  We discuss a model based on dark sector described by non-Abelian $SU(2)_D$
gauge symmetry where we introduce $SU(2)_L \times SU(2)_D$ bi-doublet
vector-like leptons to generate active neutrino masses and kinetic mixing
between $SU(2)_D$ and $U(1)_Y$ gauge fields at one-loop level. After
spontaneous symmetry breaking of $SU(2)_D$, we have remnant $Z_4$ symmetry
guaranteeing stability of dark matter candidates. We formulate neutrino mass
matrix and related lepton flavor violating processes and discus dark matter
physics estimating relic density. It is found that our model realize
multicomponent dark matter scenario due to the $Z_4$ symmetry and relic density
can be explained by gauge interactions with kinetic mixing effect.
