With the non-Abelian hyper-Kähler quotient by U ( M ) and SU ( M ) gauge groups, we give the massive hyper-Kähler sigma models that are not toric in the N =1 superfield formalism. The U ( M ) quotient gives N !/[ M !( N-M )!] ( 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.
