Very great series. The fan service is low and the story and fight scenes are very good. I thought it would be a normal hero story with linear A to B story lines I was pleased this was not the case. The plot changes was very unexpected which kept you wondering how things would play out and for whom. Early on you find yourself empathizing with the secondary main character then kinda disliking her then liking her again. You find the inverse with the main character. The background characters are easy to connect with and to be honest Vivio is my favorite a even better storyand development than the 2 mains.
It leaves you on a cliff hanger but apparently Vivid Strike Specials has the 13th episode. I'm on my way to that.
