Kazuki Tomori (友利 一希, Tomori Kazuki) is Nao's older brother who once had the ability to change the air vibrations. Previously he was a member of a band which was going to make a contract with a record company, but it was cancelled due to their mother's begging for Kazuki and Nao to enter a certain boarding school. It is revealed that the school has relations with a scientist who later did experiments on Kazuki. He has stayed at the hospital until now and for some time does not even recognize Nao as his sister. However, recently, Yū takes Sala Shane to Kazuki's hospital to meet him, with the hope that he will regain consciousness, and he does.
Appearance
Kazuki has brown-yellowish hair and blue eyes like Nao's. Prior to having been experimented upon by scientists, he had a normal and expressive face. But after that and having lost his special ability, he now has a duller, hollow expression with lidded, unfocused eyes.
Personality
Kazuki is seen generally as caring, as he looks out for his younger sister. He is also very goal-oriented, getting upset when he is unable to sign a record label after practicing guitar for many years. After being tested on by scientists, Kazuki continues to attempt to compose music, but is unable to reason with others for the most part.
Ability
Kazuki, prior to being taken away by scientists.
Kazuki's ability is to control surrounding air vibrations. While he used it to get desired sounds, scientists believed it could be better put to use by jamming signals.
