The director of Mobile Suit Gundam: The Witch From Mercury has confirmed that Suletta and Miorine are married to each other. This information comes from an interview that was in the final Blu-Ray of the series. [Thanks, Automaton and sgk_123!]
Here is a translation of the director’s comment, as well as the question, based on the screenshot that Twitter user “sgk_123” uploaded:
Q: The epilogue shows the characters three years after the end of the show. Is this also something that you planned out in advance?
A: We were always going to show an epilogue, but the decision to make it three years after the end came after. As for what happens in the epilogue, we took from Shakespeare’s The Tempest. It shows Suletta and Miorine as partners after they got married.
The people who worked on the show have always stated that Suletta and Miorine married each other at the end. However, in July 2023, Bandai Namco removed these implications from interviews and apologized for leaving them in.
According to Bandai Namco, it was due to Kana Ichinose, Suletta’s voice actress, making conjectures. Fan reactions to this apology were largely negative. This time, though, it is Hiroshi Kobayashi, director of the show, who is confirming in a more official capacity that the two of them are a same-sex couple.
Mobile Suit Gundam: The Witch From Mercury is readily available to stream from Crunchyroll.
