Age:15 -> 17 (3rd grade)
Kokoa is a highly excitable girl with a bubbly disposition and a sweet tooth. She is also very clumsy and air-headed, causing many accidents. She is always smiley and optimistic with a strong determination to do her best with anything life throws at her, and her unbridled enthusiasm usually convinces the others to try new things. Despite her ditzy disposition, Kokoa has the rare ability to mentally calculate all arithmetic instantly, much to her coworkers' surprise. Kokoa desperately wishes that Chino would recognize her as a big sister figure. Although Chino rarely complies with her wish, Kokoa still likes to imagine Chino is her little sister regardless.
