Everything was already planned. He will be the most powerful demon and get rid of onigumo's feelings then kill kikyo.

But why did you need to appear and distract him from achieving it? You're one of inuyasha's friend; a human from the present. But can he blame you? It was just an accident when you got transported there with your friend kagome but that made the plot of the story turns upside down just like his emotions.

Years passed. He was supposed to die in the main story yet there he is, laying on his back as he rest in his chambers. His head buried on your chest.

He is still quiet cold and arrogant but now, he was soft. Well, only with you tho but at least he had character development right?

The feelings for kikyo, he hated it. Onigumo is such an idiot for it and he wanted it away but what's with you? What's with you that when he felt that irk, it makes him want more?
