Motivated by the recently observed hypernucleus (Kiso event) C-15(Xi) (N-14 + 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 +/- 0.25 MeV or 1.11 +/- 0.25 MeV. The present result is preferable to be N-14(g.s.) + Xi(-)(1p), corresponding to the latter value.
