  We discuss effective models derived from a supersymmetric model whose
mediation mechanism of supersymmetry (SUSY) breaking is namely mirage
mediation. In this model, light higgsino mass, that is required by the natural
realization of the electroweak scale, is achieved by the unification of the
soft SUSY breaking parameters at the low scale. Besides, we find that extra
Higgs fields are also possibly light in some cases. Then, the effective model
is a two Higgs doublet model (2HDM) with higgsinos, and it is distinguishable
with namely type-II 2HDM which is widely discussed. In this paper, we study the
mass spectrum of SUSY particles and the extra Higgs fields, and summarize the
phenomenology in the effective model. We survey the current experimental bounds
from the LHC and the dark matter experiments as well as the flavor physics.
Then, we point out the expected mass scale of the SUSY particles and reveal the
future prospects for the direct and indirect searches. We also discuss the
difference between our effective model and the 2HDM in the bottom-up approach.
