  It is often argued that the minimal supersymmetric standard model has O(100)
free parameters and the generic parameter region is already excluded by the
null observation of the flavor and CP violating processes as well as the
constraints from the LHC experiments. This situation naturally leads us to
consider the case where all the dangerous soft supersymmetry breaking terms
such as the scalar masses and scalar couplings are absent, while only the
unified gaugino mass term and the mu term are non-vanishing at the grand
unification scale. We revisit this simple situation taking into account the
observed Higgs boson mass, 125 GeV. Since the gaugino mass and the mu term are
fixed in order to explain the Higgs boson and the Z boson masses, there is no
free parameter left in this scenario. We find that there are three independent
parameter sets exist including ones which have not been discussed in the
literature. We also find that the abundance of the dark matter can be explained
by relic gravitinos which are non-thermally produced as decay products of the
SUSY particles while satisfying constraints from Big Bang Nucleosynthesis. We
discuss the effects of the gravity mediation which generically give
contribution to the soft terms of the order of the gravitino mass. It turns out
that newly found parameter set is preferable to explain the Higgs boson mass as
well as the gravitino dark matter while satisfying the constraints from the
electric dipole moments of the electron and the nucleon.
