It was enjoyable but there is a feeling that it is missing something but it was not good but not bad either and overall I can say that this anime is not a waste of time. First of all, for some parts it was funny The story was nice and I wish they could've added more to ideas to the way the guns battle each other. Second the idea that the girls are the guns themselves but use the actual guns is nice and I liked it and with the fact that I have an interest in guns probably made me like it even more. Third the artwas on the average for me but it had cuteness which was a nice touch.

The soundtracks were nice and I think it fits the show itself
As for the story it was nice and the character development was a so-so if you may say but it is not that bad though.

And overall I can say that this anime is good.
