Megumi Akiba serves as an actress and model at the Kiri Pro talent agency, positioned as Komugi Nakahara's primary rival. She routinely instigates conflicts with Komugi, deriding her as a "pseudo-idol" and ridiculing her cosplay interests. Komugi retaliates by criticizing Megumi's modeling work and emphasizing her physical attributes, fueling their constant bickering and competitive clashes within the agency.

Vain and combative, Megumi frequently provokes arguments beyond her rivalry with Komugi, targeting others at Kiri Pro. She exhibits intense pride in her physical appearance, particularly her chest size, which she considers a professional asset. This fixation triggers significant insecurity and frustration when facing perceived rivals like Koyori Kokubunji, whose presence threatens Megumi's self-proclaimed status as the agency's top figure in this regard. Despite her confrontational demeanor, Megumi shows deference to agency president Yui Kirihara, primarily motivated by apprehension over undesirable job assignments rather than authentic respect.

A minor production note highlights an inconsistency in Megumi's character design during the series' TV Special (Episode 2.5), where her eye color appears green instead of her typical brown.
