This paper resolves the circularity problem identified in Koku Universe v3. 0 (DOI: 10. 5281/zenodo. 20534188). In v3. 0, c = 2*pi*r/tau was defined, which was correctly identified as potentially circular. This paper demonstrates that c is not defined but derived as the conformal invariant of the Riemann Koku-face topology. The identification of center C with circumference C uniquely determines one invariant traversal rate, which is c. This removes c from empirical constants and places it in topological necessities. As a consequence, E = mc² becomes a geometric theorem. Three falsifiable predictions distinguish Koku Universe v3. 1 from standard general relativity.
