This paper fixes Ka within the third system of Kasei-Theory. Ka is not introduced as possibility, modality, potentiality, capacity, capability, ability, optionality, openness, accessibility, latent power, future availability, executable power, modal alternative, ontological openness, origin, ground, foundation, or completion. Ka does not establish possibility, modality, potentiality, capacity, capability, ability, optionality, openness, accessibility, latent power, future availability, executable power, modal alternative, ontological openness, origin, ground, foundation, or completion. Ka is fixed only as decompositional fixation without possibility. Decompositional fixation does not define Ka, explain Ka, derive Ka, or convert Ka into a foundational term. This fixation does not establish possibility, modality, potentiality, capacity, capability, ability, optionality, openness, accessibility, latent power, future availability, executable power, modal alternative, ontological openness, origin, ground, foundation, or completion. The paper prevents Ka from being reduced to possibility, modality, potentiality, capacity, capability, ability, openness, accessibility, latent power, future availability, executable power, ontological openness, origin, ground, foundation, or completion. Ka is not the ground of Kasei-Theory, is not the origin of Kasei-Theory, does not explain the first system, does not explain the second system, and does not complete the post-II threshold. Kasei-Theory does not establish determinism. Fixation is not determination. Constraint is not necessity. Maintainability is not predestination. Non-transition is not modal exclusion. No possibility is presupposed. No modality is introduced. No potentiality is established. No capacity is secured. No capability is introduced. No ability is introduced. No ontological openness is restored. No origin is established. No foundation is established.
