The six main playable characters—Noah, Mio, Lanz, Eunie, Taion, and Sena—form heterosexual romantic pairings, most prominently the canon Noah-Mio relationship built through shared off-seer rituals and interlink experiences, with no gender-agnostic dating, pronoun selection, or character creation systems replacing male/female options. Thematic centrality remains low, as identity politics and systemic oppression framing are absent from the central narrative and developer statements. The moderate score stems from explicit non-binary elements that stand apart from the core story.

Supporting character Juniper uses they/them pronouns in English, is voiced by non-binary actor Lilly Hart, and features an androgynous design as an optional colony commander and hero quest participant. DLC Future Redeemed introduces A, whose gender is described as 'somewhere between' male and female through Rex's dialogue referencing the Trinity Processor. These additions occur without race or gender swaps of established franchise characters and without activist marketing or DEI consultancy involvement, keeping the progressive content peripheral rather than foundational.
