Just finished it and loved this show. If you're into magical girls with a dark twist this is for you.
I get that "magical girls" genre is supposed to be cutesy and stuff but this is a whole other level. It's not your typical "kawaii" magical girls, but instead it has a twist. It isn't too dark, but it isn't too innocent either. Watch this if you're looking for something with shocking plots.
In-fact this is the only anime i've only left a review on because it's that good! The only bad-ish side is the ending which was a bit confusing for me because i'm a slow reader, but the anime overall was life-changing. A lot of people are saying this anime is dark and scary, i slightly disagree. I am 12 years old and i was able to watch this, however i will admit some scenes were a bit gore and harsh so i wouldn't recommend if you're sensitive to stuff like that.
To all the people saying it's a "disgrace to magical girls" just care about cutesy kawaii loli girls with a fluffy anime story, but this anime is something different and unique. Not all "magical girl" animes has to be the same or have a typical storyline, i feel like this show was more of a reality. Personally, it was a great show with a lot of plot twists and shocking moments for me.
