With the non-Abelian hyper-Kaehler quotient by U (M) and SU (M) gauge groups, we give the massive hyper-Kaehler sigma models that are not toric in the N = 1 superfield formalism. The U(M) quotient gives N{exclamation_point}/[M{exclamation_point}(N - M){exclamation_point}] (N is the number of flavors) discrete vacua that may allow various types of domain walls, whereas the SU (M) quotient gives no discrete vacua. We derive a BPS domain-wall solution in the case of N = 2 and M = 1 in the U(M) quotient model.
