Her motivations revolve around maintaining that bond and adapting to the increasingly strange events unfolding around the Koda family. While she does not possess overtly supernatural abilities, her perceptiveness and emotional steadiness serve as notable strengths. Development details are limited, but her maturity suggests a capacity for growth as she continues to adjust to the presence of Kujima and the shifting dynamics within the family.
