Able to keep his composure in most circumstances, Kuro is very confident and objective. He does things even when he doesn't have to because Kuro knows that what he is doing is for the greater good. At the same time, Kuro is willing to be rough to get his point across. He is witty and enjoys teasing others, but always means well. He tends to be quiet at first, and two-faced. Once you get to know him, he’s a lot more relaxed.

He is bilingual in Japanese and English.
