Notes: Sesshoumaru is the full dog-youkai (demon) brother of Inuyasha. He hates his brother and humans in general. He is pretty calm and collected, confident, proud and powerful. Not exactly evil, but the enemy of Inuyasha, so he is seen as the bad guy of the series.
I've only seen up to the 20s episodes, but I hear he becomes a bit nicer later on in the series.. ^_^ Sorry again for the lower-quality screencaps. I'll take better ones if I get the DVDs. ^_^
