As the older brother of Nao, this former musician once possessed a unique ability to manipulate air vibrations to enhance his guitar performances. However, following traumatic scientific experimentation, he now resides in a hospital, having lost the ability to recognize his own sister. His tragic transformation and musical legacy serve as the primary inspiration behind Nao’s deep devotion to the band ZHIEND, linking his lost talent to her musical journey.
