I thought shes suppose to be a dragon ? not a holy sword user O_O
So why did they say Dragon in the title ?  If she was, I would expect she shapeshift back to her true dragon form ? All that happened is she pulled out a holy club...... Then rather than teleport, she would take to the skys in flight.  Thats so fucking undragon like. 
First chapter gets a fail stamp from me.   Author should learn what dragons are before using them.
