[ Kaneki did say he wouldn't bring Annie into this sort of thing, so no. He will deal with it himself. Try to, at least.

He also doesn't answer the question. While Nishi has a kick out of antagonizing Ken - that's for sure - he also appears to be... eager to see Kaneki's reactions. Or the consequence. In any case, Kaneki shrugs softly ]

Possibly someone that dislike him. I'm not surprised if the list is long. I don't think he cares about it, anyway, though.
