  We present a model in which the question about a nature of the dark energy
and the recently raised Hubble tension can be addressed at once. We consider
the electroweak axion in the minimal supersymmetric standard model where the
axion energy density is identified with the observed dark energy. Along with
this, imposing a gauged $Z_{10}$ symmetry makes it possible to have a gravitino
dark matter whose mass amounts to $\sim\mathcal{O}(1)\,\,{\rm GeV}$. We find
that the gravitino with mass $\sim\mathcal{O}(1)\,\,{\rm GeV}$ can be a good
candidate of a decaying dark matter of which decay after recombination can
reconcile discrepancy in local measurements of the Hubble expansion rate
$H_{0}$ and that inferred from the cosmic microwave background observation.
