Abstract: We show that the $K^* 21430$, $K^* 31780$, $K^* 42045$, $K^* 52380$and a not yet discovered $K 6^*$ resonance are basically molecules made of anincreasing number of $ ho770$ and one $K^*892$ mesons. The idea relies onthe fact that the vector-vector interaction in s-wave with spins aligned isvery strong both for $ ho ho$ and $K^* ho$. We extend a recent work, whereseveral resonances showed up as multi-$ ho770$ molecules, to the strangesector including the $K^*892$ into the system. The resonant structures showup in the multi-body scattering amplitudes, which are evaluated in terms of theunitary two-body vector-vector scattering amplitudes by using the fixed centerapproximation to the Faddeev equations.
