After her father's death, Jeanne and Tristan were taken in by Sigurd's army. After the events of Chapter 5, they fled to Isaach with Shannan, Oifey, and Seliph. However, she was eventually separated from the others and found by a traveling merchant, who took her in as his daughter. When she was seven years old, the merchant was murdered by a soldier of the Grannvale Empire and she was thereafter adopted by Finn, who raised her in hiding alongside Leif. In Chapter 7, she fights alongside Leif and Finn to defend Leonster from Bloom's army.
