Yeah spoilers button works well for this thread.
Have Bakemonogatari as well, need to watch that.
Here goes one of my favorite manga of all time: Kiseijyuu
So damn good and no anime adaptation that I know of
If you guys haven't read that, make it so.
As far as anime on my initial list a special one would be Texhnolyze - that's the shizz
Seiya, I have watched as a kid and am still watching as it continues with a new one on air now. The OVA, lost canvas is hell good, currently watching that. The original series is hell brutal and crazed and that used to air on like saturdays during the kiddie shows lol.
Basilisk/Kurozuka, the best ninja ones I can reccomend. Used to read the Basilisk manga as well, so badass. So ninja.
