An anime about a samurai who has extended canines There's an anime I used to watch about 7 years ago on animax.
I cannot recall it's name.
Some information:


It was about a samurai.
He wore a red dress that covered his full body and draped from his arms.
He has extended canines.
He sports a long grey (or white) hair. 
He says something (rather yells) that changes his look or something like that.
He has a hot girlfriend. ;)
He had an enormous sword.More specifically, a sabre.
2 or 3 seasons of this anime aired. There were a couple of movies too.
I remember Animax dedicating a whole weekend to this anime.


If anyone can give me any suggestions, it'd be appreciable. :)
I believe the anime you are looking for is Inuyasha. The anime has lots of episodes, aired on Animax, and he has fangs, red drapes and shouts.



Fangs, Check



Sabre kind of Gigantic Sword, Check



And long red drapes, Check



The only problem is that his girlfriend does not look that hot to me.
