The narrative prominently incorporates gender identity and queer themes as core character drivers rather than incidental background. Momoe's arc revolves around her androgynous appearance, pressure to present masculinely, and repeated affirmations of being a girl, including ripping open her shirt to declare “I’m a girl” while battling a transphobic monster in episode 10. That same episode introduces Kaoru, a transgender boy whose backstory includes transphobia, corrective rape, and pregnancy; Momoe protects him and receives his trans flag-colored jacket in a heart-to-heart exchange.

These elements directly shape multiple battles, friendships, and emotional payoffs across episodes 4, 7, 9, and 10. Additional subplots critique patriarchal idol culture, sexual abuse, and societal pressures on girls, with the premise explicitly tying eggs to female suicides due to supposed emotional differences. While the overarching story concerns trauma and resurrection, the gender and LGBTQ+ framing is not peripheral—it structures key conflicts, character growth, and the show's exploration of self-acceptance.

Audience and critic responses highlight both praise for the representation and debates over its execution, including gender-essentialist dialogue from supporting characters and graphic handling of certain traumas. No source-material adaptations or live-action casting departures apply; all elements originate in this original anime.
