This paper fixes the bridge layer between the first and second systems of Kasei-Theory. The bridge layer does not introduce an outside, a pre-world structure, world-formation, emergence, activation, or a domain beyond the first system. It reorganizes the first system as a field of peripheral fixations at the limit named Kagen. The peripheral is not exteriority. It is not the failure of a condition to be fulfilled. At the peripheral limit, the judgment of establishment and non-establishment is itself delimited. Kagen is fixed as the condition under which fixation does not hold. Readability, continuity, applicability, boundary, closure, collapse, relation, retention, and trace are not treated as fulfilled conditions or failed conditions. They are fixed as local limits in which the judgment of fulfillment and non-fulfillment no longer holds. Only from this reorganization can the second system proceed as the fixation of local readability conditions under which these limits become readable as reading, time, observation, state, field, interaction, information, phase, life, consciousness, and qualia. No subject is presupposed. No ontology is restored. No causality is introduced. No temporality is introduced.
