Yoshino is a slim woman with long brown hair. Yoshino claims to oppose her superior and lover, Jin Kariya. She resembles Uryū Ishida's mother in appearance, but it is stated that the Bounts can not produce life. Yoshino seems to be the exception to the rule, as it was stated that she could reproduce. Yoshino also bears a great resemblance to Rantao, the creator of the Bounts.
