Miki Fujisawa serves as the older sister to Tomohiro and Ruri Fujisawa. Employed as a manager at Sweetfish Productions, the company overseeing the Lovely Idol groups, she played a direct role in her brother Tomohiro's career path by introducing him to President Mariko, securing his position as a manager within the company. Possessing a somewhat tomboyish personality, Miki frequently engages in playful physical interactions with Tomohiro, such as hitting or attacking him in a characteristically sibling-like manner. This behavior consistently evokes a degree of apprehension in Tomohiro during their encounters. Miki's relationship with her younger sister Ruri remains visibly strained, marked by Ruri's cold speech towards her and a notable absence of familial address like "big sister."
