Kurenai and Shika(naruto) end up on a mission together. At this point they had gotten attacked by enemy ninja from the hidden sound village(naruto) and one had thrown a kunai at Shikamaru(naruto). Kurenai jumped in front of him, taking a kunai to the arm. The pain caused her eyes to glaze over and her chakra became electric that was swirling around her. The ninja gazed fearfully as she stepped foward and proceeded to electricute them. As the last few ran off she passed out from chakra loss and Shikamaru who'd been behind her, caught her in his arms.
