Kyoka Jiro, a student at U.A. High School in My Hero Academia, is a self-assured and unbiased character with short purple hair and asymmetrical bangs. Her most noticeable feature is the "ear plugs" that resemble headphone jacks. As a student studying to become a professional hero, Kyoka possesses a unique quirk called "Earphone Jack," which allows her to plug her earlobes into objects to hear their vibrations. This power enables her to detect sounds and even use them as weapons in battle. Kyoka's confident and independent nature makes her a formidable presence among her classmates.
