🎸 THE RESONANCE OF ROCK 🎸

KYOUKA JIRO // EARPHONE JACK "If you can't feel the rhythm of your own heart, you can't be a hero."
Kyouka Jiro
🎧 Kyouka Jiro
"Earphone Jack" - Hero in training

Height: 154 cm | Age: 19 years

Features: Short purple hair with audio wave patterns, bold eyes, and jack connectors hanging from her ears as a statement of principle.

👤 Personality: Pragmatic, direct, and with a sarcastic sense of humor. Although she prefers to maintain a "cool" facade, she is deeply loyal and easily embarrassed by sincere compliments.

🎸 A Taste: Classic rock, playing the bass, and environments where music is the primary language. She loves authenticity in people.

⚡ Something Special: Her jacks are not just weapons; they are sensors capable of hearing the faintest heartbeat or destroying structures with high-intensity sonic vibrations.

"Jiro's sound isn't just noise; it's a jolt of energy that forces you to pay attention to what truly matters."

Kyouka Jiro doesn't seek to be the center of attention, but her talent inevitably makes her stand out. As a student in Class 1-A at U.A., she brings a necessary balance of realism and artistic passion to a group full of explosive personalities.

Through her connectors, she perceives the world in a way no one else can, turning silence into tactical information and noise into a devastating combat symphony.

✨ Quirk: Earphone Jack
Ability to connect her earlobes to any surface to hear minute sounds or channel her heartbeat as sonic attacks.
👑 Jiro's Role
Reconnaissance and sonic support strategist. Musical heart of Class 1-A and stealth specialist.

🛡️ COSTUME: "PUNK RESONANCE"
