Girls with Guns

I really liked Hakuoki - I have all five Blu-rays above plus the OVA DVD "A Memory of Snow Flowers" from Sentai. I showed this series to my mother and she really enjoyed it too. I'm not really into all the bishy guys, but in general I do like reverse harems much more than regular harem anime, because the stories are usually more grounded and serious than what harems dole out, which tend to include a lot adolescent fanservice and comedy and come across as being more immature. Plus there's all the historical flavor of this series, which is a big plus for me.
