I have never read the light novel of this Anime, When I watched it, I really liked the plot as it is one that I have never seen in other Anime(s) to date. I also play a various amount of video games, so the setting and how characters were animated appealed to me quite easily. The characters were two good looking teenagers that anyone would love to continue watching. They were also strong, when some Anime, the main characters are absolutely useless and rely too much on other people. This makes their independence more outstanding. And when they work together, they achieve greater power.
The Second Half/Ending of this Anime was a slight disappointment to me when I was really hooked onto this series. Just a personal opinion here
