The narrative centers on friendship bonds, truth-seeking against media fog, and self-acceptance through Jungian psychology, with episodes focusing on investigations, rescues, and character dungeons rather than ideological messaging. Casting uses standard Japanese voice actors for all-original Japanese high-school characters in a rural Japanese setting, with no race- or gender-swaps of established figures. The story's handling of personal identity remains grounded in individual growth rather than contemporary activism.

Kanji Tatsumi’s arc confronts a hyper-masculine persona and sewing hobby via a bathhouse Shadow implying homosexuality, resolved by accepting hobbies while affirming heterosexual interest in Naoto. Similarly, Naoto Shirogane presents as male for professional respect as a detective; her Shadow explores gender presentation but resolves with acceptance of being female, framed as overcoming societal bias rather than identity affirmation. Creator interviews emphasize murder mystery, media critique, and personal truth over activism, and the 2011 anime contains no lectures, DEI mandates, or premise-altering changes, even as modern progressive critiques note the arcs reject queer readings.
