Like Risa is not taller than Miki.
Well, if the chart is accurate it's only by one centimeter. difference And remember that the girls often wear those shoes with the massive heels, so their "height" as they look on TV appearances may not necessarily be accurate either, whereas their "official" height would have been measured with all of them barefoot. The differences are all minimal (the largest being 20 cm between Kaorin and Aibon), and to be honest, not worth quibbling over. If they were, there'd be a debate/argument going over whether or not Sayu really does have the largest rack amongst current MM members.
