Progressive elements appear in the romance system and select subplots rather than driving the premise. Conquest includes a same-sex marriage option where a male avatar can achieve an S-rank support and marry the male character Niles, with both Niles and the parallel character Rhajat portrayed as bisexual; these relationships function mechanically like opposite-sex ones for stat bonuses but yield no children. Additional subplots involve Soleil, whose attraction to women features a Japanese-version scene with a magic powder altering perceptions that Nintendo altered in Western localization to remove drugging or conversion-therapy implications, and Forrest (Leo's son), whose feminine dress-wearing and presentation lead to a father-son acceptance arc.

Nintendo publicly stated the inclusions aimed to reflect community diversity while making localization changes for Western appropriateness. These elements create noticeable LGBTQ+ representation and normalization in character arcs and supports, yet remain secondary to the core themes of war, betrayal, and sibling bonds. No evidence exists of consultancy firms, pronoun customization, or identity-politics framing as the story's foundation. Reception showed high critic and user scores with limited controversy focused on the Soleil scene rather than broad ideological pushback.
