Megumi Akiba works at the Kiri Pro talent agency alongside Komugi Nakahara as her professional rival in the idol industry. Primarily an image model posing for centerfolds and posters, she also pursues acting opportunities. Her notably large chest size contrasts with Komugi's flat chest, fueling frequent conflict between them. Megumi teases Komugi about her lack of bust development, while Komugi retaliates by mocking Megumi's breasts with insults like "Hooter's Girl."

During a pool filming session, Komugi deliberately pulls off Megumi's swimsuit top, exposing her breasts to the production crew, pool attendees, and a live broadcast audience. This triggers mass nosebleeds among witnesses and causes Megumi to panic while attempting to cover herself. Scenery censorship, including a leaf and pixelation, obscures the exposure. The incident establishes Megumi as a reluctant fanservice figure.
