One of the reasons Mobile Suit Gundam: The Witch of Mercury was so popular during its run was the refreshing take it took on its lead protagonist, Suletta Mercury. Not only was she female – a first in Gundam history – but she was also involved in a same-sex relationship with the primary supporting character, Miorine Rembran – another Gundam first. In the series' second half, however, the Suletta-Miorine relationship was drastically downplayed and replaced by other sub-plots in the story. As a result, the series' ending left fans to wonder if Suletta and Miorine were still a couple, and if they were able to live happily ever after.
