These supports, while not mechanically represented the same way heterosexual relationships are, still showcase and promote a healthy homosexual romance. Both of these characters have paired endings, where the characters promise to “spend forever together”, or joke about how they’re already an old married couple.
While the series first took a foray into “proper” canonized gay supports with Fire Emblem: Fates, you can go back as early as 2003’s Blazing Blade to see implied same-sex relationships through the characters of Lyn and Florina, as well as Lucius and Raven. While not everyone has been a fan of the more Otome style of gameplay this has encouraged, with a focus more on making two characters kiss and joke around instead of the horrors of war, it’s undeniable that the implementation and evolution of Supports have brought Fire Emblem to the acclaim it holds today. In most recent games, the system has become polished and simple: you put two characters next to each other in battle and over the course of your war campaign they’ll go from begrudging strangers with differences to the best of friends (or maybe more).
Originally designed as a hidden mechanic to merely buff adjacent characters for story purposes, the conceit gradually evolved more and more with games like Genealogy of a Holy War adding a child-rearing system, and Binding Blade adding customized cutscenes for any given pair of characters. When it comes to talking about Fire Emblem, the support system is inevitably what comes to the forefront of the discussion. While headlines have recently been made thanks to the rough implementation of canon same-sex relationships in Three Houses, the Fire Emblem series has always had a history of LGBT subtext that feels both ignored and underrepresented.
