  We study a two loop induced radiative neutrino model with global $U(1)$
symmetry at 1 GeV scale, in which we explain the X-ray line at 7.1 keV of dark
matter candidate reported by XMN-Newton X-ray observatory using data of various
galaxy clusters and Andromeda galaxy. We also discuss Higgs sector, lepton
flavor violation processes, and a physical Goldstone boson.
