I can see plenty people relating to Shizuka, regardless of sex and gender: she's pragmatic, a bit over-analytical, hides her emotions under a façade of coldness, and she gets deep into what she wants/needs to know. If you have a few of those, it's only natural to relate to her.
I guess that IRL I'm a bit of a middle ground between Akira and Shizuka. I'm not working in a black company but I follow the rule of cool, like him; but I also tend to hide emotions, like her.
