Girls in dragonball and yuyu hakusho. Also... cut... no, sla... no, bub... No.
Armitage. Motoko (using the original GITS movie). That girl from Zieram. Dirty Pair. 3X3 Eyes.
Actually there are a lot of girl only shows. Maybe they were always useless compared to men. Important characters covers opponents and non-useless characters, not just stars though.
Either way, besides Claymore, what else is there? Metronome? Black Lagoon counts. Can't think of anything else though.
