I like this anime so far as its uniqueness comes from the story of humans, espers, magicians etc. It seems to be unique that each of them dont know other kinds really exists. To put it simple, Espers dont know magicians really exists while magicians dont know espers exists. And its quite interesting to see one of the kind meets another kind and gets in role.
I can't wait to see the next episode because it's story is really going through well. The characters are really well made such as their personalities, appearances, etc. The anime does not really have random events coming to story. The events that occur in the story are somehow related to one of the main characters from the past.
Another of this anime's uniqueness is Touma's (Esper as well as the main character) lost memories. As you can see in the beginning, his memories are lost; however, he manages to keep it a secret to everyone around him. The ability to keep the secret quite makes a difference from other animes where characters tend to forget someone and people notice that.
I think anime's uniqueness really makes the series good so far.
