I'm interested in anime where females have the main roles and no, or only few, male characters. And not sol anime either or romance obviously(unless its yuri). Male characters are fine if they're supporting roles only like in Kill la kill

Some perfect examples I've already seen:
Battle girls: Time paradox
Queen's blade
Claymore
Kill la kill
Girls und Panzer
Senran Kagura
Upotte
Wanna be strongest in the world
Cross Ange(tolerable romance)
Witchblade
