響野 里澄

A genius music prodigy, Rhythmy (a homonym of 'Rizumi') devotes all her energy to music composition. She is seen wearing headphones all the time, which makes people afraid to talk to her. She also does not talk much at all. As a result of her personality, she does not have many friends at school.

Rhythmy has excellent sense of hearing, as she can hear and distinguish every kind of sound, regardless of how far it is. Her incredible (and sometimes too good) sense of hearing is part of reasons why she has to wear headphones. She also likes quiet places as she will not have to hear and get disturbed by all kinds of sound.
