While being attacked by a crazed veteran knight, she was saved by Luke, the Sacred Blacksmith. Alongside Lisa, his assistant, Luke has the power to forge powerful swords capable of defeating the so feared demons. Demons which could once again bring the world close to an end.
I could see a lot of K-On in this anime. although not a bad thing it's hard to move away from that kinda shadow. It was entertaining, good fights and what not. But, Like many anime this one leaves many details out, which I'm hoping they can explain in a sequel. And the manga doesn't seem to be as far as the anime for some reason.... odd.
If you don't like anime with a lot of questions to be asked then don't watch this yet. You'd probably want to wait till the sequel or till more manga come out. If your looking for cute chars and medieval demon killing this is it. Just prep yourself for the questions you'll have after it's done.
