Kibougaoka was invented one year prior to the series start at the Mifune Factory, as the twenty-third prototype of an autonomous humanoid android called Loop. She was eventually enrolled as a first year in St. Cargo All-Girl Academy's Ume Class during her trial period. She is a freshman of St. Cargo All-Girl Academy, and formerly one of the interns working as part of the Candidate Student Council.
Ten years later, Kibougaoka develops a smart phone game with her friends, and the group plan to start a company after Kibougaoka leaves graduate school.
