The plot and emotional core revolve around mixed-heritage shame, the 'impurity' of white-Japanese blood, and a woman binding her chest to access male privileges for revenge against white men. Creators explicitly drew from personal experiences of mixed-race identity and deliberately crafted the story to explore 'binaries' of race and gender, with interviews emphasizing representation mandates and breaking norms.

Voice casting prioritizes Asian and Asian-American actors to match ethnic themes, framed as intentional inclusion. While the setting provides some historical cover for discrimination motifs, the modern activist framing of identity as the foundational driver elevates these elements beyond organic storytelling.

Audience reactions include notable pushback labeling it 'woke propaganda' for anti-white villainy, gender ambiguity projections, and identity focus, though it avoids explicit trans messaging or source-material alterations. These choices make progressive ideology prominent in character arcs and thematic emphasis rather than incidental.
