At the mention of other demons, Hiei's anger flared up, showed by the scowl on his face. Oh, he knew another demon quite well, yes...but that particular demon wasn't wanting to be pointed out, instead preferring to drown himself in his human disguise.

How quickly his fury at Kurama rose up again.

"Only one." Hiei knew Kurikara wasn't a demon, and the woman from that morning was just insane. "But he isn't worth mentioning."

Isn't worth mentioning, isn't worth thinking about. If Kurama wanted to be human, then fine. Hiei wouldn't care. He'd just stab his spaghetti harder for a few minutes.
