We report measurements of the flux-integrated \(\bar{\nu}_\mu\) and \(\bar{\nu}_\mu+\nu_\mu\) charged-current cross-sections on water and hydrocarbon targets using the T2K anti-neutrino beam, with a mean neutrino energy of 0.86 GeV. The signal is defined as the (anti-)neutrino charged-current interaction with one induced \(\mu^\pm\) and no detected charged pion nor proton. These measurements are performed using a new WAGASCI module recently added to the T2K setup in combination with the INGRID Proton module. The phase space of muons is restricted to the high-detection efficiency region, \(p_{\mu}>400~{\rm MeV}/c\) and \(\theta_{\mu}
