Yuiri first discovered the existence of Kojou through rumors spread at High God Forest. She was also nominated as a candidate for becoming Kojou's observer. As an avid reader of romance manga, Yuiri fantasized about developing a romantic relationship with him. However, she was not selected because she could not skillfully employ a Schneewalzer, as well as consideration for her family.
