The humor in "Weather Report Girl" is full of sexually oriented sorority style humor, aimed primarily at young men. The protagonist, Keiko, is depicted as being exhibitionistic, first using her sex appeal to rise to the position of weather girl by flashing her bra and panties, and maintaining her position by frequently wearing lingerie while on the air. She is also very resourceful, always one step ahead of her rivals' various revenge schemes. Keiko is also extraordinarily vengeful, humiliating Michiko on the air by spiking her tea with laxatives after Michiko had attempted a similar tactic against her. Keiko proceeds to masturbate in her apartment while watching Michiko embarrass herself on television. Finally, she is sexually domineering, effectively enslaving Michiko—who due to the on-air incident would have been fired had she not agreed—by making her lick her lingerie and perform cunnilingus on Keiko.
