Chikaru has shown herself to be a natural leader as she is the president of several functions: the student council of Lulim, the Transformation Club (where members dress up in different costumes), the Secret Club (where members try to solve mysteries), and a variety of other clubs which she regularly creates, such as the Waiting First in Line Club. She has a friendly personality and enjoys helping others when they need it, which makes her an excellent candidate for the student council. Also, Chikaru tends to be very knowledgeable about the schools and their inner workings. When in Astraea student council meetings, she often lets the other two school representatives argue with each other while she sits back and observes their behavior. She is not easily perturbed and frequently helps out those who have trouble, regardless which school they attend.
In the manga, Chikaru notes that she and Shion Tomori are childhood friends, and she affectionately calls her Shion-Chan.
Chikaru has exhibited a strong familiarity and faculty with the arts in costume design, costume creation and acting. She plays the title role in Astraea's production of Carmen, as well as designing the costumes for the show.
