The narrow mesons, DsJ*(2317) and DsJ(2460), observed recently in the final states Ds+ pi0 and Ds*+ pi0 are pointed out to be naturally assigned as the ground-state scalar and axial-vector chiral states in the csbar system, which would newly appear in the covariant U~(12) hadron-classification scheme proposed a few years ago. We predict the comparatively large electromagnetic decay widths to other models, which are due to the intrinsic electric dipole moment. The SELEX state DsJ(2632) is also able to be assigned to the P-wave chiral state with JP=1- in the U~(12)-classification scheme.
