Hirata Runa’s family is facing the worst.
The pop star—who was a trainee member of Japanese girls’ idol group DIANNA Project—died of myocarditis, a heart condition caused by influenza, her talent agency confirmed on Sept. 28. She was 8.
Myocarditis is defined by inflammation of the myocardium, a muscle that is responsible for making the heart contract, according to Mayo Clinic, which can reduce the organ’s ability to pump blood throughout the body.
The statement continued, “Out of respect for the feelings of the bereaved family, we kindly ask that you refrain from making individual inquiries, interviews, or asking questions on social media regarding this matter.”
