I’d like to see Pumpkin Scissors and Zipang completed up to the ends of their respective manga (although Zipang was controversial enough that it might be really difficult to get it made). Likewise, Kamisama no Inai Nichiyoubi up to the end of the light novel series. And, just as an extra, it would be nice to see the last arc or two of Ghost Hunt make it to anime, although that would have to be an OAV as I’m pretty sure it would make six episodes max.
