A girl who underwent a brain transplant treatment. Once a year, she changes her body “vessel”, though she does not remember how many times that has occurred. Before the transplants, she was sickly and had a different appearance from the current vessel. One day, when she makes contact with a limp Kou, their bodies fuse together. They are now on the run from “that place” together. She is naive and curious. Her favorite foods are apples and candy. Frankly, she is tone deaf in song direction when singing. The vessels that have been replaced so far have not necessarily been healthy. It seems that she has had quite a painful past. She is very protective of her friends and family.
