Ouroboros Spine Starburst

Kau was always ready for a fight, best if there were no limits on, how far one could go. But she also had learned the limits of her strength and, when action was not going to bring the desired result. She may not have as much energy as others, but she was mastering the craft of spending it wisel. It was clear that her initial plan of dragging Samani off the stick was was not going to work. They were roughly the same size, her sister was better built and heavier and practically inmovable, if she decided so. Chomping on her nape for too long or hard would mean she would eventually scream and an adult would intervene. And Kau had endured enough of wolf-manner-learning tactics for especially naughty children not to wish to have a lesson of it now too. 

Therefore she decided to let go of her sister, clambered over her and then got directly in her face, trying to lie on top of her and thus make her move.
