First episode wasn't half bad if it were a pure comedy. Sadly it isn't. The second episode tried to present itself as the 'shit starts getting revealed' episode which was nice and all but this supernatural theme they're trying to do just isn't working out. It just feels like they made a slice of life/comedy and someone suggested that the fans would get bored of that so they all just agreed on adding some supernatural aspects as a spice. I was already skeptical at first and now I can see this show falling apart pretty soon. The characters are pretty boring too. We got that tragic-slash-mysterious-slash-mischievious girl, the megane goofball, klutzy imouto, and a guy who got dragged in and has no idea what's going on... Are they sure this isn't a pure comedy?
Overall, I'm disappointed and uninterested. I can't see this show redeeming itself with these characters no matter how many twists they pull. Hopefully Key makes a miracle happen though.
