki, and Seizei Maeda animating the mechs. Producer Naohiro Ogata mentioned in an online press conference that the story will be set in an academy that it will feature the first female main protagonist in the mainline series, and that he will create a work that is conscious of the increase in new fans. On July 14, information regarding the Prologue episode was revealed at "Gundam Next Future - Link the Universe-", which was the first public event for "Prologue.
The series' story and theme were developed by Ōkouchi, Kobayashi, and Andō. They based it on the tech companies competing for profits and control in the industry alongside elements from William Shakespeare's play The Tempest and the witch trials in the early modern period, reflecting the theme surrounding the GUND-Format technology and the people involved in its research, comparing it to a "curse" by the normal people. Ōkouchi decided to use a school sector to broaden the appeal but also made sure to feature "dark turning points and disturbing stories" that are emblematic of the Gundam series. Notably, The Witch from Mercury is the first Gundam TV series to feature a female protagonist and fourth in the franchise overall (after École du Ciel, SEED C.E. 73: Stargazer, and Twilight AXIS).

## Reception
### Critical response

The Witch from Mercury has been praised by critics for its writing, characters, animation, voice acting, dark drama, yuri elements, and its unique take on the classic Gundam formula. IGN gave the first season of the series a rave review, giving it a 9/10, praising the show's drama and striking imagery. Polygon also gave the show's first season a glowing reviewing, claiming the series is becoming the "ultimate Gundam show" and is finally an anime in the prestige franchise that anyone could enjoy. Kim Morrissy from Anime News Network has also praised the series, citing the show has good emotional moments. Harry Nugraha from Game Rant was less impressed with the first season, finding the school life drama to be "disappointing". However, Nugraha thought the show featured some "thrilling combat scenes" and felt the series was picking up steam in the last few episodes of the season. Vulture listed the first season as the third best anime of 2022. Following the finale of the second season, Tsunehiro Uno of PLANETS criticized the series for failing to adequately engage with the first season's issues of mediocre direction and breaking out of comfort zones, noting that the theme of conflict was ultimately relegated to being an Easter egg of the school life setting.
Mamiko Noto's portrayal of Prospera has received acclaim, with many lauding her theatrical performance and the complexity of her character. Gizmodo positively compared Prospera to the Gundam franchise's iconic villain Char Aznable, referencing how both characters wear masks and the duality of their personalities. Christopher Farris from Anime News Network also raved about the character, applauding her effectiveness as a villain and found her storyline to be "gripping".
The English dub received controversy due to the decision to have Suletta Mercury be voiced by a white voice actor Jill Harris. Suletta Mercury is implied to have Middle Eastern or North African heritage and her father's name Nadim Samaya has Arabic, Hebrew, and Indian origins.

### Reaction to the Season one finale

The end of the first season of the Witch from Mercury featured Suletta piloting the Gundam Aerial to smash a terrorist violently. Many viewers and commentators were caught off guard by the sudden act of violence, especially the imagery of Suletta's blood-stained hands and Miorine's horrified reaction. The finale was compared to a major twist from Code Geass, another anime project worked by Ichirō Ōkouchi. Both the Witch from Mercury and Code Geass trended on social media as fans reacted to the gruesome scene in Gundam. Japan's Broadcasting Ethics & Program Improvement Organization shared complaints from parents about the violent nature of the episode, with many finding it to be too graphic to show at the 5:00 PM timeslot when children are still up to watch it.

### Criticism on working conditions for Season two finale

The Witch from Mercury garnered some criticism after the airing of Season Two, Episode 24, when it was revealed that over 90 key animators worked on the series' final episode. The end credits of said episode listed 94 key animators who worked on the series finale, an unusually high amount for one episode of a half-hour animated TV series. One of the credited character designers, Marie Tagashira, praised her colleagues for completing a difficult and impressive work but excluded an unnamed few from her celebratory tweet. Fans and journalists took this as a hint animators involved in the creation of the show suffered from mismanagement that was forced to be addressed via human-wave tactics and overtime.

### Removed mention of same-sex marriage

In July 26, 2023, an interview with Witch from Mercury's voice cast in the September 2023 issue of Gundam Ace magazine included a quote from Kana Ichinose in which she referenced Suletta and Miorine's marriage. Miorine was also directly referenced as Suletta's wife by the official English-language Gundam Twitter account on the day of the finale. Following the release of the magazine interview, the hashtag スレミオ結婚 (SuleMio Marriage) trended in Japan.
Days later, however, the digital version of the Gundam Ace interview was edited to remove the direct reference to marriage, causing an immediate backlash from Japanese and Western fans of the show, who claimed the characters' "undisputed" status as a married couple was being deliberately censored.
On July 30, a statement was released by Kadokawa in which they claimed the discrepancy was a "proofreading mistake" and that the marriage reference was based on "editorial speculation". An accompanying statement was released on the official Witch from Mercury website in which these claims were repeated, in addition to implying the events of the series are open to interpretation by viewers, leading to angry or confused responses from fans and general viewers who pointed out Suletta and Miorine's marriage was objectively confirmed both in the anime's final scene and by the characters' voice actors in an audio commentary for the final episode or official final stream after that, and as such no room for "interpretation" exists.
The wedding itself was not depicted on-screen, but the characters are shown wearing rings in the final scene of the series, and Suletta's sister Ericht refers to herself as Miorine's sister-in-law. The September 2023 issues of the Animage and Animedia magazines published on August 9 provided Mamiko Noto and Lynn's interpretations of the scene as Ericht behaving like an in-law.
Five months after the initial magazine controversy, Witch from Mercury's final Blu-ray volume was released, including an interview with Hiroshi Kobayashi, series director and storyboard artist for the series finale, confirming Suletta and Miorine are indeed married in the story's final scene. Following this confirmation, the hashtag スレミオ結婚 (SuleMio Marriage) once again trended in Japan.
