Kagome is the one singing to Sesshomaru about Inuyasha. Inuyasha was hurt really badly and she needs Sesshomaru to help hi he is the only one who can.
I don't know if you can hear me
Or if your even their
I don't know if you would listen
To a miko's prayer
Yes I know I'm not an ally
I shouldn't speak to you
Still I see your face and wonder
If you loved your brother too
Sess help your hanyou
Hated from birth
Show him the mercy
He won't find on earth
Sess help your brother
He looks to you still
Sess help your hanyou
For nobody will
Some ask for wealth
Some ask for fame
Some ask for glory to shine on their name
Human's ask for love they can possess
Demons want to live where
Their not their to bother
I ask for nothing
I can get by
But I know your brothers less lucky than I
Please help you hanyou
The poor and down trod
I thought you were here
To help out your lands
Sessh help your hanyou
Brother of Yours
