Lattice quantum chromodynamics (QCD) simulation with chiral fermions is an attractive tool for studies on the non-perturbative field theory of strong interaction. However, it requires a large number of computer assets and is computationally very expensive. We describe the propagators of the π meson and the ρ meson constructed from the truncated overlap fermions. These propagators are calculated using lattice QCD simulations with a quench approximation. We indicate the dependence of the five dimensions for the mass of the π and ρ mesons. The residual mass at the chiral limit is also investigated.
