Yuka is a fair person who truly cares for not only her comrades but anyone she views as people with their own wills, despite how deep or shallow her connection to them is. She highly commends "the value of life," and to this end, she will ensure that others receive a "proper death". Because of this, she believes that it is morally unethical for her to take another human life, and tries to avoid any possibility of doing so unless as a last resort.
