She's the only reason I even watched the series in the first place. Normally, I wouldn't watch this type of series, but I made an exception for her and I still didn't like it. This is the only time I've been compelled to watch an anime for that reason.
Not sure exactly how good the manga is as I've already recently downloaded it and only RAWs, but I notice a lot differences from the anime. Outside of all the filler the anime had toward the end, there's a lot of differences like events ordered differently, some scenes with minor characters that weren't in the anime, and a lot of little details. I can say, however, that the anime is a bad adaptation whether the manga's very good or not.
