Is Sesshomaru an Anti-Villain or Anti-Hero?
It's hard to tell what he is in hero or villain status. I think what happen was, that Sesshomaru, started out as a full villain, then as the show progressed and met Rin he then started to become an anti-villain and by the time of the Final Act series he became an anti-hero.
Inuyasha, I know started out as an anti-hero, but became a full hero as the show progressed.
