ok heres the info on our lord sesshomaru,
why sesshy is like the way he is ?
its because sesshomaru had a real lover name sakura
she is so stunning very beautiful. you will never find anyone so beautiful. (shes funny too) she can be deadly too!(not gonna tell u what kind of demon she is ... i would just spoil it)(heheheh)
but she was pregnate with his and her first child his name was kai(which is a boy) she didnt give birth yet but she was pretty far along.
sesshomaru strickly told her to stay put in the castle, because he had to go to war with the panther demon tribe (asses) so he went off
sakura didnt want sesshomaru to go so she followed, sesshomaru told her to back home (but her scences were screwed) cause setosaun(sesshomaru ass of an uncle) trapped her into a invisible time wrarp
the child was never born until sesshy got together with a certain pristess!....? and
yes thats another reason why sesshomaru was so cold, he searched for his beloved and his father sword(supreme concrest) for so long he did finally faced the fact that sakura was gone and his unborn child (30 years he searched and gaved up)thats why his cold!
