Yuriko is a shorter, elderly lady with a slender but muscular frame. Many mistake her as being quite frail given her age, which could not be further from the truth; with not an ounce of excess fat on her, a large portion of her weight is made up of well-developed muscle that she had obtained during her early years as a Shinigami, and has since maintained. Even during her retirement, she worked to ensure that she maintained a good form--partly because she hated doing nothing, and partly because she liked the way she looked with all those muscles. While they're no longer as well-defined as they used to be due to to her skin being a little on the loose side, they're still quite visible when exposed.
