Sakura's Inner screamed inside her mind as her consciousness died out. The main body was dying and the Inner felt each cell burning for more oxygen, each muscle tissue pumping out its last energy reserves to survive, each nerve ending sending out distress signals to the brain as the organs slowed in activity. And it was frightening. To feel your outer shell disappear around you while the body screamed from pain, and all the Inner could do was watch as everything collapsed around her; it was truly terrorizing.
But she couldn't let it end. She wouldn't let it end like this. So the Inner did what she did best : she got angry. Very angry. Anger was her energy, and the more energy she had, the stronger Sakura's survival instincts would be. And the more the Inner gained in strength and size, the more Sakura's conscious projection shrunk and paled with her body's shortening lifespan.
So the Inner screamed and punched into the emptiness around her, shouted back at the weeping cries of the body, slammed herself against the confines of the mind she shared with the consciousness, letting the body feel her excess of energy, baiting it to use this source of power while it was slowly dying.
It didn't need much more prodding than that. It was desperate to survive, and in the blink of an eye, the Inner was knocked back into the veiled part of the mind as Sakura's Conscious awoke with a gasp, chakra enveloping her as she quickly formed hand seals that would save her life.
