Chiharu Kiyohara works diligently as a cleaning staff member in the Kuonji household, possessing a delicate, feminine appearance and a soft-spoken voice that contrasts with their male identity. Their quiet demeanor and minor narrative role cause them to often fade into the background, their presence easily overlooked—a tendency occasionally noted within the story itself, cementing their peripheral status.

A fleeting infatuation with Venis, the head maid, emerges from her rare, consistent attentiveness toward Chiharu, though this infatuation fades when Venis’s affections shift toward Ren Uesugi, another servant. Chiharu’s interactions with Ren grow strained, tinged with underlying tension as Ren’s discomfort with Chiharu’s gender expression surfaces, particularly in his refusal to share bathing facilities.

No details about Chiharu’s past, family, or broader personal growth are explored beyond their role and relationships within the central narrative.
