At first, I was a little interested by the setting and supernatural circumstances that brought the reverse harem together. However, the show wasn't able to utilize it beyond the "protect these certain important items for the fate of the world but then still fail at it" trope. Everything else was just the characters sitting on top of the rooftop talking about stuff. There was also the possibility of a traitor among them, but that's rarely addressed until season two (and don't get me started with how that's resolved).
Next were the characters, and they were really bland. The male leads acted on typical harem archetypes, and the female lead was plain with her only personality trait being "I want to be useful". The interactions they had together were stiff and bland. None of them possess any good chemistry, not even the main love interest.
The other major and supporting characters were just as bland, if not completely flat. The antagonists were also typical and unmemorable, the mastermind essentially having a petty god complex.
The artwork isn't bad, but for a 2012 anime I was surprised by how dated it looked. The animation wasn't notable, especially the fight scenes.
Overall, I think there are just better otome out there that you can watch instead of this one.
