D.C was alright.
D.C SS was horribly misleading and rage-inducing, but I was originally a Nemu fan so I still liked it. The reason it was misleading was because it seemed to be centered more around Kotori but she just got written off pretty much. What's even more fucked up is the director even said it was more a Kotori-centered series, but it really wasn't.
D.C II might have a Yume or Otome ending so I'm hoping it's one of the two.
