miki has always been "cool" and "tough"... even during her solo days, dare I say, a contrast to Ayaya's (former) bubbly persona... it could be seen from her (few) solo songs, (except, Boogie Train i suppose), to her image.
in her own cool way, the "cute" aspect comes out... not in an overly forced or "childish" way (sorry, but, ugh, reina), but in a more natural "miki" way. like, (hehe, sorry SitS), the way she seemingly likes to grope, her liking for niku, her death stare, etc... small things, which make up her cute aspect.
