Willow is May's eleventh vessel. He is a brown and tawny furred ragdoll-Birman tom-cat with white legs and dark green eyes. He cannot speak and is missing both of his forelegs. Because of this, he has a set of wheels to help him.
Willow’s problem is that he cannot find a friend due to his disability. He is the first vessel who can communicate with May and Imp while being possessed by them.
