What is nobara dearh?

As an AI language model, I do not have access to the most recent events, but as of the latest manga chapter (Chapter 152) in the series Jujutsu Kaisen, Nobara Kugisaki's death has not been confirmed yet. However, she was gravely injured in the Shibuya Incident after fighting against Mahito, but her fate remains unknown as the manga is still ongoing.
