I finished Cross Ange after a long binge watch. I think that for an ecchi there managed to be a lot of story there in the end.
The mecha battles didn't feel very original, and I kept on feeling like it was so bad at some times, but then so amazing! It's funny how I know they could do some changes here and ther eand it'd be a greater anime, but I guess the main aim was for ecchi haha.
I enjoyed it. It takes a long time to get to the point but it was an interesting anime watch. It also revived me to watch anime for the season so that was great!
