We present numerical simulation using overlap fermion action with two dynamical flavors on a 163 32 (0.12 fm)4 lattice. We calculate pseudo-scalar masses and decay constants and focus on their chiral properties. Using the lattice data with exact chiral symmetry, we test the one-loop chiral perturbation theory predictions including finite size effects.
