Inside of Isiah, there was a huge war going on, the part of him that felt hungry was pushing him to torture and kill Kuma, however, there was that tiny part of him that hates this stupid feeling .
Isiah was already trying to make Kuma suffer before he killed him for hurting Ciel that way yet when he heard Ciel talking behind him he just felt that he went too far.
Yet, he wanted to continue what he was doing even when Ciel was standing there looking at him with his red eyes .
He immediately looked at his bruised neck and automatically his anger increased to the point where he turned around and grabbed Kuma by his collar.
Ciel was very pissed that Isiah ignored him that way and for that, he just said this time with a husky voice:" I want to talk to you"
