Kusuna was very overconfident and was also very sadistic trying to torture and cut up his targets. Kusuna plays the "big brother" part among Yomi's underlings and is a leadership-type. He was also shown to be heartless as seen when his team-mate Gitai was killed and Kusuna just scolded him for dying. He has been described as being both intelligent and shadowy. He apparently held the same goals as Yomi.
