The cast features extensive Ho Yay ship-tease between male characters, including living arrangements, declarations of love, and one explicit marriage proposal rejected due to legal barriers. Narukami Arashi stands out as a focal character whose gender expression receives dedicated narrative attention: Arashi uses feminine self-references like "atashi," prefers "onee-chan" (big sister) address, discusses struggling with gender in later stories, and is interpreted by many as transgender or non-binary.

English localization frequently avoids pronouns for Arashi, sparking fan petitions and wiki edit wars over she/her usage. These elements create noticeable LGBTQ+ representation and subtext that influences multiple character arcs and events without forming the core premise of idol industry drama or rhythm gameplay.

Developer Happy Elements shows no DEI consultancy involvement or activist marketing statements; the content aligns with longstanding Japanese otome/idol genre tropes rather than contemporary Western social justice framing. Reception highlights character charm and music over ideological debate, with controversies limited to localization choices and isolated story lines rather than broad backlash.
