Japanese composer Cornelius, real name Keigo Oyamada, who was working on the Tokyo Olympics opening ceremony, quit Monday after coming under fire for bullying classmates during his childhood, AP reports. Reports of his past abuse of classmates, including those with disabilities, surfaced online recently and sparked a backlash on social media plus demands for Oyamada’s resignation. Finally, he apologized and quit. A segment of the music Oyamada composed for Friday’s opening ceremony will not be used, and the musician will be also removed from his planned role in the Paralympics opening event.
