Summary: We give a non-existence theorem for Hopf hypersurfaces \(M\) in complex two-plane Grassmannians \(G_2(\mathbb{C}^{m+2})\) whose normal Jacobi operator \(\overline R_N\) is parallel on the distribution \({\mathfrak F}\) defined by \({\mathfrak F}=[\xi]\cup{\mathfrak D}^\perp\), where \([\xi]= \text{Span}\{\xi\}\), \({\mathfrak D}^\perp= \text{Span}\{\xi_1,\xi_2, \xi_3\}\) and \(T_xM={\mathfrak D}\oplus{\mathfrak D}^\perp\), \(x\in M\).
