Jako Amano

A very popular character, she lives up to her name and has the tough personality of a gang member. She loves disco music and she has always smoked, even before she started elementary school. She and her members frequently leave class early and she often hands in blank test papers, but after meeting Ikari-sensei she becomes more of a model student (in fact, after graduating high school she studies abroad in the United States) (Source: Wikipedia)
