I only know a specific scene from the anime. A girl wakes up on a roof bleeding and sees a boy badly hurt across from her. Extensions from her body attempt to heal the boy, but then some planes fly overhead and shoot at her, breaking her bond with the boy.
She attempts to crawl to the boy and leaves a trail of blood behind her while doing so. She collapses just before she reaches the boy. The boy wakes up and tells her not to die, but she turns into a crystal and shatters in his arms.
