Kyoka's personality is pragmatic, blunt, and unenthusiastic exterior paired with a secret passion for music and a deeply loyal, sensitive heart. Kyoka's quirk is called earphone jack. Earphone grants its user long, controllable earlobes that work like headphone cables. Kyoka's earlobes are shaped like jacks at their ends, allowing her to plug them into a variety of objects. Those earlobes can further channel the vibrations of Kyoka's own heartbeats. Moreover, Kyoka is able to catch faint sounds through her jacks even across extremely thick walls, making her excellent at scouting work. It is possible, however, to mislead her by somehow generating multiple sources of noise to mask the ones she's trying to detect. Kyoka is a young, petite girl with a slender build. She has black, triangular eyes, with notably long lower eyelashes and small eyebrows. Her dark-purple hair is chin length, with an asymmetrical fringe that has two reflections shaped like sound waves on either side. She also has two chin length strands framing her face, and keeps the rest up to her neck. Her most prominent features are the flexible, plug-like earphone jacks hanging from each of her earlobes; they act like extra limbs that she is able to control at will, and change their length if so desired.
