micaiah_(bridal)_(fire_emblem)
Tag used for Micaiah (Fire Emblem) from Fire Emblem specifically when dressed in her bridal-themed attire from the Fire Emblem Heroes 2020 Bridal Beloveds banner, she forms a Duo Unit alongside Sothe (Fire Emblem) (in his own bridal-themed attire) officially known as "Micaiah: Dawn Wind's Duo".
Note that it's possible (especially for older artwork), to depict Micaiah in a bride dress without it being the one described above, in which case this tag should not be used.
