  We report results of masses and decay constants of light and charmed
pseudo-scalar mesons using lattice QCD with M\"obius domain-wall fermions.
Using this formulation we are able to compute pseudo-scalar decay constants
through the pseudo-scalar density operator as well as with the axial-vector
current. Results are shown from several lattice spacings and pion masses
between 230 MeV and 500 MeV. We present an analysis of these results at
different quark masses to show the chiral properties of the light mesons masses
and decay constants.
