The three analytic functions needed for the fixed modulus-five input.

Every nonprincipal character modulo five is determined here by its value at two, which is one of -1, I, or -I. Its L-function is an explicit finite linear combination of the existing Hurwitz zeta functions. The final identity identifies the corresponding Mangoldt Dirichlet series with the negative logarithmic derivative on the half-plane of absolute convergence.
