Christiane Barkhorn

As Trude's younger sister, this character has a deep and devoted bond with Trude, shown through acts of care like buying a dress for her and seeking autographs for her. Following a serious injury that left her in a coma before the main story began, she eventually awakens and recovers. She shares a striking resemblance to Miyafuji Yoshika, and her name is linked to Gerd Barkhorn's wife, Christl.
