Story:
The story progresses with each episode, and every episode is connected with each other. On the other hand, there are too many confusing elements in the story that doesn't make any logical sense. This story supposedly takes place in a real-life situation, yet all of a sudden, the MC has a supernatural ability? That ability is never touched upon again after a few episodes.
Characters:
I think they did a good job with the characters, all except for the MC. The MC was the driving force that almost made me drop the series altogether. Yes, her character did undergo progress. But it's always to the extremes. She started off as this emotionally and mentally weak girl, so weak that you would get mad. Then she became this over-confident person, to the point where she acted as though the world revolved around her. In all honesty, I hated her character the most. I just wanted one of the characters to put her in her place. She's too power-hungry, for a lack of better words.
Overall, I did enjoy this anime, albeit not as much as other anime, but I wished that they would have made the MC a better character.
