They also realized that to save the show each character needed to be their own person so each of the characters back story they tried to make more complex they didn't do every well on the main antagonist, until the last few seconds of the after credits of the last episode, but the other side characters they did this almost seamlessly. They did put a twist on to the end in their last ditch efforts to make sure this anime wasn't a one off thing like most of this type of anime is.
It is also my opinion that their is a limit to how over powered each character can be for example the main character Shin can only get so strong before the knowledge of his past life will not be a advantage anymore and he will be forced to get his group to a almost equal power level as him in what they master in.
So this is my rating of this anime, it has the potential to be something great if we let it and we have to give it a chance, but if the writers can't get better after a second season I be leave it would be time to move on to something new. As much as I enjoy anime like this, very rough around the edges, and is based off of ideas that are not strong on their own but have potential, they need to clean up their act and come in strong the next season or this will die.
