I've been reading this manga for years, and it started off with some potential. Over time though, it went downhill.
The manga started off as an edgy magical girl series about Asagiri Aya and and how unfortunate she was. It continues with her journey of learning about the magical stick and learning more about the magical girl site. Once they introduced the tempest, it was interesting, but the interest faded away through out the years because the idea of the tempest was introduced so early in the series, but it wasn't a plot until the end.
The amount of characters through out the series is insane. I couldn't keep up with the characters, especially in the end of the series. Though the manga had new chapters weekly, it felt like it took forever to convey the message.
The ending was one of the worst I've ever read. It just felt so rushed and made little sense. The actions the characters took was not explained well and made me confused every week.
Overall, I would not recommend this, especially if you're looking for something with a good story.
