Query: Radiative neutrino model with semi-annihilation dark matter   We propose a Two-Loop induced radiative neutrino model with hidden gauged
$U(1)$ symmetry, in which a dark matter of Dirac fermion arises. The relic
density gets contribution from annihilation and semi-annihilation due to a
residual $\mathbb{Z}_3$ parity. After imposing the requirement of neutrino
oscillation data and lepton flavour violation bounds, we find out that the
semi-annihilation plays a crucial role in order to satisfy the relic density
constraint $0.117 < \Omega h^2 < 0.123$, by proceeding near either one of two
deconstructive scalar resonances. Our numerical analysis demonstrates the
allowed region for the DM-Scalar coupling with the DM mass in $(80, 400)$ GeV.
