Yosano carries herself with dignity and grace, priding herself on being a very strong and capable woman. While working she's very nonchalant and laid-back even in serious situations, actually she quite enjoys darker things. Yosano does have some rather violent tendencies, she can be quite sadistic and enjoys dissecting her patients before healing them; the agency fears her. She is particularly flirty towards Kunikida for reasons she will not share.
