Motivated by the recently observed hypernucleus (Kiso event) $^{ 15}_{ \Xi}$C ($^{ 14}$N$+\Xi^-$), we identify the state of this system theoretically within the framework of the relativistic-mean-field and Skyrme-Hartree-Fock models. The $\Xi N$ interactions are constructed to reproduce the two possibly observed $\Xi^-$ removal energies, $4.38\pm 0.25$ MeV or $1.11\pm 0.25$ MeV. The present result is preferable to be $^{ 14}{ \rm N}({ \rm g.s.})+\Xi^-(1p)$, corresponding to the latter value.
