  We propose a model with two different extra $U(1)$ gauge symmetries; muon
minus tauon symmetry $U(1)_{{L_\mu}-L_{\tau}}$ and hidden symmetry $U(1)_H$.
Then, we explain muon anomalous magnetic moment, semi-leptonic decays $b\to
s\ell\bar\ell$, and dark matter. In particular, we find an intriguing dark
matter candidate to be verified by Hyper-Kamiokande and JUNO in the future that
request neutrinophilic DM with rather light dark matter mass$\sim{\cal O}(10)$
MeV.
