The concept of the world is really cool. I think the powers these characters have are really cool. The songs of both season one and two were good and so was the artstyle. But I just didn't enjoy it that much. I think mostly that is because of how we get a ton of charcters in the show, but none of them seem to have been worked out. Whenever something new is going to happen in the story, they add new characters that never come back in the show.
Overall I'd just say that the character development was very poor for this show. It had a lot of potential but it never made me eager for the next episode. I was kind of happy when I finally finished this show so that I could move on to a next anime.
In my opinion the better things were:
-Artstyle of the show
-Music
-Character designs
-Cool superpowers
In my opinion not so great things were:
-Story gets the same after a while
-VERY poor character development
-Too many charcacters to really choose one to like the most
-gets boring
That's the end of my review.
