A flamboyant actress, Kaoru has an extravagant personality. She is rather pretentious and bombastic, having a tendency to use impressive-sounding words to the point of sounding foreign and hard to understand. She views herself as a prince and sees other girls as princesses, while quoting Shakespeare or other philosophers (sometimes incorrectly). She appears highly flirtatious and is very popular among other girls, not only for her passionate mannerisms, but because she is also surprisingly reliable. If she is aware someone may be in a bad mood or feels sad, she will try to encourage them or help them feel better.
