Kagura's heart was in Naraku's hands from the very beginning. As time went by, it was only natural for it to change.
It began to develop thoughts of its own, independent of Kagura.
As a bystander, it witnessed Naraku's obsession with Kikyo.
No one could remain unmoved by that obsession.
Not even it.
Alas, the saddest thing is that you understand your own heart only after you kill your lover with your own hands.
Very touched~Thank you! I'm starting to understand why you prefer Platycodon so much, even though I love Naraku~~
