Rose

Rose is a young red dragon that's unable to change into her dragon form. When she is first released from the case the criminal society, "FANG," were transporting her in, she knows nothing but Ryūji's name, but soon picked up a few words. Since she couldn't communicate nor knew her name, Ryūji gives her the name "Rose" because the dragon scales on the back of her left hand looked like a rose. Rose is aggressive towards nearly everyone, except Ryūji to whom she clings so much that she will sleep beside him in his bed.
