Description
Seta Kaoru is the guitarist for Hello, Happy World! and a first-year Theatre Department student in the Acting Program at Yotsuba Women's University. Towering at 170 cm, she is the tallest member of her band and among all featured characters. Her angular face features slanted crimson eyes and long purple hair, typically styled in a ponytail with chest-length forelocks. Kaoru favors a boyish yet formal fashion sense, often seen in high-collared shirts with vests, vertically striped pants, and pearl necklaces, switching to gray sweaters with scarves in winter and front-tie floral shirts in summer.
She embodies a flamboyant, theatrical personality, calling herself a "prince" and addressing other girls as "princesses" or "little kittens" (子猫ちゃん, koneko-chan). Kaoru uses elaborate, sometimes pretentious language, quoting philosophers like Shakespeare and Nietzsche—occasionally inaccurately, such as misstating Nietzsche's gender. Her signature catchphrase "fleeting" (儚い, hakanai) peppers her speech despite her inability to define it clearly. This princely persona, developed through theater starting in middle school to overcome childhood self-esteem issues rooted in her failure to intervene when her friend Chisato Shirasagi was bullied, represents her genuine self.
Beneath the extravagance, Kaoru shows keen emotional intelligence and perceptiveness. She easily recognizes others' emotional states, like intentionally making Saaya laugh to ease nerves or being the only band member to grasp Kokoro Tsurumaki's motivations during key moments. Prioritizing others' happiness, she accommodates impossible fan requests for play revisions and supports peers from the sidelines with steadfast belief rather than direct encouragement, a people-pleasing tendency linked to her guilt over Chisato's past.
Despite her intelligence, Kaoru displays air-headed tendencies comparable to bandmates Kokoro and Hagumi Kitazawa, such as repeatedly pushing pull-only doors or communicating across language barriers using only gestures and her catchphrase. She fears heights and horror elements, though acting immersion lets her disregard these phobias during performances. Other quirks include difficulty waking up and hosting the children's storytelling segment "Seta Kaoru's Masterpiece Theater" on the band's streaming channel.
Narrative developments show Kaoru participating in Hello, Happy World!'s extreme activities despite her fears, like a skydiving performance where she faints mid-air due to acrophobia. Her dynamic with Chisato remains significant, featuring mutual childhood nicknames ("Kao-chan" from Chisato, "Chii-chan" from Kaoru) that visibly embarrass her when used publicly. Athletic hobbies include fencing and horseback riding, skills honed using her uncle's horses, Silver and White. She uniquely uses multiple semi-hollow/hollow-body guitars.
Within Hello, Happy World!, Kaoru is positioned as one of the "three idiots" alongside Kokoro and Hagumi, contributing to comedic scenarios like Michelle Land's mascot confusion. Her popularity among female characters like Uehara Himari and Ushigome Rimi, who often blush around her, aligns with the "otokoyaku" trope, referencing actresses performing male roles in Takarazuka Theater, symbolizing an "ideal man" blending princely charm with empathetic female friendship.
