Principal Dale holds a counseling role at the Tokyo International School in The Grudge 2 and is addressed throughout as Principal. She is a supporting figure connected to the school attended by the student characters Allison, Vanessa, and Miyuki, and she represents adult authority within their everyday world.

Her part in the story is tied to the school setting. When Allison becomes disturbed by what has happened to her in connection with the Saeki house, Principal Dale tries to calm her by insisting that there is nothing to worry about and that the house is simply an abandoned building. This rationalizing response places her at odds with the reality of the supernatural events the students have encountered. In an extended scene, the ghosts of Vanessa and Miyuki appear to Allison in Principal Dale's office, making her workspace one of the places where the haunting reaches into ordinary institutional life.

In personality, Principal Dale comes across as calm, pragmatic, and professionally reassuring. She responds to the unexplained with practical explanations rather than fear, and her motivation is to keep her students settled and secure while maintaining a normal atmosphere at school. Her key relationship is with Allison, whom she attempts to comfort and redirect, and she carries a general duty of care toward the student body. She does not undergo personal change over the course of the story, and her significance is chiefly institutional rather than personal. She demonstrates no special or supernatural abilities; her function is that of a school official who stands for dependable adult order while the threat around her students grows.
