In this chapter, we learn that the siblings are on the side of their friend, the mountain man. The mountain man asks the siblings if they're using their rock as a shield against his attack. They're hiding behind it because they don't want to be caught in the crossfire. The brother says he's only teaching his friend a lesson. He'll let him live to see the new world, and he'll thank him for it. He says that the girl has awakened her power, and that she'll understand how unfair the world is once she's treated like a freak. Why should a bunch of incompetent, mediocre people have power and wealth? Why should an ability wielder have to hide, and be treated as monsters? That girl has a special physique, and the sage can use her to summon a calamity body. The sage can then use that body to transform the world. The brothers say they'll help the sage stop his attack, but that they still need brains to do it.
