Isshiki Iroha is a first-year student of class 1-C in Subu High school, first introduced in volume 7.5. Hachiman sees her as a "not cute Komachi" or a "better version of Sagami." She acts in front of anyone to maintain her "cute appearance", but she showed her true colors just to Hachiman.

She is one of the Shichibukai and captain of the Kuja Pirates. She is the Empress of the Amazon Tribe on the Isle of Woman. She detests the World Government, but wants to keep her Shichibukai title. Her immense beauty belies her cruel personality, as shown when she kicks a kitten in her way.
