Kyoka Jiro—also widely recognized by her hero alias “Earphone Jack”—is one of the standout characters in the beloved anime series My Hero Academia, known to fans around the world as Boku no Hero Academia.

And honestly, with her unique abilities and strong sense of self, it’s no surprise that she’s quickly become a fan favorite.
One thing that really sets Kyoka Jiro apart is her Quirk—literally. She can plug her earlobes into any surface, using them like actual audio jacks to amplify sound. Whether it’s boosting ambient noise for reconnaissance or generating powerful sonic blasts in battle, Kyoka Jiro’s ability is both creative and highly practical. This makes her not only a versatile fighter but also an essential support member during team missions. In fact, you could say Kyoka Jiro turns everyday objects into instruments of justice—quite literally, since music plays such a big role in her life.
But beyond the flashy combat applications, there’s more to Kyoka Jiro than meets the eye. Sure, she comes off as cool, a bit edgy, and maybe even a little intimidating at first glance. But dig a little deeper, and you’ll find that Kyoka Jiro is genuinely kind-hearted. She often goes out of her way to check in on her classmates, especially those who seem anxious or overwhelmed. Her empathy and quiet strength make her someone others naturally gravitate toward, even if she doesn’t always seek the spotlight.
And speaking of spotlight—let’s talk about her music. Kyoka Jiro isn’t just a hero-in-training; she’s also a talented bass guitarist.
