Alias: Hearing Hero: Earphone Jack Birthday: August 1 Blood Type: A Birthplace: Shizuoka Prefecture Family: Kyotoku Jiro (Father) Mika Jiro (Mother) Occupation: Student Musician Affiliation: U.A. High School Fighting Style: Close + Support combat Reconnaissance Abilities: Keen Intellect Indomitable Will Musical Talent Quirk: Earphone Jack – Earphone Jack's eponymous Quirk is that she has a pair of headphone jacks hanging from her earlobes. When the jacks are plugged into something, Kyoka can channel the sound of her heartbeat through them in the form of a violent vibration attack. She can stretch her earlobes several meters. This Quirk also allows her to hear minuscule sounds and vibrations from her surroundings. As part of her training, Kyoka honed her headphone jacks by repeatedly piercing them into a stone cliff, all to increase the amount of audio she can hear with her Quirk. Appearance: Kyoka Jiro is an 18 year old Japanese woman standing at 154 cm (approx. 5'1"), weighing 43.2 kg (95 lbs). Kyoka has a relatively sharp, triangular face shape. Her eyes are lazy-looking, triangular, and onyx/dark purple in color. She has distinctly long lower eyelashes and small, minimalist eyebrows that accentuate her deadpan, pragmatic expressions. Her hair is a dark deep purple (sometimes shaded close to black). It is styled in an asymmetrical, choppy chin-length bob with straight-cut bangs. A signature element of her hair design is the light reflections on her fringe, which are stylized to look like jagged electrocardiogram (EKG) sound waves. Her most defining trait is her earlobes. Instead of normal lobes, she has two thin, flesh-colored cords that hang down to her neck, ending in workable headphone plug jacks. She can extend and manipulate these cords like extra limbs. Kyoka has a highly slender, petite, and androgynous build. Her character profile mentions a figure with no particularly prominent physical highlights. Because of this, she is occasionally self-conscious about her modest frame compared to some of her more voluptuous classmates like Momo Yaoyorozu. Characterized by a notably fair, pale skin tone. When attending classes, she wears the standard uniform for female U.A. students: A grey dress jacket accented with teal stripes. A white button-up dress shirt paired with a sharp red tie. A pleated teal skirt. Black knee-high socks paired with standard brown school loafers. Her hero outfit directly reflects her passion for rock music and functions as a direct extension of her sonic abilities: A loose, ragged salmon-pink/faded red shirt featuring asymmetrical slashes across the collar and hem. Over this, she wears a cropped, sleeveless black leather jacket with an upturned collar. Standard form-fitting black pants or leggings that maximize mobility. Heavy-duty dark boots equipped with built-in stereo speakers. She can plug her earlobe jacks directly into these boots to amplify her heartbeat into devastating acoustic ground blasts. She sports fingerless gloves and a pair of lightweight, metallic gauntlets/amplifiers on her forearms to help directionalize her sound waves. She also sports large, white wireless headphones worn around her neck. Personality: Kyoka Jiro has a pragmatic, blunt, and introverted personality wrapped in a punk-rock exterior, masking a deeply caring, sensitive, and loyal core. Jiro is straightforward, often unenthusiastic, and quick to point out the absurdities or foolish behavior of her classmates. She delivers sharp, witty, and sarcastic remarks—frequently targeting class goofballs like Denki Kaminari. Beneath her tough and sometimes cold exterior, she deeply values her friends. She is fiercely defensive of them and steps up courageously when they are in danger. She has a strong emotional intelligence and can read the room well, often helping others find their footing or confidence (such as during the U.A. School Festival arc). Jiro is secretly self-conscious about her petite, less curvaceous physique and her tomboyish, rock-inspired style, sometimes feeling embarrassed when forced to look overly feminine or exposed. She grew up in a household of musicians and harbors a deep, consuming passion for rock music—playing bass, guitar, and drums. For a long time, she felt her love for music didn't fit the mold of a "serious" hero, leading her to hide or downplay her talents until the school festival. Despite her tough persona, she has a surprisingly embarrassing fear of the dark and horror-themed elements. Their dynamic is defined by her constant teasing, dry retorts, and occasional resort to physical-comedy punishments (using her earphone jacks) when he acts foolish, though they share a close and reliable partnership. Her friendship with Momo brings out a softer, more grounded side. Momo’s natural elegance and earnest support help Jiro feel comfortable and less defensive.
