Replaces the layered wear items Cashmere Cardigan [Ou] (カシミヤカーディガン[Ou]) and Chiffon One-piece [Ba] (シフォンワンピース[Ba]) with the clothing of the Mother Cluster Apostle Och Miller, the Prodigy Mathematician. Just a side note, if you want the base clothing to be white you have to use the snow variant シフォンワンピース雪[Ba]. Also Miller and Lasswitz use the same base ware.
