Well two of my favorites manga never got an anime adaptation :
-
Angel densetsu ( Norihiro Yagi's superior manga )
-
Katsu ( Mitsuru adachi )
I thought
kyo kara ore wa also didn't have an anime adaptation but apparently it does ( I need to check that ! ) but it's only 10 episodes, so definitly not what a 38 volumes long manga deserve.
Holyland, would have been better than a drama.
Then looking at my manga collection.... so many more,
Get Backers deserved to go the end, same with
Fruits basket.
Some Boichi's story could have been pretty nice too (
Hotel or
Sanctum ? ), That art with good animation :drool:.
On the Shojo side
Cat street,
My Girl (Sahara Mizu) or
Musunde Hiraite would be instant buy from me.
( etc.. etc... )
And the best for the end :
Beck, it deserved to cover the entire story, I don't even know what the rest of the story is, why ? because the anime make it so much more awesome because of it's incredible ost, that I just never could read it as a manga.
edit: and I don't care what the others say, the last part of
should have been covered by the anime. :yup:
