The protagonist can be chosen as male or female, which is purely aesthetic for the main plot but determines available romance options in the bond system. Same-sex romances exist, including Zelos as an option for a male protagonist and Sybil or Diana for a female protagonist, with several characters portrayed as bisexual.

These elements appear in the optional support conversations and endings but remain secondary to the war story, prophecies, and Nephilim chosen-one narrative. The fictional setting includes organic cultural variations like Sayunaari characters with darker skin tones tied to lore about their homeland, with the developer explicitly stating no intent to mirror or exclude real-world Earth races.

No pronoun customization, body-type swaps, localization censorship, or activist statements from the small indie developer Dancing Dragon Games appear in any sources. Reception is strongly positive on Steam with no notable backlash or critic-audience gaps tied to ideology.
