We have discussed the possibility where the observed deviations in the b → sµ + µ − data including the variables R K ( * ) are addressed, in the context of vectorlike compositeness (or so called hypercolor). Major virtues of this type of scenario are as follows: (i) The theory is manifestly gauge anomaly free; (ii) A desirable form in flavor-changing interactions is naturally realized by exchanges of the hypercolor vector ρ mesons, which are composite spin-1 particles being analogous to the
