We report the theoretical study of the three -body system composed of D * D * K * and B * B * K * . We study the interaction of two D * (or two B * ) and one K * by using the fxed center approximation to the Faddeev equations to search for bound states of the three -body system. Since the D * D * interaction is attractive and the D * K * interaction is also attractive, we can expect to obtain the bound state of the three -body system D * D * K * , which is manifestly exotic state with ccs open quarks. Using the same analogy of the D * D * K * system, we also study the B * B * K * system containing the bbs open quarks since both interactions of B * B * and B * K * are attractive. We obtain the bound states of isospin I = 1 / 2, negative parity, and total spin J = 0, 1 and 2.
