This series had such a great start but it went downhil since this Legion came into the picture. The idea was Dark fights Light from the Dark's perspective, not the other way around as usually does, I particularly enjoyed a whole lot of the mental games she has pulled against Tres Magia, but they suddenly vanished, poof just like that, what was the purpose of them anyway, author-san?
Seriously, if you takeTres Magia out of equation, you fundamentally remove a key part of this story, and got this super rushed Legion arc out-of-freaking-nowhere.
I got my complaints but I bring solutions too, I'd go with a solo, badass magical girl solo, resembling and acting like an angel but actually hiding a true purpose, not to brag, but definitely a better route than this and being true this series initial concept.
