The marketing and narrative prominently feature the ongoing relationship between elf Baileys and succubus Lua, whose families oppose the pairing explicitly due to racial differences, framing interspecies romance as a stand-in for real-world prejudice and cultural clashes. This elf-succubus romance functions as a core subplot that uses fantasy races as allegory for modern prejudice, diversity, and social issues like racism and cultural expectations. Developer emphasis on relatable contemporary problems through a diverse non-human lens shapes the design and marketing, with casually queer cast and relationships integrated into multiple customer stories without being the sole focus.

Additional relationships, including those described as casually queer such as Gala the werewolf and Hyde the vampire, are treated as normal without special emphasis or conflict over identity itself. Thematic centrality arises from positioning these elements as foundational to the premise rather than incidental background details.
