A student in Class 1-A. Outspoken, snarky, and typically unenthusiastic, Jirou also has an interest in rock music (something sheโs actually quite embarrassed about).
Her quirk is "earphone jack", which grants her the unique "earlobe jacks" that she can extend at will. She can plug the earlobe jack onto any surface to increase her sound reception from the distance, as well as using it to "amplify" her heartbeat to create an earthquake-like shockwave.
