マミはショーで使う伝説の花嫁衣装｢マリアンの瞳｣の胸の部分に血のしみを見つける。そしてマリアンの瞳を着ないで、という奇怪なハガキがマミの元に届く。差出人は紅小路鏡子という女性。マミは彼女の家を探し当てるが、鏡子は10年前婚礼の日に胸を突いて死んでいた。
Upon arriving at Parthenon Productions, Creamy Mami has it explained that she is to participate in a fashion show the next day whose feature presentation is the wedding dress known as »Marian's Eyes« whose colorful prologue includes a curse that makes all the women who wear it commit suicide; after completing her henshin, Mami encounters the dress in the adjacent room with a bloodstain on it and again when Megumi is unsuccessful in fulfilling the required dimensions of the unsoiled dress. If that is not unsettling enough for Mami, Producer Todoroki signaling an interest in Kyouko Benikouji along with a postcard admonishing against wearing the »Marian's Eyes« becomes the forum for the mystery of finding a way to defeat the dress's suicidal curse. The only way is to incinerate the dastardly dress -- a volition that the circumstances successfully stalemate; the ultimate irony is not that Mami is a tough customer but that the whole thing is an authentic but slightly cruel double-blind
