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