text: inuyasha fans? does anyone know who sesshoumaru's mother is and/or what kind of demon is was.   i know about inuyasha's mother but know nothing about sesshoumaru's. sesshoumaru's mother is/was never mentioned. she's not a part of the main plot(or any of the main characters' lives). inuyasha's mother was mentioned only because they needed to show how and why inuyasha has mercy and feelings for humans.  sesshoumaru's mother isn't ever mentioned. i have the thrid movie and though you met(see) a younger sesshoumaru, and his father(they're identical!), his mother is never mentioned or seen.  most likely, she won't ever be brought up.
