Haruka knew Yuiko for quite a while, even before Riki recruited both of them.
Albeit their relationship isn't anything "deep", you have a good idea that Haruka respects Yuiko quite a bunch, and put her on a pedestal (hence why "Anego").
Haruka oftens acts like Yuiko's "henchman" or "sidekick" without being too clingy. Still, she is arguably friendly the most with her than anyone else (save Riki when you reach Haruka's route, obviously).
So the absolute lack of interactions, then the messed up name calling are beyond me.
