Haru spent a large chunk of her life not really forming close connections to anyone outside of her family, mostly out of distrust for their motives. So she doesn’t really have many people in her life who she looks up to.
She does have great admiration and respect for her late grandfather though, who built Okumura Foods from the ground up with simple cafe chains. And despite the path her father had taken later in life, she still admires the dedication he had to the company, and still believes that man was in there somewhere.
Outside of that, she always loved and wanted to emulate the heroines on children’s shows, magical girls, especially. A lot of her role models ended up coming from tv and outside media, actually.
