  We study the moduli-induced gravitino problem within the framework of the
phenomenologically attractive mirage mediations. The huge amount of gravitino
generated by the moduli decay can be successfully diluted by introducing an
extra light modulus field which does not induce the supersymmetry breaking.
Since the lifetime of extra modulus field becomes longer than usually
considered modulus field, our proposed mechanism is applied to both the low-
and high-scale supersymmetry breaking scenarios. We also point out that such an
extra modulus field appears in the flux compactification of type II string
theory.
