No doubt this anime is nuclear bomb. Story is not quite different not other anime ..like he was weak then he grow stronger for sake of her little sister. But the presenting the animation art is damnnnn..... Awesome ... graphic work damn awesome....!!!! Even they show us the camera movement graphic view during fight and all. There is no doubt anyone can ignore this series. Starting few episodes story is little bit slow but no one resist this enemy if they will keep going. For sure this enemy will left the footprint in your heart if you will watch this !
