>>1933When I first started watching SM around elementary school I gravitated towards Rei (but it was mostly aspirational, I don't think I shared many personality traits), but then as I grew older I felt more like an Ami.
Now I would probably identify most closely with Michiru even if I don't think I'll ever be as high femme as her.
I don't know if I really identified in the sense of "I am that character," but I do know that I have a preference for certain character types that lean towards to the quiet, dark, and introspective side.
