When Nana joined the group, Husky was very upset and said it was 'all her fault he couldn't keep the promise [he] made with [Cooro]." (the promise being to travel with him if Cooro untied him from a large pole.) Obviously, he wants Cooro to get rid of Nana so he can stay with him. Cooro then tells him to just forget the promise and leaves, and Husky gets very depressed.
Also, he cross-dresses for cash.
He has a staff called the 'Cooro Punishing Stick'. Enough said.
