Despite doctors' efforts, the child could not be saved. Family members noted that Runa passed away peacefully and without suffering.### Creative Journey and Dedication to the Stage

Born on April 16, 2018, Hirata Runa dedicated a significant portion of her short yet vibrant life to stage performance. As a member of the DIANNA Project, an organization focused on training and developing young talents, she spent roughly a third of her life performing. Just five days before the tragedy, on September 20, the young artist took to the stage for the last time, later sharing her joy on social media by posting a smiling photo and thanking everyone for their support.

The farewell ceremony for Hirata Runa was held in a private, intimate format attended only by close family members. The family and producers appealed to the public and fans to respect their privacy and refrain from intrusive comments on social networks. Organizers urged fans to forever keep a warm memory of the girl who genuinely loved the stage and brought joy to those around her.

 In the information space and social networks surrounding the tragic departure of the young artist, certain discussions arose regarding the exact timing of the information disclosure. Some foreign blogs and fan communities spread rumors that the family had allegedly concealed the fact of hospitalization for a long time. However, official sources, including the DIANNA Project agency and specialized media, refuted these speculations, confirming that the delay in the official statement was due solely to the need to organize a private funeral and the heavy emotional state of the relatives.
