Crona adjusts to life at the DWMA and attends a party with Maka, Black Star, and Kid. There, Crona meets the revived Medusa, who instructs them to locate a vault within the school. After searching, Crona is discovered by Marie, who escorts them to their room where Eruka is present. Through Eruka, Medusa broadcasts orders for Crona to place a liquid into Marie's beverage. This action allows Crona to overhear conversations between Marie and Stein. Subsequently, Crona visits Stein's residence to speak with Marie and proceeds to add the liquid to her drink as commanded.
