Tanzaku Aso

She is a senior of Class 3 and the right hand man of the Broadcast Club captain. Asa is a cheerful girl, taking pleasure in her job as an announcer. She seems to be on friendly terms with Hansode Shiranui, as she bribed the younger girl with food to work with her, though she is sometimes intimidated by Shiranui’s darker moments. She is consistently amazed by the feats of both the Swimming Club, and the Student Council. Ten years later, Aso is an announcer. (Source: Medaka Box Wiki)
