He grew up on a nice place! Looks like Mother was a noblewoman, judging from her attire.
Wonder what happened for him to become desperate for power-
Mother died when he was young, what circumstances moved him away from this place?
Could it be...his brother, introduced last episode as 'The Fearsome Prince'?
I mean, the guy looks elegant, has an air of calm about him, and wasn't spawned from Mother.
 Hmm, and Father holds some titles, being a Great Daemon.
 Hmm... Sessh seeks the Fang, and made a sham of Inuyasha's mother in his game of finding
 Father's grave. He said this would increase his power...

Now, I call this sham of a Mother 'Chimera', because it is an odd-sounding word and
is synonymous with 'phantasy'-let me also spell it that way because this is ethereal.
She's faceless! Kagome can't move to warn Inuyasha.
What does this apparition of Inuyasha's past play in Sessh's game?
She's using Inuyasha's memories to gain trust...
On another note if one is curious and remembers some Greek mythology...this Looh doesn't refer to that.
I mean, this is fabricated from Inuyasha's mind, his Mother being one from his past.
