1. Liar Game - live actions were horrible, it should get much better adaptation
2. March Comes In Like A Lion - it already won some awards, so I hope there is a chance...?
3. Mononoke Soushi - I want to see what Nakamura Kenji would do with it (the guy who did Mononoke), but it will probably never happen
4. Hanako to Guuwa no Tera - I can't stand the fact that out of two works by the same author, the one to get its anime was Mirai Nikki (it's horrible imo >:(), while this one - being much better - is underrated and will probably never get an anime
(no offense to Mirai Nikki fans, I just don't like it but love the second one and I can't help but feel somewhat frustrated...sorry)
5. Zekkyou Gakkyuu (Screaming Lessons >:D)
6. Cat Street
7. Tousei Gensou Hakubutsushi
8. Kiben Gakuha Yotsuya Sensei no Kaidan - actually, it would be nice if the manga also got continued (it was ended quite abruptly), but nevermind...
