[Sword Doctrine of Entropy]: Whenever 相手's hit by 自分, their essence unravels, turning into pure chaos, rendering recovery impossible. [Split Void Empty Valley]: In the final clash, 自分 gets enlightened, learning the true purpose of the Doctrine lf Entropy. Thus, in one slash, 自分 unravels reality into [Purity], creating a valley of [Pure Emptiness] in its wake, utterly bypassing 相手's defences.
