How about
Lupin III: Mine Fujiko to Iu Onna? Fujiko's also on the team in the 2015 revision of Lupin III set in Italy. It's only in fansubs. In both shows Fujiko is voiced by the remarkable Sawashiro Miyuki.
I agree with your assessment of Ryoko. If only the stories were as good as her character.
I found Fremy in
Rokka no Yuusha rather sexy though waif-like. Being voiced by Aoi Yuuki helped, too.
The girls in
AKB0048 are cute but largely jailbait. The fights are fun to watch though. You'll know after two episodes whether you want to continue.
