This first season of this anime, is unique from beginning to end, they do a very good job of engaging and trapping the person who watches it, each character has his or her own amazing personality traits that make them a great and well rounded character, this anime was very well thought out and has much detail into it, and each character has their own unique powers, that has each a strength and weakness, as well as it's own limit to how much each person can stand, like stamina for example, some characters last longer then others in terms of how long one can bein combat.
