Well, when you read a kind of story where it's filled with people with varied magics, you will wonder what magic the main character will have, right?
for me, i think that the best superpower will be nullifying other's magic, or copying other's magic, though i think that the two will make the main character too strong and lost the intensity of the story.
But Arata here got both of them, isn't it kinda... too.. you know, cliched? or something.. though i'm not really complaining, it's nice to have a strong and good main character lead like this once in a while, and i'm a huge fan of the drawing, it's so good!!
