She definitly looks like Yoshika...but only seems to notice Nodoka's large breast on the first episode from what we've seen so far. Can't really comment on the manga though.
She becomes your typical airheaded type hero who doesn't seem to notice that there's a hottie lusting after her. I kinda wish she'd try something on Nodoka but then she would definitly look like a rip off of Yoshika at that point.
