Seta Kaoru

Seta Kaoru is a third-year student at Haneoka Girls' High School and the guitarist of Hello, Happy World!

She is very popular with ladies, whom she dubs her "little kittens" (子猫ーちゃん, koneko-chan). Himari and Rimi in particular have a tendency of blushing in her presence.

Outside of the band, she is also Chisato's childhood friend, and their parents are good friends as well.

Appearance
Kaoru is a tall girl with angular facial features, slanted crimson eyes, and long purple hair worn in a ponytail. She has chest-length forelocks and bangs that frame her face with a single lock that hangs loosely between her eyes.

Her casual attire is normally boyish and formal. In her initial casual wear, Kaoru wears a high-collared white shirt with a black vest on top of it, black vertically striped loose pants, and a pearl necklace as a finishing touch.

During winter Kaoru wears a gray sweater with white stripes at the top and bottom, a black loose scarf around her neck, and white jeans. During summer she wears a white front tie shirt which has black flowers on the left side, a blue shirt underneath, and high-waisted jeans with a brown belt. Her outfit is completed by a thin chain necklace.

When she was younger, her hair reached only up to her shoulders; after middle school, she started growing it out.

Personality
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.

When by herself, her "quirks" seem to lessen, if not vanish entirely at times. She appears to be aware of how she can come off to others; sometimes she struggles to have time to herself due to having so many fans and is aware that she likes certain things that don't fit her "character". She is even able to increase her actress's personality if she feels it is necessary.

Though she appears very intelligent, she can often be just as airheaded as Kokoro and Hagumi - such as mistakenly assuming the philosopher Friedrich Nietzsche was a woman, or repeatedly attempting to push on a door that could only be opened by pulling. Her catchphrase is "fleeting", although when other people question her about what it means, she does not answer clearly.

Despite appearing to be very prideful, Kaoru struggled with self-esteem problems in the past and created her princely persona to flatter other girls so they may never feel the same way. She also used to be shyer and lamented the fact that she was not strong enough to protect Chisato from their classmates, believing she was an evil and mean person because of one of the roles she acted in.

Trivia

 * She, together with Tomoe, are known as the two most popular girls in Haneoka.
 * Kaoru hosts a corner called "Shakespeare with Seta Kaoru" in the broadcasting room during lunchtime.
 * Kaoru used to call Chisato "Chi-chan" when they were younger and is very embarrassed about that.
 * In return, Chisato calls her "Kao-chan". Kaoru gets flustered whenever Chisato calls her by that nickname.
 * She is the same height as Masuki, and is also the tallest member of Hello, Happy World!
 * Kaoru is scared of both heights and scary things. When asked how she can tolerate them during performances, she mentions that she gets so into character that she completely forgets her fear.
 * Kaoru has mentioned that she is quite athletic, and that her favorite sports are fencing and horseback riding. She has been shown to be quite skilled in the latter.
 * It was revealed that her uncle owns the horses, and one of them is called Silver, while another is called White.
 * Kaoru's theatrical, princely, and flirty personality is a rather open parody of the anime otokoyaku; that is, the anime and manga heroines, inspired by actresses playing male characters from the all-female . This is also emphasized by her close friendship with the very feminine Chisato, who can be compared to musumeyaku, actresses who perform female roles in the same theater.
 * This also explains her popularity with other girls, because otokoyaku is embodied by the metaphorical image of the "ideal man" who can be simultaneously considered as a charming handsome prince and a reliable female friend who understands women's experiences.
 * Kaoru is the only character in the game who has been seen with more than one guitar. Her cards, as well as their chibis in the game, show her posing with at least 3 different guitars.
 * She is also the only guitarist to use, rather than the solid-body instruments the others use.
 * She is the only Hello, Happy World! member to not study at Hanasakigawa Girls' High School.
 * In the Ojamajo Doremi collaboration, her design was based on.
