Rika was an innocent young girl and childhood friend of Yuta. She shared a special connection with Yuta and believed that she loved him. These continued even after death. As a vengeful curse now, Rika desires only to protect Yuta, but her great power and protectiveness towards Yuta often caused her to harm others in the process who hurt him. While she had curse-like instincts to attack anything that was a threat, Rika still listened to Yuta and restrained herself because of her love for him.
