Dirge of Agatha

I was listening to Kikyo's death theme (Inuyasha) [ listen here: www.youtube.com/watch?v=Q8HsFx… ]
and I felt melancholic, I don't know why. The song is really beautiful, I couldn't explain it
So here's the inspiration, Agatha resembles Kikyo. And yes, that's her Shikigami {Shinidamachū} that collects wandering souls. 

Though Kikyo is my least favorite character in Inuyasha, I felt sad for her death in the second season, Inuyasha: The Final Act
