Why Is Sesshoumaru a full youkai?


Sesshoumaru is Inuyasha's brother, but he is a full youkai, while Inuyasha is
half human, half youkai. Why this happened? Don't they have the same mother
and father? Wasn't he supposed to be half youkai too?




They don't share the same mother. **[Sesshoumaru's mother is a dog-type Dai-
Youkai](http://inuyasha.wikia.com/wiki/Sessh%C5%8Dmaru%27s_mother)** , while
Inuyasha's mother was a human.
