  Dynamical chiral symmetry breaking in a QCD-like hidden sector is used to
generate the Planck mass and the electroweak scale including the heavy
right-handed neutrino mass. A real scalar field transmits the energy scale of
the hidden sector to the visible sectors, playing besides a role of inflaton in
the early Universe while realizing a Higgs-inflation-like model. Our dark
matter candidates are hidden pions that raise due to dynamical chiral symmetry
breaking. They are produced from the decay of inflaton. Unfortunately, it will
be impossible to directly detect them, because they are super heavy
($10^{9\,\sim\,12}$ GeV), and moreover the interaction with the visible sector
is extremely suppressed.
