Protagonists Mizuki and Ryuki, along with AI partners Aiba and Tama, follow established franchise lore without gender or race swaps to prior characters. Minor progressive touches appear incidentally: the AI Marco is deliberately written as non-binary per creator Kotaro Uchikoshi, Mizuki expresses support for LGBTQ+ groups as part of her protective personality, and Ryuki receives fan-noted implications of bisexuality tied to mentor admiration for Date.

These elements remain secondary to the detective story and eccentric anime-style humor, with no pronoun customization, character-creation overhauls, localization censorship, or developer DEI mandates. No Sweet Baby Inc. involvement or activist marketing statements exist. Reception shows consistent critic-audience alignment around 8.0-8.5 on Metacritic with no backlash tied to messaging.
