SuleMio

SuleMio is the femslash ship between Suletta Mercury and Miorine Rembran from the Mobile Suit Gundam the Witch from Mercury fandom.

Prior Events
Due to their different circumstances, neither girl had friends growing up.

Suletta's mother, Lady Prospera, had Suletta enroll in Asticassia due to her knowing that her father, Delling Rembran, allowing whoever is the number one duelist to officially be engaged to his daughter, Miorine. She wishes to use her daughter as a means to accomplish her revenge against Delling who was apparently responsible for the destruction of the Vanadis Institute.

Prior to Suletta's arrival at Asticassia, Miorine was forced to be engaged to Guel Jeturk, heir of Jeturk Heave Machinery as well as the current Holder, and top of his class in the school-sanctioned duels. Due to Miorine's father being the head of Asticassia’s school board along combined with Delling's political powers in the Beneritt Group, Miorine was a constant target of others who wished to claim her as their bride, and Guel successfully managed to defeat more than twenty other challengers.

Due to Guel treating his relationship with Miorine as expendable and transactional over her status as heir to the power of the Beneritt group, more than anything romantic, Miorine resented Guel. This forced relationship are the reason why Miorine attempted to escape from Asticassia repeatedly.

Season One
Episode 01

Suletta and Miorine meet for the first time when Suletta is on her way to arrive at the Institute to attend school. She happens to notice someone floating in space. Suletta instinctively decides to rescue her only to find out that she inadvertently ruined Miorine's escape attempt to which Miorine demands Suletta take responsibility which Suletta agrees to in a confused manner.

When Suletta and Miorine meet for the first time, they crash into each other in space when Miorine discovers that Suletta appears to be attempting to escape from Asticassia. Their relationship only deepens when Suletta finds out that Miorine has been forced to be engaged to Guel Jeturk much to her horror and eventual frustration. Discovering that she accidentally hindered this by “rescuing” Miorine at the beginning of the episode, Suletta immediately jumps to Miorine’s aid and challenges Guel to a Mobile Suit duel.

Although Miorine tries to take control of her future by filling in for Suletta in a duel, even going so far as to take down Suletta’s suit (who is the Gundam Aerial), the tide quickly turns against Guel when Suletta rushes over to help. Miorine lets her pilot Aerial. Suletta instantly accesses Aerial’s powerful core technology, which allows her to quickly overwhelm Guel’s own mecha with a remote drone attack. Winning the duel, Suletta learns that she now holds the title of Asticassia’s Holder and with it, Miorine’s hand in marriage, as the two of them are now engaged to one another. Although Suletta is initially shocked at Miorine's marriage proposal, it is revealed that she is attracted to Miorine throughout the episode, and Miorine accepts her “groom” regardless of her gender, as she says so.

Episode 02

After this, the two of them become extremely close, and they work united against Miorine's father's political capitalism and Suletta's childhood trauma cause. Miorine proves how much Suletta means to her when she chooses to sacrifice her perfect opportunity to escape to Earth, one of her biggest desires, to protect Suletta and confront her dad, challenging him to a duel, where, if she wins, he'll have to accept Suletta as Miorine's fiancé.

In the aftermath of the party, Suletta appears to take her role as being Miorine's groom far more seriously as Miorine was willing to establish a company to protect both her and Aerial.

When a frustrated Shaddiq tells Suletta to convince her bride to see sense, Suletta stands up for Miorine by telling Shaddiq as her 'Groom', it is her role to support her which apparently causes Shaddiq to become more furious.

Non-Canon/Promotional
During the interim between Season one and two, specifically during March 2023, there were a number of official artwork produced along with voice acting from Suletta and Miorine's Japanese voice actors that depict the two traveling to different vacation spots throughout Japan. These spots are also said to be known for places couples visit.

Fanon
quickly became the most popular pairing for The Witch of Mercury as well as one of the most popular ships within the Gundam series fandom. Fans of the new series have been supportive of Gundam's evolution, especially in the series' treatment of queer relationships. Fans of the ship loved how well developed and constructed the two characters' relationship was and they cite their devotion and care to one another as one the things they love most about the ship.

According to Anime Trending, since its debut in October, fans have consistently voted  as the top "couple-ship" in anime. So much so that in the first week of December 2022, anime fans chose them as the most popular couple of all anime, beating out such famous couples as Bleach's couple, Ichigo and Orihime, and Spy x Family's Loid and Yor Forger. Following the airing of Episode 11, they claimed the first rank position of best couple/ship for Fall 2022.

Trivia

 * Episodes 8 and 12 heavily imply that Suletta has been brainwashed by her mother as shown when her eyes have a strange reaction to hearing certain words her mother speaks to her in order to trust her or do something that she wishes to do. Suletta's voice actor added credence to this with a tweet following the airing of Episode 12 where she begs Miorine to 'wake up' Suletta.
 * At the end of July 2023, Suletta's voice actress Ichinose Kana's mention about SuleMio's married status was censored in an interview. This soon led to Bandai Namco releasing an official statement that they wanted Suletta and Miorine's relationship to be "left open to interpretation", causing an outrage worldwide due to them backtracking on the girls' marriage and the anime showing them wearing wedding rings. At the same time, many did not see this as a surprise due to Bandai's past treatment of same sex pairings in the series.
 * Prior to the article censorship, in the immediate aftermath of the finale, the North America Gundam Twitter openly proclaimed/congratulated the marriage of Suletta and Miorine while the Japanese Twitter was more vague much to the confusion of Japanese fans.
