First of all if you are looking for great fantasy actions this is not for you. From the title of the drama I thought this would be an action based drama but unfortunately even though there are some action scenes, they were not great and there weren't too much of them either. It's mostly drama and romance and bromance in a school setup.
The story and drama was good. The romance was cute and the bromance was interesting.
The story got draggy at the later half of the drama but the last few episodes picked up the pace with a satisfying ending.
Overall it was a unique drama and it was a slow but somewhat fun watch. If the pace was a bit faster it would have been a very fun to watch drama.
