When Ogami came to Paris, she was the first member to meet him during a commotion in the European exposition ground. In the chapter where the Teito members (Maria, Kanna and Kohran) came to Paris as coaches to coach the Paris Flower Division, she failed all the drills. However, the coaches felt that her spiritual powers have not been awakened. During this chapter, Father Leno comes to Ogami and asks him to tell Erica to leave the convent, due to Erica's clumsiness creating more havoc. Having heard their conversation, compounded by her failure in the drills earlier, she feels she is no longer needed anywhere. With nowhere to stay or go, she wanders around the raining city until Ogami finds her. She falls sick and ends up staying in Ogami's place, where Ogami notices her enormous spiritual powers. The next day, although she hesitates at first to come back to Chattes Noires, the rest of the Paris Flower Division manages to convince Erica to come back, by making a fake emergency call. But a few minutes later, a real attack on Chattes Noires occurs. During this attack, her spiritual power awakens when she tries to save her friends from being killed by Corbeau. In the end, Erica is given a room in the attic of Chattes Noires.
