I had seen the visual for this show prior to watching and that was it. Consider what little expectations I had leading into this first episode far exceeded. The story is still very opaque, but they really delivered on action and aesthetic in this episode. There is clear use of CG during action sequences, but with heavy use of 2D animated effects, fast motion, and really good effects on the 3D to mesh it all together, the final result was really great. These battle suits they wear make me think of Genos from One Punch Man and Viola even had an inferno-style ability that she used.
Anime original series can always be a bit of a wild card because there isn't as many people out there to help set your expectations, but I am on board for this one going forward. I just hope that they can continue to produce the same quality in the action while slowly revealing the story and world to us as we go.
PS: please let the story be good. I love the action and style that has been shown so far, but if the story is a stinker then the fun of the show will feel a bit hollow at the end of it all.
