  The \sigma(600) and \kappa(900), observed in the phase shift analyses,
satisfy rather well the mass and width relation predicted by the SU(3)LsM and
the SU(3)LsM with the vector and axial-vector meson nonets, and deserve to be
the members of scalar \sigma-nonet, together with the observed resonances
a_0(980) and f_0(980), as a chiral partner of pseudoscalar \pi-nonet. In the
phase shift analyses an introduction of repulsive background phase \delta_{BG}
is essential, whose origin has a close connection to the \lambda\phi^4
interaction in LsM. It is argued that the members of this \sigma-nonet,
"Chiralons", have different properties and should be discriminated from the
conventional ^3P_0-qqbar-scalar nonet.
